Phronima

Phronima is a small, deep sea hyperiid amphipod of the family Phronimidae. It is found throughout the world's oceans, except in polar regions.[1] Phronima lives in the Pelagic zone of the deep ocean. The body of Phronima is semi-transparent. Although it is commonly known to be a parasite, a more technically correct term would be parasitoid.[2] Instead of constantly feeding off of a live host, females attack salps, using their mouth and claws to eat the animal and hollow out its gelatinous shell.[3] Phronima females then enter the barrel and lay their eggs inside. The parasitoid then propels the barrel through the water as the larvae develop, providing them with fresh food and water.[3]

Classification[edit]

The genus Phronima contains the following species:[4]

Influence[edit]

It has been said[9] that the creatures in the Alien franchise were inspired by Phronima.[10] Although some people believe that the Aliens in the Alien" movies were inspired by a painting done by H. R. Giger,[11] the similarities in appearance between Phronima and the so called xenomorphs from the Alien franchise are too great to ignore. The most obvious similarity is the large crest located on the top of the head of both creatures. Although the crest in the xenomorph species appears to act as some type of armor, this crest adorned by Phronima is actually a set of upward facing eyes. [12]
