They usually have some dark while some frilly tentacles. A jellyfish subject to predation will try virtually everything within its power to protect its delicate body, especially given the fact that are slow moving creatures that mostly rely on drift and ocean currents for their locomotion. Native to the shallow waters of Northern Australia and the Indo-Pacific region, the Box is considered to be one of the most poisonous sea creatures. The crystal jelly ( Aequorea victoria) has been called "the most influential bioluminescent marine organism." This cnidarian possesses green fluorescent protein (GFP) and a photoprotein (or a protein that gives off light) called aequorin, both of which are used in laboratory, clinical and molecular research. They can grow up to 300mm in diameter and deliver mild stings, typically appearing from May to September. The eggs and spermatozoa mature daily in the medusa gonads, given enough food, and are free-spawned into the water column in response to a daily light cue, where they are fertilized and eventually settle out to form a new hydroid colony. 3 What is the lifespan of a crystal jellyfish? Singichetti, B. BC, Canada Science. These determined creatures are called the jellyfish predators and this article is all about them. When in close range with their target, the nematocysts (poisonous cells) present in the tentacles release the harpoons and filaments, releasing toxic substances that paralyze their prey.

This species is rarely bioluminescent in nature but by placing it under a black (UV) light the GFP can be observed. Therefore, they require direct contact with their prey in order to feed which is effectively done through energetic propulsion in which pressure allows them to passively move in their environment.[7]. In some locations humans have simply been hunting them in large nets to get rid of them. The moon jellyfish, or moon jelly, is found throughout the world's oceans.
