Myopsida

Loliginidae, commonly known as pencil squids, is an aquatic family of squid classified in the order Myopsida.

Myopsida is one of the four orders of squid. It consists of two families: the monotypic Australiteuthis and the diverse and commercially important Loliginidae (~50 species). Some taxonomists classify this taxon as a suborder of the order Teuthida, in which case it is known as Myopsina. This reclassification is due to Myopsina and Oegopsina not being demonstrated to form a clade.

Australiteuthis aldrichi is a small species of squid found in northern Australian waters. The species was described by Chung Cheng Lu in 2005 based on specimens collected in the inshore waters of Northern Australia. The largest known individual of this species is a mature female measuring in mantle length (ML). The holotype is a mature male of ML. A live specimen of A. aldrichi has yet to be recorded.
