Product Details

Observe predator–prey behaviors with live organisms! Watching organisms attack prey is sure to create tremendous student interest and hone observational skills. The soft-bodied oligochaete worm Lumbriculus variegatus is a frequent prey of vertebrate and invertebrate predators. Lumbriculus is fed to hydra and planaria, and students witness the detection mechanism, the attack, the devouring and the escape behaviors. Lumbriculus can also be fed to crayfish, leeches, fish and other aquatic predators.

Complete for 30 students working in pairs. Worms, planaria and hydra are required and available separately.
