Frequency dependent cichlid

The original fequency dependent cichlid fish paper is in Science:
Frequency-Dependent Natural Selection in the Handedness of Scale-Eating Cichlid Fish.

It looks like this common text book story is true. The figure nicely illustrates that having a neat story isn't enough to get your paper into Science but having ten years of data to back it up will do the trick.

Fish that uses mirrors to see

Random cool animal: the brownsnout spookfish uses mirrors to focus light into its eyes. It is apparently the first vertebrate to do this. A live specimen had never been caught until last year, when one was caught off Tonga.
