Tiger salamander larvae Tiger salamander pics

salamanders grow to a typical length of 6–8 inches (15–20 cm). They can reach up to 14 inches (36 cm) in length, particularly neotenic individuals. Adults are usually blotchy with grey, green, or black, and have large, lidded eyes. They have short snouts, thick necks, sturdy legs, and long tails. Their diet consists largely of small insects and worms.

Tiger salamanders are almost entirely terrestrial as adults, and usually only return to the water to breed. But also they partly live in both land and water. They also like to swim,even if they are terrestrial. They also are good swimmers. Like all ambystomatids, they are extremely loyal to their birthplace, and will travel long distances to reach it. However, a single tiger salamander has only a 50% chance of breeding more than once in its lifetime. Males nudge a willing female to initiate mating, and then deposit a spermatophore on the lake bottom.
These are known as small morph adults. Other larvae, especially in ancestral pools and warmer climates, may not metamorphose until fully adult size. These large larvae are usually known as waterdogs, and are used extensively in the fishing bait and pet trade. Some populations may not metamorphose at all, and become sexually mature while in their larval form.
Since they tend to breed in semipermanent wetlands, larval Tiger Salamanders often experience mass mortality in association with pond drying. Introduced fishes have also been known to reduce, and levels they also experience reduced growth and longer larval periods. The effect of agricultural pesticides in endocrine disruption has also been researched. All of these issues have collectively influenced Tiger Salamander populations.

white rhinoceros some life highlightswhite rhinoceros is not actually white, but light grey. The name was derived from the Afrikaans word wyt, so perhaps it would more properly be called "square-lipped rhinoceros: because wyt refers to the wide, square muzzle that is so well suited to grazing on grass, the abundant food in its grassland habitat. The white rhinoceros once occurred extensively south of the Sahara. The northern subspecies is close to extinction. The southern subspecies came close to extinction in the late-1800s but it responded to conservation measures and populations have increased greatly. The two horns are positioned one behind the other and its thick hide is relatively smooth. Horns are made of compressed hair. Like most rhinoceroses, the young are quite hairy but adults are hairless except for their ear rims, tail tip and eyelashes. White Rhinoceros or Square-lipped rhinoceros (Ceratotherium simum) is one of the five species of rhinoceros that still exist and is one of the few megafaunal species left. It has a wide mouth used for grazing and is the most social of all rhino species. This suggests the origin of the word was before codification by Dutch writers. A review of Dutch and Afrikaans literature about the rhinoceros has failed to produce any evidence that the word wijd was ever used to describe the rhino outside of oral use. Other popular theories suggest the name comes from its wide appearance throughout Africa, its color due to wallowing in calcerous soil or bird droppings or because of the lighter colour of its horn. An alternative common name for the White Rhinoceros, more accurate but rarely used, is the square-lipped rhinoceros. the last offspring came to the world in 2000, the zoo management decided to stimulate the Rhino's sexual appetite by putting them back into their natural habitat. The agreement with Kenya government expects the Rhinos never to be returned to the Czech Republic. Reportedly they are supposed to be heavily guarded to ensure, that they won't be killed by poachers. The Northern White Rhino (Ceratotherium simum) formerly ranged over parts of north-western Uganda, southern Chad, south-western Sudan, the eastern part of Central African Republic, and north-eastern Democratic Republic of the Congo. Poachers reduced their population from 500 to 15 in the 1970s and 1980s. From the early 1990s through mid 2003, the population recovered to more than 32 animals. Surveys in 2000 indicated that the population had started recovering, with 30 animals confirmed in 2000, and possibly six others Since mid 2003, poaching had intensified and reduced the wild population to only 5 to 10 animals (7 actual count worldwide).

Yellow Anacondas are smaller than their close relation, the Green Anaconda. They reach lengths of approximately 3 m (9.8 ft) and they are known to have a life span of approximately 25 - 30 years.
Their base colour is a yellowish/brown and they are covered in black blotches and rosettes.Yellow Anacondas mainly feed on birds, rodents and fish. They prefer to hunt live prey, but will scavenge for dead animals. They suffocate their prey by wrapping themselves around it and constricting.Yellow Anacondas breed during the rainy season and usually in the water. They will have litters of 20 - 40 but as many as 100 young are possible. Gestation usually lasts approximately 6 months and they become sexually mature at 3 - 4 years of age.
