Chilaria
From Wikipedia, the free encyclopedia
Chilaria (singular chilarium) is a pair of reduced appendages located just posterior and medial to the last walking legs in Xiphosura (horseshoe crabs). The words originates from Greek and means "small lips".
Their function is unknown, and there is some controversy about their evolutionary significance (some specialists believe that they may reflect an additional opisthosomal segment).
