Buzzle – Zoology Terms – Glossary of Biology Terms and Definitions http://www.buzzle.com/articles/biology-terms-glossary-of-biology-terms-and- definitions.html#ZoologyGlossary Biology is the branch of science concerned with the study of life: structure, growth, functioning and evolution of living things. This discipline of science comprises three sub-disciplines that are botany (study of plants), Zoology (study of animals) and Microbiology (study of microorganisms). This vast subject of science involves the usage of myriads of biology terms, which are essential to be comprehended correctly. People involved in the science field encounter innumerable jargons during their study, research or work. Moreover, since science is a part of everybody's life, it is something that is important to all individuals. A Abdomen: Abdomen in mammals is the portion of the body which is located below the rib cage, and in arthropods below the thorax. It is the cavity that contains stomach, intestines, etc. Abscission: Abscission is a process of shedding or separating part of an organism from the rest of it. Common examples are that of, plant parts like leaves, fruits, flowers and bark being separated from the plant. Accidental: Accidental refers to the occurrences or existence of all those species that would not be found in a particular region under normal circumstances. Acclimation: Acclimation refers to the morphological and/or physiological changes experienced by various organisms to adapt or accustom themselves to a new climate or environment. Active Transport: The movement of cellular substances like ions or molecules by traveling across the membrane, towards a higher level of concentration while consuming energy. -
Towards a Management Hierarchy (Classification) for the Catalogue of Life
TOWARDS A MANAGEMENT HIERARCHY (CLASSIFICATION) FOR THE CATALOGUE OF LIFE Draft Discussion Document Rationale The Catalogue of Life partnership, comprising Species 2000 and ITIS (Integrated Taxonomic Information System), has the goal of achieving a comprehensive catalogue of all known species on Earth by the year 2011. The actual number of described species (after correction for synonyms) is not presently known but estimates suggest about 1.8 million species. The collaborative teams behind the Catalogue of Life need an agreed standard classification for these 1.8 million species, i.e. a working hierarchy for management purposes. This discussion document is intended to highlight some of the issues that need clarifying in order to achieve this goal beyond what we presently have. Concerning Classification Life’s diversity is classified into a hierarchy of categories. The best-known of these is the Kingdom. When Carl Linnaeus introduced his new “system of nature” in the 1750s ― Systema Naturae per Regna tria naturae, secundum Classes, Ordines, Genera, Species …) ― he recognised three kingdoms, viz Plantae, Animalia, and a third kingdom for minerals that has long since been abandoned. As is evident from the title of his work, he introduced lower-level taxonomic categories, each successively nested in the other, named Class, Order, Genus, and Species. The most useful and innovative aspect of his system (which gave rise to the scientific discipline of Systematics) was the use of the binominal, comprising genus and species, that uniquely identified each species of organism. Linnaeus’s system has proven to be robust for some 250 years. The starting point for botanical names is his Species Plantarum, published in 1753, and that for zoological names is the tenth edition of the Systema Naturae published in 1758. -

Glossary - Zoology - Intro
1 Glossary - Zoology - Intro Abdomen: Posterior part of an arthropoda’ body; in vertebrates: abdomen between thorax and pelvic girdle. Acoelous: See coelom. Amixia: A restriction that prevents general intercrossing in a species leading to inbreeding. Anabiosis: Resuscitation after apparent death. Archenteron: See coelom. Aulotomy: Capacity of separating a limb; followed by regeneration; used also for asexual reproduction; see also fissipary (in echinodermata and platyhelminthes). Basal Lamina: Basal plate of developing neural tube; the noncellular, collagenous layer that separates an epithelium from an underlying layer of tissue; also basal membrane. Benthic: Organisms that live on ocean bottoms. Blastocoel: See coelom. Blastula: Stage of embryonic development, at / near the end of cleavage, preceding gastrulation; generally consisting of a hollow ball of cells (coeloblastula); if no blastoceol is present it is termed stereoblastulae (arise from isolecithal and moderately telolecithal ova); in meroblastic cleavage (only the upper part of the zygote is divided), the blastula consists of a disc of cells lying on top of the yolk mass; the blastocoel is reduced to the space separating the cells from the yolk mass. Blastoporus: The opening into the archenteron (the primitive gastric cavity of the gastrula = gastrocoel) developed by the invagination of the blastula = protostoma. Cephalisation: (Gk. kephale, little head) A type of animal body plan or organization in which one end contains a nerve-rich region and functions as a head. Cilium: (pl. cilia, long eyelash) A short, centriole-based, hairlike organelle: Rows of cilia propel certain protista. Cilia also aid the movement of substances across epithelial surfaces of animal cells. Cleavage: The zygote undergoes a series of rapid, synchronous mitotic divisions; results in a ball of many cells. -
