Phaeocystis antarctica

This Haptophyte species is strictly oceanic and is only found in the Antarctic. It survives best in 2-4 degrees Celsius and in high salinity. The colonies are incased inside a mucilaginous envelope creating a bubble effect as in the photo on the left. The photo on the right is still encased, but the cells have grown to the edges and obscures the wall. The sample above is from a culture grown in SERC's Photobiology and Solar Radiation Lab. The Photobiology studies the effects Ultra-violet B and phytoplankton photosynthesis in the Antarctic. Click here for more information.
