California is close to having two new state symbols — a famous slug and an expensive crab. UC Santa Cruz students and alums have something to celebrate. Their mascot, the banana slug, is about to become the official state slug. You can find the slugs in coastal lowlands, where they have a symbiotic relationship with redwood trees. Banana slugs cut down their competition by eating young shoots of other trees. Redwoods reciprocate by creating a cooler climate on the forest floor. But the slug isn’t the only new official state symbol. California will also have a state crustacean — the Dungeness crab.
