Clathrulina, one of the desmothoracid protists. Stalk and lorica. Bright field.

Clathrulina (cla-through-line-a), showing head region and included amoeboid cell. This image shows the stiffened pseudopodia which led the desmothoracids to be regarded as a type of heliozoon. Differential interference contrast.

Clathrulina, desmothoracid flagellate, traditionally regarded as a kind of heliozoon. The trophic cell lives as an amoeba within a stalked lorica, and pseudopodia extend from the lorica. This reproduces to form a flagellated cell which leaves the lorica and establishes itself elsewhere. Phase contrast.

Clathrulina, one of the desmothoracid protists. Traditionally classified as the heliozoa because of the star-shaped appearance of the cell, but the heliozoa have always been a rag-bag of unrelated organisms. Desmothoracids may adopt one of several forms. A ‘mature’ trophont (feeding form) is an amoeboid organism with stiffened arms. It lives in an spherical (ish) organic lorica which has large openings. The chamber is borned on a hollow stalk, and several stalked loricae may be joined end to end or in a branching arrangement. The stiffened pseudopodia extend out of the openings to capture food. Division leads to the formation of flagellated cells one or all progeny vacate the lorica, swim around and then settle as an amoeba. The amoeba secrete a stalk and mucus, and the mucus is shaped and accretes to form a lorica. The lorica strengthens and thickens with age. This image is of a cell that has recently begun the process of creating a lorica. Differential interference contrast.
