Schmidtea lugubris is a species of freshwater flatworm, a dugesiid triclad found in Europe.
S. lugubris is slender in shape. The head is blunt and rounded at full growth, but medium-sized individuals have lateral lobes forming a triangular shape. There are two eyes. The auricles of the head are a translucent grey color, but the rest of the backside is a dark brown. [1]
S. lugubris preys mainly on oligochaetes and gastropods. [2]
Orrorin tugenensis is a postulated early species of Homininae, estimated at 6.1 to 5.7 million years ago and discovered in 2000. It is not confirmed how Orrorin is related to modern humans. Its discovery was used to argue against the hypothesis that australopithecines are human ancestors, although this remains the most prevalent hypothesis of human evolution as of 2012.
A planarian is one of the many flatworms of the traditional class Turbellaria. It usually describes free-living flatworms of the order Tricladida (triclads), although this common name is also used for a wide number of free-living platyhelminthes. Planaria are common to many parts of the world, living in both saltwater and freshwater ponds and rivers. Some species are terrestrial and are found under logs, in or on the soil, and on plants in humid areas.
Planaria is a genus of planarians in the family Planariidae. When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual.
The Carib grackle is a New World tropical blackbird, a resident breeder in the Lesser Antilles and northern South America east of the Andes, from Colombia east to Venezuela and northeastern Brazil. There are eight subspecies, of which the most widespread is the nominate subspecies of Trinidad and the South American mainland. This subspecies was introduced to Tobago in 1905 and is now common there.
The arboreal salamander is a species of climbing salamander. An insectivore, it is native to California and Baja California, where it is primarily associated with oak and sycamore woodlands, and thick chaparral.
Dugesia is a genus of dugesiid triclads that contains some common representatives of the class Turbellaria. These common flatworms are found in freshwater habitats of Africa, Eurasia, and Australia. Dugesia is best known to non-specialists because of its regeneration capacities.
Caranx lugubris, the black jack, black trevally, black kingfish, coal fish or black ulua, is a species of large ocean fish in the jack family Carangidae. The species has a circumtropical distribution, found in oceanic, offshore waters of the tropical zones of the Pacific, Atlantic and Indian Oceans. The species is particularly prevalent around offshore islands such as the Caribbean islands in the Atlantic, Hawaii and French Polynesia in the Pacific and the Seychelles and Maldives in the Indian Ocean. Black jack are rare in shallow waters, preferring deep reefs, ledges and seamounts in clear waters. The species is easily distinguished by its black to grey fins and jet black scutes, with the head having a steep profile near the snout. The largest recorded length is 1 m and weight of 17.9 kg. The black jack lives either individually or in small schools, and is known to school with other species. It is a predatory fish, taking a variety of fish, crustaceans and molluscs as prey. Sexual maturity is reached at 34.6 cm in females and 38.2 cm in males, with spawning taking place between February and September in the Caribbean. The early life history of the species is very poorly understood. Black jack are of high importance to many island fisheries, but are rarely encountered in most continental fisheries. The species has a reputation as a gamefish, and is variably considered a terrible or excellent food fish, although several cases of ciguatera poisoning have been attributed to the species. The species was initially named Caranx ascensionis by Georges Cuvier, however several issues with the use of this name have seen Felipe Poey's name Caranx lugubris become the valid scientific name.
Lepidodactylus lugubris, known as the mourning gecko or common smooth-scaled gecko, is a species of lizard, a gecko of the family Gekkonidae.
The fork-tailed drongo-cuckoo is a species of cuckoo that resembles a black drongo. It is found resident mainly in peninsular India in hill forests although some specimens are known from the Himalayan foothills. It can be easily distinguished by its straight beak and the white barred vent. It has a deeply forked tail often having a white spot on the back of the head. The song has been described as a series of 5 or 6 whistling "pip-pip-pip-pip-pip-" notes rising in pitch with each "pip".
The Abyssinian wheatear, or Abyssinian black wheatear, is a species of bird in the family Muscicapidae. It is found from Ethiopia to southern Kenya and northeastern Tanzania.
Schmidtea mediterranea is a freshwater triclad that lives in southern Europe and Tunisia. It is a model for regeneration, stem cells and development of tissues such as the brain and germline.
Dugesiidae is a family of freshwater planarians distributed worldwide. The type genus is Dugesia Girard, 1850.
Girardia tigrina, known as the brown planarian or the immigrant triclad flatworm, is a species of dugesiid native to the Americas. It has been accidentally introduced into Europe and Japan.
Schmidtea polychroa is a species of freshwater flatworm, a dugesiid triclad that inhabits the shallow mesotrophic or eutrophic waters of rivers and lakes of Europe. It is also present in North America, where it has been introduced at least in the Saint Lawrence river system. It is an animal with a limited dispersion capability.
Cura is a genus of freshwater flatworm (triclad)s belonging to the family Dugesiidae.
Spathula is a genus of dugesiid triclad. Its species are found in Australia and New Zealand.
Weissius capaciductus is a species of dugesiid triclad found in Australia. It is the only species in the monotypic genus Weissius.
Dimarcusidae is a family of triclads found mostly in freshwater habitats of caves, although at least one species, Rhodax evelinae, occurs in surface waters. Currently the family contains only seven species distributed in five genera, although the total number of species is thought to be much higher.
Dendrocoelopsis piriformis is a species of freshwater triclad in the family Dendrocoelidae. It is found in Alaska.
Carpophilus lugubris, commonly known as the dusky sap beetle, is a species of beetle in the genus Carpophilus. It is an agricultural pest of corn and tomato.
