Some biologists believe that had the lifespan of octopuses been longer, they would have become one of the most intelligent and dominant ocean animals alive. Larger females that can carry more large eggs. The reason for this difference, as stated by some biologists points to the evolution of these species. The reasons for this behavior can be attributed to their opportunistic nature. When this deceptive trick does not work out, they are capable of detaching these blankets, causing the predator to be entangled in the web giving them enough time to escape. They belong to the family of Tremoctopodidaes and are seen in the Indo-Pacific waters. These octopuses break the tentacles of the jellyfish and are seen to use it to defend themselves from predators.

The female blanket octopus, which can grow to over 6 feet long (over 10,000 times the size of males), shows off their multi-colored webbing which changes colors as it moves. Blanket octopuses get their name from sheets of webbing that stretch between some of their arms. A Bizarre Defense Mechanism. In such a scenario, the male octopuses tend to reduce development time by maturing earlier, but this causes them to be smaller than an average male blanket octopus. Two extremely rare rainbow blanket octopuses were captured on camera during a night dive off the coast of Romblon, Philippines by Joseph Elayani. Another exciting factor about them is the presence of a circulatory system consisting of arteries, capillaries, and veins and are lined with a cellular endothelium. The juvenile females also use the tentacles of the Portuguese man o’ war, but as they grow larger, they abandon this strategy. The passage of water into the mantle cavity is achieved by contraction of radial muscles in the mantle wall, and flapper valves shut when strong circular muscles force the water out through the siphon. In fact, biologists say that octopuses are the most intelligent among the invertebrates. They are known for their tool use- they tear Portuguese man o'war tentacles off to use as weapons!

Tremoctopus is a genus of pelagic cephalopods, containing four species that occupy surface to mid-waters in subtropical and tropical oceans. The temperature in those depths will be very less than what is on the surface, and in such low temperatures, hemocyanin can carry oxygen more efficiently than hemoglobin. The little guys then break their small arm containing the sperms and swim away. These are the octopuses that belong to the family of Tremoctopodidaes that are found in the tropical and subtropical seas, mainly in the Atlantic Ocean. Some biologists also claim that natural selection may also have contributed to extreme dimorphism in this species. When a male blanket octopus finds a female, he doesn’t try to prove himself or convince her that he is the right guy.

Did you know that apart with showing sexual-dimorphism, these octopuses’ size also varies with the temperature of the water they live in? Diet – Prawns, Small fishes, and other Cephalopods The normal respiration process involves drawing water into the mantle cavity through an aperture, passing it through the gills, and expelling it through the siphon. The systemic heart is responsible for pumping the blood throughout their body while the two branchial hearts are responsible for pumping the blood through their pair of gills. How many hearts does an octopus have? IUCN Red List status – Least Concern, Unlike other members of the octopus’s family, the blanket octopuses have sheets of flesh stretched between their arms.

Yeah, not all blanket octopuses have this sheets of flesh between their tentacles. Human intervention hasn’t affected octopuses much, and their intelligence can he held a reason for it. Their ability to observe their surroundings and change color accordingly makes them capable of excellent camouflage which is also an example of their intelligence. The female octopuses are seen to take good care of the eggs as if she is obsessed with the eggs. When this was first recorded, in 1963, people thought they were getting bitten. When they mate, the hectocotylus detaches from the male’s body and the female keeps it in their mantle cavity until her eggs are all fertilized.

Their ability to observe their surroundings and change color accordingly makes them capable of excellent camouflage which is also an example of their intelligence. This drastic difference in size & weight is called sexual-size dimorphism. Though there are other species in the animal kingdom showing sexual-dimorphism none of them have such a startling difference as these blanket octopuses.

The hatched eggs are called larvae, and they are found to drift in the plankton clouds. This single number could reshape our climate future. When living in the plankton clouds, they are prone to be eaten by other species that survive on plankton. The larger the female, the larger the eggs/offspring’s she can carry. Also, the genus contains four currently known species that occupy surface to mid-waters in subtropical and tropical oceans. The world’s wetlands are slipping away. Size of the male does not matter in ensuring the sustenance of a gene because even a minuscule male can accommodate a large number of tiny male sperms.
