Conoce al cerdo de mar
De puntillas sobre el fondo marino profundo, un cerdo de mar busca su comida. Los tentáculos alrededor de su boca exploran el lodo en busca de delicias: trozos de animales muertos, excremento y mucosidad.
How big are sea pigs?
Compared to a human, sea pigs aren't large. Most measure between 1.5 and 6 inches (4–15 centimeters) long.
Not your normal cucumber
The sea pig may get its name from its pink-colored body and love of the muddy seafloor, but it's actually a type of sea cucumber. The odd-looking, but surprisingly adorable creature has tube feet on its underbelly, back, and surrounding its mouth.
Snuffling along the seafloor
The sea pig spends its days snuffling through the muddy sediments on the seafloor, eating bits of dead algae and animals that have fallen from the surface. When something big, like a whale fall, sinks to the seafloor, huge herds of sea pigs gather nearby to feast on the rich organic sediments from the decaying carcass.

Deep sea babysitters
Sea pigs might be deep sea babysitters. Our research partners at the Monterey Bay Aquarium Research Institute (MBARI) frequently see juvenile lithodid crabs (Neolithodes diomedeae) climbing on or hiding under sea pigs—possibly as a way for the young crabs to protect themselves from predators.

Nobody knows why sea pigs are often spotted with juvenile king crabs clinging to them, like this pair photographed at almost 1,300 meters (4,200 feet) beneath the surface. One possibility is that the crabs are seeking protection from potential predators.
