Discovered in a seawater filtration system in Curaçao, this protozoan species can spontaneously develop into supergiants more than twice its normal size, with a broader body and larger mouth. In its normal state, Euplotes gigatrox filter-feeds on bacteria, but upon transformation, it becomes a raptorial predator, hunting and devouring members of its own species. The transformation also alters its movement, changing from graceful swimming to circular hunting paths and clumsy tumbling, indicating a shift in its ecological niche. This discovery challenges previous understandings of developmental biology, demonstrating complex behaviours and distinct developmental stages, including widespread gene activity differences, in a single-celled organism, a phenomenon largely associated with multicellular animals until now.
