The paper reports the discovery of exotic catenulid flatworm species in a temperate botanic garden greenhouse and provides molecular evidence for their phylogenetic placement.

This study shows that excessive feeding in flatworms leads to the formation of colony-like body plans through changes in growth rates, without requiring new developmental programs or adaptive benefits.

The paper surveys catenulid diversity in Central and Western Europe, focusing on Poland, using molecular markers to infer phylogeny and identify taxonomic challenges.

The paper describes a spontaneous developmental error in flatworms leading to double-headed worms with reversed body axis polarity, which can regenerate normally.
