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 transports its cytoplasm into the pseudopod, thereby moving the entire cell. This type of...
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, ...
Dinoflagellatesare unicellular photosynthetic algae that are the principal member of the phylumPyrrophyta. They exhibit three unusual properties. First, several species are luminescent and give off light when disturbed. Second, their DNA is not packed with histones, making them separate from all other...
Briefly, to orient the reader, choanoflagellates belong to the Opisthokonta “supergroup” and are the closest extant unicellular relatives of animals,31 while MAST-3 belongs to the Stramenopila4 (Figure 2A). Both choanoflagellates and MAST-3 are known non-photosynthetic unicellular predators ...
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 ...

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 ...
