What type of fertilization do arthropods typically have?

Step-by-step solution

They have organ-system level of organisation. They are bilaterally symmetrical, triploblastic, segmented and coelomate animals. The body consists of head, thorax and abdomen. They have jointed appendages (arthros-joint,poda-appendages). Respiratory organs are gills, book gills, book lungs or tracheal system. Circulatory system is of open type. Sensory organs like antennae, eyes (compound and simple), statocysts or balancing organs are present. Excretion takes place through malpighian tubules. They are mostly dioeci
