While exploring Ahyi Seamount, the team spotted this Diadema setosum #urchin nestled in an algae bed around 74 meters deep. These #marineinvertebrates are known for their extremely long, black, hollow spines interspersed with stinging, pincher-like pedicellariae.

A baby long-spined sea urchin (Diadema setosum) hiding in the seaweed on the rocky shore✹
Even knowing it’s venomous, it’s hard to avoid something this tiny.
Always wear proper shoes and gloves when exploring tide pools!

1 more Crustacean (subphylum of Arthropoda), Giant Barnacle (Tetraclita squamosa). Then the Sea Urchin Class of Phylum Echinoderma. My fave is Slate Pencil (Heterocentrotus mamillatus) & below is Rock-boring (Echinometra mathaei) & Needle (Black longspine) (Diadema setosum) 10/24
