the eye of a Nile crocodile
That’s a shark’s brain. Looks oddly familiar, doesn’t it?
Is it just me, or have dolphins been the original “mona lisa smile-rs”? Seriously.
is a non-venomous boa species found in South America.
This species exhibits an immense variety of colors and patterns. The basic color can be anywhere from black, brown, or gray, to any shade of red, orange, yellow, or many colors in between. Some are totally patternless, while others may be speckled, banded, or saddled with rhomboid or chevron shapes. Some reds will have yellow patterns, some yellows red or orange patterns.
These animals are notorious for being very aggressive, although as with all snakes this varies. These animals also have very long needle-like teeth which makes their bite quite painful. However these snakes tend to give some warning of being inclined to bite, and will usually give fairly gentle bites (which can still draw blood) unless they are given reason to give a full on strike, at which point the person concerned will have intimate first hand knowledge of the 20 or so teeth an adult Amazon Boa has available to it.
The aggressiveness is in part due to the species feeding cycle. The snakes are night time hunters, so they are in hunting mode when they are most likely to be handled by an owner. Being in a hunting mood and being that an owners hands are usually nice, hot and prey sized (Amazon Boas hunt mainly using their heat sensors) - people do get bitten, although as with most snakes, the animal will soon realise their mistake and let go, since they can recognise the smell of their owner. It is uncommon for a constrictor snake that knows the person handling it to strike and constrict the person, as they would a food item, unless the snake is very agitated.
