The Guanches were the indigenous inhabitants of the Canary Islands in the Atlantic Ocean some 100 kilometres (60 mi) west of the North African coast. They spoke the Guanche language, which went extinct in the 17th century and is believed to have been related to Berber languages.
Lanzarote is a Spanish island, the easternmost of the Canary Islands in the Atlantic Ocean, 125 kilometres off the north coast of Africa and 1,000 kilometres from the Iberian Peninsula. Covering 845.94 square kilometres, Lanzarote is the fourth-largest of the islands in the archipelago. With 152,289 inhabitants at the start of 2019, it is the third most populous Canary Island, after Tenerife and Gran Canaria. Located in the centre-west of the island is Timanfaya National Park, one of its main attractions. The island was declared a biosphere reserve by UNESCO in 1993. The island's capital is Arrecife, which lies on the eastern coastline. It is the smaller main island of the Province of Las Palmas.
The calcareoussponges are members of the animal phylum Porifera, the cellular sponges. They are characterized by spicules made of calcium carbonate, in the form of high-magnesium calcite or aragonite. While the spicules in most species are triradiate, some species may possess two- or four-pointed spicules. Unlike other sponges, calcareans lack microscleres, tiny spicules which reinforce the flesh. In addition, their spicules develop from the outside-in, mineralizing within a hollow organic sheath.
Guanche is an extinct language that was spoken by the Guanches of the Canary Islands until the 16th or 17th century. It died out after the conquest of the Canary Islands as the Guanche ethnic group was assimilated into the dominant Spanish culture. The Guanche language is known today through sentences and individual words that were recorded by early geographers, as well as through several place-names and some Guanche words that were retained in the Canary Islanders' Spanish.
Mykolay Mykolajovych Miklouho-Maclay was a Russian explorer. He worked as an ethnologist, anthropologist and biologist who became famous as one of the earliest scientists to settle among and study indigenous people of New Guinea "who had never seen a European".
Clathrina is a genus of calcareous sponge in the family Clathrinidae. Several species formerly in Clathrina were transferred to the newly erected genera Arturia, Ernstia, Borojevia, and Brattegardia in 2013. The name is derived from the Latin word "clathratus" meaning "latticed".
The Urmetazoan is the hypothetical last common ancestor of all animals, or metazoans. It is universally accepted to be a multicellular heterotroph — with the novelties of a germline and oogamy, an extracellular matrix (ECM) and basement membrane, cell-cell and cell-ECM adhesions and signaling pathways, collagen IV and fibrillar collagen, different cell types, spatial regulation and a complex developmental plan, and relegated unicellular stages.
Arturia canariensis, commonly known as the yellow calcareous sponge, is a species of sponge in the family Clathrinidae. It is found in shallow seas in the Canary Islands, Cape Verde, the Adriatic Sea and the Caribbean Sea. The specific epithet "canariensis" was given to this species because it was first described from Lanzarote in the Canary Islands.
Clathrina chrysea is a species of calcareous sponge from New Caledonia. The species epithet refers to the light yellow colour of the sponge.
Clathrina coriacea is a species of calcareous sponge belonging to the class Calcarea and family Clathrinidae. Species in the genus Clathrina are composed of calcium carbonate tube-like skeletons containing spicules. The sponge can be located in shallow waters widely distributed along North Atlantic coasts, as well as on other coasts.
Clathrina heronensis is a species of calcareous sponge fin the family Clathrinidae and found in the seas around Australia, and in the coastal seas of many islands to her north. It was first described by Gert Wörheide and John Hooper in 1999.
Clathrina laminoclathrata is a species of calcareous sponge from Australia. The species name is in reference to its unusual lamina.
Clathrina primordialis is a species of calcareous sponge from Croatia.
Clathrina sulphurea is an unaccepted scientific name and may refer to three species of calcareous sponge:
Arturia is a genus of calcareous sponge in the family Clathrinidae which contains 14 species. It is named after Arthur Dendy, a prominent researcher of calcareous sponges. It was renamed Arturia in 2017 because the name Arthuria was already assigned to a genus of molluscs.
Ernstia is a genus of calcareous sponges in the family Clathrinidae. The genus was erected in 2013 to contain five species previously assigned to Clathrina. The genus name honors German naturalist Ernst Haeckel for his contributions towards sponge taxonomy and phylogeny.
Clathrina philippina is a species of calcareous sponges from the Philippines.
Aegires sublaevis is a species of sea slug, a nudibranch, a marine, opisthobranch gastropod mollusk in the family Aegiridae.
