Amphibians

Amphibians

The amphibians are called a group of animals that start their life in the water and then finish it on land. Metamorphosis is the process of the biological changing of any animal in its appearance from baby to adults. The word amphibian means both sides of life, and this is because the amphibian begins its life in the water and then goes on land and finishes his life.The most common amphibians frogs and salamanders.

The frog is an amphibian that goes through the metamorphosis from tadpole to adult frog. Some frogs have no patterns at all and are just a solid colour and others have very cool markings on them. Frogs make voice, and each type of frog has a different type of call. Only the male frogs make a call, the females do not. Male frogs will call out to the female frogs when they are ready to mate and the female frogs start finding them. The life cycle of a frog starts when the male and female mate either in the water or in a tree. The frog will lay a bunch of eggs for the male frog to fertilise. Male frog leaves and sometimes a female also. The rest surviving eggs  are generally expected to hatch somewhen between 7-9 days. They are called tadpoles, not frogs when they hatch. Tadpole has gills mouth and tail. With 9 weeks he grows some legs. 16 weeks is the time to complete the entire life cycle model for a frog and it becomes an adult after completing this cycle.

 

Salamanders

Salamanders belong to the order Caudata(tail, Latin). These animals are long and most of them resemble lizards by these familiar specifications: skins free of scales, toes without claws and the skin is covered with tubercles or they may be smooth. The largest in the family is the Chinese giant salamander. It can grow as long as 1.8m (5 ft, 11 in), and the most smaller in the family is Thorius Pennatula, from Mexico and very few from this family, are witnessed to grow more than 0.8 inches or 20mm in total. Their limbs (legs) are attached on the side of their bodies, with what they generally lay on the ground being flat. Salamanders live around ponds and other small bodies of fresh water. They are capable of anticipating whether there are any major environment pollution thanks to their characteristic of living only in pellucid water.

Caecilians

Caecilian, the critter, lengthy in physique and cylindrical in structure somehow resembles the snakes. The typical size of an adult Caecilian ranges from 8 to 75 cm (3 to 30 in). They can be delineated by ‘amphibians without any leg or foot’.

The skin of the Caecilian is composed of a great number of crossways folds. Their eyes have a peculiar characteristic, they are surrounded by and enclosed in the skin along with a couple of short tentacles which are near to the eyes. Most of the Caecilians dwell in burrows, underground in damp soil. There are many varieties of their eggs under the surface of the ground and when the larvae hatch, they move to the closest water.
