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 ...
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 ...
Although many people have a fear of mushroom poisoning by "toadstools", only a small number of the many macroscopic fruiting bodies commonly known as mushrooms and toadstools have proven fatal to humans. This list is not exhaustive and does not contain many fungi that, although not deadly, are still harmful.

Pedicellaria of Acanthaster planci Generalized pedicellaria of an (a) asteroid and (b) echinoid. A pedicellaria (pl.: pedicellariae) is a small wrench- or claw-shaped appendage with movable jaws, called valves, commonly found on echinoderms (phylum Echinodermata), particularly in sea stars (class Asteroidea) and sea urchins (class Echinoidea).
