How often do we get to see a great ray in its natural habitat, especially in Europe. Here, you could visit an Italian nature reserve and get to know animals that compare with the giant mantas (almost.)
It isnt just about apes. The whole study of animal society has been based on dogs, cattle and others such as our close relatives. Social behaviour undoubtedly began in another mammal group, even if it then became extinct. Investigating such behavioural structures has apparently totally neglected the very obvious, early small mammals that could well have advanced at least to the primate level, and we even left out the small species still here for us to observe.
When dolphins are 'rescued' in various countries, the car given seems to be ill-considered. We are simply looking at the success rate which is reported to be low, in most places. They could even end up in commercial aquarium shows, but they certainly rarely make it back to the sea.
