deepwater crustaceans requires less energy to 

 maintain and thus represents an adaptation for 

 energetic efficiency in a habitat where food is 

 scarce. In addition, long legs may allow a crab to 

 move more rapidly or more economically by tak- 

 ing fewer, larger steps to travel a given distance.
