Dolphin Discovery

Experience the Dolphins Like Never Before

Dolphin Discovery, the Aquarium’s largest exhibit, first opened in 1990 and is home to our colony of eight Atlantic bottlenose dolphins!

The Animals

  • Six females: Nani, Jade, Spirit, Maya, Bayley and Chesapeake
  • Two males: Beau and Foster

Nani, our eldest dolphin at 42, is the mother to Beau and Spirit. Chesapeake was the first dolphin born at the National Aquarium and she is the mother to our youngest dolphin, Bayley. Maya is a half sister to Chesapeake (via dam or mother) as well as half sister to Spirit (via sire or father). Jade is the mother to Foster. All but one of our eight dolphins, Nani (41 years old), was born in an aquarium or zoological park. Nani, born in the wild more than 40 years ago, came to us from another aquarium that had to close.

This colony structure represents a complex social group for the dolphins and provides them with essential relationships. Bottlenose dolphins live in a matriarchal society due to the level of care that females provide to their young; the males live in separate social groups consisting of a few members that are called bachelor groups or alliances. Here are at the National Aquarium, we house our animals in what we call a nursery group which consists of all of our females ranging in age from 42 to 5 and our two males have formed a pair bonded group.

Exhibit Staff:

In Dolphin Discovery, we have 13 marine mammal trainers, a Director of Marine Mammal Training, Allison Ginsburg, and our Director of Animal Programs, Sue Hunter. Our marine mammals team is responsible for the everyday care of our dolphins including medical care, diet and nutrition, teaching and learning, research, and of course a lot of playtime.

We have staff who work in this exhibit full time and we also have team members who assist with the care of dolphins. Our veterinary team, led by Dr. Leigh Clayton, provides state-of-the-art medical care to each animal on a routine basis. It’s not unusual for guests to come in and see our vet team checking in.

A Typical Day:

A day in the Marine Mammal Department can start as early as 6:30 in the morning. It takes two full hours to sort and weigh out the 200 pounds of frozen fish that make up the dolphins’ diet. The dolphins get fed between 7-10 times per day, roughly every hour and half.

Sorting fish for the dolphins

Food is an essential part of their training through positive reinforcement. Our trainers work with the animals to create an enriching environment where they can learn new behaviors through play. Play is also a great way for us to build our relationship with the animals, which is key in all of the training that we do. We even help the dolphins learn certain behaviors to help us take care of them. For example, as part of regular their physicals, our veterinary team needs access to a dolphin’s fluke fin to take blood samples, so our trainers work with the dolphins through a series of play/reward sessions to obtain the desired fluke-raise behavior.

Our Staff

Our staff does some of this training work behind-the-scenes, but most are done during the day while guests are in the exhibit. There are many different types of sessions they participate in: some are focused on training these brand new behaviors, others are dedicated to husbandry and some consist entirely of playtime.

When we’re not working directly with the animals, we spend a majority of our time cleaning. This includes buckets, toys, the kitchen, all of our back-up areas and even the animals’ habitat. All trainers are SCUBA certified, which allows us to enter the water and scrub and vacuum each and every day.

In 2012, we changed over our Dolphin Discovery exhibit to allow our guests more access to the animals and our expert staff. Every day our dolphin exhibit is open for visitors to stop in as many times as they like for as long as they like during operating hours!
