Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
This species is known only from young specimens caught off the coast of Oregon (Hochberg and Young 2006). Gonatids are medium sized oceanic squid that occur over a wide depth range from near the surface to more than 1,000 m in depth (Kubodera et al. 2006). Generally their planktonic paralarvae young are most abundant between 200-300 m in depth and highest abundances appear to occur over the continental slopes in summer (Okutani and Clarke 1992). Gonatus species attain a maximum mantle length of 400 mm (Kubodera et al. 2006).

Justification
Very little is known about Gonatus oregonensis, making it impossible to make an accurate assessment of its extinction risk. It is also only known from a very small area, off the coast of Oregon, USA. We therefore consider it to be Data Deficient. Further research is recommended in order to better understand the precise distribution, population dynamics, life history and ecology, and the potential threat processes affecting this species.
