SYDNEY, March 21 (Bernama) -- A small fish that lives in the Australian Great Barrier Reef preys on smaller fish by changing colour and pretending to be an adult of their own species, a study showed Friday.
The dusky dottyback (Pseudochromis fuscus) is a small predatory fish found throughout the Indo-Pacific and has the ability to be able to change colour.
Its ability to vary in colouration has baffled scientists until an international research team led by evolutionary biologists Dr Fabio Cortesi and Professor Walter Salzburger from the University of Basel have developed a theory.
The zoologists are now able to show that dottybacks can quickly change their colour in order to mimic other fish species and chase their prey.
The dusky dottyback fish also helps protect it from its own predators.....
