Instinct. Instinct is the inherent inclination of a living organism towards a particular complex behaviour, containing innate (inborn) elements. The simplest example of an instinctive behaviour is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a ...
Aquatic locomotion. Aquatic locomotion or swimming is biologically propelled motion through a liquid medium. The simplest propulsive systems are composed of cilia and flagella. Swimming has evolved a number of times in a range of organisms including arthropods, fish, molluscs, amphibians, reptiles, birds, and mammals .
Fish intelligence. 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. Due to a common perception amongst researchers that Teleost fish are "primitive" compared to mammals and birds, there has ...
In sum, a fish has an advantage if it is in the larger of two groups, assuming that the probability of detection and attack does not increase disproportionately with the size of the group. Schooling forage fish are subject to constant attacks by predators. An example is the attacks that take place during the African sardine run.
This is a list of Asian animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [a] and continues to the present day. [1] This list includes the Asian continent and its surrounding islands, including Cyprus. The three Transcaucasian republics ...
Celestial orientation, navigation using the stars, is commonly used for homing. Displaced marbled newts, for example, can only home when stars are visible. Olfaction. There is evidence that olfaction, or smell, is used in homing with several salamanders, such as the red-bellied newt. Olfaction is also necessary for the homing of salmon.
The novel object recognition (NOR) test is an animal behavior test that is primarily used to assess memory alterations in rodents. It is a simple behavioral test that is based on a rodents innate exploratory behavior. The test is divided into three phases: habituation, training/adaptation and test phase.
Self-preservation is a behavior or set of behaviors that ensures the survival of an organism. [1] It is thought to be universal among all living organisms. For sentient organisms, pain and fear are integral parts of this mechanism. Pain motivates the individual to withdraw from damaging situations, to protect a damaged body part while it heals ...
