They’re Born This Way – Adaptations for an Aquatic Environment

Beluga whales often swim in shallow waters at depths that barely cover their bodies. In general they are not thought of as deep diving marine mammals, but they are capable of making deep dives and staying under water for as long as 15 minutes. Why are they able to do that?

Like other marine mammals, beluga whales possess a number of physiological adaptations that we humans do not have that allow them to dive to deep depths and stay under water for longer periods of time than we can.

During dives beluga whales have a slower heart rate. Also, while diving, blood is shunted away from tissues in their bodies that can tolerate low levels of oxygen towards the heart, lungs and brain where more oxygen is needed. Beluga whales possess more oxygen in their blood than most other animals. And, last, but not least, the muscle of belugas has a high content of an oxygen-binding protein called myoglobin. This protein stores oxygen and prevents muscle oxygen deficiency.

All of these adaptations enable the beluga whale to conserve oxygen while under water and do something we humans can only do through artificial means.

Life of a Marine Mammal Caregiver

The most important part of a marine mammal caregiver’s job is keeping routine records of all of the animals.

“We have sheets for each of the animals. We’ll write down what they did that day, their behavior that day and how they are interacting with the other animals they are living with,” said Dan Macdonald, marine mammal caregiver.

These records are used to communicate with other caregivers and veterinary staff, so they can stay up to date with each animal.

The bond between a caregiver and marine mammal is strong. The Marineland caregivers feel connected with the animals and love getting to know the individual personalities.

Do You Know How Playful Walruses Are?

Dan Macdonald, a marine mammal caregiver at Marineland explains, “A lot of the behind the scene care for walruses is play.”

Walruses are social and love to play together. They have even more fun if toys are incorporated. Now, what toys does a walrus like? Balls, huge logs and icebergs are the current favourites!

The walruses have their own community and can be selective about whom they want to spend time with. For example, Dan Macdonald explains, “Sonja really likes to live and be with Buttercup. So, when we get a chance to, we make sure they get to spend as much time as possible with each other.”

Now isn’t that cute? Check out the video here:

Getting to Know Kiska

Kiska gets a lot of attention from her marine mammal caregiver, Tali. Kiska gets between one to four sessions per hour with Tali, or one of her other marine mammal caregivers.

Tali explains that Kiska is not very interested in high-energy behaviours, like jumps. But, she loves to be rubbed with hands or brushes!

What’s for Breakfast?

Good morning!

We all know the importance of a well-balanced breakfast. You might have some cereal or bacon and eggs, washed down with a cup of coffee or orange juice. But, not Marineland’s animals! They also have a well-balanced breakfast, but less traditional items are on their menu.

The Marineland staff arrives bright and early to check all the animals, then, it’s time to serve breakfast! The staff takes out 2,000 pounds of fish to thaw. That’s a lot of fish! You can pick your jaw up off the floor, though! This isn’t all eaten at breakfast. The staff thaws the fish to feed to the marine mammals throughout the day.

We like to keep our animals healthy! Which is why we give them vitamins. And how do you get the animals to take their vitamins? Simple, you put the vitamins into the fish and then feed the fish to the marine mammals!

You might be wondering what the land animals at Marineland are fed for breakfast.
Each day, about 110 bales of hay and 454 kg (1,000 lbs) of grain such as corn, barley and oats, along with a vitamin supplement, are given to the deer, elk and bison.

Now, when you make your way around the park you will know what happens before the park opens! There is a lot of morning preparation at Marineland to keep our animals happy and healthy.

Marineland’s water system provides suitable environment for all marine mammals


Marineland ensures that its marine mammals are well taken care of and healthy. Over many years, we have made significant financial investments to develop and maintain a sufficient water management system to provide an appropriate environment for all marine mammals under our care.

A water treatment analysis report conducted by Stantec, an independent company, was released in 2013. It reveals that Marineland maintains best practices and conducts on-going research for development. Based on the assessment, it was found that the systems are suitable for maintaining water quality parameters for the species and number of marine mammals under human care. This assessment coupled with further research of relevant literature shows that Marineland’s systems meet modern standards of performance requirements.

Marineland is the most thoroughly inspected facility of its kind in the world


Over the last two years, Marineland has been the most thoroughly inspected facility of its kind in the world. The conclusion of all of these inspections – all of them – is that the marine mammals at Marineland are well taken care of and healthy, the facilities are excellent and there is no evidence of animal abuse.

These inspections included a complete independent review by two expert veterinarians on behalf of the Ontario Society for the Prevention of Cruelty to Animals (OSPCA) and multiple unannounced and scheduled inspections by the OSPCA Zoo Inspection team.

The care and treatment of marine mammals is a topic which attracts emotional responses – which Marineland understands. However, often times these emotional responses are not based on factual evidence. Marineland’s care and treatment of marine mammals is based on factual evidence and advice of scientific experts and veterinarians.

We are guided by these experts regarding the health and psychological well-being of our marine mammals. With confidence, we know that Marineland’s marine mammals are healthy and well treated.

What’s On The Menu?

Well, anything from herring to hay. Marineland provides wholesome, nutritious and palatable foods to all of our animals under the expert direction of our veterinary staff.

All of our marine mammals are fed restaurant quality herring, capelin and squid. In fact, you could take some home, cook it up and have it for dinner.

fishOur black bears receive a balanced diet of fish, fresh fruits, meats and vegetables. Yum!

Our deer, bison and elk dine only on hay that is of top quality. How much hay? Would you believe 110 bales per day?

For members of our deer family, hay is fed in conjunction with grains such as oats, corn and barley.
