Live Specimens
Live specimens are used for a wide variety of studies including studying the physiological effects of drugs on a specimen’s heartbeat and temperature on metabolism, the locomotion of microscopic organisms, and studying plant respiration, photosynthesis, plosmolysis, and more. Algal cultures form colonies of cells that are extremely easy to visualize for better understanding of cell walls and plastids, and many live specimens reproduce rapidly for quick turnover between successive tests.

Horseshoe Crab
Limulus polyphemus. A true "living fossil", this representative of the class Meristomata is one of only five living still in existence. The crab is the most widely studied Meristomata because of their large compound eyes and their copper-based blue blood. It thrives in a marine aquarium such as WARD’S Marine Touch Tank. Culture instructions are included. Size: 1–3". Note: Shipped overnight. Additional shipping fee applies.
