How is this worm adapted to a parasitic lifestyle?<\/td>\n1.\u00a0\u00a0\u00a0\u00a0 Scolex with hooks for attaching to intestines of host<\/p>\n

2.\u00a0\u00a0\u00a0 No mouth or digestive system – long flat body absorbs nutrients directly from host<\/p>\n

3.\u00a0\u00a0\u00a0 Sensory receptors reduced or absent<\/p>\n

4.\u00a0\u00a0\u00a0 Tegument (modified epidermis) protects against hosts digestive enzymes and immune system<\/p>\n

5.\u00a0\u00a0\u00a0 Cuticle secreted by the epidermis also protects the worm<\/p>\n

6.\u00a0\u00a0\u00a0 Hermaphroditic with well developed reproductive system capable of mating with each other and producing hundreds of thousands of eggs (no digestive system makes more room for eggs)<\/p>\n

7.\u00a0\u00a0\u00a0 Proglottids capable of mating with each other, drop off when eggs ripe to infect intermediary host<\/p>\n

8.\u00a0\u00a0\u00a0 Embryos form a bladder or cyst in intermediary host and wait to be eaten by primary host<\/td>\n

1.\u00a0\u00a0\u00a0\u00a0 Oral sucker for attaching to host<\/p>\n

2.\u00a0\u00a0\u00a0 tegument ot protect against hosts’s digestive juices and immune system<\/p>\n

3.\u00a0\u00a0\u00a0 Larvae able to burrow through host tissues and use the circulatory system to travel throughout the body<\/td>\n

1.\u00a0\u00a0\u00a0\u00a0 Female lays 200,000 eggs per day which pass out with feces<\/p>\n

2.\u00a0\u00a0\u00a0 When new host eats contaminated food new infection occurs<\/p>\n

3.\u00a0\u00a0\u00a0 Larvae able to burrow through host tissues and use the circulatory system to travel throughout the body<\/td>\n

1.\u00a0\u00a0\u00a0\u00a0 Larvae form cysts in muscle tissue<\/p>\n

2.\u00a0\u00a0\u00a0 When muscle eaten by predator, larvae are released into stomach to begin life cycle<\/p>\n
