Sea pig

This deep-ocean sea cucumber, Scotoplanes globosa, is sometimes called a "sea pig" because its resemblance to terrestrial pigs. Like many sea cucumbers, Scotoplanes eat seafloor mud, along with small animals and microbes that live in the mud. Scotoplanes are typically 10-15 cm (four to six inches) long. They move slowly but gracefully on their stubby "legs," and sometimes form large "herds" that migrate across the muddy seafloor or congregate around sources of food. MBARI research suggests that populations of Scotoplanes can change dramatically over time depending on how much food sinks down to the deep seafloor.
