Correct option is A
The correct answer is: (a) It is found in catfish and facilitates sound transmission from the swim bladder to the inner ear.
Explanation:
Weberian ossicles are a set of small bones found in certain fish species, particularly catfish, that help transmit sound vibrations from the swim bladder to the inner ear. This adaptation aids in the detection of sound waves, helping the fish to hear underwater. The swim bladder, which is involved in buoyancy, plays a crucial role in this process by vibrating in response to sound, and the Weberian ossicles transmit these vibrations to the inner ear for processing.
Information Booster:
Weberian ossicles are present in certain species of fish, such as catfish.
They play a critical role in sound transmission, linking the swim bladder to the inner ear.
This adaptation allows fish to detect vibrations and sounds in water, which is crucial for communication and navigation.
The swim bladder serves as a sound detection organ in these fish, vibrating in response to sound.
The ossicles convert these vibrations into mechanical signals, which are then transmitted to the inner ear.
This system is especially effective for fish that live in environments where sound waves travel faster and over long distances in water.
Additional Information:
Option 2: "It is found in sea stars and helps them in detecting surface vibrations" is incorrect because Weberian ossicles are specific to fish, not sea stars.
Option 3: "It is found in anurans and contributes to transmitting sound waves from the eardrum" refers to amphibians like frogs, which do not possess Weberian ossicles but rather a different sound reception mechanism.
Option 4: "It is found in snakes and contributes to receiving vibrations from the surroundings" is incorrect because snakes do not have Weberian ossicles; they rely on other methods of vibration detection, such as their jawbones.
