The spectacled caiman is a Small to medium-sized crocodilian. Males of the species are generally 1.8 to 2 m, while females are smaller, usually around 1.2–1.4. The body mass of most adults is between 7 and 40 kg. The maximum reported size for the species is 2.5 m , with a body mass of 58 kg but they can growing up to 3 m in length potentially. The species' common name comes from a bony ridge between the eyes, which gives the appearance of a pair of spectacles. Juvenile spectacled caimans are yellowish in color, with black spots and bands on the body and tail. As an individual matures, it becomes more olive-green, and the markings become less distinct. Interestingly, this species may have some ability to change color The spectacled caiman is a superbly adapted aquatic predator. Most feeding activity takes place during the wet season, with juveniles feeding mainly on insects, crustaceans and snails, while adults take fewer insects, but also take fish, amphibians, reptiles and water birds, I personally have seen a caiman feeding on another caiman, but I couldn’t see the caiman killing the other individual
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
also known as the white caiman or common caiman.
