While most tiger species avoid humans, this tiger is notorious for actively hunting humans, a trait that has earned it the name man eater. Although for a time, fear of the creatures and the inaccessibility of their chosen habitat protected the tigers from human poaching, recent sea level rise is now threatening their existence.

When all plants that live in a mangrove environment are accounted for, there are well over 80 mangrove species. Official websites use .gov Other organisms rely on the structures created by the branching trees and their tangle of roots. Some creatures are found nowhere else but in mangrove forests.
