In this nonfiction book for middle-grade readers, uncover the mysteries of manta rays, including their biology, aquatic habitats and environmental threats.

Less than twenty years ago, people knew almost nothing about the elusive manta ray. Scientists have since discovered that manta rays have the largest brain-to-body ratio of all fish, which makes them smart and social. More importantly, manta rays bring nutrients to coral reefs, helping create connections between shallow and deep seas. Their smooth, sweeping movements have even inspired technology for underwater robots and spacecrafts that may one day fly around the planet Venus!

As scientists continue to study manta rays, they are also learning how much they need our help. The more people know about manta rays, the more we can work together to make a difference. So grab your wetsuit and goggles--and let's dive with the rays!
