Tasselled Scorpionfish
''Scorpaenopsis oxycephalus'', the tasseled scorpionfish, or small-scaled scorpionfish, is a species of venomous marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. It has a wide distribution in the Indian and Pacific Oceans. It is the largest species in its genus. Taxonomy ''Scorpaenopsis oxycephalus'' was first formally described as ''Scorpaena oxycephalus'' in 1849 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker with the type locality given as Jakarta on Java. The specific name is a compound of ''oxy'' which means "sharp" and ''cephalus'' meaning "head", an allusion to the long snout of this fish. Description ''Scorpaenopsis oxycephalus'' has an elongate body which becomes compressed towards the rear with a narrow ontraorbital space. The upper posttemporal and upper opercular spines are simple. The occipital pit is either absent or very shallow. It has a very long snout and in adults there are numerous tentacles which for ...

Pieter Bleeker
Pieter Bleeker (10 July 1819 – 24 January 1878) was a Dutch medical doctor, Ichthyology, ichthyologist, and Herpetology, herpetologist. He was famous for the ''Atlas Ichthyologique des Indes Orientales Néêrlandaises'', his monumental work on the fishes of East Asia published between 1862 and 1877. Life and work Bleeker was born on 10 July 1819 in Zaandam. He was employed as a medical officer in the Royal Netherlands East Indies Army from 1842 to 1860, (in French). stationed in the Dutch East Indies (now Indonesia). During that time, he did most of his ichthyology work, besides his duties in the army. He acquired many of his specimens from local fishermen, but he also built up an extended network of contacts who would send him specimens from various government outposts throughout the islands. During his time in Indonesia, he collected well over 12,000 specimens, many of which currently reside at the Naturalis Biodiversity Center in Leiden. Bleeker corresponded with Auguste Dum� ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Bycatch
Bycatch (or by-catch), in the fishing industry, is a fish or other marine species that is caught unintentionally while fishing for specific species or sizes of wildlife. Bycatch is either the wrong species, the wrong sex, or is undersized or juveniles of the target species. The term "bycatch" is also sometimes used for untargeted catch in other forms of animal harvesting or collecting. Non- marine species ( freshwater fish not saltwater fish) that are caught (either intentionally or unintentionally) but regarded as generally "undesirable" are referred to as rough fish (mainly US) or coarse fish (mainly UK). In 1997, the Organisation for Economic Co-operation and Development (OECD) defined bycatch as "total fishing mortality, excluding that accounted directly by the retained catch of target species". Bycatch contributes to fishery decline and is a mechanism of overfishing for unintentional catch. The average annual bycatch rate of pinnipeds and cetaceans in the US from 1990 t ...

Spearfishing
Spearfishing is fishing using handheld elongated, sharp-pointed tools such as a spear, gig, or harpoon, to impale the fish in the body. It was one of the earliest fishing techniques used by mankind, and has been deployed in artisanal fishing throughout the world for millennia. Early civilizations were familiar with the custom of spearing fish from rivers and streams using sharpened sticks. Modern spearfishing usually involves the use of underwater swimming gear and slingshot-like elastic spearguns or compressed gas powered pneumatic spearguns, which launch a tethered dart-like projectile to strike the target fish. Specialised techniques and equipment have been developed for various types of aquatic environments and target fish. Spearfishing uses no bait and is highly selective, with no by-catch, but inflicts lethal injury to the fish and thus precludes catch and release. Spearfishing may be done using free-diving, snorkelling, or scuba diving techniques, but spearfish ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Christmas Island
Christmas Island, officially the Territory of Christmas Island, is an States and territories of Australia#External territories, Australian external territory in the Indian Ocean comprising the island of the same name. It is about south of Java and Sumatra and about north-west of the closest point on the mainland Australia, Australian mainland. It has an area of . Christmas Island's geographic isolation and history of minimal human disturbance has led to a high level of endemism among its flora and fauna, which is of interest to scientists and naturalists. The territory derives its name from its discovery on Christmas Day 1643 by Captain William Mynors. The first European to sight Christmas Island was Richard Rowe of the ''Thomas'' in 1615. Mynors gave it its name. It was first settled in the late 19th century, after abundant phosphate deposits were found, originally deposited as guano, leading Britain to annex the island in 1888 and begin commercial mining in 1899.

Timor Sea
The Timor Sea (, , or ) is a relatively shallow sea in the Indian Ocean bounded to the north by the island of Timor with Timor-Leste to the north, Indonesia to the northwest, Arafura Sea to the east, and to the south by Australia. The Sunda Trench marks the deepest point of the Timor Sea with a depth of more than 3300 metres, separating the continents of Oceania in the southeast and Asia to the northwest and north. The Timor sea is prone to earthquakes and tsunamis north of the Sunda Trench, due to its location on the Ring of Fire as well as volcanic activity and can experience major cyclones, due to the proximity from the Equator. The sea contains a number of reefs, uninhabited islands and significant hydrocarbon reserves. International disputes emerged after the reserves were discovered resulting in the signing of the Timor Sea Treaty. The Timor Sea was hit by the worst Montara oil spill, oil spill for 25 years in 2009. It is possible that Australia's first inhabitants cros ...

New Guinea
New Guinea (; Hiri Motu: ''Niu Gini''; , fossilized , also known as Papua or historically ) is the List of islands by area, world's second-largest island, with an area of . Located in Melanesia in the southwestern Pacific Ocean, the island is separated from Mainland Australia, Australia by the wide Torres Strait, though both landmasses lie on the same continental shelf, and were united during episodes of low sea level in the Pleistocene glaciations as the combined landmass of Sahul. Numerous smaller islands are located to the west and east. The island's name was given by Spanish explorer Yñigo Ortiz de Retez during his maritime expedition of 1545 due to the perceived resemblance of the indigenous peoples of the island to those in the Guinea (region), African region of Guinea. The eastern half of the island is the major land mass of the nation of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Pap ...
