Bajacalifornia is a genus of slickheads. It was described in 1925 by Charles Haskins Townsend and John Treadwell Nichols on the basis of Bajacalifornia burragei [1] which was discovered in 1911 during the deep sea expedition of the research vessel USS Albatross off the coast of Todos Santos Bay at the Baja California peninsula. [1] In 1952 Ichthyologist Albert Eide Parr published a revision of this genus. [2]
There are currently seven recognized species in this genus: [3]
The body is covered with small cycloid scales. The ventral scales are well developed. The mouth is moderately wide but larger than in the genus Alepocephalus . The lower jaw is strongly projected and ends in a pointed knob which is directed obliquely forwards. The jaw edges have a single row of small teeth. The gill raker openings are wide, the gill membranes are joined below. The short dorsal and anal fins are equal in length. [1]
The distribution area ranges from the Indian Ocean, the Indo-Pacific north to the Sea of Japan and eastwards to the East Pacific Rise.
Hemiramphidae is a family of fishes that are commonly called halfbeaks, spipe fish or spipefish. They are a geographically widespread and numerically abundant family of epipelagic fish inhabiting warm waters around the world. The halfbeaks are named for their distinctive jaws, in which the lower jaws are significantly longer than the upper jaws. The similar viviparous halfbeaks have often been included in this family.
Isla Todos Santos is a pair of islands about 19.3 km (12.0 mi) off Ensenada, Baja California, at 31°47′59″N116°47′20″W best known for surfing. Access is only by boat, which can be rented in Ensenada, or La Bufadora. The waves off the smallest island are among the biggest in North America. There are no facilities on the islands except for two lighthouses and a fish farm operation.
Slickheads, also known as nakedheads or smoothheads, are deep water fishes that belong to the family Alepocephalidae. They are most commonly found in the bathypelagic layer, which is approximately 3000m below the surface. They get their name from the lack of scales on their heads. Similarly, the scientific name is from the Greek ᾰ̓- (a-, "not"); λέπος (lepos, "scale"); and κεφαλή (kephalē, "head"). It has about 22 genera with ca. 96 species.
The sea toads and coffinfishes are a family of deep-sea anglerfishes known as the Chaunacidae.
Bothrocara is a genus of marine ray-finned fishes belonging to the family Zoarcidae, the eelpouts. They are found in the Pacific Ocean with one species reaching the southwestern Atlantic Ocean.
The Pacific ladyfish, also known as the Pacific tenpounder and machete, is a species of ray-finned fish in the genus Elops, the only genus in the monotypic family Elopidae. The Pacific ladyfish can be found throughout the southwest U.S. and other areas in the Pacific Ocean.
Mycteroperca is a genus of marine ray-finned fish, groupers from the subfamily Epinephelinae, part of the family Serranidae, which also includes the anthias and sea basses. They are predatory fish, largely associated with reefs and are found in tropical and subtropical seas in the Atlantic Ocean and the eastern Pacific Ocean. They are important target species for fisheries.
The barcheek trevally, also known as the barcheek kingfish, shortridge trevally or oblique-banded trevally, is a species of moderately large marine fish of the jack family Carangidae. The barcheek trevally is distributed throughout the tropical waters of the Indo-west Pacific region, ranging from South Africa in the west to Japan, Australia and a number of small central Pacific islands in the east. The species inhabits inshore and offshore waters, found along the slopes of lagoons and out to deeper reefs on the continental shelf, where it preys on small fish and benthic crustaceans. It is a moderately large fish, growing to a maximum recorded length of 50 cm, and can be distinguished from similar species by its somewhat protruding lower jaw and the dark banding on its operculum. It is of minor importance to fisheries throughout its range, taken by trawling, hook and line methods and various inshore fish netting methods.
The Wonderfish (Thaumatichthys) is a genus of deep-sea anglerfish in the family Thaumatichthyidae, with three known species. Its scientific name means "wonder-fish" in Greek; oceanographer Anton Bruun described these fishes as "altogether one of the oddest creatures in the teeming variety of the fish world." In contrast to other anglerfishes, the bioluminescent lure of Thaumatichthys is located inside its cavernous mouth. They are worldwide in distribution and are ambush predators living near the ocean floor.
Leptochilichthys is a genus of fishes containing four species. Leptochilichthys is the only genus in the former family Leptochilichthyidae but is now included within the broader family Alepocephalidae.
Borsonella coronadoi is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.
Alepocephalus is a genus of slickheads found in all oceans.
Bathyprion danae, the fangtooth smooth-head, is a species of slickhead found in deep waters of the Atlantic and Pacific Oceans. It is in the monotypic genus Bathyprion.
The belligerent sculpin, or flathead sculpin, is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This species occurs in the northern Pacific Ocean.
Albert Eide Parr was an American marine biologist, zoologist and oceanographer. He was the director of the American Museum of Natural History from 1942 to 1959. Parrosaurus missouriensis, a species of plant-eating dinosaur, is named after him.
Acromycter perturbator is an eel in the family Congridae. It was described by Albert Eide Parr in 1932, originally under the genus Ariosoma. It is a marine, deep water-dwelling eel which is known from the northwestern and western central Atlantic Ocean, including the Bahamas, the United States, and Jamaica. It dwells at a depth range of 1299–1318 metres.
The Sailfin eel is an eel in the family Ophichthidae. It was described by Raymond Carroll Osburn and John Treadwell Nichols in 1916, originally under the genus Letharchus. It is a marine, tropical eel which is known from the eastern central Pacific Ocean, including Costa Rica, Mexico, and Panama. It is known to dwell at a depth of 35 metres (115 ft), and inhabits rock and sand sediments. Males can reach a maximum total length of 81 centimetres (32 in).
Macolor macularis, the midnight snapper, midnight seaperch or black and white snapper, is a species of marine ray-finned fish, a snapper belonging to the family Lutjanidae. It is native to the Indian and western Pacific Oceans.
Cylichnium is a genus of very small sea snails, unassigned in a family in the order Cephalaspidea.
Lloyd's slickhead is a species of fish in the family Alepocephalidae (slickheads). The fish is found in the Indo-West Pacific: on Indian Ocean ridges, in the Arabian Sea and the South China Sea. This species reaches a length of 50 cm (20 in).
