Manatees, Gentle Giants in Peril

These passive sea cows have been enjoying the warm waters of the earth for millions of years, grazing on water plants. Unfortunately, their numbers are diminishing, as they suffer from loss of habitat, assaults by boat propellers, and entanglement in fishing line and other human debris. This book chronicles their life history, threats to their continued survival, and positive steps being taken to protect them from extinction. 1995 Revised Edition - Paperback 48 pages, line illustrations. Size 5.5 inches x 8.5 inches, by Mary Unterbrink.
