Monkey lips, in the context of sperm whales, are not related to primate anatomy. Instead, they refer to a specialized anatomical structure found in the sperm whale. Specifically, monkey lips are a thick flap valve that serves an important function in the whale's respiratory system.
Detailed Explanation of Monkey Lips
Here's a breakdown of what monkey lips are:
- Structure: Monkey lips are composed of extremely dense collagen. This collagen creates a robust, fleshy flap.
- Location: These lips frame the slit-like aperture of the sperm whale's blowhole.
- Function: The primary function of monkey lips is to act as an air-tight valve. They effectively seal the blowhole.
- Observation: In deceased sperm whales, these lips are noted to be closed tightly, indicating their role in maintaining an airtight seal. This observation, according to Norris & Harvey (1972), highlights the lips' importance as a valve.
Key Characteristics Summarized
| Feature | Description |
|---|---|
| Composition | Extremely dense collagen |
| Shape/Structure | Thick flap valve framing the blowhole |
| Function | Air-tight seal for the blowhole |
| State in Dead Whales | Closed tightly |
| Reference | Norris & Harvey, 1972 |
In essence, monkey lips are crucial to the respiratory mechanics of sperm whales, facilitating controlled breathing by creating an airtight seal when submerged. The name "monkey lips" appears to be somewhat arbitrary, perhaps referring to the appearance of this structure, rather than a biological connection to monkeys. The name "monkey lips" is specific to the sperm whale anatomy.
