Chris Mah @echinoblog.bsky.social · 25/03/2025An interesting urchin from #Okeanos the other day 4200m in the Hawaiian Islands, kinda echinothuriid-like but did not spot the characteristic "hooves" on the spines.. but it left a great track! #echinoday 25110
Chris Mah @echinoblog.bsky.social · 26/03/2025Informed by my colleague Kiril Mininn at the Shirshov Institute in Russia that this is a holasteroid urchin, a sort of "living fossil".. not a common beast. Conceivably undescribed but details from image don't tell the full story.. 040
