Fish can sense sound through their lateral lines and their otoliths (ears). Some fishes, such as some species of carp and herring, hear through their swim bladders. [9] Hearing is well-developed in carp, which have the Weberian organ, three specialized vertebral processes that transfer vibrations in the swim bladder to the inner ear.
Underwater hearing is by bone conduction, and localization of sound appears to depend on differences in amplitude detected by bone conduction. [57] Aquatic animals such as fish, however, have a more specialized hearing apparatus that is effective underwater. [58] Fish can sense sound through their lateral lines and their otoliths (ears).
One physiological characteristic of sleep goes by the name of "homeostatic regulation". This is the notion that animals need a more or less constant amount of sleep every day, so that if a subject is deprived of sleep one day, the amount of sleep tends to "rebound" (increase) the next few days. This has been observed in zebrafish. At night ...
[1] [2] This suprabranchial organ, or labyrinth organ, allows some species the capability of traveling short distances on land (walking catfish). [1] Air-breathing organ of walking catfish. The dorsal fin base is very long and is not preceded by a fin spine. The dorsal fin may or may not be continuous with the caudal fin, which is rounded.
The Weberian apparatus functions by transmitting auditory signals straight from the gas bladder, through the Weberian ossicles and then straight into the labyrinth structures of the inner ear. The structure essentially acts as an amplifier of sound waves that would otherwise be only slightly perceivable by the inner ear structure alone.
The big three in sleep sounds are white noise, brown noise, and pink noise, but there are many other noise types, including purple noise, gray noise, and even black noise (a.k.a. good ol ...
Oblique view of a goldfish (Carassius auratus), showing pored scales of the lateral line system. The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water.
What happens to catfish on ice at Nashville Predators games? Members of the ice crew gather the carcasses, put them in a gold bucket and deliver them immediately into a trash compactor at the arena.
