Descend onto the sandy bottom where currents bring pelagic visitors.
Common encounters include:

- Reef fish
The open sandy terrain makes marine life easy to spot.
Highlight: Watching rays glide across the seabed.
One of Mosquera’s signatures is its dense population of endemic garden eels, which extend from the sand in massive colonies.
This creates a surreal underwater landscape rarely seen elsewhere in the Galapagos.
Highlight: Thousands of eels swaying in the current.
During the second immersion, divers often encounter:
- White-tip reef sharks
- Blacktip reef sharks

A highly satisfying Galapagos dive…
without the stress of the most extreme sites.
