Invertebrate such as a crab, ant or spider (9)

Ross

I believe the answer is:

arthropod

(Other definitions for arthropod that I've seen before include "spider, for example" , "Creature such as insect or crustacean" , "worker, perhaps" , "Such as a crustacean or spider" , "Invertebrate" .)

I've seen this clue in The Times.
