Here's a breakdown:
* Proboscis: This is the main part of the mouth, and it's formed by the elongated maxillae (jaw-like structures).
* Labrum: This is a small, upper lip that covers the proboscis when not in use.
* Mandibles: These are strong, toothed jaws used for biting and manipulating food, like pollen.
How it works:
1. The bumblebee extends its proboscis into the flower.
2. The proboscis uncoils, reaching the nectar at the base of the flower.
3. The bumblebee uses its tongue to lap up the nectar, drawing it into its mouth.
So, while bumblebees don't have teeth in the traditional sense, their proboscis and mandibles are specialized for their nectar-feeding lifestyle.