Vertebrates and Invertebrates
Vertebrates and invertebrates The animal kingdom is divided into two groups: vertebrates and invertebrates. Vertebrates have been around for millions of years but have evolved and changed over time. The word vertebrate means “having a backbone." Many animals have backbones. You have a backbone. So does a cow, a whale, a fish, a frog, and a bird. Vertebrates are animals that have a backbone. Most animals have a backbone that is made of bones joined together to form a skeleton. Our skeleton gives us our shape and allows us to move. Mammals, fish, birds, reptiles, and amphibians have Vertebrae backbones so they are all vertebrates. Each bone that makes up the backbone Scientists classify vertebrates into five classes: is called a vertebra. These are the • Mammals building blacks that form the backbone, • Fish also known as the spinal cord. The • Birds vertebrae protect and support your • Reptiles spine. Without a backbone, you would not • Amphibians be able to move any part of your body. Animals without a backbone are called invertebrates. Most The human animals are invertebrates. In fact, 95% of all living creatures backbone has 26 on Earth are invertebrates. vertebrae. Arthropods are the largest group of invertebrates. Insects make up a large part of this group. All insects, such as ladybugs, ants, grasshoppers, and bumblebees have three body sections and six legs. Most arthropods live on land, but some of these fascinating creatures live in water. Lobsters, crabs, and shrimp are arthropods that live in the oceans. Many invertebrates have skeletons on the outside of their A frog only has bodies called exoskeletons. -
Fun Facts: Incredible Invertebrates 40 Minutes Age 7-11
Fun Facts: Incredible Invertebrates 40 minutes Age 7-11 1. Invertebrates are animals that do not have a backbone. Some common invertebrates are worms, snails, corals, sponges, insects, jellyfish, and crustaceans (Brsuca and Brusca, 2003). 2. Invertebrates first evolved during the Cambrian Period, over 540 million years ago (Brusca and Brusca, 2003) 3. Over 95% of the 1.4 million known animal species are invertebrates (Smithsonian, 2018) 4. The largest invertebrate is the colossal squid which can weigh over 500kg and reach lengths of up to 14m (Ravaiolo and Youngster, 2012). 5. Corals are sessile invertebrates, meaning they are fixed in one place and unable to relocate. Corals grow at different rates, with some growing up to 10cm in one year and others only growing 0.3cm in one year (Barnes, 1987). 6. Many species of marine worms, such as feather duster and Christmas tree worms, survive by hiding their body in a tube attached to the reef. They feed by extending their gills into the water and catching phytoplankton and other microscopic organisms in the water column (NOAA, 2020). 7. Sea stars and sea urchins are some important species of invertebrates that have specialized organs called tube feet, which allow them to move and feed. The tube feet have two special types of cells. The first type of cell releases a glue-like substance that allows the tube feet to stick and hold onto different structures. The second type of cell releases a substance that breaks down the glue-like substance and allows the tube feet to release from the structure (Flammang et al., 2005). -
Cnidarian Immunity and the Repertoire of Defense Mechanisms in Anthozoans
biology Review Cnidarian Immunity and the Repertoire of Defense Mechanisms in Anthozoans Maria Giovanna Parisi 1,* , Daniela Parrinello 1, Loredana Stabili 2 and Matteo Cammarata 1,* 1 Department of Earth and Marine Sciences, University of Palermo, 90128 Palermo, Italy; [email protected] 2 Department of Biological and Environmental Sciences and Technologies, University of Salento, 73100 Lecce, Italy; [email protected] * Correspondence: [email protected] (M.G.P.); [email protected] (M.C.) Received: 10 August 2020; Accepted: 4 September 2020; Published: 11 September 2020 Abstract: Anthozoa is the most specious class of the phylum Cnidaria that is phylogenetically basal within the Metazoa. It is an interesting group for studying the evolution of mutualisms and immunity, for despite their morphological