Only one study has examined the importance of sperm length for sperm competition success in a species with more typical flagellate sperm.
These data indicate that the jakobids are most similar to an interesting collection of other flagellate groups that possess suspension feeding grooves.
This type of screen is biased toward reversion events that result in a high percentage of flagellate cells.
Figure 1.6 shows a flagellate protozoan and a flagellar pocket in detail (open arrow).
On the basis of this information it has been proposed that the earliest metazoans were probably wormlike organisms, similar to the larvae of modern cnidarians and developed from flagellate protists.
In addition to the protozoan in Figure 1.6, several other types were found, including amoebae, other flagellates and ciliates.
Constantly flagellating him, or yourself, is not going to create the relationship of love you want to be in.
Blood flows freely as Jesus Christ is flagellated by Roman soldiers and the scenes of the crucifixion of Jesus Christ are, indeed, not pleasant viewing.
Some of the critters, including members of two major protist groups - the whip-tailed flagellates and hairy ciliates - harbor bacteria internally.
The green flagellates known as ‘the volvocine algae’ constitute a happy exception to this general rule.
