Marine Diatom

Cylindrotheca sp.


Less common than some of the other algae species we observed under the microscope. These were shaped like small capsules with a long needle at each end.


A marine biologist on board skimmed some plankton using really fine mesh nets and we took a drop from that sample and placed it under a microscope. The sample was skimmed in Izhut Bay just off Afognak Island in somewhat shallow water (less than 200 feet).
