Amoebozoan cells characteristically exhibit pseudopodia that extend like tubes or flat lobes. These pseudopods project outward from anywhere on the cell surface and can anchor to a substrate. The protist then t
To investigate the specific mechanisms of raptorial ciliates, we collected a total of seven Haptorian ciliates, including two species from seawater and five from freshwater. Despite their large size and comparatively limited maneuverability compared to their prey, these Haptorian ciliates exhibit remarkabl...
Some protists such as the true slime molds exhibit multiple fission and simultaneously divide into many daughter cells. Others produce tiny buds that go on to divide and grow to the size of the parental protist. Sexual reproduction, involving meiosis and fertilization, is common among protists, ...
Protists, which are single-celled eukaryotes, critically influence the ecology and chemistry of marine ecosystems, but genome-based studies of these organisms have lagged behind those of other microorganisms. However, recent transcriptomic studies of cultured species, complemented by meta-omics analyses o...
in the absence of light, as a nutrient absorbing heterotroph, the euglenas are quite versatile in their ter-ritory requirements. Their range is also not limited by reproduction, which they accommodate both sexually, whenever possible, and asexually the rest of the time. Refer to the illustratio...
The toxi- cysts in their resting state exhibit a highly intricate and delicate structure, consisting of an external capsule cov- ered by a thick wall and an internal tube. It is believed that unknown toxins accumulate within the tube and are released into the prey's body through the ...
Interestingly, different phylotypes of Desulfovibrio ectosymbionts exhibit different manners of association with their respective Trichonympha host species. Whereas phylotype ZnDsv-02 (or ZnvTc-7) (AB444082 and JQ993542) attaches to a shallow groove on the surface of Trichonympha collaris cells in ...

Protists thrive in nearly every environment that includes liquid water, where they exhibit a broad range of cellular structures, locomotion modes, and lifestyles. Like bacteria, they also occupy a range of different trophic levels. Many of the predatory forms obtain nutrition using mechanisms that ...
