The culture supplied includes copepods in various stages of development.

Predatory. Feeds on Paramecium caudatum. Hay medium.

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

The body of this ciliate is transparent, making the large cilia clearly visible.

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.)

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.

Found in seawater and marine animals. Young cultures luminescent.

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.

Marine. Unicellular. Food organism, brackish, helically coiled filaments. Marine medium.

Shipped in a form that provides the best quality specimen. Most are supplied in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars.

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

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