Image of The Day caption:
Trichodesmium, shown in this micrograph, is a photosynthetic bacteria, common in warm, tropical and subtropical surface waters. Trichodesmium cells form filaments called trichomes that associate into the roughly 2mm colonies seen in these images. Turns out this intriguing microbe is also the source of an essential nutrient in the ocean.
Caption from Oceanus magazine, Vol. 47, No. 3, Pg. 6:
Some single-celled phytoplankton called Trichodesmium (seen here in distinctively shaped colonies) have a competitive advantage because they can extract an essential nutrient, phosphorus, from a source that other marine organisms can's use.
