Explanation:
Detailed explanation-1: -A pair of appendages is attached to each segment of the crayfish. The two pairs of antennae include the branched antennules, which serve as feelers sensitive to touch, taste, and balance.
Detailed explanation-2: -Note that each pair of antennae are biramous appendages. Examine the telson and uropod. How does the crayfish use these biramous appendages to escape predators? Using a probe, try to find the mouth and anus.
Detailed explanation-3: -Antennae-long thin anterior structure used to taste food, touch, and maintain balance. Antennule-short thin anterior structure used to taste food. Compound eye-objects are seen as a mosaic similar to the way insects see.
