Diadema setosum is a species of long-spined sea urchin belonging to the family Diadematidae. It is a typical sea urchin, with extremely long, hollow spines that are mildly venomous. D. setosum differs from other Diadema with five, characteristic white dots that can be found on its body. The species can be found throughout the Indo-Pacific region, from Australia and Africa to Japan and the Red Sea. Despite being capable of causing painful stings when stepped upon, the urchin is only slightly venomous and does not pose a serious threat to humans.

Agassizia is a genus of sea urchin of the family Prenasteridae. The species was first scientifically described in 1869 by Achille Valenciennes.
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.
Echinometra mathaei, the burrowing urchin, is a species of sea urchin in the family Echinometridae. It occurs in shallow waters in the Indo-Pacific region. The type locality is Mauritius.
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.
Agassizia excentrica is a species of sea urchin of the family Prenasteridae. The species was first scientifically described in 1869 by Alexander Agassiz.
Amblypneustes elevatus is a species of sea urchin of the family Temnopleuridae. Their armour is covered with spines. It came from the genus Amblypneustes and lives in the sea.
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.
Echinometra lucunter, the rock boring urchin, is a species of sea urchin in the family Echinometridae. It is found in very shallow parts of the western Atlantic Ocean and the Caribbean Sea.
Echinometra viridis, the reef urchin, is a species of sea urchin in the family Echinometridae. It is found on reefs in very shallow parts of the western Atlantic Ocean and the Caribbean Sea.
Arbacia spatuligera is a species of sea urchin of the family Arbaciidae. Its armour is covered with spines. A. lixula was first scientifically described in 1846 by Valenciennes.
Astriclypeus mannii is a species of sea urchin of the family Astriclypeidae. Their armour is covered with spines. It is placed in the genus Astriclypeus and lives in the sea. Astriclypeus mannii was first scientifically described in 1867 by Verrill.
Breynia elegans is a species of sea urchins of the Family Loveniidae. Their armour is covered with spines. Breynia elegans was first scientifically described in 1948 by Ole Theodor Jensen Mortensen.
Centrostephanus nitidus is a species of sea urchin of the family Diadematidae. Their armour is covered with spines. Centrostephanus nitidus was first scientifically described in 1927 by Koehler.
Chondrocidaris brevispina, the raspberry sea urchin, is a species of sea urchins of the family Cidaridae. Their armour is covered with short, conical spines.
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.
Athanas areteformis is a species of small alpheid shrimp from the Indo-West Pacific.
Araeosoma is a genus of deep-sea sea urchins in the family Echinothuriidae.
Echinometra oblonga, also called the oblong urchin or 'ina 'ele 'ele in Hawaiian, is a very common rock boring urchin on shallow rocky shores of the tropical Indo-Pacific and Southern Africa.
