Abstract:
A new study with cleaner fish demonstrates the need to expand cognitive testing of animals beyond success testing (a simple pass or fail criteria), and instead investigate the signatures of how animals solve tasks. By tailoring traditional cognitive tests to the focal species' natural behaviour, researchers can provide animals with a better chance for demonstrating their cognitive abilities, offering a more comprehensive understanding of the evolution of cognition.

When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.
