Chironex fleckeri lives on a diet of prawns and small fish, as well as crabs and other pelagic invertebrates. [8] [11] Their only known predators are green sea turtles and leatherback turtles, whose thick skin is impenetrable to the cnidocytes of the jellyfish, among other pelagic predators. [9] [11]
The box jellyfish actively hunts its prey (small fish), rather than drifting as do true jellyfish. They are strong swimmers, capable of achieving speeds of up to 1.5 to 2 metres per second or about 4 knots (7.4 km/h; 4.6 mph).
Carybdea have a box-shaped bell with four tentacles and eye-like sensory structures. There are distinct physical markings that differentiate many species within the genus. While Carybdea use their venom to act as predators, they are also preyed on by turtles and various fish. They feed on plankton, invertebrates, fish, and some crustaceans.
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 ...
Cubozoa is a group commonly known as box jellyfish, that occur in tropical and warm temperate seas. They have cube-shaped, transparent medusae and are heavily-armed with venomous nematocysts. Cubozoans have planula larvae, which settle and develop into sessile polyps, which subsequently metamorphose into sexual medusae, [ 11 ] the oral end of ...
Box jellyfish have 24 eyes that are categorized into four morphological types. These four types are made up of two pigment cup eyes and two lens eyes that enhance the jellyfish’s ability to navigate their environment and detect prey or predators. [ 8 ]
The Irukandji jellyfish (/ ɪr ə ˈ k æ n dʒ i / irr-ə-KAN-jee) are any of several similar, extremely venomous species of rare box jellyfish. With a very small adult size of about a cubic centimetre (1 cm 3 or 0.061 in 3 ), they are both one of the smallest and one of the most venomous jellyfish in the world.
Its ecology is still relatively unknown, but it is presumed that it is a daylight predator [1] whose prey includes small crustaceans and fish. [2] Like other box jellyfish, Tamoya ohboya is highly venomous. [2]
