Raddaus is a genus of crabs in the family Pseudothelphusidae, containing the following species: [1]
The Chaetognatha or chaetognaths are a phylum of predatory marine worms that are a major component of plankton worldwide. Commonly known as arrow worms, about 20% of the known Chaetognatha species are benthic, and can attach to algae and rocks. They are found in all marine waters, from surface tropical waters and shallow tide pools to the deep sea and polar regions. Most chaetognaths are transparent and are torpedo shaped, but some deep-sea species are orange. They range in size from 2 to 120 millimetres.
Guava is a common tropical fruit cultivated in many tropical and subtropical regions. Psidium guajava is a small tree in the myrtle family (Myrtaceae), native to Mexico, Central America, the Caribbean and northern South America. Although related species may also be called guavas, they belong to other species or genera, such as the pineapple guava, Feijoa sellowiana. In 2019, 55 million tonnes of guavas were produced worldwide, led by India with 45% of the total.
The Decapoda or decapods are an order of crustaceans within the class Malacostraca, including many familiar groups, such as crayfish, crabs, lobsters, prawns, and shrimp. Most decapods are scavengers. The order is estimated to contain nearly 15,000 species in around 2,700 genera, with around 3,300 fossil species. Nearly half of these species are crabs, with the shrimp and Anomura including hermit crabs, porcelain crabs, squat lobsters making up the bulk of the remainder. The earliest fossil decapod is the Devonian Palaeopalaemon.
Endemism is the state of a species being native to a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is exclusively found in southwestern South Africa and is therefore said to be endemic to that particular part of the world. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range.
The whistling ducks or tree ducks are a subfamily, Dendrocygninae, of the duck, goose and swan family of birds, Anatidae. They are not true ducks. In other taxonomic schemes, they are considered a separate family, Dendrocygnidae. Some taxonomists list only one genus, Dendrocygna, which contains eight living species, and one undescribed extinct species from Aitutaki of the Cook Islands, but other taxonomists also list the white-backed duck under the subfamily.
Ectobiidae is a family of the order Blattodea (cockroaches). This family contains many of the smaller common household pest cockroaches, among others. They are sometimes called wood cockroaches. A few notable species include:
Strombus is a genus of medium to large sea snails, marine gastropod molluscs in the family Strombidae, which comprises the true conchs and their immediate relatives. The genus Strombus was named by Swedish Naturalist Carl Linnaeus in 1758. Around 50 living species were recognized, which vary in size from fairly small to very large. Six species live in the greater Caribbean region, including the queen conch, Strombus gigas, and the West Indian fighting conch, Strombus pugilis. However, since 2006, many species have been assigned to discrete genera. These new genera are, however, not yet found in most textbooks and collector's guides.
Pyramidellidae, common name the pyram family, or pyramid shells, is a voluminous taxonomic family of mostly small and minute ectoparasitic sea snails, marine heterobranch gastropod molluscs. The great majority of species of pyrams are micromolluscs.
Palaeoheterodonta is a subclass of bivalve molluscs. It contains the extant orders Unionida and Trigoniida. They are distinguished by having the two halves of the shell be of equal size and shape, but by having the hinge teeth be in a single row, rather than separated into two groups, as they are in the clams and cockles.
The Buccinidae are a very large and diverse taxonomic family of large sea snails, often known as whelks or true whelks.
Pseudothelphusidae is a family of freshwater crabs found chiefly in mountain streams in the Neotropics. They are believed to have originated in the Greater Antilles and then crossed to Central America via a Pliocene land bridge.
Deltasaurus is an extinct genus of Carnian temnospondyl amphibian of the family Rhytidosteidae.
Hastula is a genus of sea snails, marine gastropod mollusks in the family Terebridae, the auger snails.
Agladrillia is a genus of sea snails, marine gastropod mollusks in the family Drilliidae.
Murexiella is a genus of sea snails, marine gastropod mollusks in the family Muricidae, the murex snails or rock snails.
Olivancillaria is a genus of sea snails, marine gastropod mollusks in the family Olividae.
Trophoninae is a subfamily of predatory sea snails, marine gastropod mollusks in the family Muricidae, the rock snails and their allies.
Oradectes is an extinct genus of diadectid reptiliomorph. It is known from a single partial skeleton collected from the Early Permian Cutler Formation of Colorado in the United States. The type species, O. sanmiguelensis, was originally named as a species of Diadectes in 1965. It was given its own genus in 2010.
Williams' mud turtle is a species of turtle in the family Pelomedusidae. The species is endemic to Africa.
