Plica rayi, Ray's treerunner, is a species of South American lizard in the family Tropiduridae. The species is found in Colombia and Venezuela. [1]
The Tropiduridae are a family of iguanid lizards. The family is sometimes considered a subfamily, Tropidurinae. The subfamily is native to South America, including the islands of Trinidad and the Galápagos. Commonly known as neotropical ground lizards, most are ground-dwelling animals, and the subfamily includes some lizards adapted to relatively cold climates, including those of the Andes mountains and Tierra del Fuego. Several species give birth to live young.
Plica is a genus of tropidurid lizards found in South America and the Caribbean. Species in the genus Plica are arboreal, medium-sized lizards.
The nictitating membrane is a transparent or translucent third eyelid present in some animals that can be drawn across the eye from the medial canthus to protect and moisten it while maintaining vision. All Anura(tailless amphibians), and some reptiles, birds, sharks have full nictitating membranes; in many mammals, a small, vestigial portion of the nictitating membrane remains in the corner of the eye. Some mammals, such as cats, camels, polar bears, seals and aardvarks, have full nictitating membranes. Often called a third eyelid or haw, it may be referred to in scientific terminology as the plica semilunaris, membrana nictitans, or palpebra tertia.
The plica semilunaris is a small fold of bulbar conjunctiva on the medial canthus of the eye. It functions during movement of the eye, to help maintain tear drainage via the lacrimal lake, and to permit greater rotation of the globe, for without the plica the conjunctiva would attach directly to the eyeball, restricting movement. It is the vestigial remnant of the nictitating membrane which is drawn across the eye for protection, and is present in other animals such as birds, reptiles, and fish, but is rare in mammals, mainly found in monotremes and marsupials. Its associated muscles are also vestigial. It is loose, thus eye movements are not restricted by it. Only one species of primate, the Calabar angwantibo, is known to have a functioning nictitating membrane.
Plasmodium guyannense is a parasite of the genus Plasmodium subgenus Sauramoeba. As in all Plasmodium species, P. guyannense has both vertebrate and insect hosts. The vertebrate hosts for this parasite are reptiles.
Plasmodium vacuolatum is a parasite of the genus Plasmodium.
Plasmodium audaciosum is a parasite of the genus Plasmodium.
Simocetus is an extinct genus of toothed whale that lived during the Oligocene period, approximately 32 million years ago, making it the oldest named toothed whale, although older unnamed toothed whales exist.
Capillaria plica is a parasitic nematode which is most often found in the urinary bladder, and occasionally in the kidneys, of dogs and foxes. It has also been found in the domestic cat, and various wild mammals. Its presence usually produces no clinical symptoms, but in some cases, it leads to hematuria, cystitis, or difficulty in urination.
In the 10th edition of Systema Naturae, Carl Linnaeus described the Amphibia as:
Animals that are distinguished by a body cold and generally naked; stern and expressive countenance; harsh voice; mostly lurid color; filthy odor; a few are furnished with a horrid poison; all have cartilaginous bones, slow circulation, exquisite sight and hearing, large pulmonary vessels, lobate liver, oblong thick stomach, and cystic, hepatic, and pancreatic ducts: they are deficient in diaphragm, do not transpire (sweat), can live a long time without food, are tenatious of life, and have the power of reproducing parts which have been destroyed or lost; some undergo a metamorphosis; some cast (shed) their skin; some appear to live promiscuously on land or in the water, and some are torpid during the winter.
The Reptile Database is a scientific database that collects taxonomic information on all living reptile species. The database focuses on species and has entries for all currently recognized ~13,000 species and their subspecies, although there is usually a lag time of up to a few months before newly described species become available online. The database collects scientific and common names, synonyms, literature references, distribution information, type information, etymology, and other taxonomically relevant information.
Plica plica is a species of lizard in the family Tropiduridae, the Neotropical ground lizards. Its common names include collared tree lizard, collared tree runner,tree runner, and harlequin racerunner. In Guyana it is known as wakanama.
Bandringa is an extinct genus of Elasmobranch known from the Pennsylvanian subperiod of the Carboniferous period that was part of the monotypic family Bandringidae. There is currently a single known species, B. rayi, described in 1969. It is known from exceptionally preserved individuals found in the Mazon Creek Lagerstätte of Illinois which dates back to the late Moscovian stage; the holotype, a juvenile, was found by Ray Bandringa in an ironstone concretion during the summer of 1967. Two species from this genus were originally described, B. rayi and B. herdinae, but the differences between the two were found to be taphonomic in origin. All Mazon Creek individuals appear to represent juveniles, suggesting the area was a nursery for them. Also supporting this notion are fossilized egg cases found in the same localities, though it is unclear whether they belong to this genus. Adult fossils attributed to B. rayi have also been found in spoil heaps from Five Points coal mines near Conesville, Ohio and Cannelton, Pennsylvania, both of which contain the roughly contemporaneous Kittaning Formation of the Allegheny Group. This species has a long rostrum and may have been analogous to modern sawfish. It appears to have fed via suction feeding. Preserved gut contents include articulated arthropods. Estimated from the juvenile fossils and partial adult fossils, the adult is close to 70 cm (28 in). Its relationships to other elasmobranchs is currently unclear.
