The common blanket octopus or violet blanket octopus (Tremoctopus violaceus) [4] is a large octopus of the family Tremoctopodidae found worldwide in the epipelagic zone of warm seas. The degree of sexual dimorphism in this species is very high, with females growing up to two meters in length, whereas males grow to about 2.4 cm.
This octopus is native to the Great Barrier Reef [1] and is often found throughout the Indo-West Pacific Ocean. There are six other species of octopuses within the subgenus Abdopus with a large number of organisms not yet described. [3] This octopus is notable for its unique body patterning through which it can change.
Like many other octopuses, the blanket octopus uses ink to intimidate potential predators. [7] Also, when threatened, the female unfurls her large net-like membranes that spread out and billow in the water, greatly increasing her apparent size. Blanket octopuses usually live in coral reefs, where they hunt for food, which consists of small fish.
The Andros Barrier Reef [18] is the world's sixth longest. [19] It runs for 225 km (140 mi), averaging a distance of 2–3 km (1–2 mi) from the Andros shore. [20] The extensive flats of the Great Bahama Bank lie to the west, northwest and south of Andros.
The Great Barrier Reef is showing signs of repair. The reef has been suffering from a large amount of ocean bleaching due to the rise in ocean temperatures. Unfortunately, the Great Barrier Reef ...
During that time, between 2016 and 2024, the Great Barrier Reef, the world’s largest coral reef ecosystem and one of the most biodiverse, suffered mass coral bleaching events.
In some lineages, such as the blanket octopus, males become structurally smaller and smaller resembling a term, "dwarfism" dwarf males usually occurs at low densities. [128] The blanket octopus male is an example of sexual-evolutionary dwarfism; females grow 10,000 to 40,000 times larger than the males and the sex ratio between males and ...
The Great Barrier Reef has long been known to and used by the Aboriginal Australian and Torres Strait Islander peoples, and is an important part of local groups' cultures and spirituality. [citation needed] [clarification needed] The first European to sight the Great Barrier Reef was James Cook in 1770, who sailed and mapped the east coast of ...
