Classification of spotted salamander

Kingdom: Animal

Phylum: Vertebrate Chordates

Class: Amphibians

Scientific name: Ambystoma maculatum

 

Characteristics and shape of the spotted salamander

The spotted salamander has a length of 15 to 25 cm. The tail of this animal constitutes 30% of the total length, while it weighs 30 grams on average. The weight and size of this animal varies according to the region in which it lives.

 

Spotted salamander appearance

The spotted salamander is a medium-sized terrestrial salamander with a long stocky body, a rather large conical tail, small slender legs with 4 toes and a flat, round head. His black eyes are prominent and his jaw is wide. It also contains glands throughout the body that secrete toxic mucus. It has small lungs, which replace the gills, which fall off during metamorphosis. And her skin is shiny, sticky and smooth. It is black to dark gray, almost gray and pink on the flank and belly. Its upper body is mottled with well-defined yellow dots.

 

How do spotted salamanders breathe?

The spotted salamander breathes through the lungs and skin in adulthood, and breathes through the gills when in the form of larvae. 

Characteristics and characteristics of the spotted salamander

Like other salamanders, the spotted salamander secretes a toxic fluid through certain glands. It also has the ability to regenerate the damaged parts of his body. It can regrow a limb, a tail, or even a vital organ, even a part of the brain.

 

Ecology and distribution of spotted salamanders

The spotted salamander lives primarily in parts of eastern North America.

 

Habitat and ecology of the spotted salamander

The spotted salamander lives mainly in temperate mixed or deciduous forests, near water points. For breeding and when in their larval form, they are seen in ponds and ponds as well as in swamps.

 

Food pattern of spotted salamanders

The spotted salamander is a carnivorous animal, it is an insect eater.

 

Spotted salamander food and prey

Adult spotted salamanders feed mainly on invertebrates and insects such as crickets, as well as worms and spiders. While spotted salamander larvae feed initially on zooplankton, then feed on small isopods and amphipods.

 

The social life of the spotted salamander

The spotted salamander is a solitary animal that spends the year alone. Except for the breeding time where you find males fighting for females. The spotted salamander is a nocturnal and crepuscular animal that spends the day in its sanctuary, in a burrow or under a tree trunk or rock. It is active at night and is active for hunting. It does not hunt far from its shelter and hunts the spotted salamander in the dark, using its excellent sense of smell and hearing, as it locates its prey, and then catches it. Each winter, these amphibians hibernate in their lair. In early spring, it emerges from hibernation and migrates to spawning points in the water, usually where it was born. The spotted salamander is a silent animal and will simply make some small noises if threatened.

 

Predators of the spotted salamander

In adulthood, the spotted salamander is preyed upon by striped skunks, raccoons, turtles, and snakes. While the larvae are preyed upon by crayfish, wood frogs, some insects and aquatic larvae.

 

spotted salamander lifespan

The average life expectancy of spotted salamanders in the wild is about 20 to 25 years. And in captivity up to 30 years, but on average about 25 years.

 

spotted salamander reproduction

The spotted salamander is a spawning animal. It is polygamous and reaches sexual maturity at about two years of age. The breeding season is in the spring, usually from April to May. Male spotted salamanders compete against each other to fertilize eggs and fertilization in spotted salamanders is external as the male directs the female to a sperm carrier, which the male releases into the pond water. The female deposits her eggs in groups that attach to aquatic plants. The number of eggs is from 100 to 370 eggs, 200 on average, are emerald green or bluish-white. The incubation period is approximately one to two months. At birth, the spotted salamander larva is light brown in color with dark spots and external gills. The spotted salamander larva metamorphoses and loses its gills between 2-4 months. However, some larvae may go into hibernation and morph the following spring.

 

Spotted salamander threats

The spotted salamander is less worrisome ( LC) according to the IUCNLoss and fragmentation of its habitat through deforestation, deforestation, pollution of water points, agriculture, and road collisions are among the major threats to the spotted salamander . The number of spotted salamanders in the wild is currently unknown, as it is a common and widespread species. However, it will be between 100,000 and 1,000,000 salamanders.
