Morphology

Micrococcus = coccus (transparent) = micro + coccus

The meaning is directly compositional: 'micro' indicates small size and 'coccus' refers to a spherical bacterium.

Etymology

Micrococcus comes from Greek parts: micro- meaning 'small' and -coccus from a word for 'berry', so the name shows a tiny, round 'berry'. That's why Micrococcus is used for small, round bacteria often found on skin, in soil, and in water.
