A fish keeper has filmed a pair of multicoloured and poisonous flower hat jellies as they swam around their fishbowl.
Aquatic pet shop owner Kengo Shishioka, 40, from Japan, keeps a number of different toxic species in his tanks, including stonefish, lionfish and porcupine fish.
Kengo also breeds flower hat jellies, a species whose appearance resembles that of colourful jellyfish, but that actually belongs to a different class of marine animals.
Despite their stunning colours, flower hat jellies are poisonous and their sting can be extremely painful.
Kengo said: “Although they are not lethal, their sting hurts like a stab wound.
“They are stunning animals with very brief lives.”
