Collective defense by spiny lobster (Panulirus argus) against triggerfish (Balistes capriscus): effects of number of attackers and defenders.

The article focuses on the findings of a study concerning the defense of Caribbean spiny lobster or Panulirus argus against triggerfish or Balistes capriscus. Researchers of the study theorized that larger fish numbers would be more effective in intimidating the prey regardless of lobster group size. The study reveals that lobsters assembled into outward facing remain coherent in their spacing and defend themselves by parrying with their spinous antennae when threatened. The researchers found that average mortality declined with lobster group size.
