"live+microogranisms"

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

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.

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

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).

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.

Produces orange pigments. 

This "many-headed" organism is a plasmodial slime mold commonly found in forests on decaying deciduous trees. Available in both plasmodial and sclerotial stages.

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.

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

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