Balloonfish in Lurking

A balloonfish has been added to our Lurking exhibit!

Balloonfish are mostly nocturnal animals, spending most of their nights feeding on a mixed diet of mollusks, sea urchins and crabs.

Did you know? Balloonfish have fused teeth, especially designed to crush through the shells of their prey!

Like other species of pufferfish, this species will fill with water and expand to nearly twice its size when threatened.

Wolf Eel in Kelp Forest

A small wolf eel has nicely settled into our Kelp Forest exhibit!

Did you know? Wolf eels are not actually eels, instead they part of the Anarhichadidae family of “wolf fishes.” These animals are fairly solitary and territorial - they have even been observed in the wild biting at sharks to keep them out of their caves!

This fish lives in the North Pacific from the Sea of Japan, to islands off the coast of Alaska, to the coast of southern California.

Be sure to check back every Friday to find out what’s happening!
