The Box Jellyfish (Chirodropus sp.) is a marine (saltwater) planktonic scyphozoan in the Chirodropidae family of venomous box jellyfish. It belongs to the Cubozoa class. It is a cnidarian. It is also known as the Sea Wasp.
The medusa form of the Box Jellyfish has a cube-shaped, or box-shaped, bell. From each of the four lower corners hangs short stalks called pedalium which have about 15 slender, hollow tentacles. The rim of the bell is folded inwards to form a shelf known as a velarium. The velarium creates jet propulsion, which makes it move through the water.
In the centre of the box is a manubrium, which looks like an elephant’s trunk. This is where its mouth is located. Other jellyfish have ocelli, which are light sensing organs, instead of eyes. However, the Box Jellyfish has about 20 ocelli in addition to true eyes, set in a cluster, with retinas, corneas, and lenses. The eyes are located in pockets halfway up the outer, flat surface of the bell.
