Amphibian The largest living amphibian is the 1.8 m (5 ft 11 in) Chinese giant salamander (Andrias davidianus), but this is dwarfed by the extinct 9 m (30 ft) Prionosuchus from the middle Permian of Brazil. The study of amphibians is called batrachology, while the study of both reptiles and amphibians is called herpetology.

Introduction to Amphibians The class Amphibia is composed of only 3 orders. Anura, which refers to tailless amphibians, includes frogs and toads (see Table: Similarities and Differences Between Frogs and Toads). This is the largest order with more than 3,500 species. Caudata refers to amphibians with tails—salamanders, newts, and sirens—and has about 375 species (see Table: Some Common Salamanders and Newts). The Gymnophiona order is made up of caecilians, legless, tailless amphibians that spend most of their time burrowing. It has about 160 species.

Goliath frog Goliath frog. The goliath frog or giant slippery frog (Conraua goliath) is the largest living frog on Earth. Specimens can grow up to 32 cm (12.6 in) in length from snout to vent, and weigh up to 3.25 kg (7.17 lb). This species has a relatively small habitat range in Cameroon and Equatorial Guinea.

Salamander Of course it depends on the particular salamander. From Wikipedia: They range in size from the minute salamanders, with a total length of 2.7 centimetres (1.1 in), including …the tail, to the Chinese giant salamander which reaches 1.8 metres (5.9 ft) and weighs up to 65 kg (140 lb).

Amphibians Some say that their name refers to the fact that amphibians live in two places- on land and in water. Others say their “double life” refers to their two distinct life stages – a larval and an adult stage. There are more than 6,000 species of amphibians living today.

Amphibian The number of known amphibian species is approximately 7,000, of which nearly 90% are frogs. The smallest amphibian (and vertebrate) in the world is a frog from New Guinea (Paedophryne amauensis) with a length of just 7.7 mm (0.30 in).

Salamander Sizes While most salamanders are moderately small in size, there are however certain varieties that differ in dimension. The Minute Salamander or Thorius, a genus in the Plethodontidae family, has a size range of 2 centimeters (0.8 inches) up to 2.7 centimeters (1.1 inches). Considered the largest salamander in the world, the Andrias davidianus or the Chinese Giant Salamander can reach a maximum length of 180 centimeters (6 feet) and a maximum weight of 65 kilograms (140 pounds), although it achieves this size only rarely.

Natural history Ambystoma is derived from either the Latin anabystoma, meaning “to cram into the mouth,” or from amblystoma, the Greek for “blunt mouth.”. DESCRIPTION: Large for a modern amphibian, the male California tiger salamander can reach up to 8.5 inches in length, the female up to seven. Adults have protruding eyes and long tails, and their slick bodies are mostly black with brilliant yellow spots and stripes on their back, sides, and tail.

What is the world's largest amphibian? The largest living amphibian is the Chinese Giant Salamander (Andrias davidianus). The maximum size of this river-dweller is 64 kg (140 lb) and 1.83 m (6 ft). Before aminotes became the dominant tetrapods, several giant amphibian-like tetrapods existed.

Tiger Salamander Some have no markings at all. Thick-bodied amphibians with short snouts, sturdy legs, and long tails, tigers are the largest land-dwelling salamander on Earth. They can grow to 14 inches (35 centimeters) in length, but the average size is more like 6 to 8 inches (15.2 to 20.3 centimeters). They are also the most wide-ranging salamander species in North America, living throughout most of the United States, southern Canada, and eastern Mexico.

- A frog species that appears to be the world's smallest has been discovered in Papua New Guinea by a US-based team. At 7mm (0.27 inches) long, Paedophryne amauensis may be the world's smallest vertebrate - the group that includes mammals, fish, birds and amphibians. The researchers also found a slightly larger relative, Paedophryne swiftorum.

- 1 The frilled lizard is sometimes called the bicycle lizard. This is because it runs on its hind legs when it is scared.  Most frilled lizards are less than 12 inches long. An open frill stretches from 9 to 14 inches wide, making it at least as big as the rest of the lizard.

- Amphibians include frogs, toads, newts, salamanders and the curiously worm-like caecilians. Although most transform from aquatic larvae to terrestrial adults, some amphibians, such as the golden alpine salamander, live permanently on land, while others, such as the axolotl, never leave the water. Sadly, around 41 percent of amphibians are at risk of extinction. Blue-eyed bush frog.

They are superficially similar to reptiles but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed.

Critter Catalog Spotted salamander larvae are 12-13 mm long when they hatch, with feathery gills and only their front legs present. Larvae grow quickly and transform within 2 to 4 months after hatching. Average size after metamorphosis ranges between 27 and 60 mm, depending on the conditions in the pond.

- Main Characteristics. Hippopotamuses are large, semi-aquatic mammals. They have a body length between 2.7 and 3.5 m (9 - 11.5 ft), a tail length of approximately 56 cms (22 inches) and they weigh between 1.4 and 3.2 tonnes (1.4 - 3.2 tons). They are large, heavy bodied animals that have short, stumpy legs with webbed toes.

Difference between Reptiles and Amphibians Amphibians are animals that live part of their lives in water and part on land. They are vertebrates and are also ectothermic; they cannot regulate their own body heat, so they depend on sunlight to become warm and active.

- California Tiger Salamanders are considerably large for todays amphibians. The male can reach 8.5 inches long and the females 7 inches (NPWRC 2002, FWS 2003). Males differ from females in their overall size as well as their enlarged cloacae during breeding season (FWS 2003).

Indeed, members of the genus, which may grow up to three feet long, are often better known by the name Congo eel or Congo snake.mphiuma is a genus of aquatic salamanders that have very small limbs and are sometimes misidentified as snakes or eels.

lever The muscles of the body produce the forces that move the levers. The basic components of a lever are the fulcrum, the force arm, and the weight arm. A first-class lever, such as the joint between the base of the skull and the first cervical vertebra, has a fulcrum between the weight and the applied force. The body contains few second-class levers, which have the weight between the fulcrum and the force.

Chinese Giant Salamander - World's Largest Amphibian Chinese Giant Salamander - World's Largest Amphibian. The Chinese giant salamander is the biggest amphibian in the world growing up to 6 ft (180 cm) long. That is one big salamander. The long fat tail can be 60 percent of its length. It is mainly found in the waters in and around China, hence the name but there is a very similar species in Japan as well.

Earth's Endangered Creatures The Chinese giant salamander (Andrias davidianus) is the largest salamander and largest amphibian in the world, reaching a length of 180 cm (6 ft), although it rarely—if ever—reaches that size today.It is endemic to rocky, mountain streams and lakes in China.ccording to a recent study, 90% of the Chinese giant salamanders’ habitat was destroyed by the year 2000, and there are many human-related causes of such massive destruction. Because the salamander dwells in free-flowing streams, industrialization is a large problem for many stream-dwelling species.

THE EXTINCTION CRISIS No group of animals has a higher rate of endangerment than amphibians. Scientists estimate that a third or more of all the roughly 6,300 known species of amphibians are at risk of extinction [ 6 ]. The current amphibian extinction rate may range from 25,039 to 45,474 times the background extinction rate [ 7 ].
