Marine Diatom

Rhizosolenia sp.


Long, thin algae with pointed tips forming chains in some cases, but many of the ones we observed under the microscrope were solitary.


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).
