"The California Endangered Species Act was designed to protect "native species or subspecies of a bird, mammal, fish, amphibian, reptile, or plant."
Notably, invertebrates are absent from the list of protected species.
But in a lucky loophole for insects, mollusks, and other spineless creatures falling under the umbrella term "invertebrate," the act itself defines a "fish" as "a wild fish, mollusk, crustacean, invertebrate, amphibian, or part, spawn, or ovum of any of those animals.""
