Average Size and Life Span
Salamanders vary in dimensions. Some might only get to the size of 3.9 cm while others may reach up to the magnitude of 180 cm. Among the smallest salamanders is the 4-toed salamander (Hemidactylium scutatum) that just reaches 5-9 cm. On the other hand, among the largest is the mudpuppy (Necturus maculosus) that may reach a length of 43 cm. Salamander’s life span also changes. The Chinese giant salamander can live for about 52 years while other salamanders may only reach a year or two.
Salamanders closely resemble the lizards. That is the main reason they’re typically mistaken as lizards. However, salamanders do not have the characteristics that lizards have.

Their heart includes 2 atria and one ventricle, making it a 3-chambered organ.
Salamanders hibernate every year so as to survive. Since they cannot endure extremely cold temperatures, they will need to dig underground. Aquatic salamanders are generally active at any given time of the year while terrestrial salamanders are only active during night time, or when the land is moist or damp. Temperate seasons or warm period may immediately cause them dehydration.

Internally, the male will fall jellylike capsule of sperms and the female will eventually take these sperms through the lips of the cloaca. The eggs are fertilized as they’re pushed out.
Normally, salamanders are carnivorous. Bigger salamanders are fond of eating earthworms and larvae of insects. Smaller species like small insects and small invertebrates while salamander larvae eat tadpoles.
Importance in the Environment
Salamanders are thought of as great advantage in the area of agriculture and forest industry since they consume harmful insects which may destroy crops and plants. Without them, a break in the food chain can happen and problems associated with plant industry may come up.
Salamanders today are continuously decreasing in quantity because a great deal of universities and research labs catch them and make them subjects in their studies. That is why local laws are protecting these salamanders so as to keep their numbers in the wild. Take your part in the campaign of saving salamanders.
