Alcathous is a monotypic genus containing the species Alcathous fecialis: a fulgorid planthopper, in the subfamily Amyclinae and found in southern India.
It is predominantly brown with dark markings. Its snout curves slightly upward, and its wings are about 3 cm long and hide its short abdomen. From its eyes to the tip of its abdomen, A. fecialis is about 1.2 cm long with a 0.3 cm snout. [1]
Alcathous was the name of several people in Greek mythology:
A sawshark or saw shark is a member of a shark order bearing a unique long, saw-like rostrum edged with sharp teeth, which they use to slash and disable their prey. There are eight species within the Pristiophoriformes, including the longnose or common sawshark, shortnose sawshark, Japanese sawshark, Bahamas sawshark, sixgill sawshark, African dwarf sawshark, Lana's sawshark and the tropical sawshark.
The gharial, also known as gavial or fish-eating crocodile, is a crocodilian in the family Gavialidae and among the longest of all living crocodilians. Mature females are 2.6 to 4.5 m long, and males 3 to 6 m. Adult males have a distinct boss at the end of the snout, which resembles an earthenware pot known as a ghara, hence the name "gharial". The gharial is well adapted to catching fish because of its long, narrow snout and 110 sharp, interlocking teeth.
Lycodon aulicus, commonly known as the Indian wolf snake or common wolf snake, is a species of nonvenomous snake found in South Asia and Southeast Asia. Early naturalists have suggested its resemblance to the venomous common krait as an instance of Batesian mimicry.
The checkered keelback, also known commonly as the Asiatic water snake, is a common species in the subfamily Natricinae of the family Colubridae. The species is endemic to Asia. It is non-venomous.
The spiny-back eel, Notacanthus sexspinis, is a deep-sea spiny eel of the genus Notacanthus, found in all the Southern Hemisphere oceans at depths between 500 and 1,000 m. The length of this fish is up to 60 cm (24 in).
Catopsilia pomona, the common emigrant or lemon emigrant, is a medium-sized pierid butterfly found in Asia and parts of Australia. The species gets its name from its habit of migration. Some early authors considered them as two distinct species Catopsilia crocale and Catopsilia pomona.
The taillight shark is a little-known species of shark in the family Dalatiidae and the only member of its genus. It is known from only four specimens collected from deep oceanic waters in the southern Atlantic Ocean and Pacific Ocean. A small shark with a laterally compressed body and a bulbous snout, this species has unusual adaptations that indicate a specialized lifestyle: its pectoral fins are paddle-like and may be used for propulsion, unlike other sharks and it has a pouch-like gland on its abdomen that emits clouds of luminescent blue fluid. This shark is likely aplacental viviparous and a formidable predator for its size.
The ornate dogfish is dogfish shark which is not widely known. It is found in deepwater on the continental slopes of the Indian Ocean, the Arabian Sea and the Bay of Bengal, at depths between 520 and 1,260 m. Its length is up to 30 cm, and its reproduction is ovoviviparous.
The smalleye pygmy shark is a little-known species of squaliform shark in the family Dalatiidae, found in water 150–2,000 m (490–6,560 ft) deep near Japan, the Philippines, and Australia. It migrates vertically daily, spending the day in deep water and the night in shallower water. One of the smallest shark species, the smalleye pygmy shark is known to reach only 22 cm (8.7 in) long. It has a blackish, spindle-shaped body with relatively small eyes, and a spine preceding the first dorsal fin, but not the second. Bioluminescent photophores occur on its underside, which may serve to disguise its silhouette from predators. This species feeds on small squid, krill, shrimp, and bony fishes. It is aplacental viviparous. The International Union for Conservation of Nature has assessed it as Least Concern, citing its wide distribution and lack of threat from fisheries.
The quagga catshark is a species of catshark, belonging to the family Scyliorhinidae. A small, slim-bodied shark reaching 37 cm (15 in) in length, it has a distinctive color pattern of narrow, dark brown vertical bars, which resemble those of the quagga. Its head is short and flattened, with a pointed snout tip that is not upturned.
The bristly catshark 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.
The longhead catshark or smoothbelly catshark is a species of catshark, family Scyliorhinidae, with a patchy distribution in the Indo-Pacific from Mozambique to southern Japan to northern Australia. It is found in water between 500 and 1,140 m deep. This species grows to 59 cm (23 in) long and is characterized by its extremely long and narrow snout, short abdomen, and long anal and caudal fins. In addition, a large area of the anterior ventral portion of its body lacks dermal denticles. The longhead catshark is oviparous and the only known cartilaginous fish that is normally hermaphroditic, with the majority of individuals having both the functional reproductive organs of one sex and the undeveloped reproductive organs of the opposite sex.
