When the jellyfish apparently became aware of the object in its tank, it was seemingly repelled by it and remained at the far edge of the tank. Finally, to see if the specimen could see colour, a single red pole was stood in the tank. This time, the jellyfish seemed aware of them and swam around them in a figure-eight. Then, similar black poles were placed into the tank. The creature appeared unable to see them and swam straight into them, thus knocking them over. Then, two white poles were lowered into the tank.

During a series of tests by marine biologists including Australian jellyfish expert Jamie Seymour, a single jellyfish was put in a tank. 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. Since it is virtually transparent, the creature is nearly impossible to see in its habitat, posing significant danger to swimmers. The pale blue bell has faint markings viewed from certain angles, it bears a somewhat eerie resemblance to a human head or skull. From each of the four corners of the bell trails a cluster of 15 tentacles.

Its bell grows to about the size of a basketball. Cnidocytes from Chironex fleckeri (400x magnification)Ĭhironex fleckeri is the largest of the cubozoans (collectively called box jellyfish), many of which may carry similarly toxic venom.
