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

Volvox aureus is a species of colonial green algae that forms spherical colonies of cells.

Freshwater. Filamentous; two stellate chloroplasts per cell. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

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

Freshwater, Unicellular; pennate, with bilateral symmetry. Diatom or basic medium.

Characterized by shells (tests) made of silica, in two parts.

Freshwater; elongated, biflagellate cells that form globular colonies; gelatinous sheath absent.

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 Algae & Cyanobacteria" 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.

Marine; Small Motile Cells with the Transverse Furrow Located Near the Apex.

Freshwater. Unicellular. Soil-water medium. Characterized by two flagella (one inside a groove at right angles to the other); most also have tests made of cellulose and are encrusted with silica.

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

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.

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

Marine. Filamentous; freely branched. Erdschreiber’s medium.

Characterized by green plastids and cell walls composed of cellulose.

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.
