Sthenoteuthis oualaniensis occurs in a diverse range of environments in the tropical and subtropical Indo-Pacific, often at depths of over 600 m (1,969 ft) deep. [9] [6] [7] Total species biomass has been estimated at between 8-11 million tonnes; the Arabian Sea from November-January is thought to contain one of the highest concentrations (12 to 42 t km −2) of these squids due to population ...
Squid can expel up to 94% of the fluid within their cavity in a single jet thrust. [68] To accommodate the rapid changes in water intake and expulsion, the orifices are highly flexible and can change their size by a factor of 20; the funnel radius, conversely, changes only by a factor of around 1.5.

A video shows the long creature with tentacles and large eyes floating through the water and excreting a cloud of greenish-yellow ink. ... The squid was spotted more than 3,600 feet underwater ...
The bacteria are fed a sugar and amino acid solution by the squid and in return hide the squid's silhouette when viewed from below by matching the amount of light hitting the top of the mantle (counter-illumination). [13] E. scolopes serves as a model organism for animal-bacterial symbiosis and its relationship with A. fischeri has been ...
