Celebrating Moms of ALL Species!

In celebration of Mother’s Day weekend, we’d like you to meet some spectacular animal moms!

Dolphins
Dolphin moms & calves immediately form a strong bond. They’ll synchronize their breathing and swim patterns for the baby’s first few weeks of life – to keep as close as possible. These dedicated moms will nurse their young for up to 10 years!

Veteran dolphin moms will also mentor less-experienced females in their colony by allowing them to babysit their young and practice for when they have their own babies.

Giant Pacific Octopuses
Female giant Pacific octopuses have one primary goal: to have one successful brood of eggs in her lifetime.

Females will lay about 200,000 eggs in their lair and defend them at any cost. During the seven months of caring for her eggs, the female octopus is often almost starved to death – she’d ingest a limb before leaving her post for food.

Strawberry Poison Arrow Frogs
After laying her eggs and watching them hatch, strawberry poison arrow frog moms will carry their tadpoles (one by one) from the rain forest floor up trees as high as 100 feet!

Then, she’ll find individual pools of water in the tree leaves for each of her tadpoles to grow, keeping them safe from predators.

Alligators
Alligator moms will go to great lengths to protect their young, including carrying alligator babies in their jaws for protection!

Practicing Routine Dolphin Exams

Today’s post comes from our Senior Marine Mammal Trainer, Kerry Martens! 

At the National Aquarium we believe in and practice excellence in animal care. As trainers, we work with the animals every day, practicing medical behaviors that allow us to take the best possible care of them.

Each morning the dolphins get a visual check. They have been trained to present to us different parts of their bodies so we can check their skin and get a good look at their overall body condition.

Next, we ask the animals to present their fluke. This is where the Veterinarians take a blood sample from. Routine blood samples are taken from our dolphins just like people get blood taken during check-ups with their doctors.

Besides looking at the overall body of the animal, there are a few other items we check out as well.

We check the dolphin’s teeth daily to make sure they are in good condition. Dolphins only have one set of pointy cone-shaped teeth for their entire lives!

We also check their breath, or blow. All of the animals are trained to forcefully exhale on cue. Lastly, once a week, the animals get weighed. They are trained to haul up and out of the water onto a flat scale. Most of our dolphins weigh between 300-400 pounds, but Nani is over 500!

Once we finish their daily visual check we want to make sure to reward the dolphins for their good behavior. As trainers it is extremely important that we have strong positive relationships with each of the animals. Play time is a great way to build that relationship!

The information gathered from the visual checks not only allows us to take the best care of our dolphins, but share information with other aquariums and researchers as well. For information on the National Aquarium’s many ongoing research projects, visit our Research page!
