Forests can be found all over the world, including underwater! Giant kelp forests grow in coastal waters where the water is very clear so sunlight can reach the sea floor. Kelp can grow up to 18 inches a day if the conditions are right, meaning kelp forests can spring up quickly!

Undersea Encounters paints a more complete picture of marine life, including books on habitats and animal behaviors in addition to specific animal books.

This up-close look at a fascinating scientific discovery highlights the critical role predators such as sea otters play in keeping ecosystems healthy. In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water. This healthy seagrass baffled marine biologist Brent Hughes. The scientist expected this estuary to be overrun with algae, causing the seagrass to die. Why was the seagrass thriving? As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain? Brent's amazing discovery gave scientists insight into the delicate balance of ecosystems.
