** Eunectes murinus, the green anaconda, the largest species, is found east of the Andes in Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, Brazil and on the island of Trinidad.

** Eunectes notaeus, the yellow anaconda, a smaller species, is found in eastern Bolivia, southern Brazil, Paraguay and northeastern Argentina.

** Eunectes deschauenseei, the dark-spotted anaconda, is a rare species found in northeastern Brazil and coastal French Guiana.

** Eunectes beniensis, the Bolivian anaconda, the most recently defined species, is found in the Departments of Beni and Pando in Bolivia.

** Tarski's theorem: For every infinite set A, there is a bijective map between the sets A and A × A.

** The Cartesian product of any family of nonempty sets is nonempty.

** König's theorem: Colloquially, the sum of a sequence of cardinals is strictly less than the product of a sequence of larger cardinals.

** Hausdorff maximal principle: In any partially ordered set, every totally ordered subset is contained in a maximal totally ordered subset.

** For every non-empty set S there is a binary operation defined on S that makes it a group.

** Tychonoff's theorem stating that every product of compact topological spaces is compact.

** In the product topology, the closure of a product of subsets is equal to the product of the closures.

** If S is a set of sentences of first-order logic and B is a consistent subset of S, then B is included in a set that is maximal among consistent subsets of S. The special case where S is the set of all first-order sentences in a given signature is weaker, equivalent to the Boolean prime ideal theorem ; see the section " Weaker forms " below.

** Any union of countably many countable sets is itself countable.

** If the set A is infinite, then there exists an injection from the natural numbers N to A ( see Dedekind infinite ).

** Every infinite game in which is a Borel subset of Baire space is determined.

** The Vitali theorem on the existence of non-measurable sets which states that there is a subset of the real numbers that is not Lebesgue measurable.

** The Lebesgue measure of a countable disjoint union of measurable sets is equal to the sum of the measures of the individual sets.

** The Nielsen – Schreier theorem, that every subgroup of a free group is free.

** Methemoglobinemia in which an abnormal version of hemoglobin accumulates in the blood

** By mid-adolescence or later, a woman may decide that her abnormal genitalia do not need to be changed.

** cellular atypia ( whether or not individual cells look abnormal )

** If the patient is postmenopausal, she usually presents with abnormal uterine bleeding.

** Class Osteichthyes ( bony fishes )

** Spinal canal or spinal cavity, a tube shaped space enclosed in and protected by the bony vertebral column

** Class Acanthodii (" spiny sharks ", sometimes classified under bony fishes ) †

** Class Osteichthyes ( bony fish )

** Operculum ( fish ), a flap of the bony fish covering the gills

** Class Osteichthyes ( bony fish ), which has two subclasses:

** These are two irregular cavities, which extend backward, upward, and lateralward for a variable distance between the two tables of the skull ; they are separated from one another by a thin bony septum, which often deviates to one or other side, with the result that the sinuses are rarely symmetrical.

** Espiritu Creek Trail ( inaccessible-dense overgrowth )

** Description: found at depths up to 183 m ; small ovate white shell, narrowing toward the apex ; sunken spire ; body whorl has spiral grooves at the edges ; narrow aperture

** balance problems, and peripheral vertigo often due to schwannoma and involvement of the inner ear

** Spring roll ( 春捲 cheun gyun ): a roll consisting of various types of vegetables — such as sliced carrot, cabbage, mushroom and wood ear fungus — and sometimes meat are rolled inside a thin flour skin and deep fried.

** Labyrinthectomy ( surgical removal of the whole balance organ ) is more widely available as a treatment but causes total deafness in the affected ear.

** A lab mouse being interviewed while another mouse with a human ear on his back walks by.

** Congenital Preauricular fistula: A small pit in front of the ear.

** Z30: ear is one centimeter long in wheat

** An alternative which is often used is bending a wire or even just using the ring portion of a CBR to put on the earlobe, which stays on by pinching the ear

** Othematoma – between the skin and the layers of cartilage of the ear

** Pinna, the external portion of the ear

** Auriculectomy, surgical removal of the ear

** Auricular branch ( disambiguation ), one of various nerves having to do with the ear or hearing

** Auricular muscles, muscles surrounding the ear

** Rotatory ( torsional ) nystagmus, where the top of the eye rotates towards the affected ear in a beating or twitching fashion, which has a latency and can be fatigued ( the vertigo should lessen with deliberate repetition of the provoking maneuver ).

** Astral Sonic Cannon: Weapon on Lightningborg's chest used to give his enemy ear aches, later involving a laser blast afterwards.

** Osseous ampullae – in the semicircular canals of the mammalian ear
