Mobula Rays in the gap between Isla Partida and Espririto Santos Island near La Paz, Baja Sur Mexico. We swam with this large group of hundreds of animals. Slow moving group that we are able to bring a sailboat up next to.
Manta Rays observed very close to rocky shoreline near Mauna Kea Beach Hotel. Hotel turns on light at night to attract rays to the shoreline for visitors to watch. Rays about four feet wide.
The dive spot is called Manta Sandy. GPS coordinates are not spot on.

It was big (i'd estimate ~3m) but far and in deep (>30m) cloudy water. This is the only more or less acceptable picture.
