Cattle, like other ruminant animals such as goats, deer, and giraffes, have billions of microbes inside their guts which help them digest their food. These are some of the many types of microbes that live in the rumens (stomachs) of cows. The large microbe is a type of protist. The creature that looks like a tadpole attached to the side of the protist is a fungal spore. The smaller, rod-shaped beasts lining the underside of the protist are bacteria.
