The Sea Pig is a type of sea cucumber that 'walks' on the deepest ocean floor using hydraulically operated tube feet. The mouth is surrounded by a ring of feeding tentacles that sift through the mud and grab onto food. Whip-like papillae on the upper body are also modified tube feet; scientists believe these papillae may allow the sea pig to "smell" its way to food. About 4-6 inches long, Scotoplanes sp. are Echinoderms, related to starfish and sea urchins. https://www.oceannetworks.ca/ Follow ONC on social media: Twitter: https://twitter.com/ocean_networks Instagram: https://instagram.com/ocean_networks Facebook: https://facebook.com/OceanNetworksCanada
