In anatomy, the tomium is the sharp cutting edge of the beak of a bird or turtle. Sometimes the edge is serrated for tearing through flesh or seaweed (in the case of sea turtles). Snapping turtle tomia can be dangerous because their bites are swift and powerful.

Anatomy The study of the structure of organisms and their parts

Anatomy is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science which deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated over immediate (embryology) and long (evolution) timescales. Anatomy and physiology, which study (respectively) the structure and function of organisms and their parts, make a natural pair of related disciplines, and they are often studied together. Human anatomy is one of the essential basic sciences that are applied in medicine.

Chelydridae family of turtles

The Chelydridae are a family of turtles that has seven extinct and two extant genera. The extant genera are the snapping turtles Chelydra and Macrochelys. Both are endemic to the Western Hemisphere. The extinct genera are Acherontemys, Chelydrops, Chelydropsis, Emarginachelys, Macrocephalochelys, Planiplastron, and Protochelydra.

Reptile class of animals

Reptiles are tetrapod animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of modern amphibians, is called herpetology.

Turtle order of reptiles

Turtles are diapsids of the order Testudines characterized by a special bony or cartilaginous shell developed from their ribs and acting as a shield. "Turtle" may refer to the order as a whole or to fresh-water and sea-dwelling testudines. The order Testudines includes both extant (living) and extinct species. The earliest known members of this group date from 220 million years ago, making turtles one of the oldest reptile groups and a more ancient group than snakes or crocodilians. Of the 356 known species alive today, some are highly endangered.

European turtle dove species of bird

The European turtle dove is a member of the bird family Columbidae, the doves and pigeons.

Sauria suborder of reptiles

The clade Sauria was traditionally a suborder for lizards which originally comprised crocodilians too. It has been redefined as the group containing the most recent common ancestor of archosaurs and lepidosaurs and all its descendants; as such it was commonly thought that Sauria is a crowned-base grouping of diapsids. However, recent genomic studies and comprehensive studies in the fossil record suggest that turtles are closely related to archosaurs, not to parareptiles as previously thought. Sauria can be seen as a crowned-group of all modern reptiles within the larger total group Sauropsida, which also contains various stem-reptile groups.

Diapsid clade of tetrapods that developed two holes (temporal fenestra) in each side of their skulls, about 300 million years ago

Diapsids are a group of amniote tetrapods that developed two holes in each side of their skulls about 300 million years ago during the late Carboniferous period. The diapsids are extremely diverse, and include all crocodiles, lizards, snakes, tuatara, turtles, and birds. Although some diapsids have lost either one hole (lizards), or both holes, or have a heavily restructured skull, they are still classified as diapsids based on their ancestry. At least 7,925 species of diapsid reptiles exist in environments around the world today.

Sauropsida Sauropsida is a taxonomic clade that includes reptiles and birds. All Tetrapoda except Amphibia are Amniota, and all Amniota except Synapsida, including Mammalia, are Sauropsida.

Sauropsida is a taxonomic clade that includes both reptiles and birds. All Tetrapoda except Amphibia are Amniota, and all Amniota except Synapsida, including Mammalia, are Sauropsida. This clade includes Parareptilia and other extinct clades. All living sauropsids are members of the subgroup Diapsida, the Parareptilia having died out 200 million years ago. The term originated in 1864 with Thomas Henry Huxley, who grouped birds with reptiles based on fossil evidence.

Oriental turtle dove species of bird

The oriental turtle dove or rufous turtle dove is a member of the bird family Columbidae. The species is has a wide native distribution range from Europe, east across Asia to Japan. The populations show variations in the patterning of plumage and have been designated into at least six named subspecies. Populations in the higher latitudes tend to migrate south in winter while those closer to the tropics are sedentary. Vagrants have been recorded in North America. The species is predominantly granivorous and forages on the ground.

Alligator snapping turtle heaviest freshwater turtle in the world

The alligator snapping turtle is a species of turtle in the family Chelydridae. The species is native to freshwater habitats in the United States. M. temminckii is one of the heaviest freshwater turtles in the world. It is often associated with, but not closely related to, the common snapping turtle, which is in the genus Chelydra. The specific epithet temminckii is in honor of Dutch zoologist Coenraad Jacob Temminck.

<i>The Phoenix and the Turtle</i> poem by Shakespeare

The Phoenix and the Turtle is an allegorical poem about the death of ideal love by William Shakespeare. It is widely considered to be one of his most obscure works and has led to many conflicting interpretations. It has also been called "the first great published metaphysical poem". The title "The Phoenix and the Turtle" is a conventional label. As published, the poem was untitled. The "turtle" is the Turtledove, not the shelled reptile.

Zenaida dove species of bird

The zenaida dove is a member of the bird family Columbidae, which includes doves and pigeons. It is the national bird of Anguilla, where it is commonly referred to as a turtle dove. It lays two white eggs on a flimsy platform built on a tree or shrub. It also nests in rock crevices and on grassy vegetation if no predators are present. It has been recorded that some birds have up to 4 broods per year. Eggs take approximately two weeks to hatch, and the young chicks typically fledge after only two weeks in the nest. Parents feed the young pigeon's milk, a nutrient rich substance regurgitated from its crop.
