About Our Dolphins

Taz dolphinCurrently, the Indianapolis Zoo has nine Atlantic bottlenose dolphins in its collection.  The adults range from 22-24 years old and weigh between 300- 500 pounds.  They each have unique personalities and physical characteristics that allow the marine mammal staff to tell them apart.  The adult male is Kimo, and the adult females are Nova, Ripley and China.  Four young dolphins have been born at the Zoo.  Nova’s female calf Kalei (KAH-LAY’) was born in November 2000.  China gave birth to another female later named Indy in August 2001, while Ripley produced a male, Jett, in February 2002.  An orphaned young male dolphin named Taz (right) came to the Zoo in 2011.  China gave birth to a male calf in summer 2012, and he has not yet been named.  
                                                                                   
dolphin dome-Elizabeth WallaceAll of the adult dolphins arrived in Indianapolis in 1988.  Since then, they have occupied the Dolphin Pavilion.  As built, the Pavilion stands 80 feet high at its maximum point and has 20 foot high skylights that stretch across the south side of the structure providing natural sunlight for the dolphins.  The facility holds 2.3 million gallons of carefully monitored and filtered saltwater, including one million gallons in the main performance pool.  This pool is 134 feet long, 56 feet wide and 27 feet deep.  It could hold more than 100 school buses or six average ranch style houses!  Three other pools hold the rest of the 1.3 million gallons of water, including two holding pools and a special medical pool that can be used if marine mammal staff or veterinary staff need to get “hands on” for routine or special medical procedures.

In 2005, the pavilion was redesigned to include a walk-through dolphin dome that is located in the center of the large performance pool.

The dolphins are cared for by a specially trained marine mammal staff headed by a curator of marine mammals.  This group of trainers also cares for the Zoo’s seals, sea lions, walruses and polar bears.  All of the Zoo's marine mammals are wonderful ambassadors for their wild counterparts and help us deliver important information about the Zoo's animal conservation mission.

The Indianapolis Zoo is accredited by the Association and Zoos and Aquariums (AZA) and is also accredited as a habitat botanical garden by the American Association of Museums (AAM).
