NEWLY DISCOVERED DEEP-SEA MARINE CARNIVOROUS SPONGE Phylum Porifera is considered as a simplest form of animal consisting of sponges. Many families under this phylum have distinctive characteristics specifically feeding processes that help them become successful in terms of adaptation and survival despite of being simple and some are smaller compared to other marine organisms. A new species of carnivorous sponge (Phylum Porifera) have been discovered in the coast of Namibia particularly in the

Animal Phyla Lab Adapted from “Phylum Lab” produced by the National Aquarium in Baltimore The diversity of animal life on Earth is astounding. Each animal has a unique body plan which allows it to survive and adapt to its given surroundings. With such an abundance of species‚ classifying animals into different categories is necessary. At first the diversity of animals can be overwhelming‚ but after further research and observation‚ many likenesses appear. These similarities become the basis for

BIOLOGICAL NOTE ON LEUCONOID SPONGES WRITTEN BY MBA UCHECHUKWU EMEA EBI MOUAU/13/27603 FEBRUARY‚ 2015. A Short Biological Note on Leuconoid Sponges Sponges come under the phylum porifera and they are believed to be amongst the most unusual animals. Because of their lifestyle and appearance‚ they were originally thought to be plants especially since some are green due to commensal algae. Sponges are as well the most primitive metazoans

CHAPTER 4 ANIMAL KINGDOM Animal Kingdom is characterized by multicellular‚ eukaryotic organisms. The cells lack cell walls. They ingest and digest food (holozoic)‚ hence they are heterotrophic. Higher forms show elaborate sensory and neuromotor systems. Majority of them are motile. Reproduction is mostly sexual and embryological development is present in them. About 1.2 million species of animals are described till now. The classification helps to assign a systematic position to newly described

Animal Kingdom The animal kingdom is a taxonomic kingdom composed of multicellular‚ eukaryotic organisms. Mostly‚ their body structures become fixed as they develop‚ yet still some organisms in this kingdom have the ability to undergo metamorphosis. The majority of these organisms are motile‚ which means they can move on their own and with spontaneity. All animals are heterotrophic‚ which implies that they depend on other organisms for food. Animals live in places that provide their necessities
