Giant Otter - Pteronura brasiliensis The giant otter (Pteronura brasiliensis) is a South American carnivorous mammal. It is the longest member of the Mustelidae, or weasel family, a globally successful group of predators. Unusually for a mustelid, the giant otter is a social species, with family groups typically supporting three to eight members. he giant otter shows a variety of adaptations suitable to an amphibious lifestyle, including exceptionally dense fur, a wing-like tail, and webbed feet. The species prefers freshwater rivers and streams, which are usually seasonally flooded, and may also take to freshwater lakes and springs. It constructs extensive campsites close to feeding areas, clearing large amounts of vegetation. The giant otter largely subsists on a diet of fish, particularly characins and catfish, and may also eat crabs. It has no serious natural predators other than humans, although it must compete with other species, including the Neotropical otter and caiman species, for food resources. The giant otter is clearly distinguished from other otters by morphological and behavioural characteristics. It has the greatest body length of any species in the mustelid family, although the sea otter may be heavier. Males are between 1.5 and 1.7 m (4.9 and 5.6 ft) in length from head to tail and females between 1 and 1.5 m (3.3 and 4.9 ft). The animal's well-muscled tail can add a further 70 cm (28 in) to the total body length. Early reports of skins and living animals suggested exceptionally large males of up to 2.4 m (7.9 ft); intensive hunting likely reduced the occurrence of such massive specimens. Weights are between 26 and 32 kg (57 and 71 lb) for males and 22 and 26 kg (49 and 57 lb) for females. ![]() Giant Moray - Gymnothorax javanicus The giant moray is the largest of the Moray eels, in terms of body mass (the slender giant moray is longer).The giant moray is widespread in the Indo-Pacific region, being found in the Red Sea and East Africa, the Pitcairn group, north to the Ryukyu and Hawaiian islands, south to New Caledonia, Fiji and the Austral Islands. As the name suggests, this is a large eel, reaching up to 300 cm (10.0 ft) in length and 30 kg (66.1 lbs) in weight. While juveniles are tan in colour with large black spots, adults have black specks that grade into leopard-like spots behind the head and a black area surrounding the gill opening. Diet: Primarily crustaceans. Habitat: Found in lagoons and seaward reefs. ![]()

Yes you are, as long as the photos don't depict animal cruelty ( i.e. things like baiting and the such). If you have some, I would also love to see some videos of swimming eel, to have an idea of their agility and speed, what I found on youtube so fare wasn't particular impressive, especially compared to what the otter is able to do. ...and welcome to the forum!

Thanks! Just looking at the skull, its pretty easy to see the teeth and assume the bite would be like a snake or something, but it isn't. Heres a picture of a guy who got his arm chomped on by a decent sized moray. http://www.wetwebmedia.com/ca/volume_5/volume_5_2/images/moraysimages/03.jpg and for size reference, here it is a year later after reconstructive surgery and whatnot. ![]() The eel that did that was nowhere near the size of the theoretical 10 footer that was mentioned in the OP. I've also seen a moray that was only around three feet long almost remove someones finger. I can't find a great video of a moray swimming quickly, but they're capable of it if they want to. They don't see well though, so wouldnt be able to really chase anything. (and wouldn't come out of their hole anyway) its also worth noting that moray eel bites are well known for getting infected very easily, and that they are venomous, and sometimes also poisonous. They're pretty ridiculous animals. |

http://www.youtube.com/watch?v=JenbH-hiBDQ Takes his thumb off, mind you - an otter could replicate that easy enough. At average weights the otter's too big for the eel I think. Plus an eel is more prey-like to an otter than vice versa |
