Squid diversity in the micronekton of the Eastern Tropical Pacific is low, with only 15 species reported from the families Enoploteuthidae, Onychoteutidae, Cranchiidae, Histioteuthidae and Ommastrephidae (Blackburn, 1968).
Cephalopods comprised 97%N of the total items identified and included 11 taxa from 5 families: Gonatidae (69.4%N), Cranchiidae (18.4%N), Octopoteuthidae (5.8%N), Vampyroteuthidae (2.9%N), and Histioteuthidae (0.5%N).
In the Cranchiidae and Lycoteuthidae, arm-tip photophores develop as secondary sexual characters (Herring et al., 1992).
Gladii of bobtail squid and several squid families (Chtenopterygidae, Thysanoteuthidae, Mastiogoteuthidae, Chiroteuthidae, and Cranchiidae) consist only of two, or even one (Bathyteuthidae), layers (Bizikov 2008).
Non-ommastrephid cephalopods were identified in many of the tows, most commonly as taxa in the teuthid families Enoploteuthidae, Onychoteuthidae, Gonatidae, Chtenopterygidae, Cranchiidae, and Brachioteuthidae and in the octopod genera Argonauta and Tremoctopus; all have previously been reported from the ETP (Ueyanagi and Nonaka, 1993; Vecchione, 1999).
Among the exclusively pelagic squid, only the Cranchiidae and small specimens of certain chiroteuthids (e.g., Chiroteuthis) display any significant transparency.

For example, members of the family Cranchiidae (including Cranchia and Liocranchia, the contrast excluded from several of the analyses) have low metabolic rates regardless of habitat depth.

The diet of lancetfish consists of pelagic crustaceans (Hyperiidae, Portunidae, Amphipoda), cephalopods of the families Onychoteuthidae, some Ommastrephidae (Ornithoteuthis volatilis), Cirroteuthidae, Octopodidae, Argonautidae, Cranchiidae, Histioteuthidae, Bathyteuthidae, and mesopelagic fishes (Sternoptyx diaphana, Paralepis elongata, Omosudis lowei, A.
