Hydra are tiny animals closely related to jellyfish. They are a carnivorous species that can be found in healthy freshwater rivers and streams where they attach themselves to plants and rocks.

With stiff 'arms' radiating in all directions, these microscopic organisms look like sea urchins

Mixed genera. Also known as scuds, amphipods are freshwater crustaceans.

Usually found in freshwater and mosses, this organism has a hard umbrella shaped shell or "test", out of which finger-like pseudopodia project.

One culture containing brown, black and white planaria is useful for comparative study.

Philodina sp. Easy to culture and easy to examine under a microscope because of the lack of a lorica (shell), these typical rotifers are perfect for general study. Culture instructions are included.

You will receive a sample of both green and brown hydra mixed together, allowing you to observe the differences between the two organisms.

These bottom-dwelling bivalved crustaceans are found in nearly every aquatic habitat.

This is the most widely studied Turbellarian, a free-living flatworm commonly used in science fair projects.

Very large ciliate. Feeds on colpidium. Hay medium.
Characterized by cilia; nearly all possess two types of nuclei.

Paramecium caudatum is a common protist that inhabits a variety of aquatic ecosystems.

This organism is easily recognized by its trumpet-shape, and can commonly be found in freshwater ponds and streams. It reproduces by budding.

Pink to bright rose color.
Characterized by cilia; nearly all possess two types of nuclei.

A very large Protozoa that graphically demonstrates the basic animal cell.

Live Cultures are supplied with media in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars. Fast delivery is available directly from our laboratory. Please specify a delivery date.

Each culture shipment is prepared in our laboratories and includes the "Working with Protozoans" manual which contains detailed instructions for subculturing and use.

Canadian Customers:
CFIA and PHAC regulations require customers to submit a completed inspection checklist and signed statement of facilities compliance before receiving certain cultures. A customer service representative will contact you if documentation is required.

Our cultures undergo strict biochemical screening and are unconditionally guaranteed for species and purity. Each culture is labeled with scientific name, media on which it was cultivated and optimum growth temperature. Although our cultures are considered non-pathogenic, standard bacteriological laboratory procedures should be used at all times. Cultures are available either live for immediate use or freeze-dried for convenient storage until needed. (Please note: We are not responsible for any infection resulting from the use of our cultures.)

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.
