Seapen - Retriever Seamount

Description:

Description: English: Close-up of a sea pen colony at 2023 meters depth on Retriever Seamount. Sea pens are octocorals and the characteristic eight pinnate tentacles are plainly visible in this image. The dark line running down below the tentacles of each polyp is the pharynx, connecting the mouth to the bag-like digestive cavity. A mysid shrimp (“possum shrimp”) is swimming by the colony.
