Sessility (zoology)

In zoology, sessility is a characteristic of some aquatic animals, such that they are not able to move about. Sessile animals are usually permanently attached to a solid substrate of some kind, such as a part of a plant, a dead tree trunk, or a rock. For example, barnacles attach themselves to the hull of a ship, but corals lay down their own substrate.

Sessile animals typically have a motile phase in their development. Sponges have a motile larval stage, which becomes sessile at maturity. In contrast, many jellyfish develop as sessile polyps early in their life cycle. In the case of the cochineal, it is in the nymph stage (also called the crawler stage) that the cochineal disperses. The juveniles move to a feeding spot and produce long wax filaments. Later they move to the edge of the cactus pad where the wind catches the wax filaments and carries the cochineals to a new host.

Many sessile animals, including sponges, corals and hydra, are capable of asexual reproduction in situ by the process of budding.

Zoology

Zoology (/zoʊˈɒlədʒi/, zoh-OL-luh-jee) or animal biology is the branch of biology that relates to the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek ζῷον, zōon, i.e. "animal" and λόγος, logos, i.e. "knowledge, study".

History

Ancient history to Darwin

The history of zoology traces the study of the animal kingdom from ancient to modern times. Although the concept of zoology as a single coherent field arose much later, the zoological sciences emerged from natural history reaching back to the works of Aristotle and Galen in the ancient Greco-Roman world. This ancient work was further developed in the Middle Ages by Muslim physicians and scholars such as Albertus Magnus. During the Renaissance and early modern period, zoological thought was revolutionized in Europe by a renewed interest in empiricism and the discovery of many novel organisms. Prominent in this movement were Vesalius and William Harvey, who used experimentation and careful observation in physiology, and naturalists such as Carl Linnaeus and Buffon who began to classify the diversity of life and the fossil record, as well as the development and behavior of organisms. Microscopy revealed the previously unknown world of microorganisms, laying the groundwork for cell theory. The growing importance of natural theology, partly a response to the rise of mechanical philosophy, encouraged the growth of natural history (although it entrenched the argument from design).

General Characteristics of Porifera Poriferans are commonly called sponges. These are multicellular organisms which are sessile/sedentary in nature. Most of them are marine while a few are fresh water forms. Body is cylindrical, asymmetrical or has radial symmetry. Body wall is diploblastic which consists of an outer layer called pinacoderm and an inner layer called choanoderm. The middle layer is called mesenchyme which has various kinds of wandering amoebocytes. Body wall contains numerous pores called ostia through which water enters in the body through a canal system into the central body cavity, called spongocoel. The canal syytem mainky comprise of incurrent and excurrent canals which are lined with pinacocytes; and radial canals which are lined with choanocytes (flagellated cells). Body also contains one or more openings called oscula (-um/singular) through which water passes out from the body. Sponges feed on minute organisms and small organic particles which enter the body through water current and are ingested by the choanocytes. Respiration takes place by diffusion of oxygen from water the flowing into the body. Sponges have an exoskeleton which is made up of either spongin fibers or calcareous/siliceous spicules or a combination of both. Excretory product, mainly ammonia, is released from the body through outgoing water current. Reproduction may be asexual or sexual. Asexual reproduction takes place by external or internal budding (formation of gemmules) or by disintegration of body into reduction bodies. Sexual reproduction involves internal fertilization. Male gametes enter the sponge body through water current and fertilize with ovum with the help of choanocytes. The larval stage of calcaroeus sponges is amphibalstula while that of demospongiae is rhagon larva.

Urochordates and Cephalochordates are protochordates or lower chordates.Tunicates are included in subphyllum urochordata,ascidian comprises the largest class of tunicates,lancelets or amphioxus are included in subphyllum Cephalochordata.some members of the urochordata are planktonic as adults e.g apendicularians and thaliaceans and ascidians are sessile as adults.sessile urochordates attach their saclike bodies to rocks and other solid substrates.the unattached end of urochordates contains two siphons that permit seawater to circulate through the body.one siphon is oral which is the inlet for water,and also serves as the mouth opening. The second siphon,the atrial siphon is the opening for excurrent water.The Cephalochordates are small tadpole like animals they are elongate laterally flattened .contraction and relaxation of their muscle cells help in burrowing and swimming respectively.

