Crown jellyfishes are the six families of true jellyfish that belong to the order Coronatae. They are distinguished from other jellyfish by the presence of a deep groove running around the umbrella, giving them the crown shape from which they take their name. Many of the species in the order inhabit deep sea environments.
Nausithoidae is a family of jellyfish.
Phyllorhiza punctata is a species of jellyfish, also known as the floating bell, Australian spotted jellyfish, brown jellyfish or the white-spotted jellyfish. It is native to the western Pacific from Australia to Japan, but has been introduced widely elsewhere. It feeds primarily on zooplankton. P. punctata generally can reach up to 50 centimetres (20 in) in bell diameter, but in October 2007, one 74 cm (29 in) wide, perhaps the largest ever recorded, was found on Sunset Beach, North Carolina.
Nausithoe aurea, also known as the Nausithoe maculata, is a species of crown jellyfish found off the southeastern coast of Brazil. The central disc has been measured to be 10.5 mm. N. aurea is transparent with yellow and brown spots located around the gonads. N. aurea can reproduce either asexually by strobilation or sexually. Either ephyrae or planuloids may be produced by strobilation; only ephyrae can produce the medusal form. Strobilation can be induced to occur when food is abundant. In polyps, a large availability of food leads to strobilation if it is not regulated. N. aurea species usually take more than 20 weeks to begin the differentiation and development of reproductive organs.
Nausithoe is a genus of jellyfishes belonging to the family Nausithoidae.
Nausithoe challengeri is a species of crown jellyfish in the family Nausithoidae. Adult medusa are believed to be up to 12 millimeters in diameter, and the specimen has long and thin tentacles.
Nausithoe atlantica is a species of crown jellyfish in the family Nausithoidae. They have only been encountered ~38 times by humans since records began, and inhabit the deep sea.
Nausithoe clausi is a species of crown jellyfish in the family Nausithoidae. The species has been observed in the Western Central Pacific, and are ~0.9 centimeters wide.
Nausithoe hagenbeckii is a species of crown jellyfish in the family Nausithoidae. Medusa of the species are estimated to be ~5 millimeters in diameter. Despite being a marine jellyfish, this species has yet to be found in the wild: the type specimen was collected from a tropical aquarium at Hagenbeck Zoo in Hamburg, Germany.
Nausithoe eumedusoides is a species of crown jellyfish in the family Nausithoidae. They have been observed as inhabiting the Mediterranean.
Nausithoe globifera is a species of crown jellyfish in the family Nausithoidae. The species is ~22 millimeters in diameter, 10 millimeters of which is composed of the central disc.
Nausithoe marginata is a species of crown jellyfish in the family Nausithoidae. The species has only been observed a handful of times, and may be extinct.
Nausithoe limpida is a species of crown jellyfish in the family Nausithoidae. An adult medusae is ~6 millimeters in diameter, and the species is possibly extinct.
Nausithoe rubra is a species of crown jellyfish in the family Nausithoidae. Adult medusa are believed to grow up to ~15 millimeters in size, and the species may be distributed worldwide. Species is confirmed to be in the East Atlantic, but may also reside in other oceans.
Nausithoe racemosa is a species of crown jellyfish in the family Nausithoidae. They are found in the Marshall Islands, and are poisonous.
Nausithoe simplex is a species of crown jellyfish in the family Nausithoidae. The species is found in the Indian Ocean, and are gonochoric.
Nausithoe sorbei is a species of crown jellyfish in the family Nausithoidae. Ephyrae of the species are believed to be 4.7–5.0 millimeters in diameter.
Nausithoe striata is a species of crown jellyfish in the family Nausithoidae. This species can be found in the Davis Sea.
Nausithoe thieli is a species of crown jellyfish in the family Nausithoidae. The species can be found in the Mediterranean Sea and Western Indian Ocean.
Nausithoe werneri is a species of crown jellyfish in the family Nausithoidae. They are concentrated off of the Brazilian coast.
