Coastal trawling is a threat to Metacrinus rotundus as it lives at relatively shallow depths.
-
Metacrinus rotundus is a marine animal with a fan-like crown of arms supported by a tether-like stalk. It uses the arms, which are covered in rows of feather-like appendages (pinnules), to trap food such as plankton.
