Question

Do crabs have ear to hear sound?         

Answer 1

Most crabs do not have ears in the traditional sense. Instead, they have specialized hair-like structures called setae that are sensitive to vibrations and changes in water pressure. These setae are located on the crab's antennae and other parts of their body. This allows the crab to sense and respond to sounds, movements, and changes in their environment, even if they cannot hear in the same way that humans do.

Answer 2

Crabs do not have ears to hear sound. Instead, they use mechanoreceptors to detect acoustic signals Aquatic vertebrates have ear holes containing mechanoreceptors, while aquatic invertebrates such as lobster, crabs, and shrimps have external sensory hairs and internal statocysts Fiddler crabs, which are found along sea beaches and brackish intertidal mud flats, have been shown to exhibit a constant circadian rhythm that mimics the ebb and flow of the tides, turning dark during the day and light at night Golden ghost crabs and Ocypode ghost crabs are predominantly nocturnal and are generalist scavengers and predators of small animals Shore crabs are also nocturnal predators.

Answer 3

No, crabs do not have ears in the way that humans do. Instead, they have tiny sensory hairs on their legs and body that allow them to detect vibrations and changes in water pressure. This helps them to navigate their environment and avoid danger, such as predators or underwater disturbances.

Answer 4

Crabs do not have ears in the traditional sense. Instead, they have small structures called statocysts that allow them to perceive vibrations and changes in water pressure, providing a sense of hearing and balance.

Answer 5

All crabs and crustaceans in general lacks ears instead they have tiny microscopic hairs on their shells which they use to detect changes in water pressure and signal their nervous system for action 

Answer 6

Crabs primarily detect sound through small structures called statocysts, located in their front body near the base of the antennae. These statocysts contain tiny particles that respond to changes in pressure caused by sound waves. While crabs don't have ears in the way humans do, their ability to sense vibrations and pressure changes allows them to perceive sounds and navigate their environment.
