Furca, a prehistoric arthropod; Furca (springtail), an anatomical structure in springtail entognaths. Caudal furca ("tail fork"), part of the telson of some crustaceans; Furcula, the wishbone of birds and some dinosaurs; Furcula a genus of Noctuid moths; Any small forked structure of animal anatomy
Furca fossils have been found in sediments indicative of shallow marine habitats. Since appendages and other body parts are unknown, no firm conclusions can be made of the biology of Furca. However, comparisons to other marrellomorphs and living arthropods such as horseshoe crabs suggest a benthic marine lifestyle: dwelling on the sea floor. [2]
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
In biological classification, class (Latin: classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders. [a] Other well-known ranks in descending order of size are life, domain, kingdom, phylum, order, family, genus, and species, with class ranking between phylum and order. [1]
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
The common name of the family is fork-tongued frogs. [ 1 ] The Dicroglossidae were previously considered to be a subfamily in the family Ranidae , but their position as a family is now well established.
The etymology of the word "morphology" is from the Ancient Greek μορφή (morphḗ), meaning "form", and λόγος (lógos), meaning "word, study, research". [2] [3]While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist ...
C. furca has long spines, and is an "armoured" species with a theca of thick cellulose plates. The cells are nearly flat, with the ventral side concave and the dorsal side being convex. The cells are nearly flat, with the ventral side concave and the dorsal side being convex.
