rudimentary eyes and ears are covered with a delicate 
hood to shield them from harm. Powerful muscles con- 
tract and expand 
the rim of the um- 
brella, guided by 
nerves lately dis-

animals, while the 
mouth of the hang-

get loose from the 
strong grasp, the 
poison works and 
it soon floats dead 
on the water.
