As mentioned before, whale sharks, manta rays, and a ton of sharks are common in Galapagos. But here are some more we haven’t mentioned yet.
Sea lions are very playful and will swim around you while you dive.
There are also sea turtles, which are normally found in slightly deeper waters. These sea creatures have very protective shells, but unlike normal turtles they can’t retreat back into them. Sharks have been known to crack through one, but their shells sure do put up a fight.
There are 5 kinds of dolphins there, but only 2 live year round: the bottlenose dolphin and the common dolphin. The others almost only show up for migrating seasons.
The silky shark and whitetip reef sharks can be seen too. The whitetip can grow up to 5.3 feet and is known for sticking low at the bottom of the coral reefs. The biggest silky shark ever was 3.5 meters (11 feet) and 346kg, but most are only 2.5 meters (8.2 feet).
Whitetips are practically harmless, unless you steal their food, in which they might nip at you. Silky sharks, on the other hand, can be potentially dangerous but mostly not. Remember: sharks will usually only attack if you attack them, but sometimes they mistake you for seals because your fins have a resemblance to their flippers from a distance away when they only see your silhouette.
All kinds of eels can also be seen, and many different types of them too.
