Toxungen
A toxungen comprises a secretion or other bodily fluid containing one or more biological toxins that is transferred by one animal to the external surface of another animal via a physical delivery mechanism with or without direct contact between the secreting animal and the victim. Toxungens can be delivered through spitting, spraying, or smearing. As one of three categories of biological toxins, toxungens can be distinguished from poisons, which are passively transferred via ingestion, inhalation, or absorption across the skin, and venoms, which are delivered through a wound generated by direct contact in the form of a bite, sting, or other such action. Toxungen use offers the evolutionary advantage of delivering toxins into the target's tissues without the need for physical contact. Animals that deploy toxungens are referred to as ''toxungenous''. Taxonomic distribution Toxungens have evolved in a variety of animals, including flatworms, insects, arachnids, cephalopods, amphibian ...

Slow Loris
Slow lorises are a group of several species of Nocturnality, nocturnal Strepsirrhini, strepsirrhine primates that make up the genus ''Nycticebus''. Found in Southeast Asia and nearby areas, they range from Bangladesh and Northeast India in the west to the Sulu Archipelago in the Philippines in the east, and from Yunnan province in China in the north to the island of Java in the south. Although many previous classifications recognized as few as a single all-inclusive species, there are now at least eight that are considered valid: the Sunda slow loris (''N. coucang''), Bengal slow loris (''N. bengalensis''), Javan slow loris (''N. javanicus''), Philippine slow loris (''N. menagensis''), Bangka slow loris (''N. bancanus''), Bornean slow loris (''N. borneanus''), Kayan River slow loris (''N. kayan'') and Sumatran slow loris (''N. hilleri''). A ninth species, the pygmy slow loris (''X. pygmaeus''), was recently moved to the new genus ''Xant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue-ringed Octopus
Blue-ringed octopuses, comprising the genus ''Hapalochlaena'', are four extremely venomous species of octopus that are found in tide pools and coral reefs in the Pacific and Indian Oceans, from Japan to Australia. They can be identified by their yellowish skin and characteristic blue and black rings that can change color dramatically when the animals are threatened. They eat small crustaceans, including crabs, hermit crabs, shrimp, and other small sea animals. They are some of the world's most venomous marine animals. Despite their small size——and relatively docile nature, they are very dangerous if provoked when handled because their venom contains a powerful neurotoxin called tetrodotoxin. The species tends to have a lifespan around two to three years, which may vary depending on factors such as nutrition, temperature, and the intensity of light within its environment. Classification The genus was described by British zoologist Guy Coburn Robson in 1929. Four specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firefly
The Lampyridae are a family of elateroid beetles with more than 2,000 described species, many of which are light-emitting. They are soft-bodied beetles commonly called fireflies, lightning bugs, or glowworms for their conspicuous production of light, mainly during twilight, to attract mates. The type species is '' Lampyris noctiluca'', the common glow-worm of Europe. Light production in the Lampyridae is thought to have originated as a warning signal that the larvae were distasteful. This ability to create light was then co-opted as a mating signal and, in a further development, adult female fireflies of the genus '' Photuris'' mimic the flash pattern of the '' Photinus'' beetle to trap their males as prey. Fireflies are found in temperate and tropical climates. Many live in marshes or in wet, wooded areas where their larvae have abundant sources of food. Although all known fireflies glow as larvae, only some species produce light in their adult stage, and the location ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toad
Toad (also known as a hoptoad) is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands. In popular culture (folk taxonomy), toads are distinguished from frogs by their drier, rougher skin and association with more terrestrial habitats. However, this distinction does not align precisely with scientific taxonomy. List of toad families In scientific taxonomy, toads include the true toads (Bufonidae) and various other terrestrial or warty-skinned frogs. Non-bufonid "toads" can be found in the families: * Bombinatoridae ( fire-bellied toads and jungle toads) * Calyptocephalellidae ( helmeted water toad and false toads) * Discoglossidae ( midwife toads) * Myobatrachidae (Australian toadlets) * Pelobatidae ( European spadefoot toad) * Rhinophrynidae ( burrowing toads) * Scaphiopodidae ( American spadefoot toads) * Microhylidae ( narrowmouth toads) ...

Rhabdophis
''Rhabdophis'' is a genus of snakes in the subfamily Natricinae of the family Colubridae. Species in the genus ''Rhabdophis'' are generally called keelback snakes, and are found primarily in Southeast Asia. The best-known species is '' Rhabdophis tigrinus''; few other species have been studied in detail. Toxicity Colubrid snakes are often thought of as completely harmless, but there are a handful of notable exceptions, including some species of ''Rhabdophis''. Bites from both ''Rhabdophis tigrinus'' and ''Rhabdophis subminiatus'' have caused cases of severe envenomation. There are several reports of fatal bites from ''R. tigrinus''. Between 1971 and 2020, 5 of 43 ''R. tigrinus'' bites in Japan were fatal, all of which occurred in cases not treated with antivenom. Antivenom is manufactured by the Japan Snake Institute and is an effective treatment for ''R. tigrinus'' bites, but is an unapproved drug. The venom is highly hemorrhagic.

Parabuthus Transvaalicus
''Parabuthus transvaalicus'' (known as the Transvaalicus thick-tailed scorpion, South African thick tail, or giant deathstalker) is a species of venomous scorpion from semi-arid parts of southern Africa. Description ''Parabuthus transvaalicus'' grows to a length of , and is dark brown or black in colour, so it is also known as the Black Thick-Tailed scorpion. Its pincers are thin, but its tail is thickened, with the sting segment being as wide as the rest of the tail. It is nocturnal, resting in a shallow burrow under rocks during the day.

Dilophosaurus
''Dilophosaurus'' ( ) is a genus of theropod dinosaurs that lived in what is now North America during the Early Jurassic, about 186 million years ago. Three skeletons were discovered in northern Arizona in 1940, and the two best preserved were collected in 1942. The most complete specimen became the holotype of a new species in the genus ''Megalosaurus'', named ''M. wetherilli'' by Samuel P. Welles in 1954. Welles found a larger skeleton belonging to the same species in 1964. Realizing it bore crests on its skull, he assigned the species to the new genus ''Dilophosaurus'' in 1970, as ''Dilophosaurus wetherilli''. The genus name means "two-crested lizard", and the species name honors John Wetherill, a Navajo councilor. Further specimens have since been found, including an infant. Fossil footprints have also been attributed to the animal, including resting traces. Another species, ''Dilophosaurus sinensis'' from China, was named in 1993, but was later found to belon ...

Mustelidae
The Mustelidae (; from Latin , weasel) are a diverse family of carnivora, carnivoran mammals, including weasels, badgers, otters, polecats, martens, grisons, and wolverines. Otherwise known as mustelids (), they form the largest family in the suborder Caniformia of the order (biology), order Carnivora with about 66 to 70 species in nine subfamilies. Variety Mustelids vary greatly in size and behaviour. The smaller variants of the least weasel can be under in length, while the giant otter of Amazon rainforest, Amazonian South America can measure up to and sea otters can exceed in weight. Wolverines can crush bones as thick as the femur of a moose to get at the Bone marrow, marrow, and have been seen attempting to drive bears away from their kills. The sea otter uses rocks to break open shellfish to eat. Martens are largely arboreal, while European badgers dig extensive tunnel networks, called setts. Only one mustelid has been domesticated; the ferret. Tayra are also kept ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
