Possibly, the most intriguing aspect of Las Secas is the abundance of fauna on the islands and in the region. Functioning as a protected habitat for a number of animal species, the islands have become an exquisite place to observe these creatures in their natural living environment. Some of the more rare animals include:

• Four species of sea turtles (Green, Leatherback, Hawksbill, Olive Ridley)
• Hump-backed and Orca whales
• Birds – a variety of hummingbirds, raptors, sea birds, and neotropical
