Bryozoa are a phylum of aquatic invertebrate animals, nearly all forming sedentary colonies. Typically about 0.5 millimetres long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia. Most marine species live in tropical waters, but a few occur in oceanic trenches, and others are found in polar waters. One class lives only in freshwater environments, and a few members of a mostly marine class prefer brackish water. 5869 living species are known. One genus is solitary and the rest are colonial.
Internal transcribed spacer (ITS) is the spacer DNA situated between the small-subunit ribosomal RNA (rRNA) and large-subunit rRNA genes in the chromosome or the corresponding transcribed region in the polycistronic rRNA precursor transcript.
The Nilgiri langur is a langur found in the Nilgiri Hills of the Western Ghats in South India. Its range also includes Kodagu in Karnataka, Kodayar Hills in Tamil Nadu, and many other hilly areas in Kerala and Tamil Nadu. This primate has glossy black fur on its body and golden brown fur on its head. It is similar in size and long-tailed like the gray langurs. Females have a white patch of fur on the inner thigh. It typically lives in troops of nine to ten monkeys. Its diet consists of fruits, shoots and leaves. The species is classified as vulnerable due to habitat destruction and poaching for its fur and flesh, the latter believed to have aphrodisiac properties.
Dicraeosauridae is a family of diplodocoid sauropods who are the sister group to Diplodocidae. Dicraesaurids are a part of the Flagellicaudata, along with Diplodocidae. Dicraeosauridae includes genera such as Amargasaurus, Suuwassea, Dicraeosaurus, and Brachytrachelopan. Specimens of this family have been found in North America, Asia, Africa, and South America. Their temporal range is from the Early or Middle Jurassic to the Early Cretaceous. Few dicraeosaurids survived into the Cretaceous, the youngest of which was Amargasaurus.
The Halisaurinae are a subfamily of mosasaurs, a diverse group of Late Cretaceous marine squamates. Members of the subfamily are informally and collectively known as "halisaurines" and have been recovered from North and South America, Europe, Asia and Africa, indicating a more or less global distribution in the Late Cretaceous. Though all the genera included in the subfamily have at one point or another been included within Halisaurus, the genera currently seen as valid halisaurines are Eonatator, Halisaurus, Phosphorosaurus and Pluridens.
In phylogenetics, basal is the direction of the base of a rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Each node in the tree corresponds to a clade; i.e., clade C may be described as basal within a larger clade D if its root is directly linked to the root of D. The terms deep-branching or early-branching are similar in meaning.
Strombus pugilis, common names the fighting conch and the West Indian fighting conch, is a species of medium to large sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs.
Lobatus raninus, common name the hawk-wing conch, is a species of medium to large sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs.
Strombus alatus, the Florida fighting conch, is a species of medium-sized, warm-water sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs.
Lobatus goliath, previously known as Eustrombus goliath and Strombus goliath, common name the goliath conch, is a species of very large edible sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs. L. goliath is one of the largest mollusks of the Western Atlantic Ocean, and also one of the largest species among the Strombidae. It was once considered endemic to Brazil, but specimens have also been recently found in the waters of Barbados. Brazilian common names for this species include búzio de chapéu or búzio, and búzio de aba or buzo in. L. goliath is considered closely related to the queen conch, Lobatus gigas.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 2014.
Onchidoris proxima is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusc in the family Onchidorididae. This species is found in the northeastern and northwestern parts of the Atlantic Ocean. It is also reported from the northeastern Pacific Ocean. Previously in the genus Adalaria this species was moved to Onchidoris as a result of a molecular phylogeny study.
