This Single-Celled Organism Turns into a Cannibalistic Predator, Swallowing Its Own Relatives Whole
A newly discovered single-celled organism from Curaçao, named Euplotes gigatrox, exhibits cannibalistic behavior by transforming into larger predators that consume their own relatives. Researchers found that these 'supergiants' represent a distinct life stage, shifting their diet from bacteria to hunting smaller members of their population. This discovery challenges traditional views of single-celled organisms and provides insights into cellular development and behavior under changing environmental conditions.
- ▪Euplotes gigatrox can transform into oversized 'supergiants' that hunt and consume their own relatives.
- ▪The transformation occurs when food becomes scarce, allowing a small percentage of the population to exploit a different food source.
- ▪Supergiants exhibit significant changes in cellular activity, indicating they represent a distinct life stage rather than just larger versions of normal cells.

Opening excerpt (first ~120 words) tap to expand
Single-celled organisms aren't usually thought of as dramatic. With no organs, nervous systems, or complex bodies, they often seem like the simplest forms of life imaginable. But a newly discovered microbe from the Caribbean island of Curaçao is challenging that assumption in spectacular fashion. Researchers from the Rensselaer Polytechnic Institute (RPI) have identified a species that can transform into a giant cannibalistic version of itself, abandoning its usual diet to stalk, capture, and devour its own relatives.The discovery, published in the Proceedings of the National Academy of Sciences (PNAS), suggests that even a single cell can undergo surprisingly complex developmental changes, features scientists have traditionally associated with animals."This is a single cell doing…
