Which type of snake is known for leaving a semicircular pattern of small teeth marks?

The correct answer is that the coral snake is known for leaving a semicircular pattern of small teeth marks due to its unique dental structure and biting mechanism. Coral snakes are elapids, which means they have fixed fangs that are designed to deliver venom deep into their prey. These fangs, being relatively short and positioned towards the front of the mouth, create a distinct bite pattern when they latch onto their victim.

The semicircular marks are a result of the arrangement of these fangs, which can puncture the skin in a curved line. This is characteristic of coral snakes as they tend to grasp their prey rather than deliver a single poke, allowing the bite pattern to reflect their anatomical features. In contrast, other snake species, such as the rattlesnake or water moccasin, have different fang structures or biting techniques that produce different bite patterns. The garter snake, being non-venomous and having smaller teeth, would not leave prominent tooth marks at all. This information highlights the unique characteristics of the coral snake and helps identify it based on the bite pattern it leaves behind.
