Calappidae Harlequin Shrimp Feb 19, 2015 #4 It's actually an Echinometra lucunter, a species of rock urchin. They are not poisonous, nor are they venomous. Firmly grasping this species shouldn't puncture any skin. Last edited: Feb 20, 2015

Calappidae Harlequin Shrimp Feb 20, 2015 #7 Nah, these species are very reef safe. Their spines are too frail to push rock. (they'll snap off first)
