Predatory. Feeds on Paramecium caudatum. Hay medium.

Characterized by cilia; nearly all possess two types of nuclei.

A collection of some of the more popular forms of coliphage. The successful culture of coliphage requires growing in the appropriate host bacterium (available separately)

A collection of some of the strains of Escherichia coli needed to grow various coliphages (available separately).

This large predatory frog will eat any other organism smaller than itself, including smaller bullfrogs; keep similar-sized frogs together to avoid cannibalism.

Two flagella; no chloroplasts. Food organism. Hay medium.

Characterized by flagella; lacks plastids.

Drosophila melanogaster, the common fruit fly, is widely used in genetic studies. They express a number of mutations such as eye, wing, and body mutations. Students can study sex-linked, recessive, and dominant mutations. Drosophila also makes an excellent live food for mantises, small reptiles, and amphibians. Drosophila demonstrates complete metamorphosis with egg, larva, pupa, and adult stages in its life cycle.

Hydra are tiny animals closely related to jellyfish. They can be carnivorous as well as photosyntheic due to their symbiotic relationship with green algae Zoochlorellae.

These fascinating frogs are uniquely adapted for climbing, with prominent adhesive pads on the ends of their digits.
