Spectacled Caiman - Caiman crocodilus
The spectacled caiman (Caiman crocodilus), also known as the white caiman or common caiman, is a crocodilian reptile found in much of Central and South America. It lives in a range of lowland wetland and riverine habitat types and can tolerate salt water as well as fresh; due in part to this adaptability it is the most common of all crocodilian species. Males of the species are generally 2 to 2.5 metres (6.6 to 8.2 ft), while females are smaller, usually around 1.4 metres (4.6 ft). They mainly weigh up to 40 kg (88 lbs). The species' common name comes from a bony ridge between the eyes, which gives the appearance of a pair of spectacles. They have been known to change color. During colder weather the black pigment, found within their skin cells, will expand making them darker.
North Pacific Giant Octopus - Enteroctopus dofleini
Enteroctopus dofleini, also known as the Giant Pacific Octopus or North Pacific Giant Octopus, is a large cephalopod belonging to the genus Enteroctopus. It can be found in the coastal North Pacific, usually at a depth of around 65 meters (215 ft). It can, however, live in much shallower or much deeper waters. It is arguably the largest octopus species, based on a scientific record of a 71 kg (156.5 lb) individual weighed live. The alternative contender is the Seven-arm Octopus based on a 61 kg (134 lb) carcass estimated to have a live mass of 75 kg (165 lb). However, there are a number of questionable size records that would suggest E. dofleini is the largest of all octopus species by a considerable margin. E. dofleini are distinguished from other species by their sheer size. Adults usually weigh around 15 kg (33 lb), with an arm span of up to 4.3 m (14 ft). However, there are highly questionable records of specimens up to 272 kg (600 lb) in weight with a 9 m (30 ft) arm span. The mantle of the octopus is spherical in shape and contains most of the animal's major organs. By contracting or expanding tiny pigment-containing granules within cells known as chromatophores in its tissue, an octopus can change the color of its skin, giving it the ability to blend in to the environment.
