Risso’s Dolphins at Whale and Wildlife Adventure

Risso’s Dolphins were spotted last week at Whale and Wildlife Adventure! Preferring deep open waters, these amazing animals can be found around the world, from the Pacific, Indian, and Atlantic Oceans to more inland seas. We don’t usually see Risso’s in these waters, and it was a treat to watch them in the wild.

A Risso’s Dolphin’s teeth are cone-shaped and are located on the lower jaws. Their upper jaws are toothless.


The skin of a Risso’s is gray when it is born and lightens as it ages. The skin becomes scarred from encounters with squid, a favorite prey, and other Risso’s.

At Whale and Wildlife Adventures with Birch Aquarium and Flagship Cruises & Events, head out into the mighty Pacific and witness humpback, fin, and even blue whales–the largest animals to ever live on Earth–at their summer feeding grounds. Learn from Aquarium naturalists as they lead the search for whales, dolphins, sea lions, sharks, and seabirds on this unforgettable adventure!

Whale and Wildlife Adventures run through September, on Saturdays, Sundays, and select holidays. Visit aquarium.ucsd.edu for more information.
