Karl Kraepelin Karl Matthias Friedrich Magnus Kraepelin (14 December 1848 Neustrelitz – 28 June 1915 Hamburg), was a German naturalist who specialised in the study of scorpions, centipedes, spiders and solfugids, and was noted for his monograph ""Scorpiones und Pedipalpi"" (Berlin) in 1899, which was an exhaustive survey of the taxonomy of the Order Scorpiones. From 1889–1914 he was Director of the "Naturhistorisches Museum Hamburg ", which was destroyed during World War II, and worked on myriapods from 1901–1916.

Scorpion Scorpions are predatory arachnids of the order Scorpiones. They have eight legs and are easily recognized by the pair of grasping pedipalps and the narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous stinger. Scorpions range in size from 9 mm / 0.3 in. ("Typhlochactas mitchelli") to 23 cm / 9 in. ("Heterometrus swammerdami").

Bird of prey Bird of prey or predatory bird, also known as raptors, refers to several species of birds that hunt and feed on rodents and other small animals. The term "raptor" is derived from the Latin word "rapere", meaning to seize or take by force. These birds are characterized by keen vision that allows them to detect their prey during flight, as well as powerful talons and beaks.

1884 in paleontology Paleontology or palaeontology (from Greek: "paleo", "ancient"; "ontos", "being"; and "logos", "knowledge") is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that published in the year 1884.

Aspinothoracidi Aspinothoracidi is a clade of placoderms, extinct armored fish most diverse during the Devonian. The gigantic apex predator "Dinichthys", is the best-known member of this group. Many other genera, such as the infamous "Dunkleosteus", were previously thought to be close relatives of "Dinichthys" and were grouped together in the family Dinichthyidae, though more recent studies have restricted that family to only its type species.

Spider Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization. s of November 2015 , at least 45,700 spider species, and 113 families have been recorded by taxonomists. However, there has been dissension within the scientific community as to how all these families should be classified, as evidenced by the over 20 different classifications that have been proposed since 1900.

Teuthidodrilus Teuthidodrilus (also known as the squidworm), is a genus of marine polychaete worms first described by marine biologists from the Scripps Institution of Oceanography in November 2010. This unique animal is currently believed to represent a "transitional organism", with physical and behavioral characteristics of both benthic (seabed-dwelling) and pelagic (free-swimming) organisms. "Teuthidodrilus samae" is currently the only described species of this genus. "Teuthidodrilus" is closely related to the recently discovered "Swima" genus, another pelagic cirratuliform worm of the deep ocean.

David Hirst (arachnologist) David B. Hirst is an arachnologist previously based at the South Australian Museum in Adelaide. He left the Museum on 22 February 2011. He has described more than 40 species and genera in the Sparassidae (huntsman spider) family, and was regularly called on by New Zealand authorities to identify huntsman spiders that entered their country.

Ichthyology Ichthyology (from Greek: ἰχθύς, "ikhthus", "fish"; and λόγος, "logos", "study"), also known as fish science, is the branch of zoology devoted to the study of fish. This includes bony fish (Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). While a large number of species have been discovered, approximately 250 new species are officially described by science each year. According to FishBase, 33,400 species of fish had been described by October 2016.

Living dinosaur Living dinosaurs are non-avian dinosaurs that may have survived the Cretaceous–Paleogene (K–Pg) extinction event. The term is used in the scientific fields of paleontology and biology (as well as the pseudoscience of cryptozoology) to refer to different creatures. In paleontology, all non-avian dinosaurs are believed to have gone extinct during the K–Pg extinction event, round 5 million years ago, but there is some scattered evidence that some may have survived into the Paleocene epoch. These alleged creatures are referred to as living dinosaurs. In biology, the term is sometimes used to describe birds, which are the only living clade of dinosaurs today. In cryptozoology, where the term is often used, it refers to any legendary or folkloric creature that resembles the dinosaurs (such as the Loch Ness Monster), which cryptozoologists allege are dinosaurs that have survived into modern times. Excluding a few controversial claims, scientists agree that all non-avian dinosaurs became extinct at the K–Pg boundary.

Parateuthis Parateuthis tunicata, the only known member of the genus Parateuthis, is the scientific name currently given to a species of squid based on a single specimen. The validity of "Parateuthis" and of "P. tunicata" is uncertain. The sole specimen was found in the Antarctic Ocean, and is held in the repository at the Museum für Naturkunde in Berlin, Germany.

Kapes (genus) Kapes is an extinct genus of procolophonid parareptile from the Lower and Middle Triassic of the United Kingdom and Russia. It is a member of the subfamily Procolophoninae. The type species "K. amaenus" was named in 1975 from the banks of the Vychegda River in the Komi Republic of Russia. In 1983, a new species was brought into the genus, "K. majmesculae". "K. majmesculae" was first named in 1968 as a member of the genus "Tichvinskia". A third Russian species, "K. serotinus", was named in 1991. In 2002, "Kapes bentoni" was named from the Middle Triassic Otter Sandstone Formation of Devon, England, extending the geographic range of "Kapes". In the same paper, "K. serotinus" was synonymized with "K. majmesculae" and another Russian species was assigned to "Kapes" called "K. komiensis". "K. komiensis" was first named in 1975 (in the same paper "K. amaenus" was named in) as a member of the genus "Macrophon".

Slimonia Slimonia is a genus of Silurian eurypterid roughly similar to the genus "Pterygotus". "Slimonia" resembled "Pterygotus", save that the former's telson is larger, and that its body was smaller and more slender than the latter. Unlike "Pterygotus", which lived in estuaries, "Slimonia" species lived exclusively in freshwater environments. "Slimonia" preyed on smaller fish, such as heterostracans and early osteostracans by seizing and rending them with its large chelicerae. The largest species of "Slimonia" was extremely long, around two meters. It carried its body on spindly legs and was likely an ambush predator. The lungs of the species were located on the underside of the body in a series of folds. "Slimonia's" telson was used much like that of a scorpion to subdue prey, but were scorpion tails flex upward and over when used in an attack, "Slimonia's" was seemingly more suited to flex from side-to-side. Using its small but powerful front limbs to hold its victims firmly, "Slimonia" would then slash and cut its victims with the spike on its telson to kill the intended prey item.
