Fish intelligence is "the resultant of the process of acquiring, storing in memory, retrieving, combining, comparing, and using in new contexts information and ...
Fish vision shows adaptation to their visual environment, for example deep sea fishes have eyes suited to the dark environment. Fish and other aquatic animals live in a different light environment than terrestrial species. Water absorbs light so that with increasing depth the amount of light available decreases quickly.
Olivia Judson, in The Atlantic, having read Jacques-Yves Cousteau's 1973 Octopus and Squid: The Soft Intelligence, notes that Godfrey-Smith follows the neuroscientist Stanislas Dehaene in suggesting that "there's a particular style of processing—one that we use to deal especially with time, sequences, and novelty—that brings with it ...
Cephalopod intelligence is a measure of the cognitive ability of the cephalopod class of molluscs. Intelligence is generally defined as the process of acquiring, storing, retrieving, combining, comparing, and recontextualizing information and conceptual skills. [ 2 ]
These fish have a large brain size and unusually high intelligence. ... Detailed research paper on the sensory and central nervous systems in Gnathonemus petersi;
The general factor of intelligence, or g factor, is a psychometric construct that summarizes the correlations observed between an individual's scores on various measures of cognitive abilities. It has been suggested that g is related to evolutionary life histories and the evolution of intelligence [ 131 ] as well as to social learning and ...
Fish fulfill several criteria proposed as indicating that non-human animals experience pain. These fulfilled criteria include a suitable nervous system and sensory receptors, opioid receptors and reduced responses to noxious stimuli when given analgesics and local anaesthetics, physiological changes to noxious stimuli, displaying protective motor reactions, exhibiting avoidance learning and ...
The subfamily Mormyrinae contains all but one of the genera of the African freshwater fish family Mormyridae in the order Osteoglossiformes.They are often called elephantfish due to a long protrusion below their mouths used to detect buried invertebrates that is suggestive of a tusk or trunk (some such as Marcusenius senegalensis gracilis are sometimes called trunkfish though this term is ...
