What a difference an ear makes
Article Abstract:
Fur seals, sea lions, walruses and true seals all belong to the aquatic mammals known as pinnepedia, which means fin-footed, referring to the characteristic flippers at the end of their limbs. True seals lack external ears, have non-rotating rear flippers and are unable to lift themselves from the ground. Sea lions and fur seals have external ear flaps, rotating hind flippers and are capable of far more agility on land. All have a body shape that is streamlined for swimming. The walrus, which constitutes its own family within the pinnepedia, can weigh 3,000 lbs and has long canine teeth called tusks.

Biodiversity in Puerto Rico
Article Abstract:
The islands that make up the Commonwealth of Puerto Rico contain a wide range of habitats, thus ensuring that Puerto Rico has great diversity of plant and animal life. Some 5% of Puerto Rico is protected as public forests or reserves managed by the US Forest Service (Caribbean National Forest) and the Puerto Rico Dept of Natural and Environmental Resources, as land protected by non-governmental organizations and as refuges managed by the US Fish and Wildlife Service. The native flora of Puerto Rico is made up of around 3,000 species, while the native avifauna includes 239 species.

On the slopes of Puerto Rico's Luquillo Mountains, Iguaca makes its last stand
Article Abstract:
The Puerto Rican parrot is making a comeback through the extensive aid of wildlife biologists but it remains one of the ten most endangered birds worldwide. Some 72 in captivity supplement fewer than 50 in the wild, all living in the Caribbean National Forest. More than a million once inhabited the island. The birds are the smallest West Indies parrots, rarely reaching 12 inches in length, and nest in palo colorado trees. They stir fierce political passions in Puerto Rico, which has suffered so much from invaders.
