The scientific classification system is divided into seven major groups, (1) kingdom, (2) phylum or division, (3) class, (4) order, (5) family, (6) genus, and (7) species.

Do snakes fart?
So, do snakes fart? Snakes can and do fart. However, due to being strict carnivores, they are less likely to fart than other mammals (as diet plays a crucial role in this behavior and the creation and buildup of gas). In a healthy snake, farts are infrequent and unlikely to be heard and smelt.
