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.
The Major phylums in the animal kingdom are as follows. INVERTEBRATES Phylum: Porifera Phylum: Coelenterata/ Cnidaria Phylum: Platyhelminthes Phylum: Nematehelminthes/â¦ Aschelminthese Phylum: Annelida Phylum: Arthropoda Phylum: Mollusca Phylum: Echinodermata. The phylum protozoa is now not treated as animal phylum and it is included under a separate kingdom called PROTISTA.
