Interview with Marine Biologist/Veterinarian Claire Simeone of Marine Mammal Center

Claire Simeone DVM at work
by Kavi Dolasia, Tamalpais High School

Claire Simeone, DVM is a Conservation Medicine Veterinarian at The Marine Mammal Center in Sausalito, California, as well as National Marine Fisheries Service in Washington, DC. In addition to taking care of sick marine mammals that come for treatment at the rehabilitation center, she also travels nationally to respond to Unusual Mortality Events, develops international training programs, and works on the Marine Mammal Health Map, which provides a centralized reporting system for marine mammal health data.

To learn more about her profession, we interviewed her.

1. How did you first get involved in marine biology and the field of veterinary?

I knew I loved both animals and science from an early age. Biology was one of my favorite subjects in high school, and I decided to study neurobiology in college. I started as a volunteer at a veterinary clinic in high school, and continued to work as a veterinary technician through college and veterinary school.
My Dad was an environmentalist, and gave me a deep respect for wildlife and the ocean. I began to be exposed to many different careers that veterinarians could have, and realized that I could combine my love of science and wildlife conservation in a job. My career has been a dream come true.

2. How was your experience training with SeaWorld San Diego?

Much of what I was taught about marine mammal medicine came from my mentors at SeaWorld San Diego and the Navy Marine Mammal Program.SeaWorld has been in the media spotlight recently, and there are a variety of opinions about marine mammals in captive care. In my experience, the animals receive the highest quality medical care, and each person that works with them is incredibly invested in caring for these animals in the best way possible. Medicine is continually advancing, and one of the best parts of my job is that I get to be a part of the pioneering science that improves the health of marine mammals everywhere.

3. What is your favorite “project” you have worked on within the Marine Mammal Center?

One of the most exciting projects has been to be a part of Ke Kai Ola, our hospital for endangered Hawaiian monk seals. We work with partners like the National Marine Fisheries Service and the Coast Guard to rescue young animals that would otherwise not survive on their own, and rehabilitate them in our hospital. We use the knowledge we’ve gathered over 40 years of caring for other seals like elephant seals and harbor seals, and apply it to working with this rare species. Since our hospital opened in 2014, we have rehabilitated more than 1% of the entire population. The best news is that during their last estimate, it looks like the population is starting to increase! This is an amazing way for me to be a part of a project that is literally saving a species.

4. What are the best parts of your job? What are the worst?

There are so many amazing parts of this job! First, every day is different. I never know if I’ll be performing surgery in the hospital, or presenting at a scientific conference, or examining a healthy seal in the wilds of Alaska.

Second, I’m lucky to be able to work with such interesting animals. In addition to being entertaining characters, they’re always teaching us something new about themselves, or the ocean. Third, I love being able to share our science and discoveries with the world. So many of the things my fellow scientists are working on are fascinating, and I am thankful that I’m in a position to share this with so many people.The most difficult part of my job is dealing with the realities of working with sick animals and a sick ocean. We can’t save every animal, and sometimes working with so many sick animals can be sad and overwhelming. That’s why I work to balance negativity with positive conservation stories.

5. Why are you so passionate about ocean conservation?

As we become a global society, our Earth is becoming a smaller place. It used to feel as though our oceans were limitless, with unending stocks of fish. We are now acutely aware that we humans have a significant impact on the ocean. Many of the patients we see at The Marine Mammal Center are impacted by human actions – entangled in ocean trash or struck by a ship.But just as we have the capacity to have a negative impact, we also have the capacity to save our oceans. Marine mammals hold secrets about human health, and the health of the ocean. I feel a responsibility to share these secrets so that every person has the information they need to conserve this planet we share.

6. What advice would you give to someone who aspires to work in a similar field?
It’s a big job to save the ocean! We need lots of people working hard on many different projects. My biggest advice would be to stay open-minded about possibilities. I knew I loved biology, but it was a Spanish teacher who suggested I do an exchange during high school, and now I use Spanish when I work on international marine mammal projects. You never know how your skills will come in handy in the future. Get out there and volunteer at places that are doing interesting work. The Marine Mammal Center has a Youth Crew program for students ages 15-18, and allows you to get hands on experience rehabilitating marine mammals.

The Intelligent Sea Lion

The Intelligent Sea Lion
By Shoshana Harlem, Terra Linda High School


The brain of a sea lion!

