Coming back from Moreton this week passed some odd floaters that on closer inspection turned out to be turtles. ..about 60cm just sitting there. Got so close that could have picked one of them up. Only stopped because I thought maybe something was wrong but all 3 were the same and spread over 2 nm. They looked OK, just so used to them diving I thought it wierd.
Maybe just enjoying the glassy sea and the warm sun?
