Oegopsida. Oegopsida is one of the two orders of squid in the superorder Decapodiformes, in the class Cephalopoda. Together with the Myopsina, it was formerly considered to be a suborder of the order Teuthida, in which case it was known as Oegopsina. This reclassification is due to Oegopsina and Myopsina not being demonstrated to form a clade.

The Oegopsida are an often pelagic squid, with some nerito-oceanic species associated with sea mounts. They consist of 24 families and 69 genera. They have these characters in common: the head is without tentacle pockets, eyes lack a corneal covering, arms and tentacle clubs may have hooks, the buccal supports are without suckers, and oviducts ...

Oct 1, 2021 · The nad2 and nad3 gene blocks could have changed position several times in the evolutionary history of Oegopsida (see Discussion), but we cannot establish this via short-read sequencing; hence, we assumed that our samples had the genome order depicted in Figure 2E, as initially established for Todarodes pacificus (Steenstrup, 1880) and ...
