However, the thumbnail-sized Irukandji is a box jellyfish, and lethal despite its small size. There are about 15 tentacles on each corner. There are about 15 tentacles on each corner. Each tentacle has about 500,000 cnidocytes , containing nematocysts , a harpoon-shaped microscopic mechanism that injects venom into the victim. [ 20 ]
Chiropsalmus quadrumanus is a cube-shaped, colourless, transparent jellyfish with a diameter of about 14 centimetres (5.5 in) and height a little less than this. The body is composed of a gelatinous material and the top edges are rounded while the top surface is flat.
Chirodectes is a very rare, monospecific genus of box jellyfish in the family Chirodropidae. The first and only scientifically studied specimen was captured from the outer edge of the Great Barrier Reef – about 43 km (27 mi) off the coast of northeast Queensland – on 2 May 1997. [2]
Box jellyfish swim by expanding and contracting their bells vigorously. [6] During the day Tripedalia cystophora is mostly to be found within 20 cm (8 in) of the surface, in sunlit positions among the prop roots of mangroves. These warm sunlit areas are where its main food item, the copepod Dioithona oculata, are to be found during the day. [5]

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 ]
Carukiidae is a family of box jellyfish within the Cubozoa class. [1] Carukiidae can be easily classified by their lack of cirri clumps inside the cubozoan stomach, as well as the size and the placement of their nematocysts.
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 ...
