Also Known As:

This is a raphid pennate diatom, 15-17 µm in length, 3-5 µm in width. The taxon is photosynthetic, with 2-6 chloroplasts depending on valve length. Diagnostic to the genus, this taxon only has raphe slits on one valve; the rapheless valve instead has a central sternum across the apical axis.

These diatoms appear to be endemic to sea turtles and manatees and could have applications to research on diatom diversification as well as bioindication on sea turtle and manatee biogeography and health.

Why can't I purchase this strain?

The availability of UTEX algal strains changes on occasion; cultures may be temporarily deactivated in the online catalog if they are not considered to be healthy or if they are being cleaned for contaminants. Depending on the degree of attention needed, it may take 4-12 weeks before a culture is recovered and added back to the list of active strains.

We encourage you to explore and learn about the many diverse strains in the Collection. If a particular strain is unavailable for purchase, enter your e-mail address above to be placed on a notification list, and UTEX will contact you when it is placed back into active circulation.
