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).
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 .
The flower urchin is a dangerous, potentially lethally venomous species. The spines, long and sharp in some species, protect the urchin from predators. Some tropical sea urchins like Diadematidae, Echinothuriidae and Toxopneustidae have venomous spines. Other creatures also make use of these defences; crabs, shrimps and other organisms shelter ...
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 ...
How humans are scaring fish off finding a mate. Jack Guy, CNN. August 7, 2024 at 5:49 AM ... Humans have responded to this behavior by targeting these events in order to catch more fish, which ...
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 ...
