Muusoctopus levis is a species of octopus in the family Enteroctopodidae. [1] It was first described by William Evans Hoyle in 1885 in an article in the Annals and Magazine of Natural History detailing the new species of octopus found on HMS Challenger as part of the Challenger expedition; the type specimen was retrieved from the Southern Ocean. [2]
A new study found that some members of an octopus species hunt cooperatively in groups with fish. Video shows octopuses punching their companion fish to keep them on task and contributing to the hunt.
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.
Pinnoctopus cordiformis is known as a reef octopus, and has been found around New Zealand in Stewart Island (47˚S) to the south of Leigh (36˚S); they have also been found in the Chatham Islands (35˚S to 48˚S). [5] [6] It is one of the most common species of octopus in the country. [7]
Grimpoteuthis imperator, also known as the Emperor Dumbo octopus, is a species of deep-sea octopus in the family Grimpoteuthidae. The species is known from a single male specimen found in the Emperor Seamounts in the north Pacific off the coast of Japan in 2021. It was found at depths of 3900–4400m. [1]
In recent years new technology, such as genome sequencing, has provided new information on the large amounts of clustered protocadherins (PCDH) in O. bimaculoides. The octopus was found to have 168 PCDH genes, about 120 clustered and 50 non-clustered PCDH.
The major neurotoxin component of the blue-ringed octopus is a compound originally known as "maculotoxin"; in 1978, this maculotoxin was found to be tetrodotoxin, [17] a neurotoxin also found in pufferfish, rough-skinned newts, and some poison dart frogs; the blue-ringed octopus is the first reported instance in which tetrodotoxin is used as a ...
Mimic octopus showing typical pattern. The mimic octopus was first discovered off the coast of Sulawesi, Indonesia in 1998 on the bottom of a muddy river mouth. [5] [6] It has since been found to inhabit the Indo-Pacific, ranging from the Red Sea and Gulf of Oman in the west to New Caledonia in the east, and Gulf of Thailand and the Philippines in the north to the Great Barrier Reef in south.