Can an animal still be a good scientist without thumbs? The answer is yes, because the sea lion is in this exact situation. Although sea lions have no thumbs, they have a big brain. Their brain is about the same size as a chimpanzee brain. They are one of the few mammals besides dolphins, humans, elephants, and whales that have brains that weigh more than 1.51Lbs. Scientists are not sure why the sea lion has such a big brain, but they think that it might be because they have a large body size and those two usually correspond. Other theories have to do with the weightlessness of the marine environment, coping with cold water temperature, or perhaps it is just a random outcome of evolution.

The sea lion’s brain consists of different regions for processing information from their whiskers. A specific, corresponding, area in the brainstem is devoted to each whisker on the sea lion’s nose. The areas in their brain that are responsible for processing touch information from the whiskers and the skin are the thalamus, cortex, and brainstem. Likewise, the human brain has specific areas which correspond to the individual fingers of a person. The whiskers on the sea lion assist with sea lion behavior and sensation. There are certain areas in the sea lion’s brain which are made for processing touch sensations from their flappers and tail. Scientists don’t know a lot about the sea lions cerebral skills. The sea lion has a particular part of their brain called the Bischoff’s Nucleus, which is very well-developed. It is surprising that sea lions have this part of their brain because it is usually found in animals with prominent tails such as kangaroos, raccoons, and whales. But the sea lion’s tail is tucked and small behind its hind flippers.
A sea lion’s very important whiskers!
On each side of a sea lion’s face, are 38 whiskers. The whiskers can grow to be eight inches in length and are really sensitive. The sea lion produces more nerve fibers than any other animal in the animal kingdom. Its whiskers can be helpful in many ways too. One way is that they use their whiskers is to spot a fish by looking for changes in the flow of the water. They can find fish that are swimming up to 590 feet away from them. The whiskers can also help a sea lion know the differences between shapes and sizes up to as far as a fraction of a centimeter.
Amazingly, the sea lion’s brain is capable of higher cognitive functioning. A sea lion can play a game of Concentration. Through trial and error, they can match unrelated symbol pairs. They can also recognize signals, which is really useful in the wild. In this way they can find food, and know if someone is their friend or their enemy. Sea lions also have the ability to think logically. The can know that if a=b and b=c, then a=c.

To learn more about why sea lions are such good scientists, come to the Marin Science Seminar at Terra Linda High School in room 207 on Wednesday, February 8, 2017. Claire Simeone DVM of the Marine Mammal Center in Sausalito will be speaking. Join us and learn!

Saving Our Ocean Friends: An Interview with Dr. Claire Simeone of the Marine Mammal Center

