The octopus has been found as far south as Namibian waters and as far north as British waters. [5] In the early 1900s, many octopuses living all over the Atlantic and Indian oceans were classed as Opisthoteuthis grimaldii , but later scientists decided that only those specimens found in the Eastern Atlantic Ocean actually belonged to the species.
The informally named Casper octopus species were first discovered in 2016 in the Pacific Ocean, in water off Hawaii. [1] The two distinct Casper species are new to science but have not yet been formally named with a binomial name as no specimens have yet been collected - they are only known from imagery. [1]
Opisthoteuthis philipii is an octopus of the Indian Ocean. It lives off the coast of Kerala, India. [ 3 ] Known specimens were found between 275–365 m (902–1,198 ft) deep in the Arabian Sea [ 1 ] near Alappuzha .
Some species are adapted to the cold, ocean depths. The spoon-armed octopus (Bathypolypus arcticus) is found at depths of 1,000 m (3,300 ft), and Vulcanoctopus hydrothermalis lives near hydrothermal vents at 2,000 m (6,600 ft). [29] The cirrate species are often free-swimming and live in deep-water habitats. [38]
In the video above, the scientist explains that this particular species of octopus has "beaks for mouths and their brains are donut-shaped and surround their esophagus.
Researchers believe the shorter brooding period near warm hydrothermal springs increases a hatchling octopus’ odds for survival. Mystery of octopus garden in ocean’s midnight zone solved by ...
The incirrate octopuses are distinguished from the cirrate octopuses by the absence in the former of the "cirri" filaments (found with the suckers) for which the cirrates are named, as well as by the lack of paired swimming fins on the head, and lack of a small internal shell (the "shell" of Argonauta species is not a true shell, but a thin ...