simplicity, Anthozoans are unexpectedly immunologically complex, with large genomes and gene families similar to those of the Bilateria. Evidence indicates that the Anthozoan innate immune system is not only involved in the disruption of harmful microorganisms, but is also crucial in structuring tissue-associated microbial communities that are essential components of the cnidarian holobiont and useful to the animal’s health for several functions including metabolism, immune defense, development, and behavior. Here, we report on the current state of the art of Anthozoan immunity. Like other invertebrates, Anthozoans possess immune mechanisms based on self/non-self-recognition. Although lacking adaptive immunity, they use a diverse repertoire of immune receptor signaling pathways (PRRs) to recognize a broad array of conserved microorganism-associated molecular patterns (MAMP). The intracellular signaling cascades lead to gene transcription up to endpoints of release of molecules that kill the pathogens, defend the self by maintaining homeostasis, and modulate the wound repair process. -
Cnidarians Are Some of the Most Conspicuous and Colorful Tidepool Animals, Yet They Are Often Overlooked and Unappreciated
Page 1 of 1 Biology 122L – Invertebrate zoology lab Cnidarian diversity lab guide Author: Allison J. Gong Figure source: Brusca and Brusca, 2003. Invertebrates, second edition. Sinauer Associates, Inc. INTRODUCTION Cnidarians are some of the most conspicuous and colorful tidepool animals, yet they are often overlooked and unappreciated. To the untrained eye their radial symmetry makes cnidarians seem more plantlike than animallike, and the colonial forms of hydroids often have a "bushy" appearance that reinforces that mistaken first impression. However, cnidarians are indeed animals, and a closer examination of their bodies and behaviors will prove it to you. The generalized body plan of a cnidarian consists of an oral disc surrounded by a ring (or rings) of long tentacles, atop a column that contains the two-way gut, or coelenteron. This body plan can occur in either of two forms: a polyp, in which the column is attached to a hard surface with the oral disc and tentacles facing into the water; and a medusa, in which the column is (usually) unattached and the entire organism is surrounded by water. In the medusa phase the column is flattened and generally rounded to form the bell of the pelagic medusa. Cnidarian tentacles are armed with cnidocytes, cells containing the stinging capsules, or cnidae, that give the phylum its name. Cnidae are produced only by Page 2 of 2 cnidarians, although they can occasionally be found in the cerata of nudibranch molluscs that feed on cnidarians: through a process that is not understood, some nudibranchs are able to ingest cnidae from their prey and sequester them, unfired, in their cerata for defense against their own predators. -
Styles of Reasoning in Early to Mid-Victorian Life Research: Analysis:Synthesis and Palaetiology
Journal of the History of Biology (2006) Ó Springer 2006 DOI 10.1007/s10739-006-0006-4 Styles of Reasoning in Early to Mid-Victorian Life Research: Analysis:Synthesis and Palaetiology JAMES ELWICK Science and Technology Studies Faculties of Arts and Science and Engineering York University 4700 Keele St. M3J 1P3 Toronto, ON Canada E-mail: [email protected] Abstract. To better understand the work of pre-Darwinian British life researchers in their own right, this paper discusses two different styles of reasoning. On the one hand there was analysis:synthesis, where an organism was disintegrated into its constituent parts and then reintegrated into a whole; on the other hand there was palaetiology, the historicist depiction of the progressive specialization of an organism. This paper shows how each style allowed for development, but showed it as moving in opposite directions. In analysis:synthesis, development proceeded centripetally, through the fusion of parts. Meanwhile in palaetiology, development moved centrifugally, through the ramifying specialization of an initially simple substance. I first examine a com- munity of analytically oriented British life researchers, exemplified by Richard Owen, and certain technical questions they considered important. These involved the neu- rosciences, embryology, and reproduction and regeneration. The paper then looks at a new generation of British palaetiologists, exemplified by W.B. Carpenter and T.H. Huxley, who succeeded at portraying analysts’ questions as irrelevant. The link between styles of reasoning and physical sites is also explored. Analysts favored museums, which facilitated the examination and display of unchanging marine organisms while providing a power base for analysts. I suggest that palaetiologists were helped by vivaria, which included marine aquaria and Wardian cases. -
