Condocho
A type of fish found in the streams of the Quibor region in Lara State. It is thin, elongated, and 8 to 12 cm long. The fish is transparent (hyaline) with a bluish spot on its rear, making it a notable example of animal camouflage. (Lara is a state in western Venezuela).
'that shirt is like a condocho'; this compares a shirt that is very light in color or worn thin and transparent to the clear body of the fish.
