is long and mostly flattened, and the first pair of legs are very large, and used for 

 seizing prey, the last joint folding over serves to answer the purpose of a claw. The 

 carapace is divided into three lobes. The best known of these crustaceans is the 

 MANTIS-SHRIMP, so called from its great resemblance to the insect from which it takes 

 its title. The carapace of the genus Squilla is small but long, and shields the mouth, 

 the antennae, and their appendages. The abdomen is very long and boldly jointed, 

 and the appendages at its extremity are made in a manner that much resembles the 

 fan-like tail of the lobster. 



All the Squillae are voracious, fierce, and active beings, and can strike as sharply 

 with their long claw-feet as can the mantis with the corresponding limbs. From all

appearance it seems as if the creatures were in the habit of hiding themselves in dark 

 crevices, and from their dens striking quickly at passing prey. ' 



This theory is much strengthened by the observations of Dr. Lukis, who kept a 

 Mantis-shrimp alive for a short time. " It sported about, and after a first approach 

 exhibited a boldness rather unexpected. When first alarmed, it sprang backwards 

 with great velocity, after which it placed itself in a menacing attitude which would 

 rather have excited the fear of exposing the hand to it. The prominent appearance 

 of the eyes, their brilliancy and attentive watching, the feeling power of the long 

 antennae, evinced quick apprehension and instinct. I brought a silver teaspoon near 

 them, which was struck out of my hand with a suddenness and force comparable to 

 an electric shock. This blow was effected by the large arms, which were closed and 

 projected in an instant with the quickness of lightning."
