The box jellyfish has its title as they are bell shaped or cubed shaped with four sides being very prominent, thus the title box jellyfish. They may be as long as 20 cm on each side of the cube, and have up to 15 tentacles on each corner. These can be 3 meters in length and have 5,000 stinging cells on each of them. These tentacles are not actually triggered by any type of touch, rather, this species of jellyfish stings because it senses a presence of a form of chemical on the exterior of their prey.
A box jellyfish is extremely mobile, using their bodies to propel themselves forward at speeds up to 4 knots. These kinds of jellyfish travel towards the shores in the calmer weather, and settle around the mouths of both creeks and rivers following the rain. It’s assumed that after a great rain, food is washed down to the jellyfish, and they intuitively realize this.
These jellyfish are also called sea wasps and marine stingers. Their main habitat is in water off of Northern Australia and in the Indo-Pacific. A box jellyfish has venom that’s so deadly, it considered to be one of the worst poisons in the world today. This venom is so strong that the toxins set about attacking the heart and nervous system, as well as skin cells. Their venom was designed so that it would instantly paralyze or kill its prey, and also so that there was less of a battle. In this manner, the box jellyfish will take care of its delicate tentacles.
If a human is stung by a this jellyfish, it is entirely possible for them to go into shock or even heart failure, drowning before receiving aid. The sting is so deadly; help must be received immediately if one hopes to survive. The pain is reported 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 Rodent Control. The sting is proportionate to the size of the individual; for example, a young child needs less of a sting to cause dire consequences compared to an adult.
