Most sea cucumbers live a sedentary life on the bottom of the ocean, eating sediment or detritus that rains down from above. But some sea cucumbers like this Benthothuria sp. leave the life of eating and pooping on the seafloor, temporarily swimming. They may do this as a defense behavior, or to find a mate. #seacucumber #monterey #ocean #deepocean #deepsea #sealife #marinebiology #fyp
