H. R. Giger Swiss artist

Hans Ruedi Giger was a Swiss artist best known for his airbrushed images that blended human physiques with machines, an art style known as "biomechanical". Giger later abandoned airbrush for pastels, markers and ink. He was part of the special effects team that won an Academy Award for the visual design of Ridley Scott's 1979 sci-fi horror film Alien. His work is on permanent display at the H.R. Giger Museum in Gruyères, Switzerland. His style has been adapted to many forms of media, including album covers, furniture, and tattoos.

Invertebrate Animals without a vertebrate column

Invertebrates are animals that neither possess nor develop a vertebral column, derived from the notochord. This includes all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelid, and cnidarians.

Largemouth bass Species of black bass

The largemouth bass is a carnivorous freshwater gamefish in the Centrarchidae (sunfish) family, a species of black bass native to the eastern and central United States, southeastern Canada and northern Mexico, but widely introduced elsewhere. It is known by a variety of regional names, such as the widemouth bass, bigmouth bass, black bass, bucketmouth, largies, Potter's fish, Florida bass, Florida largemouth, green bass, bucketmouth bass, Green trout, gilsdorf bass, Oswego bass, LMB, and southern largemouth and northern largemouth. The largemouth bass is the state fish of Georgia and Mississippi, and the state freshwater fish of Florida and Alabama.

Firefly Family of beetles

The Lampyridae are a family of insects in the beetle order Coleoptera, with more than 2,000 described species, many of which are light-emitting. They are soft-bodied beetles commonly called fireflies, glowworms, or lightning bugs for their conspicuous production of light, mainly during twilight, to attract mates. Light production in the Lampyridae originated as an honest warning signal that the larvae were distasteful; this was co-opted in evolution as a mating signal in the adults. In a further development, female fireflies of the genus Photuris mimic the flash pattern of Photinus species to trap their males as prey.

King Ghidorah Fictional character/Kaiju

King Ghidorah is a fictional monster, or kaiju, which first appeared in Ishirō Honda's 1964 film Ghidorah, the Three-Headed Monster. Although the name of the character is officially trademarked by Toho as "King Ghidorah", the character was originally referred to as Ghidorah or Ghidrah in some English markets.

North Sulawesi babirusa Species of mammal

The North Sulawesi babirusa is a pig-like animal native to Sulawesi and some nearby islands in Indonesia. It has two pairs of large tusks composed of enlarged canine teeth. The upper canines penetrate the top of the snout, curving back toward the forehead. The North Sulawesi babirusa is threatened from hunting and deforestation.

<i>Glycera</i> (annelid) Genus of annelid worms

The genus Glycera is a group of polychaetes commonly known as bloodworms. They are typically found on the bottom of shallow marine waters, and some species can grow up to 35 centimetres (14 in) in length.

Planarian Flatworms of the Turbellaria class

A planarian is one of many flatworms of the traditional class Turbellaria. It usually describes free-living flatworms of the order Tricladida (triclads), although this common name is also used for a wide number of free-living platyhelminthes. Planaria are common to many parts of the world, living in both saltwater and freshwater ponds and rivers. Some species are terrestrial and are found under logs, in or on the soil, and on plants in humid areas.

Molidae Family of fishes

The Molidae comprise the family of the molas or ocean sunfishes, unusual fish whose bodies come to an end just behind the dorsal and anal fins, giving them a "half-fish" appearance. They are also the largest of the ray-finned bony fish, with the ocean sunfish Mola mola and southern sunfish, Mola alexandrini, both recorded at up to 4.6 m (15 ft) in length and 2,300 kg (5,100 lb) in weight.

<i>Diphyllobothrium</i> Genus of flatworms

Diphyllobothrium is a genus of tapeworms which can cause diphyllobothriasis in humans through consumption of raw or undercooked fish. The principal species causing diphyllobothriasis is D. latum, known as the broad or fish tapeworm, or broad fish tapeworm. D. latum is a pseudophyllid cestode that infects fish and mammals. D. latum is native to Scandinavia, western Russia, and the Baltics, though it is now also present in North America, especially the Pacific Northwest. In Far East Russia, D. klebanovskii, having Pacific salmon as its second intermediate host, was identified.

Peterss elephantnose fish Species of fish

Peters's elephant-nose fish is an African freshwater elephantfish in the genus Gnathonemus. Other names in English include elephantnose fish, long-nosed elephant fish, and Ubangi mormyrid, after the Ubangi River. The Latin name petersii confirms it is named after someone called "Peters", although the apostrophe is often misplaced and the common name given as "Peter's elephantnose fish". It uses electrolocation to find prey, and has the largest brain-to-body oxygen use ratio of all known vertebrates.

Nematode Phylum of worms with tubular digestive systems with openings at both ends

The nematodes or roundworms constitute the phylum Nematoda, with plant-parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Taxonomically, they are classified along with insects and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum.

<i>Serpula</i> Genus of annelid worms

Serpula is a genus of sessile, marine annelid tube worms that belongs to the family Serpulidae. Serpulid worms are very similar to tube worms of the closely related sabellid family, except that the former possess a cartilaginous operculum that occludes the entrance to their protective tube after the animal has withdrawn into it. The most distinctive feature of worms of the genus Serpula is their colorful fan-shaped "crown". The crown, used by these animals for respiration and alimentation, is the structure that is most commonly seen by scuba divers and other casual observers.

<i>Peripatopsis capensis</i> Species of velvet worm

Peripatopsis capensis is a species of velvet worm in the Peripatopsidae family. This species has 18 pairs of legs: 17 pregenital leg pairs with claws plus one last pair that is strongly reduced and without claws or spinous pads. The native range of this species is limited to the Cape Penninsula of South Africa.

<i>Syllis ramosa</i> Species of annelid worm

Syllis ramosa is a species of polychaete worm in the family Syllidae. It is found in the deep sea where it lives within the tissues of a sponge. It was the first branching polychaete worm to be discovered, with each worm having a single head and multiple anuses.

<i>Ramisyllis multicaudata</i> Species of annelid worm

Ramisyllis multicaudata is a species of polychaete worm in the family Syllidae. It was found in Darwin Harbour, Australia, where it was living within the tissues of a sponge of the genus Petrosia. It was the second branching species of polychaete worm to have been discovered, the first having been Syllis ramosa, a deep water species, more than a century earlier. In 2022, a second species in R. multicaudata's genus, Ramisyllis kingghidorahi, was described from specimens taken off the coast of Sado Island, Japan.

Syllidae Family of annelids

Syllidae is a family of small to medium-sized polychaete worms. Syllids are distinguished from other polychaetes by the presence of a muscular region of the anterior digestive tract known as the proventricle.

Hydroides ezoensis is a species of tube-forming annelid worm in the family Serpulidae. It is native to the temperate northern Pacific and the central Indo-Pacific and is found in the intertidal zone and on submerged rocks, shells, pilings, jetties and boats.

Ramisyllis kingghidorahi is a species of polychaete worm in the family Syllidae. The species lives in the Sea of Japan off Sado Island, Japan, where the holotype was found living within the internal canals of a sponge of the genus Petrosia.
