Here's a breakdown of its mouth parts:
* Mandibles: These are the prominent, sharp, and powerful jaws that are the most noticeable part of the rhino beetle's mouth. They are used for chewing, fighting, and digging.
* Maxillae: These are a pair of smaller appendages located behind the mandibles, which help guide food into the mouth. They also have tiny bristles that aid in tasting.
* Labium: This is a lower lip that acts as a "floor" for the mouth, helping to hold food in place while the beetle chews.
The entire apparatus is designed for feeding on plant matter, such as decaying wood, leaves, and fruits. The mandibles are powerful enough to break through tough materials, and the maxillae and labium help to manipulate and process the food.
It's important to remember that rhino beetles don't use their mouths for biting in the traditional sense. Their mandibles are primarily used for feeding and fighting, and they don't pose a threat to humans.
