Humoral Recognition Factors in the Arthropoda. The Specificity of Chelicerata Serum Lectins -- VASTA and MARCHALONIS 23 (1): ...
The authors state that arthropods have the capacity of recognizing self from non-self in various defense phenomena including hemolymph clotting, phagocytosis, encapsulation, melanization and clearance of the foreign matter which must be initiated by a first step of molecular recognition.
This review analyses the mechanisms of neurogenesis, the morphology of serotonergic interneurons, the number of motoneurons, and cellular features and development of the lateral eyes of Chelicerata.

The arthropod group Chelicerata includes animals as diverse as spiders, scorpions, mites, ticks and horseshoe crabs. In addition to these well-known living animals, it includes important extinct groups such as the eurypterids (sea "scorpions").
