Bay Shore Crab
The square-shaped Bay Shore crab is a common intertidal resident. It lives in the quiet, brackish waters of San Elijo Lagoon, coming out to feed mainly at night. Its body is usually yellowish or grayish-green, though it may also be dark reddish-brown with green spots. Its four posterior legs are conspicuously hairy. It grows to just over an inch long.
This tough little crab can tolerate lower salinities and murkier waters than most other shore crabs.
What’s for Lunch:
Algae and diatoms, unless it can get meat
