Are pedicellariae venomous?
Sea urchins have tubular feet called pedicellariae, which enable movement. In one genus of sea urchin — the flower sea urchin — some of the pedicellariae have evolved into toxic claws. In these animals, the spines are short and harmless, but these toxic claws can inflict an envenomation.
