    Hemigrapsus oregonensis

    Bay Shore Crab

    I have a nearly rectangular upper shell.

    I have visible fringes of "hair" on my legs.

    I feed mainly on seaweeds, especially green algae.

    I am common in salt marshes all along the northern Pacific coast of North America.

    Mya arenaria

    Softshell Clam

    My native home is the Atlantic Ocean, but I was introduced to San Francisco Bay by the 1870s and spread as far north as Alaska by the 1950s.

    I live buried in sand or mud.

    I have a hard shell and thick tube-like "siphons" that are used to bring in water, which I filter for food particles then expel.

    Many humans say I am delicious.

    Microtus californicus

    California Vole

    I live mainly in California.

    I am found in grassy fields, meadows, and around wetlands.

    I am active mainly during the day, but try to stay hidden from predators in runways I make through the grass and shallow underground tunnels.

    I eat green vegetation when I can, but lots of roots and seeds during the dry summer.

    Clevelandia ios

    Arrow Goby

    I live in the water along the Pacific coast from Canada to Mexico.

    To keep me safe from predators and drying out, I often live in burrows in mud or sand made by shrimps or worms.

    I am quite small, just around 4 to 6 cm long.

    I feed on tiny bits of algae and invertebrate animals, sometimes placing large food particles near crabs and waiting for them to shred them into pieces I can eat.
