How many rows of eyes do wolf spiders possess, and what feature characterizes the central pair?
Answer
Eight eyes in three distinct rows, with two very large, prominent central eyes.
The visual apparatus of the wolf spider is highly specialized and serves as a key identification feature, consisting of eight eyes arranged across three separate rows. The bottom row contains four smaller eyes set closely together. Above these, centrally positioned and significantly larger than the others, are two prominent eyes that grant superior vision and excellent light-gathering capabilities essential for tracking moving targets. The final two medium-sized eyes are set back above this large pair. This specific configuration, particularly the size and positioning of the anterior median eyes, is crucial for their success as pursuit predators.
