California sea cucumbers are large squishy invertebrates that occupy the shallow ocean floor. As scavengers, they sift through the sand using tentacles which protrude from their mouth, looking for dead or decaying organic matter. Their mouths and anuses are on opposite ends of their body and they move using rows of tube feet that line the bottom of their body. Because their bodies are so soft, they are covered with spike like protuberances that they fill with surrounding ocean water to appear prickly and unappetizing. These body coverings are in fact soft and merely mimic the rough texture of other ocean invertebrates.
