pairs of antennae‚ the first of which is biramous‚ the second uniramous‚ make up the first two pairs of appendages. Both pairs of antennae are used for sensory purposes. Behind the antennae there are a pair of mandibles‚ a pair of maxillulae‚ and a pair of maxillae. (Haug et al. 2012) The mandibles are used for crushing food‚ and both the maxillulae and the maxillae are used to taste and manipulate food. The head also bears a pair of very complex compound eyes‚ each of which may contain up to ten thousand
