These small marine crustaceans are supplied as adults, and measure approximately ¹/₄" in size at the time of shipment.

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

Study the Rotifera under your microscope to discover the variety of structures among them. Subculture them in Alfalfa or Hay medium to increase your supply. Species may vary based on availability.

Illustrate the structure, feeding habits, responses, and reproduction of a typical Anthozoan.

The nocturnal hermit crab uses “borrowed” shells to protect its relatively soft body, changing shells as it grows larger.

Aeolosoma sp. A small, freshwater Oligochaete, Aeolosoma is characterized by colorful oil droplets in its body. It’s easy to culture large quantities of this microscopic organism for use in regeneration experiments: Simply add hay and wheat grains to hay medium. Culture instructions are included. Size: 2–3 mm.

The culture supplied includes copepods in various stages of development.

Place these eggs in a brine solution for two days in order to make the shrimp (Artemia) hatch. Our special processing technique allows you to store the eggs for nearly indefinite periods of time. 7 grams.
