#diadema-setosum
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!

Erizo Diadema (Diadema setosum), no evaluado (?).

Mya Breitbart, faculty at the Univ of South Florida using genomics to study marine critters from viruses through charismatic megafauna! Current projects: fish egg DNA barcoding, sea urchin disease, harmful algal blooms, seagrass viruses, marine phage, water quality. Passionate about outreach #USFCMS

Third in our Hong Kong Biodiversity Genomics Consortium series is of a spiny echinoderm algal and coral feeder widely distributed in the Indo-Pacific.

Technically #InverteFest is over but had to share this close-up glamor shot of Diadema setosum!

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
