PLEASE ANSWER THESE QUESTIONS AND BRIEFLY EXPLAIN WHY!!
1. skeletal muscle.
Adult worms reside in intestine of pig where they breed and produce larvae that invades skeleton muscles of host.
2.lack a true coelom.
These animals do not have true coelom and consists of a haemocoel, but the only place where a true coelom can be found is around the gonad.
3. Located near rectum.
They have three tubular glands similar to Malphighian tubules of Arthropods locates near rectum.
4. Stylets.
The tubular mouth is armed with stylets, which are used to pierce the plant cells, algae, or small invertebrates on which the tardigrades feed.
