TF Adult Acanthocephala are dioecious and males and females each bear two gonads TF Gubernacula act to guide spicules to open the female gonopore during coitis TF The apical complex consists of a conoid, rhoptries and micronemes. T F Dirofilaria immitis is a filarid worm that causes heartworm infection in dogs and cats. TF Acanthocephala exclusively utilize 2 intermediate hosts in their life cycle. TF Trichinella parasites can be characterized by the structure of its buccal capsule which is called the stichosome. TF Microfilaria are immature L3 larvae released by adults to be picked up by arthropod vectors for transmission TF Onchocerca volvulus is the causative agent for river blindness where an adult worm penetrates the eye and wanders through the aquaeus and vitreous humor distorting the individuals visualacuit.
