Blanket Octopus Animal Facts

• Size: Female blanket octopuses are significantly larger than males, with some species reaching up to six feet in length, while males are less than an inch long.
• 
  
• Arms: Like other cephalopods, blanket octopuses have eight arms, but their arms are connected by a web of skin, which gives them a distinct "blanket" appearance.
• 
  
• Mantle: The mantle is the main body of the octopus, and it is elongated and flattened in the blanket octopus. It also has a pair of fins on either side, which it uses for propulsion.
• 
  
• Color: Blanket octopuses are known for their vibrant coloration, with females displaying bright red, pink, or orange webbing between their arms. Males, on the other hand, are a pale blue color.
• 
  
• Sexual Dimorphism: As mentioned, the sexual dimorphism in the blanket octopus is extreme, with females being significantly larger and more colorful than males.

Blanket octopuses are found in tropical and subtropical waters around the world, including the Pacific, Atlantic, and Indian Oceans. The species is found in warm waters, typically between the surface and a depth of around 200 meters (650 feet).
Blanket octopuses are pelagic creatures, meaning they spend most of their time swimming in the open ocean, often far from shore. They are also known to inhabit areas near the surface, particularly around floating objects such as seaweed or debris.
These octopuses are known to have a broad range and have been observed in various regions of the world. Some species of blanket octopuses are known to inhabit deep-sea environments, although they are less commonly observed.
In terms of habitat, blanket octopuses are known to be particularly adapted to living in open ocean environments, where they can use their webbing to catch prey and to move quickly through the water. They are often found in warm, tropical waters with high levels of planktonic organisms and other small prey items.

Blanket Octopus Diet and Prey

The blanket octopus (Tremoctopus) is a carnivorous predator that feeds primarily on small fish and crustaceans. As an ambush predator, the blanket octopus uses its long, trailing tentacles to ensnare prey, using venomous suckers to subdue its victims.

In addition to their long tentacles, blanket octopuses are also equipped with a sharp, beak-like mouth that they use to tear into the flesh of their prey. Their diet primarily consists of small fish and crustaceans, but they have also been known to consume other mollusks and even other octopuses.
Interestingly, male blanket octopuses have a much smaller diet compared to their female counterparts and mainly feed on small crustaceans. This is likely due to their small size and lack of the specialized tentacles and webbing that the females use to capture larger prey.
Overall, the blanket octopus is a formidable predator that uses a combination of size, speed, and stealth to capture its prey. Their unique hunting strategies and specialized anatomy make them one of the most fascinating creatures of the deep sea.

The tentacles of the female blanket octopus can reach up to six feet in length, making them one of the longest of any octopus species. The tentacles are lined with rows of suckers, which are surrounded by a thin, transparent membrane that can expand to several times its normal size. This membrane allows the female blanket octopus to create the illusion of being much larger and more intimidating than she actually is, helping to deter potential predators.
