Is a plecostomus an invertebrate?
No, they are not invertebrates. While shaped differently, they are still simply fish which are all vertebrates, since they have spines (just like you and me!)
What is a jellyfish invertebrate or vertebrate?
A jellyfish is an animal in the cnidarian phylum along with anemones and other creatures with nematocysts (stinging cells). Some are tiny and some can grow very large (i.e. the lion's mane jelly). All jellyfish have nematocysts, however some jellies possess very weak nematocysts meant for tiny prey like copopods. The stinging cells in these jellies are generally not felt by humans with the exception of sensitive skin. Cnidarians do not possess brains, but some have eye spots for sensing light.
How are platyhelminthes significant to humans?
They were one of the first organisms to go through cephalizaion (the development of a brain)

How are seashell important to the environment?
Seashells are usually the homes of sea creatures, and wash up ashore when the dwelling creature dies. Without seashells, Oysters, Mussels, Clams, and Hermit Crabs would be much more vulnerable to predators.
They have many sensory organs, like olfactory papillae, eyes and termic receptors, so they can find prey or dead animal bodies.
They also suck your blood, particularly under your bathing suit and/or in your rubber boots, for a long time without you even realizing it.
