Synedra

Synedra is a long skinny, needle-like diatom.

Genus: Synedra

Diatom

Synedra is a long skinny, needle-like diatom. Several cells can join to form a colony with cells radiating out in all directions (as in the pictures) or it can be single cells. A Synedra colony can get confused with Asterionella, but Asterionella is in one plane whereas Synedra is in all directions.
