Anaconda Jaune 34
Anacondas or water boas are a group of large Boinae, boas of the genus ''Eunectes''. They are a semiaquatic group of snakes found in tropical South America. Three to five extant and one extinct species are currently recognized, including one of the largest snakes in the world, ''E. murinus'', the green anaconda. Description Although the name applies to a group of snakes, it is often used to refer only to one species, in particular, the common or green anaconda (''Eunectes murinus''), which is the largest snake in the world by weight, and the second longest after the reticulated python. Origin The recent fossil record of ''Eunectes'' is relatively sparse compared to other vertebrates and other genera of snakes. The fossil record of this group is effected by an artifact called the Pull of the Recent. Fossils of recent ancestors are not known, so the living species 'pull' the historical range of the genus to the present. Etymology The name ''Eunectes'' is derived from . T ...

Geoemydidae
The Geoemydidae (formerly known as Bataguridae) are one of the largest and most diverse families in the order Testudines (turtles), with about 70 species A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), .... The family includes the Eurasian pond and river turtles and Neotropical wood turtles. Characteristics Geoemydidae are turtles of various sizes (from about in length) with often a high degree of sexual dimorphism. They usually have webbed toes, and their pelvic girdles articulate with their plastrons flexibly. Their necks are drawn back vertically. Their carapaces have 24 marginal scutes. The plastron is composed of 12 scutes and has no mesoplastron; the pectoral and abdominal scutes contact the marginal scutes. Some other features include a single articulation betwee ...

Podocnemis Unifilis
The yellow-spotted Amazon river turtle (''Podocnemis unifilis''), also known Common name, commonly as the yellow-headed sideneck turtle and the yellow-spotted river turtle, and locally as the taricaya, is one of the largest South American river turtles. ''Podocnemis unifilis'' is a type of side-necked turtles, so called because they do not pull their heads directly into their shells, but rather bend their necks sideways to tuck their heads under the rim of their shells. Side-neck turtles are classified as members of the suborder Pleurodira. Description ''Podocnemis unifilis'' is a large turtle, and can grow up to 45 cm long and weigh up to 8 kg. This species can be recognized by its black or brown oval carapace (upper shell) with distinctive low keels on the second and third scutes. Yellow spots on the side of its head give this species its common name. These spots are most prominent in juveniles and fade with age. Females can be up to twice the size of males. Distri ...

Podocnemis Expansa
The Arrau turtle (''Podocnemis expansa''), also known as the South American river turtle, giant South American turtle, giant Amazon River turtle, Arrau sideneck turtle, Amazon River turtle or simply the Arrau, is the largest of the side-neck turtles (Pleurodira) and the largest freshwater turtle in Latin America. The species primarily feeds on plant material and typically nests in large groups on beaches. Due to hunting of adults, collecting of their eggs, pollution, habitat loss, and dams, the Arrau turtle is seriously threatened. Range and habitat Arrau turtles are found in the Amazon, Orinoco and Essequibo basins in Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela and Guyana. On occasion, typically after floods, individuals turn up in Trinidad. They are found in deep rivers, ponds, freshwater lagoons and flooded forest in white-, black- and clear-water. Appearance Arrau turtles can reach up to in weight and the carapace length is up to . Most individuals are conside ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Podocnemis Erythrocephala
The red-headed Amazon side-necked turtle, red-headed river turtle or red-headed sideneck (''Podocnemis erythrocephala'') is a species of turtle in the family Podocnemididae. It is found in the Amazon basin in Brazil, Colombia, and Venezuela. Description With a size of less than , and weighing usually less than , the red-headed river turtle is considered a small one for the area, making it easily distinguishable from other local species. Identifying features of this turtle include colors ranging from dark brown to black, barbels under the chin, and a bright red strip that goes from behind its head to the Tympanum (anatomy), tympanum, which is the reason for its name, giving it the red-headed moniker. Behaviors Reproduction Females will lay anywhere from 2-18 eggs about 4 times a year, though on average will lay about 8. They will nest either on sandy beaches or near the riverside, but ideally prefer extremely dirty water. Like many other turtles, they rely upon temperatu ...

Podocnemididae
Podocnemididae is a family of pleurodire (side-necked) turtles, once widely distributed. Most of its 41 genera and 57 species are now extinct. Seven of its eight surviving species are native to South America: the genus '' Peltocephalus'', with two species, only one of which is extant (''P. dumerilianus'', the Big-headed Amazon River turtle); and the genus ''Podocnemis'', with six living species of South American side-necked river turtles and four extinct. There is also one genus native to Madagascar: '' Erymnochelys'', the Madagascan big-headed turtle, whose single species ''E. madagascariensis''. Like other pleurodire turtles, podocs have a "side-necked" defensive posture, turning the head sideways to hide it under the shell. Another characteristic of pleurodires is that the pelvis is fused to the shell which prevents pelvic motion, making it difficult to walk on land. Podocnemididae turtles live in aquatic environments and have shells streamlined to aid in swimming. The family ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelonoidis Denticulatus
The yellow-footed tortoise (''Chelonoidis denticulatus''), also known as the Brazilian giant tortoise, is a species of tortoise in the family Testudinidae and is closely related to the red-footed tortoise (''C. carbonarius''). It is found in the Amazon Basin of South America. The species name has often been misspelled as ''denticulata'', an error introduced in the 1980s when ''Chelonoidis'' was elevated to genus and mistakenly treated as feminine, an error recognized and fixed in 2017. With an average length of 40 cm (15.75 in) and the largest known specimen at 94 cm (37 in), this is the sixth-largest tortoise species on Earth, after the Galapagos tortoise, the Aldabra tortoise, the African spurred tortoise (''Geochelone sulcata'', typical size 76 cm (30 in)), the leopard tortoise (''Stigmochelys pardalis''), and the Asian forest tortoise (''Manouria emys emys'', typical size 60 cm (23.6 in)).

Chelonoidis Carbonarius
The red-footed tortoise (''Chelonoidis carbonarius'') is a species of tortoise from northern South America. These medium-sized tortoises generally average as adults, but can reach over . They have dark-colored (nearly black), “loaf”-shaped carapaces (top shell) with a lighter patch in the middle of each scute (shell segment), and a somewhat lighter-colored plastron (underbelly). They also have dark limbs dotted with brightly-colored scales, from which they get their name, that range from pale yellow to vivid or dark red. Visible differences are noted between red-footed tortoises from varying eco-regions. They are closely related to the more easterly-distributed yellow-footed tortoise (''C. denticulatus'') of the Amazon Basin. Their natural habitat ranges from savannah to forest edges around the Amazon Basin. They are omnivorous tortoises, consuming a wide assortment of plants, grasses, flowers, fruit and (notably) fungi, as well as the occasional earthworm or other invert ...

Testudinidae
Tortoises ( ) are reptiles of the family Testudinidae of the order Testudines (Latin for "tortoise"). Like other turtles, tortoises have a shell to protect from predation and other threats. The shell in tortoises is generally hard, and like other members of the suborder Cryptodira, they retract their necks and heads directly backward into the shell to protect them. Tortoises can vary in size with some species, such as the Galápagos giant tortoise, growing to more than in length, whereas others like the Speckled cape tortoise have shells that measure only long. Several lineages of tortoises have independently evolved very large body sizes in excess of , including the Galapagos giant tortoise and the Aldabra giant tortoise. They are usually diurnal animals with tendencies to be crepuscular depending on the ambient temperatures. They are generally reclusive animals. Tortoises are the longest-living land animals in the world, although the longest-living species of tortoise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
