The dolphin (here Bottlenose dolphin) is a marine-mammal well-known for its cleverness, cheerfulness and compassion for human beings (There are lots of stories about sinking people saved by dolphins) as much as for its complex language based on ultrasound. Studies about dolphins proved that they could recognise themselves in a mirror (Self-conscience) and are able to use tools (and learn how to). It’s interesting to know that dolphins belong to those rare animals pairing for other reasons than reproduction. Dolphins seem to be more or less the highest part of animals’ evolution. High Five
