Rhinoceros Iguana
The rhinoceros iguana (''Cyclura cornuta'') is an endangered species of iguana that is endemic to the Caribbean island of Hispaniola (shared by Haiti and the Dominican Republic) and its surrounding islands. A large lizard, they vary in length from , and skin colours range from a steely grey to a dark green and even brown. Their name derives from the bony-plated pseudo-horn or outgrowth which resembles the horn of a rhinoceros on the iguana's snout. It is known to coexist with the Ricord's iguana (''C. ricordii''); the two species are the only taxa of rock iguana to do so. Taxonomy The rhinoceros iguana is a species of lizard belonging to the genus ''Cyclura''. The rhinoceros iguana's specific name, ''cornuta'', is the feminine form of the Latin adjective ''cornutus'', meaning "horned" and refers to the horned projections on the snouts of males of the species. The species was first identified by Pierre Joseph Bonnaterre in 1789. In addition to the nominate race (''C. c. cornut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedernales Province
Pedernales (; ) is the southernmost province of the Dominican Republic, including the offshore island of Isla Beata. It was split from Barahona in 1957. Of its 2,074.53 km2, 1374 km2 belong to the Jaragua National Park. A third of its population is of Haitian origin, the highest ratio within the country. The capital of the province, Pedernales, was originally called Juan López, who was a Spanish inhabitant who had settled in the area around the 19th century. The province was called Pedernales after the river located on the border with Haiti, in which flint is abundant. The indigenous people of the Dominican Republic, the Taíno, used them to make sharp tools, such as axes and arrowheads. Geography The province of Pedernales is located in the southwest of the Dominican Republic, sharing its borders with the neighboring Haiti. It is located 330 km (kilometers) from Santo Domingo, the Dominican capital. It is part of the region called Enriquillo, and it is the se ...

Pierre Joseph Bonnaterre
Abbé Pierre Joseph Bonnaterre (1752, Aveyron – 20 September 1804, Saint-Geniez-d'Olt) was a French zoologist who contributed sections on cetaceans, mammals, birds, reptiles, amphibians, fish, and insects to the '' Tableau encyclopédique et méthodique''. He is also notable as the first scientist to study the feral child A feral child (also called wild child) is a young individual who has lived isolated from human contact from a very young age, with little or no experience of human care, social behavior, or language. The term is used to refer to children who h ... Victor of Aveyron. Bonnaterre is credited with identifying about 25 new species of fish, and assembled illustrations of about 400 in his encyclopedia work of book. He was the first scientist to study Victor, the wild child of Aveyron, whose life inspired François Truffaut for his film '' The Wild Child''.

Étang Saumâtre
Étang Saumâtre (English: ''brackish pond'') is the largest lake in Haiti and the second largest lake in the Dominican Republic and Hispaniola, after Lake Enriquillo. It is also known as Lake Azuéi (''Lac Azuéi''); its Taíno name was ''Yainagua''. Unlike its hypersaline neighbor, Étang Saumâtre is a brackish water lake. It lies east of Port-au-Prince on the fertile Plaine du Cul-de-Sac. The lake supports over 100 species of waterfowl, American flamingos (''Phoenicopterus ruber''), American crocodiles (''Crocodylus acutus''), and several other fauna found nowhere else in Haiti. The color of the lake is an intense shade of blue, and it is skirted by brush and cacti. Geography Étang Saumâtre is located on the arid part of the valley Cul-de-Sac, east of Port-au-Prince in the Ouest department. Its eastern side is part of the border between Haiti and the Dominican Republic; the Dominican city of Jimaní is less than 1 km from the southeast end of the lake. The la ...

Beata Island
Beata Island ( es, Isla Beata) is a small island on the Caribbean Sea, located southwest from Cape Beata. Some southwest of it lies the smaller Alto Velo Island. It is politically part of the Dominican Republic, and is roughly triangle-shaped and fairly flat, with an approximate area of . History Beata Island was discovered by Europeans during the second voyage of Christopher Columbus in 1494. Originally populated by Taíno natives, the island became a colonial asset of the Captaincy General of Santo Domingo and the greater Spanish Empire. The island was the site of various military engagements between the Spanish and roving pirates. Geography The landscape is somewhat varied, with mangrove swamps on parts of the North shore, sandy coves and beaches on the west coast. Most of the interior of the island is covered by various subtypes of xeric semi-deciduous limestone forests. Geologically, the island is basically made out of limestone, the erosion of which causes very jagge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pheromones
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are ''alarm pheromones'', ''food trail pheromones'', ''sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek φερω ''pheroo'' ('I carry') and ὁρμων ''hormon'' ('stimulating'). Pheromones ...

Femoral Pore
Femoral pores are a part of a holocrine secretory gland found on the inside of the thighs of certain lizards and amphisbaenians which releases pheromones to attract mates or mark territory. In certain species only the male has these pores and in other species, both sexes have them, with the male's being larger. Femoral pores appear as a series of pits or holes within a row of scales on the ventral portion of the animal's thigh. Femoral pores are present in all genera in the families Cordylidae, Crotaphytidae, Hoplocercidae, Iguanidae, Phrynosomatidae, and Xantusiidae. They are absent in all genera in the Anguidae, Chamaeleonidae, Dibamidae, Helodermatidae, Scincidae, Xenosauridae, and Varanidae families. They are present in other lizards and amphisbaenians quite variably, some geckoes, '' Phelsuma'', for example have these pores, others in the same family do not. In the desert iguana (''Dipsosaurus dorsalis''), the waxy lipids released from the femoral pores abs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsum (biology)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of ana ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated ...

Dewlap
A dewlap is a longitudinal flap of skin or similar flesh that hangs beneath the lower jaw or neck of many vertebrates. More loosely, it can be various similar structures in the neck area, such as those caused by a double chin or the submandibular vocal sac of a frog. More generally, it can be any hanging mass of skin, such as a fold of loose skin on an elderly person's neck, or the wattle of a bird. Dewlaps can be considered as a ''caruncle'', defined as "a small, fleshy excrescence that is a normal part of an animal's anatomy". Etymology The word is first attested in the mid 1300s as ''dewelappe'' ("fold of skin that hangs from the throat of oxen and kine"), from ''lappe'' ("loose piece", from Old English ), but the first element ''*dew(e)-'' is of nebulous origin and meaning; it probably was altered by folk etymology with " dew". Old English had ''fræt-læppa'' in the aforementioned sense (and Middle English ''fresh-lappe''). There also seems to be a cognate to Danish di ...
