At the sea of Galapagos, El Niño flows (of warm waters) and the Humboldt current (of cold waters) converge. These conditions allow the development of at least 307 species of fish, of which 25 percent is endemic.

The food chain of the sea of Galapagos begins with the spineless ones whose habitat is the lava. The small fish live in the cracks surrounded by the big fish and present a great variety of colors.

In the bottom of the ocean the mantarrayas slip, while in the surface they surprise with their jumps. This species is common in warm waters, they feed of plankton and small fish.

The mantarrayas move in groups of thirty and in Galapagos can be located around the Floreana and Isabela Islands.
Inside the marine wealth we also find jellyfishes, sponges, mollusks and crabs. The most impressive is the "Slight feet Sally" crab of orange color that can be found in the rocks.
Some cetaceans like dolphins, whales and porpoises can be appreciated in migratory times. Among them, it is the orca and the white dolphin.
