Fish May Be Smarter Than We Think They Are…

Plenty of previous research has shown that highly social birds and mammals cooperate while feeding, but that behavior had never before been seen in fish. In fact, many thought it was impossible for fishes. But now we know the truth.

New research from the ARC Centre of Excellence for Coral Reef Studies at James Cook University reveals that pairs of rabbitfish “cooperate and support each other while feeding”.

The pairs coordinate their activity “quite strictly”.

“One partner stays ‘on guard’ while the other feeds – these fishes literally watch each others’ back,” Dr Simon Brandl explained in a news release. “This behaviour is so far unique among fishes and appears to be based on reciprocal cooperation between pair members.”

Reciprocal cooperation is the key here. The idea of reciprocation requires complex social skills that fishes are not typically associated with.

“There has been a long standing debate about whether reciprocal cooperation can exit in animals that lack the highly developed cognitive and social skills found in humans and a few species of birds and primates.” said Dr. Brandl.

“By showing that fishes, which are commonly considered to be cold, unsocial, and unintelligent, are capable of negotiating reciprocal cooperative systems, we provide evidence that cooperation may not be as exclusive as previously assumed.”

While fascinating from a scientific standpoint, this study may also have ethical implications. If some fish are capable of complex social interactions, will we need to change how we study them?
