What is the characteristic base coloration of the yellow anaconda, *Eunectes notaeus*?
Answer
Bright yellow to yellowish-brown
The yellow anaconda, *Eunectes notaeus*, is distinguished from its greener relatives by its lighter base coloration, typically manifesting as a bright yellow or yellowish-brown hue across its body. This base color is further characterized by the presence of dark, rounded blotches that run along its back. This specific coloration pattern provides crucial camouflage within its natural environment, allowing it to blend effectively among the submerged vegetation, the muddy bottoms of wetlands, and the shaded waters characteristic of the floodplains it inhabits in central and southern South America.
