America’s great rivers are in grave peril!

Pollution, overuse, and increasingly severe weather is putting unprecedented pressures on our great rivers. America’s rivers are facing collapse that would devastate everything that relies on them.
But with enough support, we can protect our rivers and create healthy floodplains where wildlife can thrive. As the largest freshwater conservation organization in the world, we can make a real difference if we get help from people like you.
We need you on our side to help protect our nation’s great rivers, lands, and wildlife. Use the form below to pitch in and help us raise $300,000 before our June 30 deadline!

The Oriental small-clawed otter, also known as the Asian small-clawed otter, Aonyx cinerea (Carnivora - Mustelidae), is the smallest of the world’s otters.
As well as its size, the Asian short-clawed otter can be distinguished from other otters by its small claws, after which it is named, and the incomplete webbing between digits. These tiny claws, which do not protrude beyond the ends of the fingers, enhance the manual dexterity of this otter as it handles prey.
Aonyx cinerea has a large distribution, ranging from north-western and south-western India, through southern China and the Malay Peninsula, to Sumatra, Java, Borneo and the Riau Archipelago (Indonesia), and Palawan Island in the Philippines.
This species is classified as Vulnerable on the IUCN Red List, and listed on Appendix II of CITES.

Zoo Miami is home to a new litter of highly endangered Giant Otters!

The two male giant otter pups (Pteronura brasiliensis) were born on December 19 and are doing well so far. These little guys, now about two feet (60 cm) long and weighing approximately four pounds (.9 kg), will be truly giant as adults. They may grow to be nearly six feet (1.8 m) long and weigh close to 75 pounds (34 kg)!

Sea Otters May Help Combat Harmful Runoff Pollution Off the California Coast
by Jaymi Heimbuch
As a keystone species, the importance of sea otters for the health of coastal ecosystems can’t be understated. A new study shows that they may even play an indirect but key role in helping coastlines cope with agricultural run-off.
The study by University of California, Santa Cruz, published in mid-August, shows that by eating crabs, sea otters are helping sea grasses thrive even in the face of pollution…

The Sea Otter (Enhydra lutris)
… is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. These animals inhabit offshore environments, and dive to the sea floor to forage for invertebrates such as sea urchins, molluscs and crustaceans. Female sea otters provide all the parental care for the young. They have two abdominal nipples, and float on their backs to nurse their pups. While the mother is foraging, the pup will remain on the surface. It will start diving after two months. It learns from its mothers how to forage and what prey items to look for.

Marine Otter (Lontra felina)

…a rare species of otter that occurs along the coast of western South America, from northern Peru to Cape Horn and Isla de Los Estados. Like its common name suggests L.felina spends most of its life out in the ocean, however it also inhabits freshwater and esturarine habitats as well unlike the Sea Otter (E.lutris). Like sea otters marine otters are nimble in the water and will dive for fish, cephalopods, crustaceans and molluscs. It will emerge from the sea to rocky islets to rest and eat, individuals will claim rocks and will defend them from other otters. Despite this, they are not territorial and they have even been seen fishing cooperatively.

Lontra felina is currently listed as endangered by the IUCN, and faces threats from hunting for its pelts and habitat loss. Its also threatened by water pollution and over-fishing of its prey species.

Marine Otter (Lontra felina)

A lesser known member of the otter family, the marine otter prefers the sea over fresh water rivers and estuaries.  It bears more resemblance to the river otter, but lives and behaves more like a sea otter.  They are smaller than most otters, reaching a total length of up to about 3.5 feet.  Their fur is coarser and shorter than sea otters. 

Unlike most otters, they prefer areas with intense winds and heavy waves, and avoid sandy beaches.  They live on the rocky shores of Argentina, Peru and Chile.  Their diets consist mostly of fish, crab and mollusks.  Their teeth are more adapted to cut rather than crush. 

Hunted for their fur, they were nearly wiped out, but today have slowly recovered under government protection.  They are listed as endangered.
