Bythaelurus Hispidus
The bristly catshark (''Bythaelurus hispidus'') is a cat shark of the family Scyliorhinidae, found from southeastern India and the Andaman Islands, between latitudes 15° N and 5° N, at depths between 200 and 300 m. Its length usually ranges from around 20–26 cm, and it is regarded as the smallest catshark of ''Bythaelurus''. Taxonomy Bristly catsharks were first discovered by Alfred William Alcock in the Indian Ocean in 1891. The specific word, hispidus, is thought to represent the papillae that generally appeared in species live in Andaman Sea. However, it was not named as ''alcockii''. Instead, the species named ''Halaelurus alcockii'', also known as ''Bythaelurus alcockii'', is another kind of catshark commonly known as Arabian catshark discovered by a German in 1913. Appearance and habitat The bristly catshark is a small species among the shark family, and as the name suggests, it has lengthened, cat-like eyes on the side that help it to be easily d ...

Alfred William Alcock
Alfred William Alcock (23 June 1859 in Bombay – 24 March 1933 in Belvedere, Kent) was a British physician, naturalist, and carcinologist. Early life and education Alcock was the son of a sea-captain, John Alcock in Bombay, India who retired to live in Blackheath. His mother was a daughter of Christopher Puddicombe, the only son of a Devon squire. Alcock studied at Mill Hill School, at Blackheath Proprietary School and at Westminster School. In 1876 his father faced financial losses and he was taken out of school and sent to India in the Wynaad district. Here he was taken care of by relatives engaged in coffee-planting. As a boy of 17 he spent time in the jungles of Malabar. Career Coffee-planting in Wynaad declined and Alcock obtained a post at a commission agent's office in Calcutta. This office closed soon, and he worked from 1878 to 1880 in Purulia as an agent recruiting unskilled labourers for the Assam tea gardens. While here an acquaintance, Duncan Cameron, le ...

Bythaelurus
''Bythaelurus'' is a genus of deep-water catsharks and part of the family Scyliorhinidae. The genus ''Bythaelurus'' Compagno 1988 was first described as a subgenus of ''Halaelurus'' Gill 1862 based on several morphological characteristics including a soft body with thin skin, a bluntly rounded snout without a pointed, knob-like tip, and eyes not noticeably elevated on the dorsal surface of the head. Members of this genus are generally found in deep water and have more somber body coloration. Species There are currently 14 recognized species in this genus: * ''Bythaelurus alcockii'' ( Garman, 1913) (Arabian catshark) * ''Bythaelurus bachi'' Weigmann ''et al.'', 2016 (Bach's catshark) * ''Bythaelurus canescens'' ( Günther, 1878) (dusky catshark) * ''Bythaelurus clevai'' ( Séret, 1987) (broadhead catshark) * ''Bythaelurus dawsoni'' ( S.

Thailand
Thailand ( ), historically known as Siam () and officially the Kingdom of Thailand, is a country in Southeast Asia, located at the centre of the Indochinese Peninsula, spanning , with a population of almost 70 million.

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised.

Cat Shark
Catsharks are ground sharks of the family Scyliorhinidae. They are the largest family of sharks with around 160 species placed in 17 genera. Although they are generally known as catsharks, some species can also be called dogfish due to previous naming. However, a dogfish may generally be distinguished from a catshark as catsharks lay eggs while dogfish have live young. Like most bottom feeders, catsharks feed on benthic invertebrates and smaller fish. They are not harmful to humans. The family is paraphyletic, containing several distinct lineages that do not form a monophyletic group. Genera The family includes 17 genera and over 150 species, making it the largest family of sharks. * '' Akheilos'' White, Fahmi & Weigmann, 2019 * ''Apristurus'' Garman, 1913 * ''Asymbolus'' Whitley, 1939 * ''Atelomycterus'' Garman, 1913 * ''Aulohalaelurus'' Fowler, 1934 * ''Bythaelurus'' Compagno, 1988 * ''Cephaloscyllium'' T.

15th Parallel North
The 15th parallel north is a circle of latitude that is 15 degrees north of the Earth's equatorial plane. It crosses the Saharan fringe (the Sahel) in Africa, three key peninsulars of Asia (between which parts of the Indian Ocean), the Pacific Ocean, an isthmus of Central America, the southern Caribbean and the Atlantic Ocean. In the Chadian-Libyan conflict of 1978 to 1987, its intra-Chad part came to be known as the "Red Line", separating opposing combatants, above all in Operation Manta.
