Loliginidae
Loliginidae is a family of squid that are commonly called pencil squid due to their elongated, cylindrical bodies. They are a widespread and diverse group, with species found in all oceans except the Arctic Ocean. These squid are known for their speed, intelligence, and predatory habits.
Common Names
Members of the Loliginidae family are often called pencil squid, but some species have other common names. For example, the European squid (Loligo vulgaris) is also known as the common squid or calamari.
Characteristics
Loliginidae squid share several distinguishing features:
- Elongated body: They have a slender, torpedo-shaped body that is typically longer than it is wide.
- Two long, pointed fins: These fins are located near the tail end of the body and help them maneuver through the water.
- Ten arms: They have eight arms and two longer tentacles, each with suckers that help them capture prey.
- Sharp beak: Their beaks are used to tear and chew food.
- Ink sac: Like other squid, they have an ink sac that releases a cloud of ink to confuse predators.
Environments
Loliginidae squid are found in a variety of marine environments, from shallow coastal waters to deep ocean trenches. They are generally found in areas with abundant food sources, such as fish, crustaceans, and other squid. They can tolerate a range of temperatures, but prefer warmer waters.
