Figure 16. — A typical starfish fighting boat of Long Island Sound. The boat is "mopping" starfish by dragging 

 special mops over the oyster beds. The starfish become entangled in the mops which, after being raised, 

 are immersed in vats of hot water to kill the pests. 



Figure 17. — A closeup of a frame with 11 mops. Numerous starfish are entangled by the small rays and pincerlike 



structures that cover their bodies.
