Genus Calliophis is a group of venomous snakes, commonly known as coral snakes. These snakes are identified by their brightly colored bands of red, yellow, and black. There are several synonyms for the genus Calliophis, including Micruroides, Leptomicrurus, and Othriophis. These synonyms are used interchangeably by different taxonomists and researchers. However, there is still some debate about the exact classification of these snakes and whether they belong to the same genus or not. Regardless of their classification, these snakes are known for their potent venom and the danger they pose to humans. It is important to exercise caution and seek medical attention immediately if bitten by a coral snake.
