:''Common names: Amazon tree boa, macabrel, Cook's tree boa, common tree boa, garden tree boa.〔Mehrtens JM. 1987. Living Snakes of the World in Color. New York: Sterling Publishers. 480 pp. ISBN 0-8069-6460-X.〕'' ''Corallus hortulanus'' is a non-venomous boa species found in South America. No subspecies are currently recognized.〔 ==Description== Adults grow to an average of 5 and 6.5 feet (1.5–2 m) in length.〔Burnie D, Wilson DE. 2001. Animal. Dorling Kindersley. 624 pp. ISBN 0-7894-7764-5.〕 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. Generally, there are two color 'phases' that are genetically inherited, but are not ontogenic as with the emerald tree boa,''C. caninus'' and the green tree python, ''Morelia viridis''. The 'garden phase' refers to boas with drab coloration, mostly brown or olive, with varied patterning, while the 'colored phase' refers to animals with combinations of red, orange, and yellow coloring.
