Think You Know Snakes?

The natural world is full of fascinating plants and animals covered in dazzling colors and astonishing designs, especially when it comes to snakes. Many desert snakes have neutral, sandy colors, while others have bright and bold patterns that could easily inspire new fashion trends. While some snakes have large blotches, others sport stripes and spots of all shapes and sizes. There are even snakes with polka dots. Let’s take a closer look at 18 snakes with dots.

18.      Twin Spotted Rattlesnake

The Twin-Spotted Rattlesnake is a small snake with a grey, blue-grey, grey-brown, or reddish-brown body. Two rows of small dark spots run down the snake’s back, and more small dark dots cover its body. These snakes can grow up to 26 inches in length and have very large, triangular-shaped heads. Twin spotted rattlesnakes live in the Sonoran Desert in Arizona and Mexico, often in high altitude mountain ranges, rocky outcrops, forests, and canyons. These snakes mostly eat lizards, birds, and small rodents, but occasionally they will also hunt other snakes as well.

The Yellow Spotted Wolf Snake is a small snake, usually around 13 inches in length with a small head and rounded snout. This snake has a black, glossy body with small yellow dots across its back. In some snakes these yellow dots form clusters and small crossbands. The yellow spotted wolf snake is nonvenomous and lives in the Western Ghats of India. Unfortunately, however, this snake is often unnecessarily killed because it is mistaken for a venomous krait.

16.      Spotted House Snake or Spotted Rock Snake

The Spotted House Snake is not easily confused with other snakes in South Africa because of its unique patterns and colors.

The Spotted House Snake, or Spotted Rock Snake, lives in many of the rocky regions of South Africa. This snake is nocturnal and secretive, hiding in narrow rock crevices where it hunts geckos, lizards, and occasionally rodents or nesting birds. There are many different colors of spotted house snakes. Commonly these snakes have brownish, tan, cream, or pinkish bodies with dark brown or reddish-brown spots spaced out along their backs. Spotted house snakes are small and slender and grow between 16-24 inches on average. Their heads are wide and very flat, possibly so they can more easily navigate through narrow crevices in the rocks.

15.      Speckled Kingsnake

The Speckled Kingsnake has a shiny black or dark brown body, with a mass of tiny yellow dots that give it its namesake “speckled” appearance. These colored dots provide a stark contrast to the snake’s dark body, which is why it is also called the “Salt and Pepper Snake”. Speckled kingsnakes are nonvenomous and grow up to 48 inches in length. These snakes are endemic to southern and central regions of the United States. They typically prefer to live in moist or wet habitats but often travel into dry areas as well. These snakes are common in swamps and near rivers, where they hunt lizards, small rodents, and other snakes. Speckled kingsnakes are unique because they can eat venomous snakes like cottonmouths, copperheads, and rattlesnakes.

14.      Night Snake

The Night Snake is a small snake, measuring between 12-26 inches long with a light brown, beige, or light grey body. There are brown or darker grey blotches running along the snake’s back, with smaller dark dots marking both sides of its body. Night snakes are slightly venomous, but they are not dangerous to humans. These snakes are secretive, and like their name, are only active at night. Night snakes live in North America, from Mexico through the western United States and up through Canada’s British Columbia. These snakes are docile but are often mistaken for young rattlesnakes. They mostly eat lizards, salamanders, blind snakes, frogs, juvenile rattlesnakes, and large insects.

13.      Spotted Brown Snake

The Spotted Brown Snake has a yellow, tan, or orange-colored body with tiny dark dots on its back. These dots are accentuated and appear bolder when the snake moves. Some snakes also have additional dark bands around their bodies. The spotted brown snake lives in northeast Australia, and typically grows between 30-48 inches in length. This snake often buries itself deep inside cracks and crevices in the earth, usually near a water source. The spotted brown snake is venomous and eats reptiles and frogs. Occasionally it will also eat small mammals or birds. This snake has a highly toxic venom. In fact, its venom is more toxic than the dugite snake and the Indian Cobra.

The Spotted Bush Snake has a bright green body plastered with numerous tiny black dots. Sometimes these dots cluster together to form diagonal lines or small zigzagging bands, in addition to many singular dots sprinkled along the snake’s body. Spotted bush snakes are most common in trees and use their keeled scales for climbing vertical surfaces as they hunt tree frogs and lizards. At times people mistake these snakes for the dangerous green mamba and tragically kill them. However, spotted bush snakes are nonvenomous and completely harmless.
