Tintinnidae

From the Bay of Villefranche in December 2013, lugol's-fixed specimen, Z-stack of images made using a 60x objective and DIC optics.

Drawing from Claparde & Lachmann 1858 (Plate 8, figure 5) of the species now known as Steenstrupiella steenstrupii as "Tintinnus steenstrupii". The scale bar reflects the text description (pg 200) as about 0.2 mm in overall length. The species (and now genus) was presumably named after the Danish biologist Japetus Steenstrup (1813-1897).

This form does not have a name as far as I know

In a sample from the Tara expedition (Station 68) there were 30 large cells for about 1000 'normal-size' cells.

Genetic material is shared between two individuals by the formation of a cytoplasmic bridge

A pair of tintinnid ciliates caught in the act of exchanging genetic material.
