There are 3 different rays in the mobula family there is a devil ray which is my favourite one and there are two manta rays the small one is called alfredi and the big one is called Birostris . we know a lot about manta rays but very littel about devil rays.
every mobula ray eats plankton and other tiny tiny tiny things that then go to the gill rakers which colects all the small things then it shuts its mouth and coughs it back up and swallows .
It uses it's cephalic fins to channel food into it's mouth.
We have seen Alfredi and Devil Rays and the Devil Rays that we saw in St Helena in the Atlantic Ocean were super friendly. They would come to our boat and swim around with us for hours at a time. It felt like they were copying and following us and that they were curious about us.
We named this one Lucy.
Both manta and devil rays dive really, really deep. Scientists put trackers on their backs to find out how deep they go. They found that a devil ray swam down to 1.5km deep!
Manta ray mating is triggered by the full moon. When mantas are mating the male swims close behind the female and the male will grab onto the females pectoral fin with its mouth and will flip himself upside down and touches her belly and release his sperm. After that they may stay or they may leave each other. Other males may come as well to try to get a mate.
Check out this video - the story is about a lost Manta Ray.
.The chines use manta gillsfor currying cansa but no one nose if it works.
