The subclass Euechinoidea includes almost all living species of sea urchin, and fossil forms going back as far as the Triassic.
The Aspidodiadematidae are a family of sea urchins.
Astropyga radiata, the red urchin, fire urchin, false fire urchin or blue-spotted urchin, is a species of sea urchin in the family Diadematidae. It is a large species with long spines and is found in the tropical Indo-Pacific region. It was first described in 1778 by the German naturalist Nathaniel Gottfried Leske.
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms.
The Echinacea are a superorder of sea urchins. They are distinguished by the presence of a rigid test, with ten buccal plates around the mouth, and solid spines. Unlike some other sea urchins, they also possess gills. The group is a large one, with species found worldwide.
The Echinothurioida are an order of sea urchins in the class Echinoidea. Echinothurioids are distinguished from other sea urchins by the combination of a flexible test and hollow spines. The membrane around the mouth contains only simple plates, in contrast to the more complex mouth parts of their close relatives, the Diadematoida. They are nearly all deepsea dwellers.
The Camarodonta are an order of globular sea urchins in the class Echinoidea. The fossil record shows that camarodonts have been in existence since the Lower Cretaceous.
Zebrida is a small genus of distinctive striped crabs, known as zebra crabs, that live in association with sea urchins in the Indo-Pacific.
Amphipneustes davidi is a species of sea urchin of the family Temnopleuridae. Their armour is covered with spines. It is placed in the genus Amphipneustes and lives in the sea. Amphipneustes davidi was first scientifically described in 2010 by Madon-Senez.
Asthenosoma varium is a sea urchin. Growing up to 25 cm (10 in) in diameter, it lives on sand and rubble sea bottoms in the Indo-Pacific, from the Red Sea to Australia and Southern Japan. Its venom tipped spines, with distinctive globular swellings below the tip, can inflict a painful sting if handled; the pain lasts as long as several hours. This capacity, perhaps coupled with its reddish-brown colour, has given it the common name fire urchin; other commonly used names are Pacific fire urchin, elusive sea urchin, variable fire urchin, and electric sea urchin.
Araeosoma thetidis is a species of sea urchin of the family Echinothuriidae. This species can be found in deep sea off Australia and New Zealand. A. thetidis was first scientifically described in 1909 by Hubert Lyman Clark.
Echinometra is a genus of sea urchins in the family Echinometridae.
Asterechinus elegans is a species of sea urchin of the family Trigonocidaridae. Their armour is covered with spines. It is placed in the genus Asterechinus and lives in the sea. Asterechinus elegans was first scientifically described in 1942 by Ole Theodor Jensen Mortensen.
Asthenosoma dilatatum is a species of sea urchin of the family Echinothuriidae. Their armour is covered with spines. It is placed in the genus Asthenosoma and lives in the sea. Asthenosoma dilatatum was first scientifically described in 1934 by Ole Theodor Jensen Mortensen.
Asthenosoma intermedium is a species of sea urchin of the family Echinothuriidae. Their armour is covered with spines. It is placed in the genus Asthenosoma and lives in the sea. Asthenosoma intermedium was first scientifically described in 1938 by Hubert Lyman Clark.
Asthenosoma marisrubis is a species of sea urchin of the family Echinothuriidae. Their armour is covered with spines. It is placed in the genus Asthenosoma and lives in the sea. Asthenosoma marisrubis was first scientifically described in 1998 by Weinberg & de Ridder.
The Echinothuriidae are a family of sea urchins in the order Echinothurioida. Due to their soft skeletons, most are called "leather urchins", but species in the genus Asthenosoma are also known as "fire urchins" due to their bright colors and painful, venomous sting.
Asthenosoma is a genus of sea urchins in the family Echinothuriidae. Their spines are covered with harmful venom capsules.
