Toxopneustes maculatus is a rare species of sea urchin found in the Indo-West Pacific. [2]
Toxopneustes maculatus is one of the four species in the genus Toxopneustes . It belongs to the family Toxopneustidae in the order Camarodonta. It was originally described as Echinus maculatus by the French naturalist Jean-Baptiste Lamarck in 1816, in the second book of his Histoire naturelle des animaux sans vertèbres series. [1] The generic name Toxopneustes literally means "poison breath", derived from Greek τοξικόν [φάρμακον] (toksikón [phármakon], "arrow [poison]") and πνευστος (pneustos, "breath"). The specific name maculatus means "spotted" in Latin.
The appearance of living specimens is unknown, but like other flower urchins, it probably has prominent pedicellariae. It is only known from empty "shells" (tests). The tests have a distinctive color pattern with a large bright purple blotch around the entirety of the bottom surface as well as a bright blue-violet band around the middle. [3]
Toxopneustes maculatus has a range probably as large as that of the more common Toxopneustes pileolus , but it is exceedingly rare. It is known only from a few specimens recovered from Réunion, Christmas Island, unspecified areas of the Indian Ocean, and the Palmyra Atoll. [3] [4]
Lytechinus variegatus, commonly called the green sea urchin or the variegated sea urchin, is a species of sea urchin that can be found in the warm waters of the western Atlantic Ocean and Caribbean Sea.
Coelopleurus is an extant genus of echinoids with fossil records dating back to the Eocene, with remains found in Europe and North America.
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. It inhabits coral reefs, seagrass beds, and rocky or sandy environments at depths of up to 90 m (295 ft). It feeds on algae, bryozoans, and organic detritus.

Toxopneustes is a genus of sea urchins from the tropical Indo-Pacific. It contains four species. They are known to possess medically significant venom to humans on their pedicellariae. They are sometimes collectively known as flower urchins, after the most widespread and most commonly encountered species in the genus, the flower urchin.
Argopatagus planus is a species of sea urchin of the family Macropneustidae. Their armour is covered with spines. It is placed in the genus Argopatagus and lives in the sea. Argopatagus planus was first scientifically described in 1907 by Alexander Emanuel Agassiz and Hubert Lyman Clark, American scientists.
Eucidaris is a genus of cidaroid sea urchins known as slate pencil urchins. They are characterised by a moderately thick test, a usually monocyclic apical disc, perforate and non-crenulate tubercles and nearly straight ambulacra with horizontal pore pairs. The primary spines are few and widely spaced, stout with blunt flat tips and beaded ornamentation and the secondary spines are short and apressed. They originated in the Miocene and extant members of the genus are found in the tropical Indo-Pacific Ocean, East Pacific, Atlantic Ocean and Caribbean Sea.
Eucidaris metularia, the ten-lined urchin, is a species of sea urchins in the family Cidaridae. It is found in shallow parts of the Indo-Pacific Ocean and is characterised by its sparse covering of banded, flat-tipped spines.
