Sepioteuthis

The Sepioteuthis lessonian, also known as bigfinreef squid or oval squid, is widely distributed in neritic waters throughout the Indo-West Pacific, from Japan to northern Australia (Jereb and Roper 2010). According to research published in Variations in life-history traits and statolith shape for Sepioteuthis spp. in the waters off southwestern Japan, it plays a critical ecological role in many marine ecosystems, dominating various water columns, serving as both prey and predators to numerous marine organisms, and transferring energy between neritic and bottom waters, Several squid species share similar migratory patterns, inhabiting both inshore and offshore waters and aggregating near coasts for spawning once they reach maturity. One study from 2023 revealed that it exhibits temperature-dependent distribution patterns, with populations adapting to different thermal histories based on ambient water temperatures recorded in their statoliths. This trait may help the species cope with seasonal and regional climate variability. Despite its ecological importance and increasing interest in its potential for sustainable fisheries, the species remains understudied, with limited public awareness and few accessible resources. This summary aims to bring forward findings from older and specialized scientific literature that are not widely available online, helping to expand public understanding of this organism’s natural history.
