The Bigfin Reef Squid, also known as Sepioteuthis lessoniana, is a species of cephalopod that can be found in the tropical and subtropical waters of the Indo-Pacific region. In this article, we will explore the characteristics, behavior, and habitat of the Bigfin Reef Squid.
Physical Characteristics
The Bigfin Reef Squid is a relatively large species of squid, with an average mantle length of 20 to 30 cm (8 to 12 inches) and a total length of up to 60 cm (24 inches). They have a slender body with long, thin fins that extend almost the entire length of their mantle.

They can change their coloration in just milliseconds, allowing them to blend into their surroundings and avoid detection.
Habitat
Bigfin Reef Squid can be found in a variety of shallow-water habitats, including coral reefs, seagrass beds, and rocky shorelines. They are also known to inhabit deeper waters, up to 200 m (656 ft) below the surface. They are most commonly found in the warm waters of the Indo-Pacific region, from the coast of Africa to the western Pacific Ocean.
Conclusion
In summary, the Bigfin Reef Squid is a fascinating and unique species of cephalopod that is known for its impressive hunting skills and remarkable ability to change color and texture. It is an important member of the marine ecosystem and can be found in a variety of shallow and deep-water habitats throughout the Indo-Pacific region.
