Gasterosteus nipponicus is a species of ray-finned fish belonging to the family Gasterosteidae, the sticklebacks. This species is found in the northwestern Pacific Ocean.
Gasterosteus nipponicus first formally described in 2014 by Masahito Higuchi, Harumi Sakai and Akira Goto with the type locality given Usujiri, Minamikayabe, Hokkaido in Japan. [2] Higachi and Goto had previously identified a lineage of three-spined sticklebacks (G. aculateus) from Japan which had substantial differences from the other lineages, both morphological and genetic, and which genetic studies showed rarely hybridised with sympatric populations of threes-spined sticklebacks. [3]
Gasterosteus nipponicus differs from the three-spined stickleback in that the lateral plates are complete and that they suddenly reduce in size over the anus, the depth of lateral plate over the anus less than 60% of the depth of the deepest plate. In addition the caudal keels are thin and membrane-like. This species has a maximum published standard length of 7.2 cm (2.8 in) in males and 7.9 cm (3.1 in) in males. [4]
Gasterosteus nipponicus is found in the northwestern Pacific Ocean. Here it occurs in along the Sea of Japan coats of Japan from Kyushu to Hokkaido, from Chiba Prefecture to Hokkaido on the eastern coast of Japan, along the northern coast of Hokkaido on the Sea of Okhotsk. It is also found along the southern and eastern coasts of the Korean Peninsula and north to Sakhalin. This is a benthopelagic fish which can be found in marine, brackish and fresh waters. [4]
Gasterosteoidei is a suborder of ray-finned fishes that includes the sticklebacks and relatives, the 5th edition of Fishes of the World classifies this suborder within the order Scorpaeniformes.
The sticklebacks are a family of ray-finned fishes, the Gasterosteidae which have a Holarctic distribution in fresh, brackish and marine waters. They were thought to be related to the pipefish and seahorses but are now thought to be more closely related to the eelpouts and sculpins.
The three-spined stickleback is a fish native to most inland and coastal waters north of 30°N. It has long been a subject of scientific study for many reasons. It shows great morphological variation throughout its range, ideal for questions about evolution and population genetics. Many populations are anadromous and very tolerant of changes in salinity, a subject of interest to physiologists. It displays elaborate breeding behavior and it can be social making it a popular subject of inquiry in fish ethology and behavioral ecology. Its antipredator adaptations, host-parasite interactions, sensory physiology, reproductive physiology, and endocrinology have also been much studied. Facilitating these studies is the fact that the three-spined stickleback is easy to find in nature and easy to keep in aquaria.
The red lionfish is a venomous coral reef fish in the family Scorpaenidae, order Scorpaeniformes. It is mainly native to the Indo-Pacific region, but has become an invasive species in the Caribbean Sea, as well as along the East Coast of the United States and East Mediterranean and also found in Brazil at Fernando de Noronha.
The ninespine stickleback, also called the ten-spined stickleback, is a freshwater species of fish in the family Gasterosteidae that inhabits temperate waters. It is widely but locally distributed throughout Eurasia and North America. Despite its name, the number of spines can vary from 8 to 12.
The brook stickleback is a small freshwater fish that is distributed across the US and Canada. It grows to a length of about 2 inches. It occupies the northern part of the eastern United States, as well as the southern half of Canada. Small populations are scattered throughout the Mississippi-Great Lakes basin extending to Colorado, New Mexico, Kentucky, Tennessee, etc., though some of these areas are not native to the species. This small fish inhabits clear, cool streams and lakes. They eat small invertebrates, algae, insect larvae, and occasionally their own eggs. They are also preyed upon by smallmouth bass and northern pike. Feedin time is usually dawn and sunset. The brook stickleback does have active competition mostly from minnows, but feeding times are different, along with diet. Spawning occurs in midsummer. Males secure a territory, build a nest, and mate with females. Males provide protection for the eggs, ward off predators, and usually die later in the season. This is considered an annual species. The nests are built out of aquatic grasses. Though the brook stickleback is not considered a threatened species, deforesting and changing waters are altering ecosystems of the species. Harvesting of trees around riparian environments is having a large effect of the stream ecosystem where the brook stickleback resides.
The Hong Kong grouper is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in eastern and southeastern Asian waters of the Western Pacific Ocean. Its natural habitats are shallow seas and coral reefs.

It is found in Australia, Cocos (Keeling) Islands, French Polynesia, Hong Kong, India, Indonesia, Japan, the Philippines, Singapore, Taiwan, Thailand, and Vietnam. Its natural habitat is shallow seas. It is threatened by habitat loss.
Astropyga radiata, the red urchin, fire urchin, false fire urchin or blue-spotted urchin, is a species of sea urchin in the family Diadematidae. It is a large species with long spines and is found in the tropical Indo-Pacific region. It was first described in 1778 by the German naturalist Nathaniel Gottfried Leske.

Freshwater demersal fish, up to 5.5 cm (2.2 in) length. Habits small streams, where feeds on aquatic insects and other invertebrates. This taxon is regarded by some authorities as a synonym of the three-spined stickleback, and others treat it as a subspecies of the three-spined stickleback, G. a. microcephalus.
Despeciation is the loss of a unique species of animal due to its combining with another previously distinct species. It is the opposite of speciation and is much more rare. It is similar to extinction in that there is a loss of a unique species but without the associated loss of a biological lineage. Despeciation has been noted in species of butterflies, sunflowers, mosquitoes, fish, wolves, and even humans.
