Tritonia cucullata Couthouy in Gould, 1852

Marionia cucullata is a species of dendronotid nudibranch. It is a marine gastropod mollusc in the family Tritoniidae.

In biology, a species ( ) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.

Nudibranch order of molluscs

Nudibranchs are a group of soft-bodied, marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown", "marigold", "splendid", "dancer", and "dragon". Currently, about 3,000 valid species of nudibranchs are known.

Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

Punctuated equilibrium theory in evolutionary biology

Punctuated equilibrium is a theory in evolutionary biology which proposes that once species appear in the fossil record the population will become stable, showing little evolutionary change for most of its geological history. This state of little or no morphological change is called stasis. When significant evolutionary change occurs, the theory proposes that it is generally restricted to rare and geologically rapid events of branching speciation called cladogenesis. Cladogenesis is the process by which a species splits into two distinct species, rather than one species gradually transforming into another.

The Reverend Sabine Baring-Gould of Lew Trenchard in Devon, England, was an Anglican priest, hagiographer, antiquarian, novelist, folk song collector and eclectic scholar.

He is remembered particularly as a writer of hymns, the best-known being "Onward, Christian Soldiers" and "Now the Day Is Over". He also translated the carol "Gabriel's Message" from the Basque language to English.

The Beatles English rock band

The Beatles were an English rock band formed in Liverpool in 1960. The line-up of John Lennon, Paul McCartney, George Harrison and Ringo Starr led the band to be regarded as the foremost and most influential in history. With a sound rooted in skiffle, beat and 1950s rock and roll, the group were integral to the evolution of pop music into an art form, and to the development of the counterculture of the 1960s. They often incorporated elements of classical music, older pop forms, and unconventional recording techniques in innovative ways, and in later years experimented with a number of musical styles ranging from pop ballads and Indian music to psychedelia and hard rock. As they continued to draw influences from a variety of cultural sources, their musical and lyrical sophistication grew, and they came to be seen as embodying the era's sociocultural movements.

John Gould English ornithologist and illustrator

John Gould FRS was an English ornithologist and bird artist. He published a number of monographs on birds, illustrated by plates that he produced with the assistance of his wife, Elizabeth Gould, and several other artists including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. He has been considered the father of bird study in Australia and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, On the Origin of Species.
