The law of intellectual property is commonly understood as providing an incentive to authors and inventors to produce works for the benefit of the public by regulating the public's use of such works in order to ensure that authors and inventors are compensated for their efforts.
Sponges, colonial animals in the phylum Porifera, are primitive invertebrates that are dominated by marine species. Typically, they are benthic, sessile filter feeders that are asymmetrical.
Classification in Phylum Nematoda. So, we've established that Ascaris is a genus of helminth. They belong to the Kingdom Animalia (just like us), and the Phylum Nematoda (from the Greek 'nematos' meaning 'thread'). Nematoda is the phylum containing all roundworm species. But, in spite of the fact that nematodes are 'roundworms', that does not mean that all worms that are round in shape are nematodes. The term nematoda actually refers, not to their body shape, but to their digestive tract, which is tube-like with tapered openings at either end.