by MSS Intern Isobel Wright, Tamalpais High School

From sea lions with cancer to stranded motherless seal pups, Dr. Claire Simeone knows just what to do. Dr. Simeone works as a Conservation Medicine Veterinarian at The Marine Mammal Center in Sausalito, California and at the National Marine Fisheries Service in Washington, DC. In addition to tending to sick animals, she travels the world to attend Unusual Mortality Events, international training programs, and works on the Marine Mammal Health Map. Dr. Simeone attended the University of Maryland College Park to receive her BSc in Physiology and Neurobiology, and graduated from veterinary school at Virginia Tech. Read the following interview to learn more about life at the Marine Mammal Center and working with animals. 
Claire Simeone, DVM
            Could you walk me through your typical day at The Marine Mammal Center?
One of the best things about working at The Marine Mammal Center is that every day is different. Some days, you’re caring for harbor seal pups that have been separated from their mother. Another day, you’re treating California sea lions with cancer. You might be medicating elephant seals that are dying of lungworms. Some days, you’re treating all of those animals, plus caring for the two hundred additional animals that are ALSO onsite. 
As a veterinarian, I usually start my day walking around the pens to check in on all of the animals on-site, and then our team starts procedures, which include blood draws, x-rays, and surgeries. If animals die, we perform post-mortem exams to determine why they died. At the same time, our volunteer crews (more than 1,000 committed people!) are preparing fish, feeding the animals, and cleaning their pens. Our night volunteer crews take care of the animals into the night, and the veterinarians and technicians are on-call 24 hours a day to make sure all of the animals receive the care they need.
What are the best and worst parts of your job?
There are so many best parts of my job. First, I’m lucky to be able to travel around the world to care for marine mammals and learn more about them. Second, I really feel that I’m making a difference with the work I’m doing – whether it’s saving a seal pup or training the next generation of marine mammal veterinarians. Third, I’m constantly learning new things – about marine mammals, their habitats, and what affects their health. 
Because I do work with animals, a difficult part of the job can be seeing animals that are suffering, often because of things humans do – but it helps to know that we are doing everything we can to bring that animal back to health.
What does it feel like to rescue an animal?
Imagine getting a call from someone who was on vacation, and saw a California sea lion that had fishing line around his neck. First, you feel focused – you take down the description of the animal from the citizen, check your maps, and plan out your strategy. Your rescue volunteers have confirmed that this animal is one you’ve been watching for months, and he’s asleep on the beach. You load up the truck, and make the drive to meet your team. You feel hopeful – he’s still snoring away. Holding your breath, you sneak up slowly, and then with a leap you throw the net over his head. He roars as he jumps up and finds himself trapped. With swift action your team boards him into a carrier, and as stealthily as you came, you load him into the truck. You feel elated as you watch him resting calmly on the way home. 
After a quick procedure to remove the line, it’s clear his wound will heal on its own, and he’s ready to go back to the ocean. After driving him back to the beach, you open the carrier, and he strides out into the waves and dives under the break. You feel proud that you’ve saved this animal’s life, and returned him to his ocean home. 
What’s the most common injury/disease you see in marine mammals? How can we prevent this?
Unfortunately, we commonly see injuries that are due to something called human interaction – entangled in fishing line, nets, or plastic packing straps; ingesting pieces of plastic; struck by a boat; or gunshot. In 1972 the Marine Mammal Protection Act was passed, making it illegal to harass or harm a marine mammal. However, many marine mammals are still harmed in passive ways from our trash or discarded items. You can prevent these entanglements by properly disposing of plastics, and helping to keep beaches clean by picking up any trash you see. Just a few weeks ago the annual International Coastal Cleanup Day brought 54,000 volunteers to California’s coasts. They removed over 680,000 pounds of trash in one day!
What level of education and experience do you need to obtain a job like yours?
As a veterinarian, I have a bachelor’s degree, as well as a DVM – Doctor of Veterinary Medicine. However, there are many ways that you can be involved with marine mammals or ocean conservation – through a Master’s or PhD, if you’re more science-focused, or you can have a completely unrelated career, and get your fill through volunteering at a facility like TMMC. We even have a Youth Crew volunteer program for teenagers 15-18 years old (learn more at http://www.marinemammalcenter.org/Get-Involved/volunteer/youth-crew ). As far as experiences go, I would recommend doing as much as you can to get a variety of experiences, which will help you decide what is really right for you. I’ve worked with dogs and cats, horses and cattle, birds and seals, and each experience set me up for the next step in my career. 
What have you learned from working with these animals?
I’ve learned that in order to conserve energy while diving, some seals can lower their heart rate to 10 beats per minute, and right before they surface, their body speeds the rate back up to 120. I’ve learned that a sea otter, if left alone, will unscrew all of the screws on a drain – that were placed with an electric drill! – with its bare paws. And I’ve learned that a harbor seal, blind from cataracts, can find fish by sensing the water movement with its vibrissae (whiskers). Each one of our patients has given me great stories with which to share the knowledge I’ve learned. 
What is an Unusual Mortality Event? What is it like to attend one? Tell me about the most recent one you attended? 
If a group of marine mammals are sick, they may strand on the beach near one another. Unusual Mortality Events (UMEs) are declared when the number of sick or dying animals is larger than expected in that area or time frame. A panel of experts is then called to lead a response to care for the animals, and to try to figure out why they are dying. A recent UME was close to home – in 2013, more than 1500 starving California sea lion pups washed up on southern California beaches. Thanks to the UME response team, it was determined that the reason the pups were starving was because the fish their moms were feeding on had moved farther offshore – meaning they had to go farther to forage. This caused moms to either lack the milk they needed to nurse them, or abandon their pups completely. Caring for hundreds of sea lion pups at a time is exhausting – most need to eat 3-4 times a day, and they may need treatment for vomiting, diarrhea, or pneumonia. It was thanks to hard-working rehabilitation centers, like TMMC, all along the California coast, that we were able to save so many pups. 
What is the Marine Mammal Health Map? How do you contribute to it?
Think about all of the animals we’ve talked about – starving sea lions, entangled elephant seals, gunshot animals or animals with cancer. Each one of these animals provides a unique look at what is happening in the ocean at that location. All of the animals that come through TMMC have a record with all of their health information. Similarly, all of the stranding centers across the country have records on all of their animals. However, there is no centralized database to collect these data, or display them for all to see. The Marine Mammal Health Map will be that space – so that biologists, veterinarians, and members of the public will know what’s happening to marine mammals in their area. I’m working with scientists from around the country to develop the Health Map and ensure that all of our marine mammals are represented. You’ll have to come to the talk to learn more!
