Other interesting creatures we saw in the Sea of Cortez were rays, the very large Manta Ray (Manta birostris):
and Smooth-tailed Mobula Rays (Mobula thurstoni), a much smaller version of the Manta Ray:
In the above image, you can see Mobula Rays feeding on krill at the surface. The small, pinkish “flecks” are the krill jumping about.
Above, a Mobula Ray jumps out of the water, an interest phenomenon that we saw quite often.
