Aztecacris laevis is a species of spur-throated grasshopper in the family Acrididae. It is found in Mexico. [1] [2]
The African clawed frog, also known as simply Xenopus, African clawed toad, African claw-toed frog or the Platanna) is a species of African aquatic frog of the family Pipidae. Its name is derived from the short black claws on its feet. The word Xenopus means 'strange foot' and laevis means 'smooth'.
Amelanchier, also known as shadbush, shadwood or shadblow, serviceberry or sarvisberry, juneberry, saskatoon, sugarplum, wild-plum or chuckley pear, is a genus of about 20 species of deciduous-leaved shrubs and small trees in the rose family (Rosaceae).
Ulmus laevisPall., variously known as the European white elm, fluttering elm, spreading elm, stately elm and, in the United States, the Russian elm, is a large deciduous tree native to Europe, from France northeast to southern Finland, east beyond the Urals into Kyrgyzstan and Kazakhstan, and southeast to Bulgaria and the Crimea; there are also disjunct populations in the Caucasus and Spain, the latter now considered a relict population rather than an introduction by man, and possibly the origin of the European population. U. laevis is rare in the UK, although its random distribution, together with the absence of any record of its introduction, has led at least one British authority to consider it native. NB: The epithet 'white' elm commonly used by British foresters alluded to the timber of the wych elm.
Zanclodon is an extinct genus of archosauriform from the Erfurt Formation in southern Germany. It was once a wastebasket taxon until a taxonomic revision by Schoch (2011) left only the paratype within Zanclodon laevis proper. The type species is Z. laevis.
Frogs have been used in animal tests throughout the history of biomedical science.
The barndoor skate is a species of marine cartilaginous fish in the skate family Rajidae of the order Rajiformes. It is native to the northwestern Atlantic Ocean, and is found from the Grand Banks of Newfoundland and the southern side of the Gulf of St. Lawrence south to North Carolina. The fish is one of the largest skates found in the North Atlantic Ocean, reaching lengths up to 1.5 m (5 ft). It is carnivorous, feeding on invertebrates and other fish found near the sea floor.
The European White Elm cultivar Ulmus laevis 'Colorans' was listed as U. effusa var. colorans by Kirchner in Petzold & Kirchner, Arboretum Muscaviense (1864).
Ulmus laevis var. celtideaRogow. is a putative variety of European White Elm first described by Rogowicz, who found the tree in 1856 along the river Dnjepr near Chernihiv in what is now northern Ukraine. The type specimen is held at the National Herbarium of Ukraine. The variety was first named as Ulmus pedunculata var. celtidea. Litvinov (1908) considered it a species, calling it Ulmus celtideaLitv., a view not upheld by other authorities.
Pomphorhynchus laevis is an endo-parasitic acanthocephalan worm, with a complex life cycle, that can modify the behaviour of its intermediate host, the freshwater amphipod Gammarus pulex. P. laevis does not contain a digestive tract and relies on the nutrients provided by its host species. In the fish host this can lead to the accumulation of lead in P. laevis by feeding on the bile of the host species.
Nectophrynoides laevis, the smooth forest toad, is a species of toad in the family Bufonidae.
Lepidobatrachus laevis, widely known as Budgett's frog, is a species of frog in the family Ceratophryidae, discovered by John Samuel Budgett. It is often kept as a pet. It has acquired a number of popular nicknames, including hippo frog, Freddy Krueger frog, and escuerzo de agua.
Rhynchobatus is a group of rays commonly known as wedgefishes in the family Rhinidae. They are found in the tropical and subtropical Indo-Pacific with a single species in the eastern Atlantic. All species in this genus are assessed as Vulnerable or Endangered by IUCN.
Porcellio laevis is a species of woodlouse in the genus Porcellio. As the species epithet laevis as well as the vernacular name "swift woodlouse" suggests, the species is capable of quick bursts of speed when provoked.
The western clawed frog is a species of frog in the family Pipidae, also known as tropical clawed frog. It is the only species in the genus Xenopus to have a diploid genome. Its genome has been sequenced, making it a significant model organism for genetics that complements the related species Xenopus laevis, a widely used vertebrate model for developmental biology. X. tropicalis also has a number of advantages over X. laevis in research, such as a much shorter generation time, smaller size, and a larger number of eggs per spawn.
Amelanchier laevis, the smooth shadbush, smooth serviceberry or Allegheny serviceberry, is a North American species of tree in the rose family Rosaceae, growing up to 9 metres (30 ft) tall. It is native to eastern Canada and the eastern United States, from Newfoundland west to Ontario, Minnesota, and Iowa, south as far as Georgia and Alabama.
Plectropomus laevis, known commonly as the black-saddled coral grouper, cluespotted coral trout, blacksaddled coral trout, blue-spot trout, Chinese footballer, footballer cod, footballer coral trout, oceanic coral trout or tiger trout, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the Indo-Pacific region.
Mirosternus laevis is a species of beetle in the family Ptinidae.
Ulmus laevis var. parvifolia is a mutant variety of European white elm found exclusively on the island of Ada Ciganlija, in the Sava at Belgrade, Serbia.
Opisthopatus laevis is a species of velvet worm in the Peripatopsidae family. This species has 16 pairs of legs. The type locality is in South Africa. The validity of this species is uncertain: Some authorities consider O. laevis invalid even as a subspecies of O. cinctipes, a similar species also found in South Africa, but other authorities recognize O. laevis as a separate species, citing the significant distance (570 km) between the type localities of these two species.
Aztecacris gloriosa, the atascosa gem grasshopper, is a species of spur-throated grasshopper in the family Acrididae. It is found in the southwestern United States and Mexico.
