common bobtail

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.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
