"Euglena+live"

Ward's® Live Escherichia coli, Lactose Negative Culture

This large predatory frog will eat any other organism smaller than itself, including smaller bullfrogs; keep similar-sized frogs together to avoid cannibalism.

These fascinating frogs are uniquely adapted for climbing, with prominent adhesive pads on the ends of their digits.

Paramecium bursaria is a ciliate that contains mutualistic algae called Zoochlorella. The algae lives in the cytoplasma of the Paramecium and provides it with food. Paramecium bursaria grows in Dilute Alfalfa Medium (Hay Medium) or Soil Water Medium. Requires light for growth.

Commonly known as the Vinegar Eel, these free-living nematodes require very little care, feeding in vinegar and feeding on fungi contained in it.

Four to six adults of each sex (including virgin females) have been carefully selected for the parent generation. Larvae will be visible within a week of receipt. Please order 7-10 days in advance.

We fully guarantee the purity and viability of our Drosophila melanogaster cultures. A large, vigorous culture is shipped in a shatterproof plastic vial. To ship Drosophila cultures with living larvae we require 10 days' notice prior to use date. During very cold weather, adult flies may die but eggs and larvae usually survive. Allow cultures to come to room temperature before checking under low magnification for eggs and live larvae. Complete instructions are always included.

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.

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

Ideal for use as a model system, this free-living nematode has biological processes similar to those of other animals. The transparent animal normally inhabits soil.

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

Produces orange pigments. 

Paramecium aurelia is the smallest species of Paramecium we offer. Paramecium aurelia is characterized by cilia, which it uses for locomotion and feeing. Contains a macronucleus and two micronuclei. Grows in Dilute Alfalfa Medium (Hay Medium).

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

Found on dental plaque, implicated in cavities. No Lancefield group shown, gamma hemolysis. 

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

Bullfrog tadpoles are great for demonstrating metamorphosis in the classroom.
