Phytoplankton of the month — July 2018

Odontella longicruris

Odontella longicruris are centric diatoms, approximately 15-110μ wide. Though they can occasionally be observed in their solitary form, they are often joined in straight chains. These cells have external tubes that project from central elevations at either end of the cell, and connect to neighboring cells. They have many small chloroplasts located near the cell walls, and are yellow-brown in color. Odontella longicruris are neritic.
