1. Eyes:
* Structure: Large, protruding eyes positioned on top of the head for wide-angle vision, especially important for spotting prey and predators.
* Function: Frogs have excellent color vision, helping them detect moving objects and navigate their surroundings. Their eyes are adapted for both underwater and aerial vision.
2. Ears:
* Structure: Lack external ears; instead, have a tympanum (eardrum) located behind the eye.
* Function: The tympanum vibrates in response to sound waves, transmitting vibrations to the inner ear for processing. Frogs are sensitive to low-frequency sounds, particularly important for communication and detecting predators.
3. Nose:
* Structure: Located at the tip of the snout, with two external nostrils.
* Function: Detects odors in the air, aiding in finding food and avoiding predators. They can also use their nostrils to breathe when submerged in water.
4. Tongue:
* Structure: Long, sticky tongue attached to the front of the mouth.
* Function: Extends rapidly to capture prey. The tongue is covered in a sticky mucus that helps to trap insects.
5. Skin:
* Structure: Thin and moist, with numerous sensory receptors.
* Function: Acts as a secondary sense organ, detecting touch, pressure, temperature, and even pain. Also helps with respiration and water absorption.
6. Lateral Line System:
* Structure: A series of sensory organs located along the sides of the body.
* Function: Detects vibrations and water pressure changes, aiding in navigation and detecting prey or predators underwater.
7. Vomero-Nasal Organ:
* Structure: Located in the roof of the mouth.
* Function: Detects pheromones, aiding in communication, especially during mating season.
These specialized sensory organs allow frogs to thrive in their diverse habitats, enabling them to hunt, avoid predators, communicate, and navigate their surroundings effectively.
