THE MANTA RAY: You could be saving the oceans, one photo at the time.

This gentle sea giant, as its name points out, is a type of ray; the biggest ray of all, up to 7m in diameter.

Several factors allow us to differentiate them.

Reef mantas tend to be smaller and have a different back pattern than the giant manta. They also have different tails. At the base of the giant manta sits a more pronounced bulge that scientists suspect to be the remains their previous stings, now gone, making the manta ray completely inoffensive.

Finally it is also possible to distinct the gender. Their reproductive organs sit just under their pelvic fins and are fairly easy to distinguish; the male will have not one but two penis like organs called claspers. The female only possesses a slit.

Beyond the simple beauty of these creatures, taking those photos will as divers ensure we are trying to do our best to protect the species in our oceans.
