The short-beaked common dolphin is a species of common dolphin. It has a larger range than the long-beaked common dolphin, occurring throughout warm-temperate and tropical oceans, including the Indian Ocean although in smaller numbers than other places they are found. There are more short-beaked common dolphins than any other dolphin species in the warm-temperate portions of the Atlantic and Pacific Oceans. It is also found in the Caribbean and Mediterranean Seas. The short-beaked common dolphin is also abundant in the Black Sea, Gulf of Mexico, and Red Sea. They follow the gulf stream up to Norwegian waters. Seldom do any short-beaked dolphin venture near the Arctic.
Kelp forests are under water areas with a high density of kelp, which covers a large part of the world's coastlines. They are recognized as one of the most productive and dynamic ecosystems on Earth. Smaller areas of anchored kelp are called kelp beds. Kelp forests occur worldwide throughout temperate and polar coastal oceans. In 2007, kelp forests were also discovered in tropical waters near Ecuador. In context, algal kelp forest combined with coral reefs account for less than 1% of global primary productivity.
The butterfly rays are the rays forming the genus Gymnura and the family Gymnuridae. They are found in warm oceans worldwide, and occasionally in estuaries.
The Amazonian sac-winged bat is a bat species of the family Emballonuridae from South America. It is found in northern Brazil, Guyana, French Guiana, Suriname and possibly Venezuela.
The longfin catshark is a catshark of the family Scyliorhinidae found in the western Pacific from Japan to the Philippines, and the East and South China Seas, and the Kyūshū-Palau Ridge, at depths between 530 and 865 m. Its length is up to 48 cm.
The broadmouth catshark is a rare catshark of the family Scyliorhinidae, the holotype and only specimen of which was taken from off Zhujiang in the South China Sea, at a depth of 913 m. Its length is around 38 cm. The broadmouth catshark's reproduction is oviparous. Considering the species is not well known, the threats are not known either but may be deepwater fisheries.
Saccopteryx is a genus of sac-winged bats from Central and South America. The species within this genus are:
The moonrat is a southeast Asian species of mammal in the family Erinaceidae. It is the only species in the genus Echinosorex. The moonrat is a fairly small, primarily carnivorous animal which, despite its name, is not closely related to rats or other rodents. The scientific name is sometimes given as Echinosorex gymnurus, but this is incorrect.
The Ontong Java flying fox is a species of flying fox in the family Pteropodidae. It is endemic to the Ontong Java Atoll in the Solomon Islands. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical swamps. It was classified as "Critically Endangered" in 2021 by the IUCN. Its confirmed range extends only over small islands, all of which are near to sea level. It is threatened by rising sea levels.
The California butterfly ray is a species of ray in the family Gymnuridae. It is found in Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Peru, and the United States. Its natural habitats are shallow seas, subtidal aquatic beds, coral reefs, estuarine waters, intertidal marshes, and coastal saline lagoons.
The smooth butterfly ray is a species of cartilaginous fish in the family Gymnuridae. It is a member of the order Myliobatiformes, which contains 10 total families. Its natural habitats are shallow seas, subtidal aquatic beds, estuarine waters, and coastal saline lagoons. Its common name is derived from its compressed body, pectoral fins that are wider than their length, and overall diamond shape.
The backwater butterfly ray, butterfly ray, diamond ray, or short-tailed ray is a species of fish in the family Gymnuridae. It is found in Mozambique, Namibia, South Africa, possibly Kenya, and possibly Tanzania. Its natural habitats are open seas, shallow seas, estuarine waters, and coastal saline lagoons. It is threatened by habitat loss. It was considered common from 1940s-1960s.
The longtail butterfly ray is a species of butterfly ray, family Gymnuridae, native to the Indo-Pacific from the Red Sea to southern Japan and western Indonesia. Growing up to 92 cm (36 in) across, this ray has a lozenge-shaped pectoral fin disc about twice as wide as long, colored brown to gray above with many small, light spots. The spiracles behind its eyes have smooth rims. This species can be identified by its tail, which is about as long as the snout-to-vent distance, lacks fins, and bears nine to twelve each of alternating black and white bands.
The porcupine ray is a rare species of stingray in the family Dasyatidae. This bottom-dweller is found throughout the tropical Indo-Pacific, as well as off West Africa. It favors sand, coral rubble, and seagrass habitats in inshore waters to a depth of 30 m (100 ft). A large and heavy-bodied species reaching 1.2–1.5 m (3.9–4.9 ft) in width, the porcupine ray has a nearly circular, plain-colored pectoral fin disc and a thin tail without any fin folds. Uniquely within its family, it lacks a venomous stinging spine. However, an adult ray can still defend itself ably with the many large, sharp thorns found over its disc and tail.
Tide gauge measurements show that global sea level rise began around the start of the 20th century. Between 1900 and 2016, the globally averaged sea level rose by 16–21 cm (6.3–8.3 in). More precise data gathered from satellite radar measurements reveal an accelerating rise of 7.5 cm (3.0 in) from 1993 to 2017, which is a trend of roughly 30 cm (12 in) per century. This acceleration is due mostly to human-caused global warming, which is driving thermal expansion of seawater and the melting of land-based ice sheets and glaciers. Between 1993 and 2018, thermal expansion of the oceans contributed 42% to sea level rise; the melting of temperate glaciers, 21%; Greenland, 15%; and Antarctica, 8%. Climate scientists expect the rate to further accelerate during the 21st century, with the latest statistics saying the sea levels are rising by 3.6mm per year.
The spiny butterfly ray or giant butterfly ray is a species of butterfly ray, family Gymnuridae, native to the shallow coastal waters of the Atlantic Ocean. A large ray that can measure over 2 m across, it may be distinguished from the sympatric smooth butterfly ray by the spine at the base of its tail and by a small tentacular structure on the margin of each spiracle. Slow-reproducing and valued for its meat, in recent decades its population has experienced a decline of over 30%, and it has become Critically Endangered in certain parts of its range.
The Japanese butterfly ray is a species of ray in the family Gymnuridae. It is found from Japan to Cambodia.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), has many variants; some are believed or have been believed to be of particular importance due to their potential for increased transmissibility, increased virulence, and reduced effectiveness of vaccines against them. This article discusses such notable variants of SARS-CoV-2 and notable missense mutations found in these variants.
The Ethiopian ridgeback agama , is a species of lizard in the family Agamidae. The species is endemic to the Horn of Africa. It is among the largest species of Xenagama, with snout-to-vent length of males up to 84.5mm.
