Kraken The kraken ( ) is a legendary sea monster of giant size that is said to dwell off the coasts of Norway and Greenland. Authors over the years have postulated that the legend originated from sightings of giant squids that may grow to 12–15 meters (40–50 feet) in length. The sheer size and fearsome appearance attributed to the kraken have made it a common ocean-dwelling monster in various fictional works. It was first described by the Dane Erik Pontoppidan in 1752–3.

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.

Ascaris Ascaris is a genus of parasitic nematode worms known as the "small intestinal roundworms", which is a type of helminth (parasitic worm). One species, "Ascaris lumbricoides", affects humans and causes the disease ascariasis. Another species, "Ascaris suum", typically infects pigs. "Parascaris equorum", the equine roundworm, is also commonly called an "Ascarid".

Anomalocaris Anomalocaris ("abnormal shrimp") is an extinct genus of anomalocaridid, a family of animals thought to be closely related to ancestral arthropods. The first fossils of "Anomalocaris" were discovered in the "Ogygopsis" Shale by Joseph Frederick Whiteaves, with more examples found by Charles Doolittle Walcott in the famed Burgess Shale. Originally several fossilized parts discovered separately (the mouth, feeding appendages and tail) were thought to be three separate creatures, a misapprehension corrected by Harry B. Whittington and Derek Briggs in a 1985 journal article.

Ramisyllis multicaudata 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.

Shipworms The shipworms are marine bivalve molluscs in the family Teredinidae: a group of saltwater clams with long, soft, naked bodies. They are notorious for boring into (and commonly eventually destroying) wood that is immersed in sea water, including such structures as wooden piers, docks and ships; they drill passages by means of a pair of very small shells borne at one end, with which they rasp their way through. Sometimes called "termites of the sea", they also are known as "Teredo worms" or simply Teredo, from the Greek τερηδών "teredōn", via Latin. Eventually biologists adopted the common name "Teredo" as the name for the best-known genus. On April 17, 2017, it was reported that live giant tube shipworms "Kuphus polythamia" had been discovered in the Philippines.

Aardwolf The aardwolf ("Proteles cristata") is a small, insectivorous mammal, native to East and Southern Africa. Its name means "earth wolf" in Afrikaans and Dutch. It is also called "maanhaar jackal" (Afrikaans for "mane jackal") or "civet hyena", based on its habit of secreting substances from its anal gland, a characteristic shared with the civet. The aardwolf is in the same family as the hyena. Unlike many of its relatives in the order Carnivora, the aardwolf does not hunt large animals. It eats insects, mainly termites – one aardwolf can eat about 250,000 termites during a single night, using its long, sticky tongue to capture them. The aardwolf lives in the shrublands of eastern and southern Africa – open lands covered with stunted trees and shrubs. It is nocturnal, resting in burrows during the day and emerging at night to seek food. Its diet consists mainly of termites and insect larvae.

Strongyloides procyonis Strongyloides procyonis is a parasitic roundworm infecting the small intestine of the raccoon, "Procyon lotor", hence its name. It was first described from Louisiana. It is morphologically similar to "S. stercoralis", and as such infections of "S. procyonis" in humans, dogs, and other animals might be mistaken for the former.

Loch Ness Loch Ness ( ; Scottish Gaelic: "Loch Nis" ] ) is a large, deep, freshwater loch in the Scottish Highlands extending for approximately 37 km southwest of Inverness. Its surface is 52 ft above sea level. Loch Ness is best known for alleged sightings of the cryptozoological Loch Ness Monster, also known affectionately as "Nessie". It is connected at the southern end by the River Oich and a section of the Caledonian Canal to Loch Oich. At the northern end there is the Bona Narrows which opens out into Loch Dochfour, which feeds the River Ness and a further section of canal to Inverness. It is one of a series of interconnected, murky bodies of water in Scotland; its water visibility is exceptionally low due to a high peat content in the surrounding soil.

Ascaris suum Ascaris suum, also known as large roundworm of pigs, is a parasitic nematode that causes ascariasis in pigs. While roundworms in pigs and humans are today considered as two species, "A. suum" and "A. lumbricoides", with different hosts, cross infection between humans and pigs is possible, so researchers have argued they are the same species. Ascariasis is associated with contact to pigs and pig manure in Denmark.

Giant grouper The giant grouper ("Epinephelus lanceolatus"), also known as the brindlebass, brown spotted cod, or bumblebee grouper, and as the Queensland grouper in Australia, is the largest bony fish found in coral reefs, and the aquatic emblem of Queensland. It is found from near the surface to depths of 100 m at reefs throughout the Indo-Pacific region, with the exception of the Persian Gulf. It also enters estuaries, such as the lowermost part of the Brisbane River. It reaches up to 2.7 m in length and 400 kg in weight; unconfirmed reports of it growing much bigger exist, up to 4.26 m and 598 kg . Giant groupers feed on a variety of marine life, including small sharks and juvenile sea turtles. Due to overfishing, this species has declined drastically in many regions, and as of the mid-1990s, it is considered Vulnerable by the IUCN.
