- Animalia : The taxonomic kingdom including all animals.
- Animal : A multicellular organism that feeds on other organisms, and is distinguished from plants, fungi, and unicellular organisms.

- Bubble-eye Goldfish : A breed of Goldfish that sports large fluid filled sacs beneath the eyes, a twin tail, and lacks a dorsal fin.
- Carbohydrate metabolism : The various biochemical processes responsible for the formation, breakdown and interconversion of carbohydrates in living organisms.
- Catabolism : The metabolic process that breaks down molecules into smaller units.
- Cell membrane : The outer surface of a cell which encloses its contents.
- Cellular respiration : A series of metabolic processes by which living cells produce energy through the oxidation of organic substances.
- Cloning : The generation of genetically identical organisms, using cells derived from an original cell by fission (one cell dividing into two cells) or by mitosis (cell nucleus division with each chromosome splitting into two).
- Cobalt : A hard, lustrous, grey metal, a chemical element with symbol Co and atomic number 27.
- Comet (goldfish) : A goldfish variety developed in 1880 by Hugo Mulertt, and has become one of the best selling aquarium fish since.
- Common Goldfish : Common ancestor for most "fancy goldfish". Color is the only difference between the Common Goldfish and its ancestor, the Prussian Carp.
- Cryogenics : The study of the production and behaviour of materials at very low temperature (below –150 °C, –238 °F or 123 K).
- Cryopreservation : A process where cells or whole tissues are preserved by cooling to low sub-zero temperatures.
- Cryoprotectant : A substance that protects biological tissue from freezing damage.
- Disease : A condition of the body in which one or more of its components fail to operate properly, resulting in disability, pain or other forms of suffering, or behavioral aberrations.
- Embryo : An organism in its earliest phase of development.
- Enzyme : A protein that catalyzes (i.e. accelerate) chemical reactions.
- Eukaryota : is a domain formed by all living beings, from unicellular to very complex individuals with many different types of cells carrying particular functions, that are always constituted by cells where there is a nucleus, with various organelles, enclosed by a membrane that separates its content from the surrounding cytoplasm.
- Eukaryote : An organism that is composed of one or more cells containing cell nuclei.
- Evolutionary psychology : The comparative study of the nervous system and its relation to behaviour across species.
- Fish : Any aquatic vertebrate animal that is typically ectothermic (or cold-blooded), covered with scales, and equipped with two sets of paired fins and several unpaired fins.
- Food web : Complex of interrelated food chains in an ecological community.
- Gene : The functional unit of heredity.
- Health : The default state of an organism under optimal conditions, a state characterized by the absence of disease and by the slowest natural rate of senescing.
- Homo erectus : Extinct species of the genus Homo, believed to have been the first hominin, that lived from about 1.8 million to 250,000 years ago.
- Information : Knowledge of specific events or situations that has been gathered or received by communication; intelligence or news.
- Internal energy : Energy of a system in absence of interaction of the system with external fields
- Kingdom (biology) : The second highest level taxon of organisms in scientific classification and biological taxonomy.
- Microorganism : A 'germ', an organism that is too small to be seen individually with the naked eye.
- Multicellular organism : Organism consisting of more than one cell, and having differentiated cells that perform specialized functions in the organism.
- Mycology : The branch of microbiology concerned with the study and effects of fungi
- Nymph (goldfish) : A breed of goldfish descended from the Veiltail and Fantail.
- Organism : An individual living individual: a complex, adaptive physical system that acts a integrated unit that sustains metabolism and reproduces progeny that resemble it.
- Perpetual motion machine : A hypothetical machine that produces more energy than it consumes.
- Plant (organism) : A eukaryotic organism, grouped into the kingdom Plantae, that typically synthesizes nutrients through photosynthesis and possesses the inability to voluntarily move.
- Prokaryote : Single celled organism with no membrane-bound organelles.
- Protein : A polymer of amino acids; basic building block of living systems.
- Protist : A unicellular organism grouped into the kingdom Protista that may have characteristics of plants and/or animals.
- Quantization : Replacement of a classical variable by a quantum mechanical operator; phenomenon that energy is discontinuous.
- Quorum sensing : Ability of populations of bacteria to communicate and coordinate their behavior via inter-cellular and inter-species signaling molecules.
- Shubunkin : Also known as "poor mans Koi", the Shubunkin is a breed of goldfish first developed in Japan in the 1900's.
- Sun : The star that defines our solar system.
- Thermodynamics : The statistical description of the properties of molecular systems
- Transposon : Blocks of conserved DNA that can occasionally move to different positions within the chromosomes of a cell.
- Zero-point energy : The lowest possible energy that a quantum mechanical physical system may possess; it is the energy of the ground state of the system.
