What protein does the term coated vesicle refer to? what protein does the term coated vesicle refer to? the adaptor proteins surrounding the vesicle the ligand bound to the receptor the receptors in the membrane of the vesicle the clathrin that forces the vesicle to invaginate?

Coated vesicle refer to the clathrin that forces the vesicle to invaginate. The protein clathrin plays a major role in the formation of coated vesicles and are very important for cargo selection and for specifying the final destination. The formation of clathrin coat is vital to the mechanism of vesicle budding as well as receptor sorting. 

Used to water and cool climates, probably not thick coated or fluffy. they most likely have thin coats and have to survive to find food. sorry if this wasn't the answer you were looking for..: )
