Description
editDue to its morphological characteristics, L. argus could easily be confused with other species of its genus.It is found on soft bottoms and within the water column,[1] and the depths that it inhabits are usually between 0 and 70m from the surface. L. Argus has a maximum mantle sizes are 30mm for males and 39mm for females. It is the only known myopsid to have its primary hectocotylization on the right ventral arm instead of the left.[2]
Anatomy
editL. Argus is mainly characterized by their short, blunt mantle. The mantle has small fins, which are elliptical and take up about 25% of the total mantle length.[3] Its tentacles are short and compact, without buccal suckers.
Mating & Habits
editThe ovulation pattern in L. argus is asynchronous, with multiple-batch spawning in a relatively short period of time.[4] It breeds in the coastal waters off Puerto Ángel and in the Gulf of Tehuantepec. From some squid samples, three squid were discovered to have sardines in their stomachs.
