supion

The common bobtail (<em>Sepietta oweniana</em>) is a small cephalopod mollusc found in the coastal waters of Denmark, Norway, and Sweden. This species typically inhabits European marine ecosystems, often occupying shallow to moderately deep benthic environments along the coastline. As a member of the family Sepiolidae, the common bobtail is a squid-like creature well adapted to life on or near the seafloor. It is classified as Least Concern on the IUCN Red List, reflecting a stable population status across its European range. The species often uses cryptic coloration and burrowing behavior to avoid predation in its marine habitats. It is typically a carnivore, feeding on small crustaceans and fish, and is itself an important prey species for larger marine predators in the North Sea and surrounding waters. Biological traits of this species remain poorly documented in the scientific literature.
