Chironex fleckeri is the largest of the cubozoans (collectively called box jellyfish), many of which may carry similarly toxic venom. Its bell usually reaches about 16 cm (6.3 in) in diameter but can grow up to 35 cm (14 in). [8] From each of the four corners of the bell trails a cluster of 15 tentacles. [4]
Box jellyfish species Chiropsalmus quadrumanus contradicts the belief that Cubozoans are semelparous. Cubozoans usually have an annual life cycle. Box jellyfish reach sexual maturity when their bell diameter reaches 5 millimeters. [34] Chirodropida reproduces by external fertilization.
M. virulenta is one of the largest species of box jellyfish, with tentacle lengths of about three metres at maximum extension. The maximum bell height observed in M. virulenta can range up to 250 mm and the bell width can range up to 200 mm. [3] The bell of M. virulenta is rectangle-shaped and covered with nematocyst warts.
Chiropsalmus quadrumanus, commonly known as the four-handed box jellyfish, ... (9.8 to 13.1 ft) long. Halfway up the inside of the bell is the velarium, a horizontal ...
Copula is a monotypic genus of box jellyfish in the family Tripedaliidae of the phylum Cnidaria. The only species in the genus is Copula sivickisi, a very small gelatinous, bell-shaped jellyfish with four tentacles that is active only at night. It is unusual among box jellyfish in having a mating ritual and internal fertilization.
Tripedalia are relatively small in size, ranging from 11 to 15 mm. Both species have a cuboid bell and are transparent with a yellowish to brownish color. Their bells contain nematocyst warts that are mainly around the outline of T. cystophora and are thinly spread throughout T. binata.
The underside of the bell is partially constricted by a velarium, [2] a horizontal ring of tissue, [3] and in the centre is a manubrium, a tube-like structure which hangs down with the mouth at its tip. [4] This box jellyfish is a translucent yellowish-brown colour. [2]
Carybdea marsupialis is a small transparent jellyfish with a box-shaped bell [2] about 3 cm (1 in) across, at the four lower corners of which are four elongated tentacles up to 30 cm (12 in) long. The bell has a number of small white or yellowish warts with stinging cells, and near the margin, equidistant from the tentacles, are four rhopalia ...
