William Evans Hoyle
Dr William Evans Hoyle FRSE (28 January 1855 – 7 February 1926) was a noted British zoologist. A specialist in deep sea creatures he worked on classification and illustrations from the Challenger Expedition from 1882 to 1888. Life Hoyle was born in Manchester the son of William Jennings Hoyle, an engraver. He was educated at Owens College and at Exeter College and Christ Church, Oxford where he obtained a Bachelor of Arts in 1877, Master of Arts in 1882 and a Doctor of Science, he was also Member of the Royal College of Surgeons. He was the Director of the Manchester Museum from 1889 to 1909 and then was the first director of the National Museum of Wales from 1909 up to his retirement in 1926. Trained as a medical anatomist, Hoyle is most famous for his monographic studies on cephalopods from major exploring expeditions of his era including the Challenger, the Albatross, the British National Antarctic Expedition and the Scottish National Antarctic Expedition.

Enteroctopus Dofleini2
''Enteroctopus'' is an octopus genus whose members are sometimes known as giant octopus. Etymology The generic name ''Enteroctopus'' was created by Alphonse Tremeau de Rochebrune and Jules François Mabille in 1887 and published in 1889, joining Ancient Greek 'gut' and , thus 'octopus [with arms similar to] guts.' Description ''Enteroctopus'' is a genus of generally temperate octopuses. Members of this genus are characterized by their large size and are often known as giant octopuses. ''Enteroctopus'' species have distinct longitudinal wrinkles or folds dorsally and laterally on their bodies. Their heads are distinctly narrower than the mantle width. The hectocotylus of the males in this genus, found on the third right arm, is long and narrow in comparison with other genera in the family Octopodidae, often comprising one-fifth the length of the arm. Octopuses in this genus have large, paddle-like wiktionary:Papilla, papillae instead of the more conical papillae in other oc ...

British National Antarctic Expedition
The ''Discovery'' Expedition of 1901–1904, known officially as the British National Antarctic Expedition, was the first official British exploration of the Antarctic regions since the voyage of James Clark Ross sixty years earlier (1839–1843). Organized on a large scale under a joint committee of the Royal Society and the Royal Geographical Society (RGS), the new expedition carried out scientific research and geographical exploration in what was then largely an untouched continent. It launched the Antarctic careers of many who would become leading figures in the Heroic Age of Antarctic Exploration, including Robert Falcon Scott who led the expedition, Ernest Shackleton, Edward Wilson, Frank Wild, Tom Crean and William Lashly. Its scientific results covered extensive ground in biology, zoology, geology, meteorology and magnetism. The expedition discovered the existence of the only snow-free Antarctic valleys, which contains the longest river of Antarctica. Further ach ...

''Sepia cultrata'', commonly known as the knifebone cuttlefish or elongated cuttlefish, is a species of cuttlefish from the family Sepiidae endemic to the southern Indo-Pacific. It is a deepwater species found in subtropical and temperate Australian waters. Description ''Sepia cultrata'' has a pale buff pinkish brown colour. It has a crescent-shaped club with a flattened sucker bearing 5 or 6 small suckers in transverse rows. The cuttlebone is an elongate oval shape with triangular pointed anterior and narrow posterior ends.

Pyroteuthis
''Pyroteuthis'' is a genus of squid in the family Pyroteuthidae. It is differentiated from the genus '' Pterygioteuthis'' by size, head shape and behaviour. Species within the genus are separated by the arrangement of tentacular photophores; the shape of the hectocotylus, and the shape of the hectocotylus hooks. With the exception of the Tropical Eastern Pacific, the genus is circumpolar in tropical and temperate oceans. The species '' P. addolux'' is the only member to occur in the North Pacific The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continen ....

Muusoctopus Levis
''Muusoctopus levis'' is a species of octopus in the family Enteroctopodidae. 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 as part of the ''Challenger'' expedition; the type specimen was retrieved from the Southern Ocean. The species is found in subantarctic waters in the Southern Ocean, particularly surrounding Heard Island and Kerguelen Island, but specimens comparable to ''M. levis'' have also been found at the Antarctic Peninsula. Description It is known to inhabit shallow depths between . It is predatory, living and feeding in the benthic zone, where it feeds heavily on brittle stars. In a study in which the stomach contents of 70 specimens were examined, around 50 were shown to have fed only on brittle stars. A study on the reproductive strategies of coleoid cephalopods concluded, while "a simultaneous terminal spawning strategy is most likely" for ''M. l ...

''Metasepia pfefferi'', also known as the flamboyant cuttlefish, is a species of cuttlefish occurring in tropical Indo-Pacific waters off northern Australia, southern New Guinea, as well as numerous islands of the Philippines, Indonesia and Malaysia. The flesh of this colorful cephalopod contains unique acids, making it unsuitable for consumption.NOVA, 2007. Cuttlefish: Kings of Camouflage. [television program] NOVA, PBS, April 3, 2007.

Southern Blue-ringed Octopus
The southern blue-ringed octopus (''Hapalochlaena maculosa'') is one of three (or perhaps four) highly venomous species of blue-ringed octopuses. It is most commonly found in tidal rock pools along the south coast of Australia. As an adult, it can grow up to long (top of the mantle to the tip of the arms) and on average weighs . They are normally a docile species, but they are highly venomous Venom or zootoxin is a type of toxin produced by an animal that is actively delivered through a wound by means of a bite, sting, or similar action. The toxin is delivered through a specially evolved ''venom apparatus'', such as fangs or a sti ..., possessing venom capable of killing humans. Their blue rings appear with greater intensity when they become aggravated or threatened. Description The blue-ringed species are known for their small size, yet the southern variety is hailed as the largest of the genus. As a result, they have been classified as their own species.

James Cossar Ewart
James Cossar Ewart FRS FRSE (26 November 1851 – 31 December 1933) was a Scottish zoologist. He performed breeding experiments with horses and zebras which disproved earlier theories of heredity. Life Ewart was born in Penicuik, Midlothian, Scotland, the son of Jean Cossar and John Ewart, a joiner. He studied medicine from 1871 to 1874 at the University of Edinburgh where he graduated with an MB ChB. After graduation, he became an anatomy demonstrator under William Turner and then held the position of Curator of the Zoological Museum at University College, London, where he assisted Ray Lankester (later director of the Natural History Museum) by making zoological preparations for the museum and providing teaching support for Lankester's course in practical zoology. In 1878 he returned to Scotland to take a post of Regius Professor of Natural History at the University of Aberdeen from where he moved to the University of Edinburgh in 1882, staying in the post until 1927. ...
