The box jellyfish (Cubozoa) or sea wasp uses its tentacles to stun or kill prey. The
tentacles contain venom which is extremely painful to humans and is one of the most
deadly in the world.
Box jellies are found in tropical Australian waters and the Indo-Pacific. They have 15
tentacles trailing from each corner of their bell and each tentacle has thousands of
stinging cells running through it. They propel through the water and can move quicker
than most jellyfish.
Box jellies have no brain, heart or skeleton. They have clusters of eyes, similar to our own
on each side of their bell. Each eye has a retina, iris, cornea and lens. Box jellyfish are pale
blue in colour and almost transparent which makes them difficult to see. They hunt
during the day and rest on the ocean floor at night. They feed on small fish and
crustaceans.
