SMTP Research Paper Hwa Chong Institution (High School) Mentor: Mr. Chew Tyng Yong Abstract Mollusks and Crustaceans can be found vastly around the world. Arthropods have 1‚170‚000 described species‚ and account for over 80% of all known living animal species and Mollusca being the largest marine phylum‚ comprising about 23% of all the named marine organisms. With such diversity of these marine animals‚ the

Because they are grouped in the same kingdom‚ the nine animal phyla share the same fundamental characteristics- they are multicellular‚ heterotrophic eukaryotes that obtain nutrients through ingestion‚ they lack cell walls‚ they have nervous tissue and muscle tissue‚ and they reproduce sexually and have a unique embryonic life cycle. However‚ the animal phyla have a great number of differences as well. Some are visible to the naked eye‚ while others are less obvious‚ and still more cannot even be

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
