Clownfish spend their entire lives nestling in the protective tentacles of host anemones, but new research shows that as babies they sometimes travel hundreds of kilometres across the open ocean. Although the process of long-distance dispersal by reef fish has been predicted, this is the first time that the high level exchange of offspring between distant populations has been observed.

Dr Steve Simpson, Senior Lecturer in Marine Biology and Global Change in Biosciences at the University of Exeter, and colleagues from the Australian Research Council Centre of Excellence for Coral Reef Studies (ARC COE CRS), Sultan Qaboos University (Oman) and the Centre National de la Recherche Scientifique (France) have published their findings on the dispersal of Omani clownfish larvae in the journal PLOS ONE.

Is Chivalry the Norm for Insects?

The long-standing consensus of why insects stick together after mating has been turned on its head by scientists from the University of Exeter.

Published in Current Biology, their study shows that, contrary to previous thinking, females benefit from this arrangement just as much as males.

Instead of dominating their female partners through bullying and aggressive behaviour, males were revealed to be protective, even laying their lives on the line when their mates faced danger.

Previously, scientists assumed that male insects stay close to females after mating to stop them from taking other partners. Female insects have multiple mates and the last mate is most likely to fertilise her eggs. Therefore, by preventing females from taking other mates a male is most likely to father her offspring.
