Jacques Pellegrin
Jacques Pellegrin (12 June 1873 – 12 August 1944) was a French zoology, zoologist. Biography Pellegrin was born in Paris on 12 June 1873. He worked under zoologist Léon Vaillant (chair of reptiles and fishes) at the ''Muséum national d'histoire naturelle''. From 1897, Pellegrin served as ''préparateur'' at the museum. He obtained doctorates in medicine (1899) and science (1904), and in 1908 was named as an assistant director. After many missions abroad, he became sub-director of the museum in 1937, and replaced Louis Roule (1861–1942) as the chairperson of herpetology and ichthyology. He published over 600 scientific books and articles and scientifically described around 350 new species. He named a number of fishes from the family Cichlidae, such as the genera ''Astatoreochromis'', ''Astatotilapia'', ''Boulengerochromis'', ''Lepidiolamprologus'', ''Nanochromis'' and ''Ophthalmotilapia''. Pellegrin fought with the French Resistance during World War II. He was killed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Fish
An electric fish is any fish that can Bioelectrogenesis, generate electric fields, whether to sense things around them, for defence, or to stun prey. Most fish able to produce shocks are also electroreceptive, meaning that they can sense electric fields. The only exception is the Uranoscopidae, stargazer family (Uranoscopidae). Electric fish, although a small minority of all fishes, include both oceanic and freshwater species, and both cartilaginous and bony fishes. Electric fish produce their electrical fields from an Electric organ (biology), electric organ. This is made up of electrocytes, modified muscle or nerve cells, specialized for producing strong electric fields, used to locate prey, for Anti-predator adaptation, defence against predators, and for Signalling theory, signalling, such as in courtship. Electric organ discharges are two types, pulse and wave, and vary both by species and by function. Electric fish have evolved many specialised behaviours. The predatory Cla ...

Mormyridae
The Mormyridae, sometimes called "elephantfish" (more properly freshwater elephantfish), are a superfamily of weakly electric fish in the order Osteoglossiformes native to Africa. It is by far the largest family in the order, with around 200 species. Members of the family can be popular, if challenging, aquarium species. These fish have a large brain size and unusually high intelligence. They are not to be confused with the marine and brackish-water callorhinchid elephantfish (family Callorhinchidae) of Southern Hemisphere oceans. Description and biology The elephantfish are a diverse family, with a wide range of different sizes and shapes. The smallest are just in adult length, while the largest reach up to . They do, however, have a number of unique features in common. Firstly, their cerebellum is greatly enlarged, enabling them to interpret complex bio-electrical signals, and to the large size of the valve. Secondly, an auditory vesicle (a small bladder) is present insid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Komoé River
The Komoé River or Comoé River is a river in West Africa. The river originates on the Sikasso Plateau of Burkina Faso, flows through the Cascades de Karfiguéla, forms a short section of the border between Burkina Faso and Ivory Coast before entering Ivory Coast. It serves as the major drainage for the northeastern portion of that country before emptying into the Atlantic. The banks of the Komoé are shaded by riparian forests along most of its length, providing an important habitat for wildlife and a source of agricultural water. Where reliable floodplains form in Ivory Coast, rice may be grown. A portion of the river in northern Ivory Coast is the source of the vegetative richness that earned that area a UNESCO World Heritage Site designation, Comoé National Park. Course The Komoé River is approximately 759 km long. It rises on the Sikasso Plateau and in the Sindou Hills flowing south over several cataracts with several falls including the "Chutes de la Komoé" a ...

Bandama River
The Bandama River is the longest river in Ivory Coast with a length of some 800 kilometers. The south-flowing river is fed by the Marahoué, Solomougou, Kan and Nzi rivers and empties into the Tagba Lagoon and the Gulf of Guinea. The Bandama flows through Lake Kossou, a large artificial lake created in 1973 by the construction of the Kossou Dam at Kossou.

Sassandra River
The Sassandra River is a river of western Ivory Coast in West Africa. It is formed by the confluence of the Tienba River, which originates in the highlands of north-western Ivory Coast, and the Gouan River (also known as the Bafing Sud River), which originates to the west in the highlands of Guinea. The Sassandra flows south-southeast to empty into the Gulf of Guinea on the Atlantic Ocean. The Buyo Dam was constructed across the middle stretch of the river in 1980, just below the confluence with the Nzo River, to create the reservoir called Lake Buyo. The Davo River joins the Sassandra just before it meets the sea. The port town of Sassandra lies on the seacoast where the river meets the sea. The Sassandra and its tributaries flow through terrestrial ecoregion An ecoregion (ecological region) is an ecological and geographic area that exists on multiple different levels, defined by type, quality, and quantity of environmental resources.

Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conse ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...
