Pareidae

The Pareidae are a family of snakes, commonly known as keeled slug-eating snakes or snail-eating snakes, found in Southeast Asia, southern China, and western India. These snakes are specialized predators, feeding primarily on snails and slugs.

Characteristics:

Pareid snakes possess several adaptations related to their molluscivorous diet. These adaptations include:

• Asymmetrical Jaw: Many species have asymmetrical jaws, with one side being more muscular and equipped with more teeth than the other. This asymmetry aids in extracting snails from their shells.
• Elongated Mandibles: Their mandibles are elongated, allowing them to reach deep into snail shells.
• Reduced Dentition: While they possess teeth, the number is relatively reduced compared to other snakes.
• Keeled Scales: Most members of the family have keeled scales, giving them a rough texture.

Taxonomy:

The family Pareidae was formerly included within the Colubridae family, but is now recognized as a distinct family based on morphological and molecular data. The classification within the family has undergone revisions, and currently includes the following genera:

• Aplopeltura
• Asthenodipsas
• Dipsas
• Geotrypetes
• Pareas

Habitat and Distribution:

Pareid snakes are generally found in humid environments, such as rainforests and moist forests. Their distribution is limited to Southeast Asia, parts of southern China, and western India.

Conservation Status:

The conservation status of various Pareid species varies depending on the specific species and the threats they face. Habitat loss due to deforestation and agricultural expansion are major concerns for many species within this family. Further research is needed to assess the conservation status of many species accurately.
