Mortela Island

Mortela Island is an island three times the size of Catalina Islands that is off the east coast of Costa Rica. It is also known as the "Dylanus's Paradise" due to lack of predators or dangerous animals (such as deadly spiders, insects, etc), lack of competition (from apes, monkeys, etc), and has abundance of food (fruits, insects, fish, frogs, eggs, small mammals, etc). Despite this, dylanuses and (most) other nonnatives have no known negative impact as (almost) all native species are used to many (if not all) nonnative species.
