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. The sensory ability is achieved via modified epithelial cells , known as hair cells , which respond to displacement caused by motion and transduce these ...
The lateral line in fish and aquatic forms of amphibians is a detection system of water currents, consisting mostly of vortices. The lateral line is also sensitive to low-frequency vibrations. It is used primarily for navigation, hunting, and schooling. The mechanoreceptors are hair cells, the same mechanoreceptors for vestibular sense and hearing.
The lateral line is clearly visible as a line of receptors running along the side of this Atlantic cod. The lateral line is a sense organ used to detect movement and vibration in the surrounding water. For example, fish can use their lateral line system to follow the vortices produced by fleeing prey. In most species, it consists of a line of ...
The fish lateral line consists of thousands of hair cells. [3] In fish, a neuromast is a fine hair-like structure that uses transduction of rate coding to transmit the directionality of the signal. [4] Each neuromast has a direction of maximum sensitivity providing directionality. [5]
HLLE begins as small pits of receding epithelium (skin) around the fish's head and/or lateral line, and sometimes onto the unpaired fins. Rarely fatal, it does cause disfigurement, making the fish less suitable for public aquarium display. At least 20 families of fish have been identified as having developed HLLE in captivity.
A rare fish species thought to be extinct for over 80 years was rediscovered in India. ... and the highest number of lateral-line scales among all snakeheads of the Gachua group,” Thackeray ...
This sense is common in aquatic animals, the most cited example being the lateral line system, the array of hydrodynamic receptors found in fish and aquatic amphibians. [4] Arthropods (including crayfish and lobsters) and some mammals (including pinnipeds and manatees) can use sensory hairs to detect water movements. Systems that detect ...
The roach is a small fish, often reaching no more than about 35 centimetres (14 in); maximum length is 50 cm (20 in). Its body has a bluish-silvery colour and becomes white at the belly. The fins are red. The number of scales along the lateral line is 39–48. [3] The dorsal and anal fins have 12–14 rays.
