Northwest. Many drug companies and natural products chemists are now turning to the ocean as a source of similar helpful substances. Biotechnology tools are used in identifying‚ isolating‚ characterizing‚ testing‚ and synthesizing compounds discovered in marine animals and plants and then developed into drugs or other products (Fenical‚ 1993; Davidson‚ 1995; Kobayashi and Ishibashi‚ 1993). Figure 1. Proteins in the venom of venomous fish like the devil firefish (Pterois miles) may be used as therapeutic
