A bizarre gelatinous creature that resembles a half-peeled banana was spotted by researchers in the Pacific Ocean. The creature, known as a gummy squirrel (Psychropotes longicauda), is actually a sea cucumber and was around 2 feet (60 cm) long.

This is Psychropotes longicauda, one of the sea cucumber species commonly observed at MBARI’s research site Station M. These sea cucumbers grow from 75 to 150 millimeters (three to six inches) long and feed on detritus that drifts down from surface waters. This group of sea cucumbers is found worldwide in very deep waters ranging from 2,000 to 6,000 meters (6,560 to 19,685 feet). Although they have the ability to swim, researchers aren’t exactly sure what the large fin is used for in this species.
Long-term studies at Station M have revealed that this species of sea cucumber seems to prefer eating older detritus that has been partially decomposed by bacteria. The observations made over the last three decades of research at Station M provide a glimpse into the dynamics of life on the ocean floor.
Cool Facts- Pineapple sea cucumbers are the kings of the sandy bottom. Active mostly during the day, these sea cucumbers wiggle their way across the ocean floor using numerous tube-like feet. They sift through sand with their large mouth for algae, helping to recycle nutrients like a true bottom feeder. The pineapple sea star plays host to hundreds of parasites, up to 800 unique species at one time, some never known to science until the discovery of this cucumber. Despite their numerous parasites, the pineapple sea cucumber is a delicacy in China and has resulted in their sharp population decline.
Rating- 11/10 (Has ananas in its scientific name, I applaud scientists.)
