There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

There's a new squid in town, but it doesn’t look like most other squids: https://cosmosmagazine.com/biology/there...id-in-townhttps://www.nature.com/articles/s42003-019-0661-6

Japanese and Australian scientists have identified this new species of bobtail squid in the waters around Japan’s Okinawa islands. The work was led by researchers from the Okinawa Institute of Science and Technology (OIST) Graduate University, and they have named the new discovery Euprymna brenneri in honour of one of OIST’s founders, Sydney Brenner. It is the eleventh known species in the genus Euprymna, and will be useful in future phylogenetic and comparative studies, they say. Bobtails are more closely related to cuttlefish than other squids, and have a few unique features, notably the rounded or "bobbed" posteriors that have earned them the nickname "dumpling squid". They also can be raised in the laboratory, making them useful as a model for studying cephalopod development, genetics and behaviour.

Squids are members of the class Cephalopoda, subclass Coleoidea. The squid orders Myopsida and Oegopsida are in the superorder Decapodiformes (from the Greek word for "ten-legged"). Two other orders of decapodiform cephalopods are also called "squid", although they are taxonomically distinct from squids and differ recognizably in their gross anatomical features. They are the bobtail squid of order Sepiolida and the ram's horn squid of the monotypic order Spirulida. The vampire squid (Vampyroteuthis infernalis), however, is more closely related to the octopuses than to any proper squid: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5813590/
