"Ward's Science"

Extremely small euglenoid. Usually doesn’t rotate when swimming. Scavenger. Hay medium.

Characterized by flagella; lacks plastids.

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

Characterized by a lack of rigid cellulosic walls, instead these organisms have pellicles made of protein. They store paramylon instead of starch.

One of the largest Drosophila species. Useful for preparing salivary gland chromosome squashes.

Mature Drosophila are cultured in our own labs, and are marked with the culture initiation date. Culture is shipped in our instant medium in a shatterproof vial. The Fruit Fly pupae will usually appear within ten days of the ship date. You will also receive WARD’S Drosophila Culture Guide. Note: We can supply any of our single strains in the larger quantity for 100 students. Call our Customer Service department for details.

Water mold and fish parasite. Demonstrates sporangia and oospores. Grows on wheat seed, cucumber seed, or hemp seed in water environment. Reproduces sexually and asexually. Incubation temperature 25°C.

Cell walls made of cellulose; feeds by extending hyphae into host's tissue.

Examine the morphological characteristics of typical soil nematodes with the specimens in our well-populated culture.

Hypsibius sp. The water bear is a complex animal representing the unusual phylum of Tardigrades, which contains about 400 marine, terrestrial, and freshwater species.

Create a balanced ecosystem in your aquarium with the addition of these small, freshwater algae eaters. They reproduce rapidly, laying their eggs on the glass sides of the aquarium.

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.

Long life cycle (approximately one month). Useful for comparative population studies and for preparing salivary gland chromosome squashes.

This harmless insect parasitizes the Sarcophaga (flesh fly) pupae. Females usually lay 30–50 eggs in the pupae, which provide food for the Nasonia larvae when they hatch.
