Thalassiosira (tha-lassy-owe-sire-a) eccentrica is one of the hundred or so species in the diverse and common genus of centric diatoms frequently found in marine waters. Some species can be very large. Species are distinguished primarily by the pattern of sculpting in the valve elements of the shell or frustule. The cell to the left is seen in girdle view, the one to the right in valve view. The margins of the valves give rise to a small number of fine chitinous filaments which are believed to function in flotation. These filaments are evident in arising from the cell to the right. With many small golden plastids. Phase contrast microscopy. data on this strain.

Thalassiosira (tha-lassy-owe-sire-a) eccentrica is one of the hundred or so species in the diverse and common genus of centric diatoms often found in marine waters. Some species can be very large. Species are distinguished primarily by the pattern of sculpting in the valve elements of the shell or frustule. This species has a seven-fold symmetry in the strutting which lies immediately below the surface of the valve, and can be seen in this isolated valve. Differential interference microscopy. data on this strain.

Species are distinguished primarily by the pattern of sculpting in the valve elements of the shell or frustule, and this shows the surface of an isolated valve. Differential interference microscopy. data on this strain.

Thalassiosira (tha-lassy-owe-sire-a) eccentrica is one of the hundred or so species in the diverse and common genus of centric diatoms frequently found in marine waters. Some species can be very large. Species are distinguished primarily by the pattern of sculpting in the valve elements of the shell or frustule. The margins of the valve have a number of stout processes and these give rise to the chitinous threads. This is a girdle view and shows the processes as well as the plastids. data on this strain.

Species are distinguished primarily by the pattern of sculpting in the valve elements of the shell or frustule. This is the valve view showing the sculpting of the valve and the underlying plastids. Differential interference microscopy. data on this strain.

Some species can be very large. Species are distinguished primarily by the pattern of sculpting in the valve elements of the shell or frustule. This is the girdle view showing the plastids located near the valves and a central nucleus. Differential interference microscopy. data on this strain.
