Mantas are an important indicator of the health of the ocean realm. Mantas play an as yet unquantified role in the ecological function of our oceans. As consumers of large quantities of photosynthetic phytoplankton, they may help to transfer atmospheric carbon to the deep ocean, regulating climate change.

Why are manta rays so important?

WHY THEY ARE IMPORTANT

They control plankton abundance and diversity and regulate nutrient cycling. Reef manta rays dive between the surface ocean and the deep sea, creating a valuable ecological connection between the two.

Are Mantas intelligent?

Mantas have huge brains — the biggest of any fish — with especially developed areas for learning, problem solving and communicating. The giant rays are playful, curious and might even recognize themselves in mirrors, a sign of self-awareness.
