Toxopneustes pileolus, commonly known as the flower urchin, is a widespread and commonly encountered species of sea urchin from the Indo-West Pacific.It is considered highly dangerous, as it is capable of delivering extremely painful and medically significant stings when touched.
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 ...
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 ...
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 .
Humans have responded to this behavior by targeting these events in order to catch more fish, which have started to engage less in courting behavior out of fear.
[1] 60% of all evaluated fish species are listed as least concern. The IUCN also lists 37 fish subspecies as least concern. Of the subpopulations of fishes evaluated by the IUCN, 44 species subpopulations have been assessed as least concern. This is a complete list of least concern fish species and subspecies evaluated by the IUCN.
