The shingle urchin (Colobocentrotus atratus) is a species of sea urchin found in the Indo-Pacific region, particularly in areas exposed to heavy wave action. It is uniquely adapted to its harsh intertidal environment through its strongly flattened, dome-shaped test and modified, scale-like spines. T...

The green sea urchin (Strongylocentrotus droebachiensis) is a cold-water marine echinoderm native to the coastal environments of the North Atlantic and Pacific Oceans. Characterized by its greenish test and protective spines, the species inhabits rocky subtidal zones where it grazes on algae and kel...

The flower urchin (Toxopneustes pileolus) is a species of sea urchin found in the Indo-Pacific region, particularly on coral reefs.

The collector urchin (Tripneustes gratilla) is a species of sea urchin distributed throughout the tropical Indo-Pacific, from the east coast of Africa to Hawaii. It is named for its habit of covering itself with seaweed, shells, pebbles, and other debris, which is believed to provide camouflage and...

Colobocentrotus mertensi is a sea urchin in the family Echinometridae found across the Indo-Pacific in wave-swept intertidal zones. Its morphology is highly modified for surviving violent surf: the test is flattened and its primary spines are short, broad, and overlapping, giving the animal a shingl...

The violet sea urchin (Sphaerechinus granularis) is a species of marine echinoderm found in the Mediterranean Sea and the eastern Atlantic Ocean. It is characterized by its distinctive, dense covering of short, typically violet or purple spines that often feature white tips. As a benthic grazer, it...

Strongylocentrotus nudus is a species of sea urchin in the family Strongylocentrotidae, native to the northwestern Pacific. It inhabits rocky coastal waters around parts of East Asia and feeds largely by grazing on algae and other material attached to the seabed. Like other edible sea urchins, it is...

Tetrapygus niger is a common black sea urchin species heavily distributed along the coasts of South America, where it plays a vital ecological role.

Parasalenia gratiosa is a tropical sea urchin and the only living member of its genus, commonly found grazing on Indo-Pacific coral reefs.

Salmacis dussumieri is a species of temnopleurid sea urchin from the Indo-Pacific region, named in honor of French voyager Jean-Jacques Dussumier.

Caenocentrotus gibbosus is a benthic sea urchin found in the Eastern Pacific Ocean, easily identified by its distinctly humped, or gibbose, skeletal test.

Allocentrotus fragilis is a species of sea urchin recognized for its delicate, fragile test, primarily found in the deep waters of the Pacific.

Amblypneustes elongatus is a species of temnopleurid sea urchin from the Indo-Pacific, distinguished by its elongated test shape.
