Phylum Arthropoda: Arthropods are the largest phylum in the animal kingdom, making up over two-thirds of all known animal species. They are incredibly diverse and can be found in almost every habitat on Earth, from the deepest oceans to the highest mountains. Here are some of the general characteristics of arthropods General Characters of Phylum…

Phylum Mollusca: It is the second largest phylum in animal kingdom and consists of over 150,000 marine, freshwater and terrestrial species. Mollusca, the second largest animal phylum after Arthropoda, is a diverse group of soft-bodied invertebrates . They are found in almost all aquatic environments, from freshwater to the deepest parts of the ocean, as…

Annelida: The phylum annelida was first coined by LAMARCK (1801) (Gr., annulus – little ring + eidos – form) for the higher segmented worms. There are around 16500 species included in the phylum Annelida. Appearence of metamerism represents their greatest Advancement, so they are called a Segmented worms. The unique characteristic of the phylum Annelida is metamerism….

Aschelminthes: It also referred to as Nemathelminthes, it is an invertebrates phylum which includes roundworms. Defination: They are bilaterally symmetrical, triploblastic and pseudocoelomate animals with organ system of organization. Excretion involves a giant excretory cell called Renette cell. They have tube-within-tube type of body plan. Nemathelminthes group are created by Gwgenbaur in 1859 to place…

Phylum Platyhelminthes: The phylum platyhelminthes, also known as flatworms, is a incredibly diverse group of invertebrate animals. With over 20,000 known species, but due to their small size and often cryptic lifestyles, the actual number of species is likely much higher. mostly parasites that live in other animals including man. Flatworms are found in a…

Canal System in Porifera: The canal system is a unique feature found in the phylum Porifera, commonly known as sponges. Porifera is a group of multicellular organisms that lack true tissues and organs but possess specialized cells to perform various functions. The canal system in porifera is responsible for water circulation, food capture, and waste removal….
Protozoa: Protozoans are single-celled eukaryotic organisms that are found in a variety of habitats, including water, soil, and the bodies of animals. They can be classified into four main groups based on their locomotion: flagellates, ciliates, amoebae, and sporozoans. The slides are used to study the morphology of protozoans under a microscope. The slides are…