The green lanternshark is a species of dogfish shark in the family Etmopteridae, found in the western central Atlantic Ocean. This species usually occurs on the upper continental slope below a depth of 350 m (1,150 ft). Reaching 26 cm (10 in) in length, the green lanternshark has a slender body with a long, thin tail and low, conical dermal denticles on its flanks. It is dark brown or gray with ventral black coloration, which contain light-emitting photophores that may serve a cryptic and/or social function. Green lanternsharks are thought to be gregarious and may attack their prey, squid and octopus often larger than themselves, in packs. Reproduction is aplacental viviparous, with females giving birth to litters of one to three young. This relatively common shark is an occasional, valueless bycatch of commercial fisheries; currently it does not appear to be significantly threatened by human activities.
The Arabian carpetshark is a species of carpet shark in the family Hemiscylliidae, inhabiting coral reefs and other shallow coastal habitats from the Persian Gulf to India. Reaching 78 cm (31 in) long, this shark is characterized by a slender, plain brown body, and by two dorsal fins with straight trailing margins and the second smaller but longer-based than the first. The Arabian carpetshark feeds on bony fishes and invertebrates. Reproduction is oviparous with an annual cycle; females deposit egg capsules four at a time and the young hatch after 70–80 days. This small shark is often captured as bycatch but rarely used by humans. It has been assessed as Near Threatened by the International Union for Conservation of Nature (IUCN), as there is increasing fishing pressure and habitat degradation within its range. It does well in aquariums and has been bred in captivity.
Lasiancistrus is a genus of suckermouth armored catfishes. They are native to South America and Panama.
The alligator pipefish or double-ended pipefish is a species of fish in the family Syngnathidae and is the only species in the monotypic genus Syngnathoides. It is found in shallow water in the tropical and subtropical Indo-Pacific, its range extending from East Africa to northern Australia. This fish lives in habitats of seagrass and seaweed, and hides by positioning itself vertically with its head down amidst the similar-coloured fronds of vegetation. The elongated, well-camouflaged body can reach 29 cm (11 in) in length. It feeds by sucking up its prey.
2241 Alcathous is a large Jupiter trojan from the Trojan camp, approximately 115 kilometers in diameter. It was discovered on 22 November 1979, by American astronomer Charles Kowal at the Palomar Observatory in southern California, United States. The dark D-type asteroid belongs to the 20 largest Jupiter trojans and has a rotation period of 7.7 hours. It was named after Alcathous from Greek mythology.
Formiscurra indicus is a species of planthopper in the family Caliscelidae found in southern India. A related species, Formiscurra atlas occurs in southwestern Ethiopia. Like others of its family they have short wings, suck plant sap and escape by leaping. The species shows great sexual dimorphism. The male of this half centimeter-long insect has an enlarged lobe in front of its head, the frons or metope, giving it an ant-like appearance. Females do not have such an enlarged structure but have a slightly long snout and differ slightly in body shape. The species is found mainly on low vegetation in open scrub and grass habitats.
Ammodytes americanus, also known as American sand lance, American sand eel, and sand launce, is a small fish in the family Ammodytidae. First described by James Ellsworth De Kay in 1842, it is widespread in the western North Atlantic. Like all sand lances, it has a long, thin body with a pointed snout; mature fish typically range from 4 to 6 in in length, though some may reach 7 in (18 cm). Its back is greenish-brown, while its sides and abdomen are silvery. It has a long, low dorsal fin which extends along most of its back, folding into a groove at the fin's base when not in use. Its anal fin is roughly the same height as the dorsal fin, and extends over the posterior third of the fish's body. Its pectoral fins are small, and its caudal fin is forked. Its mouth is large and toothless, with a lower jaw that extends well beyond the upper. It typically travels in large schools, spending most of its time relatively near the water surface. It feeds primarily on plankton, though it is known to take small clams and snails from the sea floor, presumably when plankton is scarce. Towards dusk, schools of A. americanus bury themselves in sand, typically from 1 to 6 in below the sand's surface close to the water's edge; they avoid rocky areas. They do this to avoid being detected by night-hunting species such as bluefish and stripers.
