What is a coral reef actually made of? What microscopic creatures take shelter in the coral and become its food? Which coral reef resident has stinging tentacles? And which huge creature visits the reef to have its dead skin and parasites nibbled away by a fishy clean-up crew? Packed with facts, core-curriculum information, and fantastic photographs that support the text, this title takes readers on a mini safari around a coral reef. Like piecing together a jigsaw puzzle, readers will discover how the living things that make this habitat their home depend on each other and their environment for survival.
