It was bred recently in the Dehiwala Zoological Gardens.
WThe dwarf lanternshark is a little-known species of dogfish shark in the family Etmopteridae and is the smallest shark in the world, reaching a maximum known length of 20 cm (7.9 in). It is known to be present only on the upper continental slopes off Colombia and Venezuela, at a depth of 283–439 m (928–1,440 ft). This species can be identified by its small size at maturity, long flattened head, and pattern of black ventral markings and a mid-dorsal line. Like other members of its genus, it is capable of producing light from a distinctive array of photophores. Reproduction is aplacental viviparous, with females gestating two or three young at a time. The dwarf lanternshark is not significant to commercial fisheries, but could be threatened by mortality from bycatch; the degree of impact from human activities on its population is unknown.
WThe eastern school whiting, Sillago flindersi, is a species of benthic marine fish of the smelt-whiting family Sillaginidae.

Eastern school whiting prey on various crustaceans and polychaete worms, with the diet varying seasonally and throughout the range of the species. Eastern school whiting reproduce in the deeper waters twice a year, releasing up to 110,000 eggs during a season.
WFedorov's catshark is a catshark of the family Scyliorhinidae. This shark has oviparous reproduction. This is a very poorly known species, with less than 30 specimens reported in the scientific literature. Almost nothing is known of its biology. This species may be endemic to northern Japanese waters, where it is taken in water around 1,200 m deep. However, accurate identification of Apristurus species is particularly difficult, and further research is required to determine its geographical and bathymetrical distribution.

WParamormyrops hopkinsi (Taverne and Thys van den Audenaerde, 1985) is a species of freshwater electric fish. It was discovered in the Ivindo River in Gabon, in west-Central Africa by Dr. Carl D. Hopkins of Cornell University. It is distributed throughout the Ivindo River basin of Gabon and the Ntem River basin of Cameroon. Described originally as a Brienomyrus in 1985 it was transferred to Paramormyrops in 2007. The electric discharge has two phases: a head-positive phase followed by a head-negative phase. The mean duration of the EOD is 2.8 ms for females, 2.96 for males. The Fourier transform of the EOD peaks at 536 Hz for females, 468 for males. Both male and female EODs have a head-negative voltage bump about 5 to 6 ms after the main head positive phase (arrows).
WParioglossus marginalis, also known as the blackmargin dartfish, is a species of dartfish native to the brackish waters of the coast of New South Wales, Australia and around the northern part of the North Island and Great Barrier Island in New Zealand, This species may be an introduced species in New Zealand, being brought from Australia in ship's ballast water. This species can reach a length of 3.3 centimetres (1.3 in) SL. It is thought by some workers that Parioglossus neoclaedonicus from New Caledonia may be a synonym of P. marginalis and that the Caroline Islands species Parioglossus verticalis, which is known form just a single specimen, may also be synonymous with this species. To resolve these taxonomic uncertainties molecular studies will be required.

It is endemic to Papua New Guinea where it occurs in tributary streams of the Gogol River near Madang, but it has also been recorded from the middle Ramu basin. This species was described by Gerald R. Allen in n1985 and the type locality is given as "tributary of Ramu River about 3 kilometers south of Walium Village".
WThe slender whiting is a poorly known species of inshore marine fish of the smelt whiting family, Sillaginidae that has a distribution limited to the Persian Gulf only. The Slender whiting, like most sillaginids requires careful study to determine its identity, with ray and vertebrae counts as well as swim bladder morphology distinguishing features. This inshore species of fish is commonly taken by fishermen using beach seines and is sold fresh in local markets.
WThe small-eyed whiting, Sillago microps, is a poorly known species of coastal marine fish of the smelt-whiting family Sillaginidae. The species is known from only two specimens; the holotype collected by Roland McKay in 1985 from a Taipei market, both specimens of which were taken from the waters of Taiwan. Apart from a relatively small eye size, the species is hard to distinguish from other common species of sillaginid taken in the area, and may be a minor part of local fisheries.
WThe smoothtooth blacktip shark is a species of requiem shark in the family Carcharhinidae. It is known only from the type specimen caught from the Gulf of Aden, off eastern Yemen, and a handful of additional specimens caught from the Persian Gulf, off Kuwait. Reaching 1.3 m (4.3 ft) in length, this species has a stocky greenish-colored body, a short snout, and black-tipped fins. It can be distinguished from similar species by its teeth, which are narrow, erect, and smooth-edged.
WStegastes nigricans, the dusky farmerfish, is a species of damselfish found around coral reefs at a depth of one to 12 meters, in tropical climates between 30°S and 30°N. They are known for farming monocultures of algae such as cyanophores and rhodophytes.
WStegastes pelicieri, commonly known as the Mauritian gregory, is a damselfish of the family Pomacentridae. It is native to the islands of Mauritius and Réunion in the western Indian Ocean where it is found at depths between two and twenty metres. It lives on rocky reefs in areas with little coral but plenty of holes and crevices.
WThe western school whiting, also known as the banded whiting, golden whiting and bastard whiting, is a species of benthic marine fish in the smelt-whiting family Sillaginidae. The species is one of three 'school whiting' that inhabit southern Australia and share a very similar appearance. Western school whiting are known to grow to 30 cm in length and 275 g in weight, although unconfirmed reports suggest this might be an underestimate. The western school whiting is distributed along the Western Australian coast from Maud Landing in the north to Rottnest Island in the south. The species inhabits both shallow inshore environments and waters to depths of 55 m. The species is a benthic predator, taking a variety of crustaceans, molluscs and echinoderms, and shows a change in diet with age and habitat. S. vittata is a multiple spawner, reproducing between December and February once it has reached one or two years of age. Juveniles inhabit protected inshore waters, moving offshore once they reach sexual maturity. It is often found in association with other sillaginids and comprises a minor fraction of commercial whiting catches in Western Australia.
WThe whitetip weasel shark is a weasel shark of the family Hemigaleidae. Only one specimen, caught off Kosi Bay, South Africa, has been caught. That specimen was 96 cm long. In 2020, a fuzzy image believed to be this shark was obtained on the show Extinct or Alive.
