Been working on some of the aquatic creatures in my region:


Grevmoore:

Large, multi-finned , predatory fish of the northern coasts. A unique property of the grevmoore is that they have unusually long, slender bodies and tails: their muscular tails often times account for almost half their length and bulk. Such tails are needed in order to catch prey, as well to evade predators, such as the huarkemnell and mirgran eel.
Male species commonly reach lengths of 67 centimeters and weigh 11.49 kilograms; female specimens reach lengths of 54 centimeters and a weight of 8.46. Males have a dark blue and black pattern along their backs, a white underbelly, and vibrant vermillion markings along their eyes and gills.

Grevmoore commonly feed on smaller fishes (such as the feldon and flinscythe), the eggs of the unique aquatic creature nathir, and supplements its diet with seaweed and emberour kelp.


Vaelgardian luirana manta:

Larger, genetic variant of the common luirana manta. This form of the luirana has forgone the idea of a poisonous stinger as a method of defense, and has instead formed plates of chitin around various areas of its increased bulk. Due to the frigid waters of Vaelgard, this version of the luirana has increased its bulk and developed a thick layer of fat around its body. Although usually found to be moving quite slowly, the manta can sprint short distances – hoping desperately to find a safe niche in a rock face.

Males commonly grow to a size of 26.34 kilograms, and females many times reach a weight of 20.89 kilograms. Both sexes have cerulean backs, pearl underbellies with black spots, and deep violet tails. The only difference between male and female marking lies in the wing tips: males have vibrant violet tips.

Vaelgardian luirana manta feed on small ocean life (such as the serean plankton and budina minnow).


Feldon
The feldon is a docile, medium sized fish that is considered a delicacy in most areas of the world.


Thianmathra

The thianmathra is a larger, more aggressive relative of the hydro dragon of warmer climates. This beast of the icy deep is armed with large, imposing teeth, which it uses for hunting and combative behavior. The beast also has four limbs, of which have large fins and claws to aid in the creature’s propulsion and combat, respectively. A pointed ridge of bones lines the creature’s back, which acts as armour.

Male specimens average a length of 11.58 metres and weigh 843.26 kilograms; females measure 10.11 metres and weigh 792.14 kilograms. Females are coloured a dark violet-blue with a light blue underside and lining around the mouth. Males are pearl white with crimson markings along their limbs and eyes. Native legends nickname the creature “Pale of the Deep”.

Thianmathra feed on various species of whales, sharks, klimfaer.
There are very few thianmathra, and they live extraordinarily long lives (470 or more years of age). Only a handful have ever been found dead, and even less slain by men. Although slaying such a creature would grant the victor a fortune, the price of one’s own life is too high of a risk for any sane man.
