Sergeeva, Nelli & Dovgal, Igor, 2014, First finding of epibiont peritrich and suctorian ciliates (Ciliophora) on oligochaetes and harpacticoid copepods from the deep-water hypoxic / anoxic conditions of the Black Sea, Ecologica Montenegrina 1 (1), pp. 49-54 : 52-53

Corynophrya lyngbyi (Ehrenberg, 1834)

( Fig. 4 )

Diagnosis. Aloricate suctorian ciliate with cell body irregular-shaped oval, slightly wider anteriorly. The retractile capitate tentacles located on the anterior body surface. The length of stalk is at least four times the body length. Macronucleus is horseshoe-shaped.

It should be mentioned that length of the stalk in observed individual of the species was not exceeding the height of the body.

Marine species, attached to various substrates such as hydroids and algae. This is the first record of the species in the Black Sea.

Measurements (in µm): body height 42 (40-80 after Curds 1987), width 44; stalk length 32 (120-400 after Curds 1987); length of the contracted tentacles 7-13.

The distribution of ciliates on the body surface of both oligochaete and harpacticoid hosts had no a specific distributional pattern at certain areas, and were distributed from the head to the end of the body. In the case of the harpacticoid hosts the suctorian ciliates were attached on the antennae, furcas, carapaces and egg sacs.
