2nd largest phylum of animal kingdom

Hint: Jointed appendages allow more movement, protecting them from predators, leading to their success. Complete answer: Arthropoda is the largest Phylum in the Animal Kingdom. Over two-thirds of all named species on earth are Arthropods. They consist of over 90,000 species. Additional Information: They have an organ-system level of organization. Bilaterally symmetrical, triploblastic, segmented, coelomate, diaceous, oviparous are a few characteristics of this phylum. They have a chitinous exoskeleton, which is another reason which led to their success. The body can be distinctly divided into head, thorax, and abdomen. Respiratory organs are gills, book gills, book lungs, or tracheal systems. They have an open circulatory system and excretion takes place through malpighian tubules. They undergo internal fertilization. Sensory organs, like antenna, eyes, and balance organs are present. Arthropods are traditionally divided into 5 subphyla: Trilobitomorpha (Trilobites), Chelicerata, Crustacea, Myriapoda, and Hexapoda; which are further divided into classes. Arthropods are important in maintaining the ecological balance in nature and provide natural services to humans and act as the pollinators, natural enemies, scavengers, leaf-litter sweepers, garbage collectors, soil conditioners and natural fertilizer producers in nature. Notes: -Limulus (King Crab) is known as the living fossil. -Mollusca is the second largest Phylum while Chordata is the third-largest Phylum. -The term ‘...

Hint: Second largest Phylum is both terrestrial and aquatic Complete answer: Mollusca is the second largest Phylum in the Animal Kingdom. Molluscs are both terrestrial and aquatic (marine or freshwater). They have an organ-system level of organisation. They are bilaterally symmetrical, triploblastic and coelomate animals. Their body is covered by a shell. They have a distinct head, muscular foot and visceral hump. Mantle cavity is the space between the visceral hump and soft skin, in which feather-like gills are present. They have distinct respiratory and digestive functions. Anterior head has sensory organs, Radula is the feeding organ. They are diacious, oviparous and undergo indirect development. Additional Information: Usually molluscs are hermaphrodites, that is they are diacious, produce both male and female gametes and do not need a partner for sexual reproduction. Molluscs are further divided into six classes; Monoplacophora, Amphineura, Scaphopoda, Gastropoda, Bivalvia and Cephalopoda; each of them have a distinct character. Molluscs have several economic importance - they are used as food, for decoration, in jewelry, and in scientific studies. They are even used as roadbed material and in vitamin supplements. Notes: - The largest phylum in the animal kingdom is Arthropods. - Examples of Molluscs include - Pila, Pinctada, Loliga, Octopus, Dentalium etc. - Chordata is the third largest phylum in Animal Kingdom.

Animal Kingdom: • Kingdom Animalia refers to all animals. • The animal kingdom is the most populous of the five kingdoms. • Animals are eukaryotes with many cells. Arthropods: • Arthropoda is the largest phylum in the animal kingdom. • The word ‘arthropod’ means ‘jointed legs’ and hence they have jointed legs. • Examples: Lobsters, crabs, spiders, mites, insects, centipedes, and millipedes.

arthropod, (phylum Arthropoda), any member of the phylum Arthropoda, the largest phylum in the The distinguishing feature of arthropods is the presence of a jointed skeletal covering composed of arthropod (“jointed feet”) is derived. About one million arthropod species have been described, of which most are insects. This number, however, may be only a fraction of the total. Based on the number of undescribed species collected from the treetops of tropical forests, zoologists have estimated the total number of insect species alone to be as high as 5.5 million. The more than 48,000 described species of mites may also represent only a fraction of the existing number. The phylum Arthropoda is commonly divided into four subphyla of
