Spotted eagle ray

This ray was spotted in our harbor at the end of January (pun unintended).
Rays are related to sharks and sometimes are called "pancake sharks". They are not aggressive and just ignore people if we happen to swim by.
Sometimes they jump high up in the air... why they do it? there is a version about getting rid of the parasites this way. Anyways, it looks breathtaking.
Someday, maybe, I'll be lucky enough to take a picture.
