Black snakes are a group of snakes that are either entirely black or mostly black in color. There are several species of black snakes, and some of them are difficult to identify for those inexperienced with snakes.
Scientifically and taxonomically speaking, black snakes are those which belong to the Pseudechis genus, and there are nine such snake species in this genus. However, there are other snakes with the descriptor “black” in their name, which also belong to different categories.

9 Types Of Black Snakes
Black Rat Snake
The black rat snake, also known as the eastern rat snake, is a non-venomous constrictor that is native to the central and eastern United States. Here are some interesting facts about black rat snakes:
– Appearance: Black rat snakes are large snakes that can grow up to 7 feet long. They have shiny black scales on their back and a light-colored belly, and their throat and chin are white. The head of an eastern rat snake is wider than the neck and the rest of the body.
– Habitat: Black rat snakes live in fields, woodlands, farmlands, and around suburban communities from Connecticut to South Carolina and west to the middle of Kansas and Oklahoma.
– Diet: Adult black rat snakes primarily eat mice, rats, squirrels, and birds, as well as bird eggs. They are a common predator on wood duck eggs.
– Behavior: Black rat snakes are excellent climbers and spend much of their time in trees. They also tend to seek shelter in rock outcroppings and stone walls, and may be found in the vicinity of barns, abandoned buildings, and trash piles, presumably hunting for rodents. When approached, black rats usually remain motionless. With their cryptic black coloration, they become invisible against the bark or dark forest floor.
– Conservation: The black rat snake is considered stable throughout its range.
– Identification: Most confusion in black rat snake identification is due to the juvenile pattern. Baby or juvenile snakes have a gray and black pattern of scales.
Black rat snakes are an important part of the ecosystem, as they help control rodent populations.
Black Kingsnake
The black kingsnake is a non-venomous constrictor that belongs to the Lampropeltis genus. Here are some interesting facts about black kingsnakes:
Appearance:

– The belly of black kingsnakes has a black and white checkered pattern.
– Their head is not distinct from their neck, and their scales are smooth and shiny.
– Adult black kingsnakes may reach up to 4 feet in total length, although most individuals are smaller.
Habitat:
– Black kingsnakes are found in a variety of habitats, including forests, fields, shrubby areas, forest edges, and urban areas.

Behavior:
– Black kingsnakes breed in the spring, and females deposit eggs in moist areas during the early summer.
– Hatchlings are often found in late summer or early fall.
– Black kingsnakes are active during the day and at night, and they tend to hunt during the daytime, as they rely on their (albeit limited) vision for predation.
