Castalia martensi is a species of freshwater mussel in the family Hyriidae. It is endemic to Brazil. [1]
Castalia, in ancient Greek and Roman literature,. was the name of a spring near Delphi, sacred to the Muses; it is also known as the Castalian Spring. It is said to have derived its name from Castalia, a naiad-nymph, daughter of the river-god Achelous, who is said to have flung herself into the spring when pursued by the god Apollo.
4769 Castalia is a near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 1.4 kilometers in diameter and was the first asteroid to be modeled by radar imaging. It was discovered on 9 August 1989, by American astronomer Eleanor Helin (Caltech) on photographic plates taken at Palomar Observatory in California. It is named after Castalia, a nymph in Greek mythology. It is also a Mars- and Venus-crosser asteroid.
Comet Elst–Pizarro is a body that displays characteristics of both asteroids and comets, and is the prototype of active asteroids. Its orbit keeps it within the asteroid belt, yet it displayed a dust tail like a comet while near perihelion in 1996, 2001, and 2007.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as only consisting of living members kept in captivity or as a naturalized population outside its historic range. Classification requires exhaustive surveys conducted within the species' known habitat with consideration given to seasonality, time of day, and life cycle. Once a species is classified as EW, the only way for it to be downgraded is through reintroduction.
