The box jellyfish gets its name as they are bell shaped or cubed shaped with four sides being very prominent, thus the name box jellyfish. They can be as long as 20 cm on each side of the block, and have around 15 tentacles on each corner. These tentacles are not actually triggered by any sort of touch, rather, this species of jellyfish stings because it senses a presence of a form of chemical on the outside of their prey.
A box jellyfish is extremely portable, with their bodies to propel themselves forward at speeds up to 4 knots. These kinds of jellyfish travel towards the beaches in the calmer weather, and settle around the mouths of the two creeks and rivers after the rain. It’s assumed that after a good rain, food is washed down to the jellyfish, and they instinctively realize this.
These jellyfish are also known as sea wasps and marine stingers. Their primary habitat is in water off of Northern Australia and in the Indo-Pacific. A box jellyfish has venom that’s so deadly, it regarded as one of the worst poisons on the planet today. This venom is so powerful that the toxins set about attacking the heart and nervous system, as well as skin cells. Their venom was designed so that it would immediately paralyze or kill its prey, and so that there was less of a battle. This way, the box jellyfish would look after its delicate tentacles. Box jellyfish eat small fish and crustaceans.
The sting is so deadly; help must be received immediately if one expects to survive. The pain is said to be excruciating, and those who do survive experience a lot of pain for weeks to months after being stung. There’s also generally scarring that can occur from the tentacles. The sting is proportionate to the size of the individual; for example, a young child needs less of a sting to cause dire results than an adult.
