Flower urchins have few predators. [17] They are known to be toxic to fish. One of the few organisms capable of consuming flower urchins with no apparent adverse effects is the predatory corallimorph Paracorynactis hoplites. However it is unknown if flower urchins are among its natural prey. [31]
They are known to possess medically significant venom to humans on their pedicellariae (tiny claw-like structures). They are sometimes collectively known as flower urchins , after the most widespread and most commonly encountered species in the genus, the flower urchin ( Toxopneustes pileolus ).
About 80 of the 600 unique species of sea urchins contain poisons, but they generally do not cause significant harm to humans. [5] However, an allergic reaction or large enough dose of the toxins (such as puncture by > 15-20 spines) may lead to systemic effects such as nausea, vomiting, paraesthesia, generalized weakness, and respiratory ...
Toxopneustes roseus is similar in appearance to the more widespread flower urchin, Toxopneustes pileolus. It can be distinguished by having a rigid "shell" ( test ) that is a solid pink, red, or purple in color, in contrast to the variegated coloration of the test of Toxopneustes pileolus .
They share more genetic material with humans than fruit flies do and can’t fly away — in short, an ideal lab animal for the developmental biologist. Scientists have been using sea urchins to ...
Diadema antillarum has a "shell," similar to most other sea urchins. What distinguishes the Diadema is the length of its spines. Most sea urchin spines are 1–3 cm, but the spines in this species are usually 10–12 cm in length, and can grow as long as 30 cm in very large individuals.
