The
other day while we were out at Capella Bay near Buck Island, some of
our divers got a rare treat! A big Hawksbill sea turtle with a REALLY
long tail swam by. None of them had ever seen a turtle like this
before. Only male sea turtles have a really long, beefy tail.

The females have a much shorter tail, mostly hidden beneath their shell. This is the most obvious distinguishing characteristic that helps us identify a male from a female sea turtle.
Why is this such a rare sighting? We see sea turtles relatively often (considering they are endangered species)
, but over 99% of the time we are looking at female sea turtles. So
where are all of the males hiding? Male sea turtles spend most of their
lives out in open ocean. Believe it or not, life is safer for turtles
out there. But why? There is a much higher population density in the
near coastal environments. In open ocean, creatures are so spread out
that their chances of running into a predator are much less than in the
coastal areas. Male sea turtles only visit the near coastal areas to
mate with the females and then head back out to open water.

The
female sea turtles have to take the risk of coming into the near
coastal areas so they can feed. They need to consume lots of calories
to get big and strong, because when they are mature they will have to
produce over 100 eggs each time they nest. Female sea turtles nest
multiple times per season. That requires a lot of energy!
A
huge "THANK YOU!" to our friend and local diver Jason Crump for
capturing footage of this rare sighting of a male Hawksbill sea turtle
and allowing us to share it!
