tidepool goby

Bathygobius cocosensis
Not only will fish remember the smell of a predator that has attacked it, this goby can memorise the layout of separated rock pools (by swimming over them in high tide) and will leap from one to another without being able to see the next one.
On top of this if you removed this fish from its territory it would act like a homing pigeon and find its way home.
