Numerosity discrimination, the ability to distinguish between sets with more and less items, is recognised as the foundation for higher numerical abilities. Understanding numerosity discrimination from a comparative perspective is hence pivotal in tracing the evolution of numerical representation systems. However, numerosity discrimination has been well studied only in vertebrates, where two innate systems of number representation have been described: an ‘analog magnitude system’ used to… 
Quantity discrimination in salamanders
TLDR
Analysis of the salamander' success and failure as well as analysis of stimulus features points towards movement as a dominant feature for quantity discrimination in salamanders.
Large quantity discrimination by North Island robins (Petroica longipes)
TLDR
The results suggest that cognitive mechanism influencing an understanding of physical quantity may be deployed more flexibly in some contexts than previously thought, and are discussed in light of findings across other mammalian and avian species.
A sense of number in invertebrates.
Numerical discrimination by frogs (Bombina orientalis)
TLDR
It is suggested that task demands are likely to be responsible for the activation of different systems for small and large numerousness and for their relative susceptibility to quantitative stimulus variables.
Can angelfish (Pterophyllum scalare) count? Discrimination between different shoal sizes follows Weber’s law
TLDR
Angelfish are able to discriminate between different quantities of conspecifics subject to a ratio limit, a finding that implies a fitness component in this behaviour similar to what has been demonstrated in higher order vertebrates.
Counting on Numbers—Numerical Abilities in Grey Bamboo Sharks and Ocellate River Stingrays
TLDR
The high degree of intraspecific variation that was observed as well as the low rate of animals proving to be successful suggest that the ability to discriminate quantities may not be as important to these species as to some other vertebrate and invertebrate species tested so far.
Non-visual numerical discrimination in a blind cavefish (Phreatichthys andruzzii)
TLDR
Cavefish trained from the beginning only with stimuli controlled for continuous quantities proved able to learn the discrimination of quantities based on the sole numerical information, however, their numerical acuity was lower than that reported in other teleost fish tested with visual stimuli.
Quantitative cognition in carpenter ants
TLDR
It is shown that carpenter ants use both relative quantity and relative position to make efficient decisions, which suggest that ants might use quantitative information to make optimal choices in their natural environment although the precise mechanisms underlying this ability should be further investigated.
Numerical competence in animals, with an insight from ants
TLDR
It is suggested that applying ideas of information theory and using the natural communication systems of highly social animals can open new horizons in studying numerical cognition.
Numerical Cognition in Bees and Other Insects
TLDR
This review article presents the main experimental studies that have examined the ability of insects to use numerical information and suggests avenues of further research that take into account variables such as the animals’ age and experience, as well as complementary cognitive systems such as attention and the time sense.

Discrimination of the larger shoal in the poeciliid fish Girardinus falcatus
TLDR
This work investigated the spontaneous choice for the larger of two shoals in female goldbelly topminnows and compared two different methods to determine an efficient procedure for studying the numerical competence of fish and found that when groups differed in size by one individual, choice of the larger shoal was significantly above that predicted by chance.
Discrimination of relative numerosity by pigeons
In three experiments, pigeons were trained to discriminate between uniform arrays of two elements that differed in color, form, or size. They were then tested with arrays that contained different
Origins of Number Sense
TLDR
Nine-month-old infants, in contrast, successfully discriminated 12 from 8 sounds, but not 10 from 8Sounds, providing evidence that numerosity discrimination increases in precision over development, prior to the emergence of language or symbolic counting.
Cognition in Invertebrates
Individual recognition by scent
TLDR
The cue characteristics necessary to code individuality reliably are discussed, and the bioassays that have been used to assess individual recognition ability are reviewed.

DENSITY DEPENDENCE AND NUMEROSITY IN FRIGHT STIMULATED AGGREGATION BEHAVIOUR OF SHOALING FISH
TLDR
Three-spined sticklebacks were frightened with a light stimulus simulating an aerial predator while facing a choice between two conspecific display shoals of different membership sizes and it was found that stickleback made a trade-off between the distance to a display shoal and its membership size.

Rudimental numerical competence in 5-day-old domestic chicks (Gallus gallus): identification of ordinal position.
TLDR
Overall, young chicks seemed to use ordinality when required to identify a target by its numerical serial position in a series of 10 identical positions.
Salamanders (Plethodon cinereus) go for more: rudiments of number in an amphibian
TLDR
The findings indicate that salamanders "go for more," just like human babies and monkeys, which is a type of numerical discrimination that is spontaneously present in this amphibian.
