Invertebrate
Invertebrates are animals that neither develop nor retain a vertebral column (commonly known as a spine or backbone), which evolved from the notochord. It is a paraphyletic grouping including all animals excluding the chordate subphylum Vertebrata, i.e. vertebrates. Nonetheless, almost all invertebrates belong to the monophyletic clade Protostomia, including arthropods, molluscs, annelids, and fla

Megafauna
In zoology, megafauna (from Greek μέγας megas 'large' and Neo-Latin fauna 'animal life') are large animals. The precise definition of the term varies widely, though a common threshold is approximately 45 kilograms (99 lb), this lower end being centered on humans, with other thresholds being more relative to the sizes of animals in an ecosystem. The spectrum of lower-end thresholds ranges from 10 k

Meiobenthos
Meiobenthos, also called meiofauna, are small benthic invertebrates that live in marine or freshwater environments, or both. The term meiofauna loosely defines a group of organisms by their size—larger than microfauna but smaller than macrofauna—rather than by their taxonomy. This fauna includes both animals that turn into macrofauna later in life, and those small enough to belong to the meiobenth

Inspissation
Inspissation (literally meaning "thickening") is the process of increasing the viscosity of a fluid, or even of causing a fluid to solidify, typically by dehydration or otherwise reducing its content of solvents. The term also has been applied to coagulation by heating of some substances such as albumens, or to cooling some substances such as solutions of gelatin or agar. Some forms of inspissati

Modified Triadan system
The modified Triadan system is a scheme of dental nomenclature that can be used widely across different animal species. It is used worldwide among veterinary surgeons.

Litter (zoology)
A litter is the live birth of multiple offspring at one time in animals from the same mother and usually from one set of parents, particularly from three to eight offspring. The word is most often used for the offspring of mammals, but can be used for any animal that gives birth to multiple young. In comparison, a group of eggs and the offspring that hatch from them are frequently called a clutch,

Hearing range
Hearing range describes the frequency range that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal. Sensitivity also varies wi

Mixed-species foraging flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging.

Infanticide (zoology)
In animals, infanticide involves the intentional killing of young offspring by a mature animal of the same species. Animal infanticide is studied in zoology, specifically in the field of ethology.

Metamerism (biology)
In biology, metamerism is the phenomenon of having a linear series of body segments fundamentally similar in structure, though not all such structures are entirely alike in any single life form because some of them perform special functions. In animals, metameric segments are referred to as somites or metameres. In plants, they are referred to as metamers or, more concretely, phytomers.

Monochorionic twins
Monochorionic twins are monozygotic (identical) twins that share the same placenta. If the placenta is shared by more than two (see multiple birth), these are monochorionic multiples. Monochorionic twins occur in 0.3% of all pregnancies. Seventy-five percent of monozygotic twin pregnancies are monochorionic; the remaining 25% are dichorionic diamniotic.

Gray's paradox
Gray's Paradox is a paradox posed in 1936 by British zoologist Sir James Gray. The paradox was to figure out how dolphins can obtain such high speeds and accelerations with what appears to be a small muscle mass. Gray made an estimate of the power a dolphin could exert based on its physiology, and concluded the power was insufficient to overcome the drag forces in water. He hypothesized that dolph

Menstruation is the shedding of the uterine lining (endometrium) in some mammals. It occurs on a regular basis in uninseminated sexually reproductive-age females of certain mammal species.

Gynogenesis
Gynogenesis, a form of parthenogenesis, is a system of asexual reproduction that requires the presence of sperm without the actual contribution of its DNA for completion. The paternal DNA dissolves or is destroyed before it can fuse with the egg. The egg cell of the organism is able to develop, unfertilized, into an adult using only maternal genetic material. Gynogenesis is often termed "sperm par
