Doryteuthis
Doryteuthis is a genus of squid belonging to the family Loliginidae. They are commonly referred to as “shortfin squid” due to their relatively small fins compared to other squid species. Doryteuthis are found in coastal waters worldwide, often inhabiting shallow waters and estuaries. They are characterized by their streamlined bodies, large eyes, and eight arms and two long tentacles. Their mantle can be a variety of colors, including brown, reddish-brown, and white, often with a mottled pattern.
Common Names
Doryteuthis squid are commonly known as:
- Shortfin squid

- Calamari squid
Characteristics
Doryteuthis species exhibit several distinguishing characteristics:
- Size: They typically range in size from 10 to 30 centimeters in mantle length.
- Body Shape: Their body is torpedo-shaped and streamlined, allowing for swift movement through water.
- Fins: Their fins are relatively small compared to other squid species, hence the name "shortfin squid."
- Arms and Tentacles: They have eight arms and two long tentacles, all equipped with suckers for capturing prey.
- Chromatophores: They possess chromatophores, specialized pigment cells that allow them to change color rapidly for camouflage and communication.
Environment
Doryteuthis squid are found in coastal waters around the globe, typically inhabiting:
- Shallow Waters: They are often found in shallow coastal waters, particularly near estuaries and bays.
- Temperate and Tropical Regions: They are most abundant in temperate and tropical regions, but some species are found in colder waters as well.
- Sandy Bottoms: They frequently inhabit areas with sandy or muddy bottoms, where they can find refuge and hunt for prey.