PROTOZOA - GENERAL CHARACTERS AND CLASSIFICATION: The name protozoa -- (protos means first and zoan means animal) coined by Goldfuss (1818).It was Von Siebold (1845) who, recognized the unicellular nature of protozoa.Anton von Leuwenhoek first observed protozoan under microscope. First protozoan observed was Vorticella convellaria. Protozoa are generally microscopic -- they are found in fresh water,saltwater,dampsoil, while some are parasitic,symbiotic,commensals. They are called acellualr or non cellular because their bodies are not differentiated into cells,or unicellular and one cell performs all functions. Protozoa forms a heterogeneous group,the members display an extreme diversity of structure,different types of symmetryand adaptations to various environments. Many protozoa are complicated in structure. Some protozoa form colonies.Protozoa might be defined as an organism which is made up of mass of protoplasm not divided into cells and which carries on all vital activities of life such as locomotion,feeding,digestion,respiration,excretion, reproduction etc. Although it is not divided into cells,it has specialization and division of labour with in its cytoplasmic mass.It is erroneous to think of protozoans as simple animals,for many have complicated structures and are physiologically complex. Body is naked or covered by a pellicle or a shell made of silica or calciumcarbonate.Giarelia shows bilateral symmetry. Helizoans and radiolarians showspherical symmetry. Sessile forms like choanoflagellates are radially symmetrical. The vital activities of the body are performed by different organelles of thecell,hence division of labour is at sub-cellular level. Special structures like pseudopodia or whip like flagella or hair like cilia performlocomotion.In some,myonemes are useful in locomotion. Nutrition is holozoic or holophytic or osmotrophic (saprobic or parasitic).Digestion is intracellular. In some like Euglena,nutrition is miaotrophic,perform more than one type of nutrition.

Symmetry in biology

Symmetry in biology

Symmetry in biology
Symmetry in biology is the balanced distribution of duplicate body parts or shapes. In nature and biology, symmetry is approximate. For example, plant leaves, while considered symmetrical, rarely match up exactly when folded in half. Symmetry creates a class of patterns in nature, where the near-repetition of the pattern element is by reflection or rotation. The body plans of most multicellular organisms exhibit some form of symmetry, whether radial symmetry, bilateral symmetry or "spherical symmetry". A small minority, notably the sponges, exhibit no symmetry. This video is targeted to blind users. Attribution: Article text available under CC-BY-SA Creative Commons image source in video

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. The rotifers (Rotifera, commonly called wheel animals) make up a phylum of microscopic and near-microscopic pseudocoelomate animals. They were first described by Rev. John Harris in 1696, and other forms were described by Antonie van Leeuwenhoek in 1703. Most rotifers are around 0.1–0.5 mm long (although their size can range from 50 µm to over 2 mm), and are common in freshwater environments throughout the world with a few saltwater species; for example, those of genus Synchaeta. Some rotifers are free swimming and truly planktonic, others move by inchworming along a substrate, and some are sessile, living inside tubes or gelatinous holdfasts that are attached to a substrate. About 25 species are colonial (e.g., Sinantherina semibullata), either sessile or planktonic. Rotifers are an important part of the freshwater zooplankton, being a major foodsource and with many species also contributing to the decomposition of soil organic matter. Most species of the rotifers are cosmopolitan, but there are also some endemic species, like Cephalodella vittata to Lake Baikal. Recent barcoding evidence, however, suggests that some 'cosmopolitan' species, such as Brachionus plicatilis, B. calyciflorus, Lecane bulla, among others, are actually species complexes. In some recent treatments, rotifers are placed with acanthocephalans in a larger clade called Syndermata.
