Lab # 2 - Experimental investigation of the effects of alcohol on developmental using Brine Shrimp ( Artemia ) as a model organism Background: Brine shrimp, crustaceous zooplankton belonging to the genus Artemia , are a suitable organism for studying developmental processes in animals as they develop rapidly (2-3 weeks). Ecologically, brine shrimp serve an important role as they consume algal cells in marine environments and are in turn preyed upon by small fish, thus transferring energy from the bottom to the top of the food chain. Furthermore, these crustaceans are susceptible to toxins because the bulk of the surface area is in constant contact with their watery environment. As a result, toxins can easily diffuse or enter the tissues and eggs of these shrimp via osmosis. Like many other types of zooplankton, brine shrimp have adapted to rapidly changing environmental conditions by carrying out a reproductive strategy known as diapause. Specifically, when conditions become unfavorable (e.g. poor temperatures, very high salinity) females can produced encysted eggs which protect a dormant embryo.
