Rhabditis sp. Easily grown on potato medium and easy to maintain, Rhabditis can be used as food for predatory fungi such as Arthrobotrys. You will receive enough materials for 35 students and culture instructions.

Ideal for use as a model system, this free-living nematode has biological processes similar to those of other animals. The transparent animal normally inhabits soil.

Green shale which contains approximately 85% Illite. Impurities may include other clay minerals, such as micas and feldspars.

Marine, Macroalga, Multicellular; membranous thallus. Collected. Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Filamentous. Basic culture solution.

Characterized by reddish plastids (rhodoplasts).

This large bovine heart is ideal for demonstrations. Weight: approximately 5 lbs.

All specimens listed below are included in individual jars with each set. Guide included with each set.

Formaldehyde-free pig hearts, available in vacuum packs.

An excellent specimen used to demonstrate the insect body structure.

Wheat rust. All spore stages: pycnia, aecia, telia, and uredia.

Serial cross sections.
