Its vernacular names include cowfish, jollytail, common jollytail, eel gudgeon, inaka, native trout, pulangi, puye, slippery tarki, spotted minnow, Falklands minnow and whitebait.

Leonard Blomefield
Leonard Jenyns (25 May 1800 – 1 September 1893) was an English clergyman, author and naturalist. He was forced to take on the name Leonard Blomefield to receive an inheritance. He is chiefly remembered for his detailed phenology observations of the times of year at which events in natural history occurred. Personal life Jenyns was born in 1800 at No. 85 Pall Mall, London, the home of his maternal grandfather. He was the youngest son of George Leonard Jenyns of Bottisham Hall, Cambridgeshire, a magistrate, landowner and a prebendary of Ely Cathedral. His mother Mary (1763–1832) was the daughter of William Heberden (1710–1801). His father had inherited the Bottisham Hall property on the death of his distant cousin Soame Jenyns (1704–1787). By 1812, Jenyns began to study natural history encouraged by his great uncle. He went to Eton in 1813 where he read, and was inspired by Gilbert White's '' Natural History of Selborne''. In 1817 Jenyns was introduced to Sir Jose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as Estuary, estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, reef, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shoaling And Schooling
In biology, any group of fish that stay together for social reasons are shoaling, and if the group is swimming in the same direction in a coordinated manner, they are schooling. In common usage, the terms are sometimes used rather loosely. About one quarter of fish species shoal all their lives, and about one half shoal for part of their lives. Fish derive many benefits from shoaling behaviour including defence against predators (through better predator detection and by diluting the chance of individual capture), enhanced foraging success, and higher success in finding a mate. It is also likely that fish benefit from shoal membership through increased hydrodynamic efficiency. Fish use many traits to choose shoalmates. Generally they prefer larger shoals, shoalmates of their own species, shoalmates similar in size and appearance to themselves, healthy fish, and kin (when recognized). The oddity effect posits that any shoal member that stands out in appearance will be preferen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
