Cool New Creatures

From flashy fish to cunning crustaceans, there’s always something new to find at Birch Aquarium. Look for these creatures on your next visit! These are just a few of the new creatures to see.

Our new Cowfish lives in the Mangrove exhibit in the Hall of Fishes.

Guess Who MOOved In? 
Our new Cowfish is quickly becoming a staff and guest favorite. Cowfish are easily identified by their box-like shape, bright yellow color, and pointed horns above their eyes. They are found in sandy lagoons and shallow coral reefs throughout the Indo-Pacific. Find our Cowfish in the Mangrove exhibit in the Hall of Fishes.

A school of Pacific Mackerel and Croakers are the newest members of the Magdalena Bay exhibit.

Mackerel, Croakers, a Turtle, Oh My! 
There are a few hundred new friends schooling in the Magdalena Bay exhibit along with our Loggerhead Sea Turtle. These Pacific Mackerel and Croakers are a shining (and shimmering) example of the type of schooling fish that can be found off of Southern California and Baja. Mackerel and Croaker use this schooling behavior to avoid becoming a snack for ocean predators — safety in numbers!

Sand Crab? Mole Crab? No matter what you call them you can find these cool crustaceans in the Nursery in the Hall of Fishes.

We Are Really Digging Mole Crabs
Mole Crabs? Sand Crabs? No matter what you call them, most San Diegans — especially kids — are enamored by these burrowing crustaceans. Mole Crabs use their feather-like appendages to filter tiny food out of the water. You can find them buried in the sand along the water’s edge on sandy beaches like La Jolla Shores, and in the Hall of Fishes.

Cannonball Jellies are found seasonally in San Diego and you can find them now in the Hall of Fishes.

Cannonball Jellies are Making a Splash 
Cannonball Jellies are often seen in San Diego’s waters during the summer months, and are commonly found across temperate Pacific and Atlantic Oceans. The name “Cannonball” is fitting as they can grow to have a bell that is 10 inches in diameter! These rotund jellies are important food for sea turtles.
