Live Specimens

Classic experiment to demonstrate crossing over.

A quick and colorful demonstration of Mendel’s Law of Segregation.

Create a suitable home for fish, brine shrimp and other marine invertebrates. A 450 g bag will make three gallons of sea water (1.020-1.025 specific gravity). (Please note: This item is recommended for use with saltwater aquaria only.)

The culture supplied includes copepods in various stages of development.

Highly aggressive. Beautiful but socially challenged, male “Siamese fighting fish” will duel with each other — or even with their own reflection in a mirror — and flare their colorful fins in an impressive display of territoriality. When females are present, males will try to “impress” them. Females can coexist; males must be kept separate. Care instructions are included. Size: 1 1/2–2".

Easily compare the different types of structures in a variety of small freshwater crustaceans with this convenient freshwater culture mix.

Planorbids, mixed genera. Compare these attractive, spiral-shelled, herbivorous freshwater specimens with other snails. They will eat aquarium plants

These organisms help keep your freshwater aquarium clean by eating algae and detritus; they won’t eat any plants included in the aquarium.

Predatory. Feeds on Paramecium caudatum. Hay medium.

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

Scouring Rush. It features reedy, upright growth habit and whorls of leaves at the nodes. The shoots, which contain silica, were once used to scrub utensils and pots, giving Equisetum its common name of scouring rush. It is supplied in a plastic bag with care instructions. Quantity: 8–12 shoots.

Crayfish are a mixture of Orconectes immunis and Orconectes virilis.

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.

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.)
