Coccus

∞ generated and posted on 2016.01.14 ∞

Bacteria that are approximately spherical in shape.

Cocci (plural) can be found in arrangements such as diplococci, streptococci, sphaphylococci, tetrads, and sarcina. Note that very short rods can superficially resemble cocci but nevertheless are note strictly considered to be cocci: See coccobacillus.

Cocci interact with the world in the same way in all directions. As such, this makes directional movement difficult. Consistently, a feature lacking in cocci is flagella.
