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.
Underwater hearing is by bone conduction, and localization of sound appears to depend on differences in amplitude detected by bone conduction. [7] As such, aquatic animals such as fish have a more specialized hearing apparatus that is effective underwater. [8] Fish can sense sound through their lateral lines and their otoliths (ears).
Goldfish that have constant visual contact with humans also stop considering them to be a threat. After being kept in a tank for several weeks, sometimes months, it becomes possible to feed a goldfish by hand without it shying away. Goldfish have a memory-span of at least three months and can distinguish between different shapes, colors, and ...
One of the great things about being a goldfish, in theory, is that if we dwell on our mistakes less, we can take more risks. We often shy away from trying something new because we are worried it ...
Fish intelligence is "the resultant of the process of acquiring, storing in memory, retrieving, combining, comparing, and using in new contexts information and conceptual skills" [1] as it applies to fish.
Whispering-gallery waves, or whispering-gallery modes, are a type of wave that can travel around a concave surface.Originally discovered for sound waves in the whispering gallery of St Paul's Cathedral, they can exist for light and for other waves, with important applications in nondestructive testing, lasing, cooling and sensing, as well as in astronomy.
Many popular aquarium fish such as goldfish and loaches have these structures. Members of the genus Botia such as clown loaches are known to make distinctive clicking sounds when they grind their pharyngeal teeth. Grunts (family Haemulidae) are so called because of the sound they make when they grind them. [2]
File:Goldfish Memory.gif Taking a stand against the misconception about goldfish memory. I would like to add this gif to the Intelligence section of this article. The gif is my own work. I believe adding it to the article will increase visual interest and will bring the readers attention to the common misconception about goldfish memory.
