Yes, that is true.
Yes
Yes. However, this is not a true coelom. Roundworms are pseudocoelomates -- their mesoderm lines the endoderm and ectoderm, but there is no connection between the two. Therefore, it does not satisfy the definition of a coelom. However, since there is a body cavity still, this animal is said to be a pseudocoelomate.
Trinchinosis is usually caused by eating flukes in raw fish
Annelids are bilaterally symmetric and triploblastic protostomes with a coelom, closed circulatory system and true segmentation. Their segmented bodies and coelom have given them evolutionary advantages over other worms.
The scientific name for a true worm is "Annelida". Annelids are a diverse group of segmented worms that includes earthworms, marine worms, and leeches.
No, in fact leeches are annelida or segmented worms, like the earthworm. Sponges are something completely different, really just colonies of single cells that can also live apart. Leeches are full animals with organs and stuff.

In place of the tough outer covering that protects the other creatures to which they are related, segmented worms have developed fluid-filled bodies for rigidity of form. Although given only scant consideration by most people, including aquarists, this phylum contains creatures of immense importance to hobbyists and nonhobbyists alike
Segmented worms, known as annelids, have bodies made up of repeated segments. They include common earthworms and marine bristle worms. Annelids have a true coelom and exhibit a high level of cephalization, with a well-developed nervous system and sensory organs. They play important roles in ecosystems by improving soil health and serving as food sources for other organisms.

Black worms, often referred to as mud or aquatic worms (Lumbriculus variegatus), are not parasitic. They are benthic organisms typically found in freshwater environments, where they play a role in the ecosystem as detritivores, feeding on decomposing organic matter. While they can host certain microorganisms, they do not rely on a host for survival or reproduction, distinguishing them from true parasites.
no it's not true worms don't have mouths
Trout do not have segmented bodies in the way that some invertebrates, like worms or insects, do. Instead, trout and other fish have a streamlined body structure that is divided into distinct regions, including the head, trunk, and tail. Their bodies are covered in scales, and they possess fins that aid in locomotion, but these features do not constitute true segmentation. Thus, while their anatomy has organized sections, it is not segmented in the traditional sense.
