Description
Jellyfish have no brains, heart, or eyes: These fish are mostly made up of about 95% water. They also have no bones, and their body is primarily controlled by the nervous system.
These fish are bioluminescent – which means that they can produce their light. A group of jellyfish is called a smack. Jellyfish usually live for only about three to six months. However, some types can live for two to three years and some others are even immortal.
Jellyfish go by the scientific name Scyphozoa and belong to the kingdom Animalia and phylum Cnidaria. Scyphozoa comes from two Greek words – skuphos and zōion. While skuphos means “drinking cup,” the word zōion means “animal.” The name is an interpretation to mean that this animal contains water. The phylum cnidaria is interesting as well since it comes from the modern Latin word knidē, which means “nettle.”
Jellyfish have tentacles that are equipped with tiny stinging cells that are activated when these fish when they launch a sting attack on their prey. These tentacles are used to paralyze and stun the prey that the jellyfish stings. These tentacles are found hanging from the jellyfish’s body. Though these tentacles are controlled by the nervous system, the sting is rarely fatal. The purpose of the tentacles is to stop the movement of its prey, though they are also used as a defense. The biggest threats to the Jellyfish are sharks, birds, tuna, and sea anemone.
