Informative and misinformative interactions in a school of fish [PDF]
, 2017 It is generally accepted that, when moving in groups, animals process information to coordinate their motion. Recent studies have begun to apply rigorous methods based on Information Theory to quantify such distributed computation.

A context analysis of bobbing and fin‐flicking in a small marine benthic fish
Ecology and Evolution, Volume 11, Issue 3, Page 1254-1263, February 2021., 2021 In fish, repeatedly and rapidly raising and lowering the anterior part of the body (bobbing) and repeated flicks of the dorsal, pectoral, or pelvic fins (fin‐flicking) are common behaviors often studied in the context of predation. We show that such behavioral traits can have other than an antipredator function in small marine triplefins.

Anais da Academia Brasileira de Ciências, 2018 The genera Hemigrammus and Moenkhausia have been traditionally diagnosed mainly by the former having lateral line completely pored whereas the latter having a lateral line with a few pored scales. Those features have been used to diagnose species of both

Food Habits of Five Fish Species from A Blackwater Creek in The Colombian Amazon
Mundo Amazónico, 2023 To provide baseline life history information for some of the many small fishes found in blackwater forest streams in the Colombian Amazon near the town of Leticia, we describe trophic aspects of five species of fishes.

Comparison of fish assemblages in two littoral habitats in a Neotropical morichal stream in Venezuela [PDF]
, 2008 Morichales are lowland streams in South American savannas with riparian forest dominated by the moriche palm (Mauritia flexuosa). We sampled littoral habitats from ten flooded vegetated patches (dominated by Mauritiella aculeate) and six sand banks in ...

Collective Gradient Sensing in Fish Schools [PDF]
, 2018 Throughout the animal kingdom, animals frequently benefit from living in groups. Models of collective behaviour show that simple local interactions are sufficient to generate group morphologies found in nature (swarms, flocks and mills).

A latitudinal cline in the efficacy of endogenous signals: evidence derived from retinal cone contraction in fish. [PDF]
, 2011 Like many physiological systems synchronised to the light:dark cycle, retinomotor movements in 'lower' vertebrates are controlled by both the ambient illumination and input from endogenous circadian oscillators.
