Chilomonas, a colourless (but lecuoplastidic) cryptomonad. The body shape of most cryptomonads is similar, rounded or pointed posteriorly, perhaps with a very slight twist, widest just subapically. There are two flagella which insert into a subapical pocket. The pocket is lined with explosive extrusomes (the type in cryptomonads is called ejectisome), and small extrusomes also lie under the body surface. Body often with abundant polysaccharide materials. This species can form vast numbers - usually in organically enriched low oxygen conditions. Differential interference contrast. These images were taken of protozoa among marginal debris in the slow moving freshwater stream at Audley in New South Wales Australia by Feng Wie-Song and D. J. Patterson.

Chilomonas
From the collection
Audley Bottom
| Description of Chilomonas: Colourless cryptomonads with a rostrate anterior, not phagocytic; furrow/gullet complex consisting of a vestibulum, a short furrow and long tubular gullet; both flagella with a unilateral row of tubular hairs; periplast has an inner single sheet with numerous ejectisome pores and a surface periplast component consisting primarily of fibrils. The periplastidal compartment contains leucoplasts lacking thylakoids numerous large starch grains, and several nucleomorphs located in the periplastidal space near the nucleus. Freshwater. |
