Geoplana Cananeia
''Geoplana cananeia'' is a species of land planarian belonging to the subfamily Geoplaninae. It is found in areas of the Atlantic Forest on Ilha do Cardoso within Cananéia, Brazil. Description ''Geoplana cananeia'' is a flatworm around 66 mm in length and 5 mm in width. The body has parallel margins; the front tip is rounded and the back tip is pointed. The dorsal side has a yellow-orange band running down the middle, which is flanked on each side by a black stripe, which merges at the back end. A white stripe borders this, which is in turn bordered by a black stripe that merges into a gray band mottled with white, which fades towards the outer margin. The margin is bordered by a thin black stripe. The ventral side is a whitish color with black margins.Ana Laura Almeida and others, ‘Endless forms most beautiful’: taxonomic revision of the planarian ''Geoplana vaginuloides'' (Darwin, 1844) and discovery of numerous congeners (Platyhelminthes: Tricladida), ''Zoological Journal ...

Land Planarian
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive properties of their mucus. They lack water-retaining mechanisms and are therefore very sensitive to humidity variations of their environment. Because of their strict ecological requirements, some species have been proposed as indicators of the conservation state of their habitats. They are generally animals with low vagility (dispersal ability) and with very specific habitat requirements, so they can be also used to accurately determine the distribution of biogeographic realms. Today the fauna of these animals is being studied to select conservation priorities in the Atlantic rainforest in Brazil. At the other extreme, one species in this family, '' Platydemus manokwari'' has become an invasive species in both disturbed and wild habitats in the ...

Geoplaninae
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region. Members of this family are sometimes referred to as the Neotropical land planarians. However, one species, '' Obama nungara'' has been introduced in Europe. Description The subfamily Geoplaninae was initially defined by Ogren and Kawakatsu (1990)Ogren, R. E. and Kawakatsu, M. (1990).

Cananéia
Cananéia is the southernmost city in the state of São Paulo, Brazil, near where the Tordesilhas Line passed. The population in 2020 was 12,541 and its area is 1,242.010 km². The elevation is 8 m. The city of Cananéia is host to the Dr. João de Paiva Carvalho research base belonging to the Oceanographic Institute of the University of São Paulo. Cananéia is considered by some Portuguese and Spanish historians to be the oldest city in Brazil, five months before the founding of São Vicente, but due to the lack of official documentation proving this fact, São Vicente is officially the oldest city in Brazil. The Historic Center of Cananéia, listed by CONDEPHAAT, still preserves the architectural styles adopted by the first houses and churches from the colonial period until the end of the 19th century. The beaches also attract thousands of people in high season, and Ilha do Cardoso has several trails and waterfalls, as well as several archaeological sites. Festivals, ...

Stroma (tissue)
Stroma () is the part of a tissue (biology), tissue or organ (anatomy), organ with a structural or connective role. It is made up of all the parts without specific functions of the organ - for example, connective tissue, blood vessels, ducts, etc. The other part, the parenchyma, consists of the cells that perform the function of the tissue or organ. There are multiple ways of classifying tissues: one classification scheme is based on tissue functions and another analyzes their cellular components. Stromal tissue falls into the "functional" class that contributes to the body's support and movement. Stromal cell, The cells which make up stroma tissues serve as a matrix in which the other cells are embedded. Stroma is made of various types of stromal cells. Examples of stroma include: * stroma of iris * stroma of cornea * stroma of ovary * stroma of thyroid gland * stroma of thymus * stroma of bone marrow * lymph node stromal cell *Mesenchymal stem cell, multipotent stromal cell (me ...

Animals Described In 2019
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (). With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology, and the study of animal behaviour is known as ethology. The animal kingdom is divided into five major clades, namely Porifera, Ctenophora, Placozoa, C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
