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
L. 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
The 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.
