Study Notes
Tympanic Membrane
- Located behind a frog's eye, the tympanic membrane acts as its eardrum.
- It transmits sound waves to the middle and inner ear, enabling hearing both in air and underwater.
Nictitating Membrane
- Frogs possess a third eyelid known as the nictitating membrane.
- This membrane serves multiple purposes: lubricating the eyes and providing protection, aiding survival in both terrestrial and aquatic environments.
Vocal Sacs
- Male frogs have vocal sacs that amplify their mating calls.
- These sacs play a crucial role in advertisement calls for attracting females during mating season.
Vomerine and Maxillary Teeth
- Vomerine teeth are essential for gripping prey, working in tandem with the tongue.
- These teeth focus on aiding in the capture and consumption of food.
Vestigial Thumb
- Male frogs have more muscular thumbs than females, reflecting differences in anatomy related to mating.
- The hindlegs feature webbed toes for swimming, alongside a rudimentary sixth digit which is vestigial.
Tongue Attachment
- The unique attachment of the frog's tongue allows for rapid extension and retraction, crucial for capturing prey.
