Question

Что помогает крокодилу держаться под водой в течении 2часов

Answer 1

Крокодилы всплывают наружу, чтобы вдохнуть хорошенько, а когда он ныряет под воду, его ноздри и слуховые отверстия закрываются клапанами

Answer 2

How Crocodiles Stay Submerged for 2 Hours in Water Currents

Crocodiles are able to stay submerged in water for extended periods of time due to several key adaptations:

1. Efficient Oxygen Usage: - Crocodiles have a low metabolic rate and can hold their breath for long periods, allowing them to efficiently use the oxygen stored in their lungs and muscles. - This enables them to stay submerged for extended periods without needing to surface for air.

2. Specialized Muscles and Lungs: - Crocodiles have specialized muscles and lungs that allow them to control their buoyancy and remain submerged. - Their lungs are designed to extract a high percentage of oxygen from each breath, and their muscles are adapted for efficient oxygen utilization.

3. Slowing Heart Rate: - When submerged, a crocodile's heart rate slows down, reducing the need for oxygen and allowing them to conserve energy while underwater. - This adaptation helps them to stay submerged for extended periods, even in water currents.

4. Anaerobic Respiration: - In addition to efficient oxygen usage, crocodiles can also rely on anaerobic respiration for energy when submerged for long periods. - This process allows them to continue functioning without oxygen for a limited time, further aiding their ability to stay submerged in water currents.

These adaptations collectively enable crocodiles to stay submerged in water for extended periods, even in strong currents, as they efficiently utilize oxygen, control their buoyancy, conserve energy, and have mechanisms for alternative energy production.
