Giant River Otter

Pteronura brasiliensis


The Giant Otter or Giant River Otter is one of the most endangered species of South American mammals. I photographed this individual along the Cuiaba River in the northern Pantanal. It was enjoying its meal of a freshly caught fish and squealing with delight - these social animals are very noisy.

Fantastic spotting & picture. You are so lucky, we looked for 3 days (near Puerto Maldonado) and didn't get remotely close to them.

ok, this one should definitely get looked at for a spotting of the day or week...your image quality is fabulous and the subject matter is very neat. I love his little tongue licking his mouth. Very cool.

Thanks for the positive comments - it was a fantastic sighting! Unfortunately I don't know the species of fish so can't help with that!

From Wikipedia:

Members of the family Loricariidae are commonly referred to as suckermouth armoured catfishes, armoured catfish, 'plecos' or simply 'plecs'; a shortened form of the species name plecostomus.

These names are used practically interchangeably when referring to the Loricariidae. The name "Plecostomus" and its shortened forms have become synonymous with the Loricariidae in general, since Plecostomus plecostomus (now called Hypostomus plecostomus) was one of the first species imported into the fishkeeping hobby. This can cause some confusion as some unrelated fish may also be called plecostomus, such as the "Borneo Plecostomus", which are actually balitorid fishes.

Definitely a spotting of the day--it's wonderful.

I thought it looked like something in the "Plecostomus" family. :-D

future sotting of the day perhaps

The fish seems to be a "Cascudo", a Loricariidae, Order Siluriformes. That name means, in portuguese, "shelled", for its hard skin, covered with bony plates.
