![]() ![]() ![]() Breeding occurs in lower levels of rivers and mangrove channels. This species has also been documented from the Philippines, meaning the non-Australian records of C. To further confuse, the closely related and also dangerously venomous Chironex yamaguchii was first described from Japan in 2009. In Australia, it is known from the northern coasts from Exmouth to Agnes Water, but its full distribution outside Australia has not been properly identified. The medusa is pelagic and has been documented from coastal waters of Australia and New Guinea north to the Philippines and Vietnam.

They are attracted to light of different colors (white, red, orange, yellow, green and blue), but blue light seems to elicit a feeding behavior, as it slows down their pulsation rate and makes them stream out their tentacles. Some of these eyes seem capable of forming images, but whether they exhibit any object recognition or object tracking is debated it is also unknown how they process information from their sense of touch and eye-like light-detecting structures due to their lack of a central nervous system. fleckeri has four eye-clusters with 24 eyes. Box jellyfish are day hunters at night they are seen resting on the ocean floor. ![]() The tentacles are covered with a high concentration of stinging cells called cnidocytes, which are activated by pressure and a chemical trigger they react to proteinous chemicals. When the jellyfish are swimming, the tentacles contract so they are about 150 mm (5.9 in) long and about 5 mm (0.20 in) in diameter when they are hunting, the tentacles are thinner and extend to about 3 m (9.8 ft) long. ![]()
