I worked with giant manta identification to differentiate each individual, and thus evaluate their population. This helps to obtain important information including how many individuals are in the biosphere reserve, how many mantas are present every season and if there are new mantas every season. It also includes which islands attract more mantas, how many females and males are there, and how the mantas move between the islands.

The highlights had to be up close and personal encounters with sea lions and a school of 30-40 mobula rays right above my head! This is the biggest school I have ever seen in 10 years diving and I hope there will be more schools to see later in the trip!

On the other dives we were watching sea lions and the fish life that has definitely been showing the effect of protecting this as a park. Snappers and Groupers are much bigger and in larger groups. We are also seeing much more of the grown up Bumphead parrot fish than ever before. Two days in the Sea of Cortez with flat sea and a different sea than where we are going, a very rich “Fishy sea.”
