Herring are forage fish, mostly belonging to the family of Clupeidae.
The Irrawaddy dolphin is a euryhaline species of oceanic dolphin found in scattered subpopulations near sea coasts and in estuaries and rivers in parts of the Bay of Bengal and Southeast Asia. It closely resembles the Australian snubfin dolphin, which was not described as a separate species until 2005. It has a slate blue to a slate gray color. Although found in much of the riverine and marine zones of South and Southeast Asia, the only concentrated lagoon populations are found in Chilika Lake in Odisha, India and Songkhla Lake in southern Thailand.
The snubfin dolphins (Orcaella) are a genus of cetaceans containing two members: the Irrawaddy dolphin and the Australian snubfin dolphin. The genus was long believed to be monotypic with the only species being the Irrawaddy dolphin; however, in 2005, supposed Irrawaddy dolphin populations inhabiting the Australian/New Guinean regions were found to be significantly different and were declared a separate new species named the Australian snubfin dolphin.
Caiman is a genus of caimans within the alligatorid subfamily Caimaninae. They inhabit Central and South America. They are relatively small sized crocodilians, with all species reaching lengths of only a couple of meters and weighing 6 to 40 kg on average.
The red-legged kittiwake is a seabird species in the gull family Laridae. It breeds in the Pribilof Islands, Bogoslof Island, and Buldir Island in the Bering Sea off the coast of Alaska, and the Commander Islands, Russia, and spends the winter at sea.
The lemon shark is a species of shark from the family Carcharhinidae and is classified as a Vulnerable species by the International Union for the Conservation of Nature. Lemon sharks can grow to 3.4 metres (11 ft) in length. They are often found in shallow subtropical waters and are known to inhabit and return to specific nursery sites for breeding. Often feeding at night, these sharks use electroreceptors to find their main source of prey, fish. Lemon sharks enjoy the many benefits of group living such as enhanced communication, courtship, predatory behavior, and protection. This species of shark gives birth to live young, and the females are polyandrous and have a biennial reproductive cycle. Lemon sharks are not thought to be a large threat to humans; there have been 10 recorded bites, none of which were life-threatening. The lemon shark's life span is unknown, but the average shark is 25 to 30 years old. The oldest recorded lemon shark in captivity died in 2023 at the age of 40 years.
Kittlitz's murrelet is a small alcid found in the waters off Alaska and Eastern Siberia. This near threatened species is, like the closely related marbled murrelet, unusual for seabirds in not being colonial, nesting instead in isolated locations on mountain tops, where the nests were known to Native Americans for many years before skeptical ornithologists described and photographed them. It is a poorly known and little studied species, although concern over its status and that of the closely related marbled murrelet has led to a recent increase in research.
The shortnose sucker is a rare species of fish in the family Catostomidae, the suckers. This fish is native to southern Oregon and northern California in the United States. It is a federally listed endangered species of the United States.
The redtail catfish, Phractocephalus hemioliopterus, is a pimelodid (long-whiskered) catfish. In Venezuela, it is known as cajaro, in Guyana, it is known as a banana catfish, and in Brazil, it is known as pirarara, stemming from the Tupi language words pirá and arara. It is the only extant species of the genus Phractocephalus. This fish is common in the aquarium trade, although its massive adult size makes it unsuitable for all but the largest aquariums. They feed on fish, crustaceans and fallen fruits. They are not evaluated by IUCN.
The weebill is a species of bird in the family Acanthizidae. It is an insectivorous passerine that is found throughout mainland Australia. At 8 to 9 cm long, it is Australia's smallest bird. It was originally described by John Gould in 1838, and four subspecies are recognised. The weebill's plumage is nondescript, with olive-grey upperparts and paler, more yellowish underparts. It grades from more brownish plumage in the southern regions of Australia to more yellow in tropical areas.
The sicklefin lemon shark or sharptooth lemon shark is a species of requiem shark belonging to the family Carcharhinidae, widely distributed in the tropical waters of the Indo-Pacific. It is closely related to the better-known lemon shark (N. brevirostris) of the Americas; the two species are almost identical in appearance, both being stout-bodied sharks with broad heads, two dorsal fins of nearly equal size, and a plain yellow-tinged coloration. As its common name suggests, the sicklefin lemon shark differs from its American counterpart in having more falcate (sickle-shaped) fins. This large species grows up to 3.8 m (12 ft) long. It generally inhabits water less than 92 m (302 ft) deep in a variety of habitats, from mangrove estuaries to coral reefs.
The Pacific bluefin tuna is a predatory species of tuna found widely in the northern Pacific Ocean, but it is migratory and also recorded as a visitor to the south Pacific.
The Himalayan swiftlet is a small swift. It is a common colonial breeder in the Himalayas and Southeast Asia. Some populations are migratory.
The Lost River sucker is a species of ray-finned fish in the family Catostomidae. It is the only living member of the genus Deltistes. It is found only in California and Oregon. Its population is much reduced from historical numbers for a number of reasons. It is federally listed as an endangered species of the United States. This species is known as the C'waam by the Klamath Tribes, a Native American nation.
The shortnose guitarfish is a species of fish in the Trygonorrhinidae family found in the southwest Atlantic in coastal parts near sandy sea floors of southern Brazil, through Uruguay, to northeast Argentina. It reaches a length of 66 cm (2.17 ft). Their diet consist of Crabs, worms, clams and small fishes. The guitarfish has become critically endangered because of the rapid decline caused by overfishing.
Pao baileyi, the hairy pufferfish, is a species of pufferfish usually found in the rocky habitats, including rapids, of the Mekong mainstream and its larger tropical freshwater tributaries.
Naso brevirostris, also known as the short-nosed unicornfish, spotted unicornfish, brown unicornfish, lined unicornfish, longnose surgeonfish, palefin unicornfish, paletail unicornfish, shorthorned unicornfish or shortsnouted unicornfish, is a species of marine ray-finned fish belonging to the family Acanthuridae, the surgeonfishes, unicornfishes and tangs. It occurs in the Indian and western Pacific Oceans.
The Atlantic needlefish is a common demersal needlefish species common in marinas and other areas with minimal currents. Its extremely long jaw and body set this fish apart from other predators. Atlantic needlefish are found from Maine to Brazil and have been known to venture into fresh water for short periods.
Pao is a genus of mostly freshwater pufferfish with one species also occurring in brackish water. They are found in Southeast Asia. Until 2013, its species were generally placed in Tetraodon.
Pao ocellaris is a species of pufferfish in the family Tetraodontidae. It is a tropical freshwater species native to Asia, where it is known from Mae Klong in Thailand to the lower Mekong basin in Cambodia, Vietnam, and Laos. It was included in the genus Tetraodon until 2013.
