Oceans Worldwide
These creatures are so prevalent that they can be found in oceans worldwide, though many are known to migrate, or vary slightly from place to place.
Sea Orm, Jormungandr. Super Eel, The largest of all eels and one of the most notorious of sea serpents, it lives mainly in the depths and feeds on large fish and squid. When encountered on the surface or caught in nets, it will cause considerable commotion. 25 meters long, 35 tons. Congridae.
Serra, a very large and ferocious fish resembling the wahoo and Spanish mackerel. 4 meters long, 200 kilograms. Scombridae.
Lyngbakur, Fastitocalon, Hafgufa, Jasconius the largest and most legendary of the baleen whales, found in many places, though it is most notorious in the north. 30 meters long and 200 tons. Balaenopteridae.
Champagne's Serpent Whale, This rather shy species of beaked whale is sometimes seen at the ocean's surface. 9 meters long 6.5 tons. Ziphiidae.
Great Glowing Squid. Sighted numerous times on the high seas in different parts of the world, this huge squid is known to migrate to surface waters at night in order to feed. It is especially notable for possessing an array of bioluminescent organs, which it uses to communicate, and to attract prey. 12 meters long not counting feeding tentacles, 6 tons, Onychoteuthidae.
The Black Carpet is a notorious and ominous colonial organism of the deep oceans, remarkable for attaining great sizes. Made up of thousands of zooids whose numbers increase or decrease based on resources and sea currents, it can be so large as to be mistaken for a section of the sea floor. Most apparent are masses of black filaments, being the stinging feeding tentacles of each zooid, but the larger arm-like growths are actually propulsive zooids which can be directed to push water out and adjust the trajectory and position of the colony. Much its interior is concealed by adhering congelations of debris and algae that are accrued by the organism as camouflage. Though frightening in size, most of its prey is no larger than a fish, it relies on the collective efforts of all of its feeding zooids to nourish the colony. Up to 1.6 kilometers in diameter at full extension, weight not determined. Siphonophorae incertae sedis.
Bosch, this hand-sized leathery mollusc has attracted many myths of ill omen among pirates and sailors. Commonly attaches itself to ships and stows away in bilge water. 22cm long. Acanthochitonidae.
Megalodon, Davy Jones, this ferocious giant shark is legendary in its depredations on whales and sometimes even small ships. 20 meters long, 55 tons. Genus Otodus.
Leviathan, Rahab, Derketo, Hedammu, Cirein-cròin, Bo-dree-more or Tiamat, a huge sea dragon which commonly preys on whales and sailors. 20 meters long, 65 tons. Tylosaurinae.
Kraken or Supergiant Squid, one of the most legendary of all sea monsters, it is able to prey on sharks, whales and sailors alike. Will attack ships. 46 meters long 150 tons. Cranchiidae.
Triton, Merrow or Merfolk. Also known as Sea People, Ningyo, Renyu, Havfrue, Ben-varrey, Mereminne, Kulullû, Nereid or Water-Sprite. These deceitful creatures are a kind of primate, though resemblance to humans is exaggerated. 1.6 meters long, 80 kilograms. Cercopithecoidea.
Valhalla Serpent, this large marine reptile has relatives dating back to the Triassic, and can sometimes be seen basking on the surface. 12 meters long maximum, 7 tons. Nothosauridae.
Daedalus Serpent, this giant marine snake is relatively rigid, hunting in the open ocean by casting a shadow in order to attract fish seeking shelter. 24 meters long maximum, 30 tons. Alethinophidia.
Morgawr, Longicollis or Longneck, shy by nature and seldom seen, they cast a distinctive profile when spy hopping, something like a periscope. Generally afraid of ships, prefers calm weather. 10 meters long, 5.5 tons. Plesiosauria.
Aspidochelone, World Turtle or Father of all the Turtles. This ocean wanderer is large enough so that its dried shell may be used to make a hut, when seen they are plainly visible on the surface of the ocean. 8 meters carapace length, 6.5 tons. Protostegidae.
Murex, these shellfish wander the open ocean, afloat in the water column and undulating their “foot”. 1 meter long, 7 kilograms. Littorinimorpha.
Many-Humped Serpent, Scoliophis, Great Sea Serpent. These large archaic whales bear a series of humps down their back, which makes a distinct profile. 25 meters long 60 tons. Basilosauridae.
Trolual, Devil-whale, Nauthveli. This variety of sperm-whale is large and pugnacious, and will sometimes attack ships. 20 meters long, 55 tons. Physeteridae.
Ziphius, this deep-water hunter has large eyes and does not make sonar calls; it preys mainly on squid of the abyss but will sometimes attack surface-dwelling prey. 13 meters long, 11 tons. Mammalodontidae.
Cousteau's Set-square Fish is a moderately-sized, unusually-shaped silvery fish living at depths of up to 300 feet. It is also a rather specialised prehistoric holdover from the Cretaceous. 50 centimeters in bodily height, Pycnodontidae.
Chinese Checkerboard Animal. This unusually-shaped, abyssal radial organism was first attributed as Problematica, but is now known to be closely related to Medusa jellies. Diameter 20 centimetres, Scyphozoa incertae sedis.
Grassle's Undulating Hairbrush. This unusual abyssal sea-cucumber is related to other forms seen in the deeps, and is notably able to swim in the water column via an undulating muscular action of its body and tail. 25 centimetres long, Psychropotidae.
Lophenteropneust, this unusual worm-like creature is relatively common on abyssal sea floors, and is notable in being an evolutionary link between Pterobranchs (sea angels) and Enteropneusts (acorn worms). Up to 1 meter long, Hemichordata.
Lazarus Trilobite, known mostly from its tracks which resemble fossils dating back up to 500 million years, this ancient survivor is relatively common on the deep-sea floor. Up to 12 centimetres long. Proetida.
