Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane , such as modern reptiles , birds and mammals ).
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 ]

In a consumer behaviour context, vicarious learning which involves changing behaviour by having an individual observe the actions of another and witness the consequences of that behaviour, is used to develop new responses and inhibit undesired behaviours. The former is done through educating consumers in product uses i.e. through product ...

Greater siren out of water. Greater sirens are carnivorous and prey upon invertebrates (such as insects, crustaceans, gastropods, bivalves, spiders, molluscs, and crayfish) [11] and aquatic vertebrates (such as small fish) [11] with a possible preference for molluscs (such as snails and freshwater clams), [8] [12] although they have been observed to eat vegetation such as algae.
Linnaeus, working from species-poor Sweden, where the common adder and grass snake are often found hunting in water, included all reptiles and amphibians in class "III – Amphibia" in his Systema Naturæ. [8] The terms reptile and amphibian were largely interchangeable, reptile (from Latin repere, 'to creep') being preferred by the French. [9]
In captivity, the predatory behavior amphiuma display depends on the presence or lack of food. Amphiuma will remain inactive when food is absent, and will become more active once food has been introduced into their habitat. [12] This shows that the amphiuma, although ancestral to many amphibia, has developed a deductive approach to its predation.
