Teach your students about the complete metamorphosis of an insect with these mealworms.

These African clawed frogs are entirely aquatic and thrive in an ordinary freshwater aquarium. They are often used in developmental studies and genetic experiments.

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

Hydra are tiny animals closely related to jellyfish. They can be carnivorous as well as photosyntheic due to their symbiotic relationship with green algae Zoochlorellae.

Hydra are tiny animals closely related to jellyfish. They are a carnivorous species that can be found in healthy freshwater rivers and streams where they attach themselves to plants and rocks.

Daphnia are a widely studied small crustacean used for a number of physiology studies including the effects of drugs on heartbeat and temperature on metabolism.

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

Planaria are a flatworm commonly used in science fair projects. They do not bite and move very slowly, making them easy for young students to observe.

Erpobdella obscura

Cockroaches are widely used in labs for physiological, behavioral, structural, and developmental studies.

Grass frogs are low maintenance and seasonally available, typically from September to July.

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.
