InsectInsects (from Latininsectum) are invertebrates of the classInsecta. They are the largest group within the arthropod phylum. Insects have an exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a brain and a ventral nerve cord. Insects breathe air through a syst...
Developmental biologyDevelopmental biology is the scientific study of the processes by which animals and plants grow and develop. The field of developmental biology is further defined by its study of phenomena such as regeneration, asexual reproduction, metamorphosis, and the growth and differentiation of stem cells within the adult organism.
AmphibianAmphibians are ectothermic, anamniotic, four-limbedvertebrateanimals that constitute the classAmphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant (living) amphibians belong to the monophyleticsubclassLissamphibia, with three living orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibia...
TunicateMarine animals, subphylum of chordatesTunicates are marine invertebrates belonging to the subphylumTunicata ( ). This grouping is part of the Chordata, a phylum which includes all animals with dorsal nerve cords and notochords (including vertebrates). The subphylum was at one time called Urochordata, and the term urochordates is still sometimes used for these animals. Despite their simple appearance and very different adult form, their close relationship to the vertebrates is certain. Both groups are chordates, ...
Biological processA biological process is a process necessary for an organism to live, and therefore shapes its capacity to interact with its environment. Biological processes are made of many chemical reactions or other events that are involved in the persistence and transformation of life forms. RegulationRegulation of biological processes occurs when any process is modulated in its frequency, rate or extent. Biological processes are regulated by many means; examples include the control of gene expression, protein modification ...
FishA fish is an aquatic, anamniotic, gill-bearing vertebrateanimal with a tough cranium to protect the brain, but lacking limbs with digits. Fish can be grouped into the more basaljawless fish and the more common jawed fish, the latter including all livingcartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break from the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group that includes all vertebrates except tetr...
EchinodermAn echinoderm () is any animal of the phylum Echinodermata (), which includes starfish, brittle stars, sea urchins, sand dollars and sea cucumbers, as well as the sessile sea lilies or "stone lilies". While bilaterally symmetrical as larvae, as adults echinoderms are recognisable by their usually five-pointed radial symmetry (pentamerous symmetry), and are found on the sea bed at every ocean depth from the intertidal zone to the abyssal zone. The phylum contains about 7,600 living species, making it the second-l...
CrustaceanCrustaceans (from Latin word "crustacea" meaning: "those with shells" or "crusted ones") are mandibulatearthropods that are traditionally a part of the paraphyleticsubphylumCrustacea (). Crustaceans are mainly aquatic, including decapods (shrimps, prawns, crabs, lobsters, and crayfish), seed shrimps, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, opossum shrimps, amphipods and mantis shrimp. It is now well accepted that hexapods (insects and entognathans) are cladistically crustaceans, ...
CnidariaCnidaria ( ) is a phylum of animals containing over 11,000 species of aquaticinvertebrates found both in freshwater and marine environments (predominantly the latter), including jellyfish, hydroids, sea anemones, corals and some of the smallest marine parasites. Their distinguishing features are a decentralizednerve net distributed throughout a gelatinous body, and the presence of cnidocytes or cnidoblasts, specialized cells with ejectable organelles used mainly for envenomation and capturing prey. Their bodies ...
NutritionNutrition is the biochemical and physiological process by which an organism uses food and water to support its life. The intake of these substances provides organisms with nutrients (divided into macro- and micro-) which can be metabolized to create energy and chemical structures; too much or too little of an essential nutrient can cause malnutrition. Nutritional science, the study of nutrition as a hard science, typically emphasizes human nutrition. The type of organism determines what nutrients it needs and ho...
BehaviorBehavior (American English) or behaviour (British English) is the range of actions of organisms, individuals, systems or artificial entities in some environment. These systems can include other systems or organisms as well as the inanimate physical environment. It is the computed response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary. While some behavior is produced in response to an organism's enviro...
MolluscaMollusca is a phylum of protostomicinvertebrateanimals, whose members are known as molluscs or mollusks (). 86,600 extantspecies of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed extant species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. They are highly diverse, n...*As an Amazon Associate I earn from qualifying purchases.
