The Bean's sawtooth eel (Serrivomer beanii, also known commonly as the longfin sawpalate, the saw-tooth snipe eel, the sawtooth eel, the shortnosed snipe eel, and the stout sawpalate [2] ) is an eel in the family Nemichthyidae (snipe eels). [3] It was described by Theodore Gill and John Adam Ryder in 1883. [4] It is a marine, deep water-dwelling eel which is known from throughout the Atlantic Ocean, the Indian Ocean, and the Western Pacific Ocean, including Iceland, South Africa (the Cape and Natal), Réunion, and Australia. It dwells at a depth range of 0–5998 metres, and leads a solitary lifestyle. It migrates vertically at night. Males can reach a maximum total length of 78-80 centimetres, making it the largest sawtooth eel. [3]
The species epithet "beanii" was given in honour of American ichthyologist Tarleton Hoffman Bean. The Bean's sawtooth eel feeds primarily on benthic crustaceans including shrimps, and finfish, probably also small oreos and lanternfish. [5] Young ones may be preyed upon by the Warty oreo (Allocyttus verrucosus). [6] It is of no commercial interest to fisheries. [3]
The eel, like other sawtooth eels, has long, fine and narrow jaws with protruding teeth that are falciform and point backwards, to aid in the consumption of large prey. It has a pale, metallic blue-ish skin, delicate and without scales, which becomes translucid and gelatinous when the fish is brought to the surface. Caudal and pelvic fins are absent, the pectoral fins are falciform and small, and the dorsal and anal fins are merged in the end of the tail. The anal fin is longer than the dorsal fin. The fins are transparent, and have no true spines. During the night, it migrates vertically to feed on its prey, shrimp, lanternfishes, smaller eels, squid, and flashlight fishes.
Tarleton Hoffman Bean was an American ichthyologist.
Snipe eels are a family, Nemichthyidae, of eels that consists of nine species in three genera. They are pelagic fishes, found in every ocean, mostly at depths of 300–600 m (980–1,970 ft) but sometimes as deep as 4,000 m (13,000 ft). Depending on the species, adults may reach 1–2 m (39–79 in) in length, yet they weigh only 80–400 g (2.8–14.1 oz). They are distinguished by their very slender jaws that separate toward the tips as the upper jaw curves upward. The jaws appear similar to the beak of the bird called the snipe. Snipe eels are oviparous, and the juveniles, called Leptocephali, do not resemble the adults but have oval, leaf-shaped and transparent bodies. Different species of snipe eel have different shapes, sizes and colors. The similarly named bobtail snipe eel is actually in a different family and represented by two species, the black Cyema atrum and the bright red Neocyema erythrosoma.
The shrimp scad, is a species of widespread tropical marine fish of the jack family, Carangidae. The shrimp scad is widely distributed in the tropical and subtropical western Indian Ocean and areas of the eastern Pacific Ocean, ranging from South Africa in the west to Hawaii in the east, including Japan and Australia to the north and south. The species is commonly found on inshore reefs and sandy substrates. It has the common body profile of a scad, and may be difficult to differentiate from others in the genus Alepes. It is one of the larger scads, growing to 40 cm, but often is encountered at much smaller sizes. The shrimp scad often forms large schools, and is carnivorous, consuming a variety of crustaceans and small fish. It is of moderate importance to fisheries throughout its range.
The fangtooth moray sometimes also known as tiger moray or bird-eye conger is a moray eel of the family Muraenidae found in warmer parts of the eastern Atlantic Ocean, including the Canary Islands, Madeira and various other islands. It entered the Mediterranean Sea from the Atlantic and is now found occasionally in the eastern Basin, from Levantine waters and off Turkey, Greece, Croatia and Sicily.
The Mediterranean moray is a fish of the moray eel family. It has a long eel-like body and is found in the eastern Atlantic Ocean and Mediterranean Sea. Its bite can be dangerous to humans.
Stemonidium hypomelas is a species of deep-sea eel in the family Serrivomeridae, originally described from a 171-mm specimen taken from a depth of around 1,000 m near Niihau Island, Hawaii in 1902. It can be distinguished from the related sawtooth eels by its reduced dentition, which more resemble those of the snipe eel. It is of no significance to fisheries.
Sufflamen bursa the Lei Triggerfish is also known as the bursa triggerfish, scythe triggerfish or boomerang triggerfish, is a triggerfish from the Indo-Pacific. Its name is derived from the two markings behind its eyes that wrap around the fish similar to a Hawaiian Lei. The color of these markings changes depending on the fish's mood, in which case the colors may alter from yellow, dark brown, and black. It is a species of reef fish found in reef ecosystems in the Indo-Pacific, including Japan, Australia, and Hawaii. It occasionally makes its way into the aquarium trade.
Serrivomer is a genus of deep-sea eel in the family Serrivomeridae. It contains ten described species. Member species are distributed widely, being found in the Atlantic, Pacific and Indian Oceans. The smallest species in this genus is Serrivomer jesperseni, which has a maximum length of 40.6 cm; the largest species in this genus is Serrivomer beanii with a maximum length of 78 cm. Most members reach a maximum length of 60–70 cm,
Cancelloxus elongatus, the whiteblotched klipfish, is a species of clinid found in subtropical waters of the Atlantic Ocean along the South African coast. It prefers sandy habitats with nearby rocks at depths of from 10 to 25 metres. It can reach a maximum length of 5 centimetres (2.0 in) TL. This species preys primarily on zoobenthos.
The naked sand darter is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is found in the south-eastern United States.
Bathycongrus aequoreus is an eel in the family Congridae. It was described by Charles Henry Gilbert and Frank Cramer in 1897, originally under the genus Congermuraena.

Sphyraena putnamae, the sawtooth, chevron or military barracuda, is a species of barracuda found in all tropical seas and temperate waters of major oceans with the exception of the eastern pacific. It is found near shores in bays, turbid lagoons, and some reefs. A recognizable feature is the many dark chevron-shaped markings along its side, and its forked caudal fin. It spends its time in the shallow part of the sea off the coast, and stays closers to the surface levels of the open ocean. It can reach an age of 14 years old, and grow up to six feet long and over 100 pounds.
