How do crustaceans protect themselves?
Crustaceans are a diverse group of mostly aquatic animals found all over the globe, from shallow seas, to tide pools, to the abyssal depths of the deep oceans. Crustaceans, such as crabs and shrimp, are relatively low on the food chain and are often preyed upon by fish, sea mammals, mollusks (including octopi), and humans. As a result of this, crustaceans have developed several ways to protect themselves from potential predators.
