Deep-sea merfolk

(Ti sei perso, viaggiatore? Se stai cercando questa pagina in italiano, puoi trovarla QUI!)  

Deep-sea mermaids (Abyssugens hispida) are sentient creatures that inhabit the deep sea, unable to survive naturally at low pressures, especially long periods out of the water.

Despite their misleading name, deep-sea mermaids are not part of the merfolk family, although deep-sea mermaids were once mistakenly classified as Maregens hispida.

Abyssugens are mysterious creatures, statistically almost never coming into contact with surface creatures. They are highly intelligent, but any rare interaction with other sentient creatures has invariably labeled them "weird": speaking a completely different language and living a solitary lifestyle in the deep, where concepts and priorities are markedly different from those of the surface waters or even on land, can make communication with a creature unlike themselves difficult.

Abyssal sirens have been reported to be capable of creating exquisitely effective magical artifacts; they are resourceful alchemists and artisans, inventing any trick to make their lives easier. They are true opportunists, seeking maximum yield from minimum effort, a trait necessary for them to survive in the harsh environment of the abyssal depths.
They are also called abyssal merfolk, people of the abyss, or simply abyssals.

Appearance and Physiology

Deep-sea merfolk have decidedly less human-like features than their surface counterparts, the Maregens. Their heads are more flattened, with a blunt but more prominent snout, slightly upward-pointing, revealing a pair of mouths, both functional and equipped with thin, sharp teeth, designed to tear flesh and hold prey during their lightning-fast attacks. Their nostrils are slanted and sensitive.

It has been reported that, although both are perfectly functional for both sound and feeding, many deep-sea sirens prefer to eat from one mouth and sing from the other. Over time, the singing mouth's tongue thickens and becomes more trained, making it visible to the eye which is which; both tongues are mobile and pointed, smooth, and pink.

Their skin is thick and tough, covered with tiny, adapted scales whose structure and shape are vaguely similar to those of the placoid scales of sharks and rays, which leave room for photophores. As pups, they lack these, so their internal organs and veins can be seen through their delicate skin.

Deep-sea merfolk have an elongated, almost tapered silhouette, with a distinctive posture that sees them hunched forward. They tend to remain static, upright when at rest; they have a prominent, jagged-looking dorsal fin, an anal fin, and a large, modified caudal fin, which has split to be flanked by two smaller fins (more abundant in photophores; it is uncertain whether these are decorative or somehow enhance their swimming ability). On the upper body, they have two double-jointed limbs (at the elbow and wrist), called arms, capable of rapid, wide movements, culminating in bony, webbed, prehensile hands with opposable thumbs. They also have backward-pointing bony tips at the elbow.

Their large, round eyes are lidless, revealing the large white ring of the sclera. They are surrounded by photophores on the skin that emit a pale blue or aquamarine light on command, allowing them to pierce the darkness of the abyss and gaze around comfortably. Due to the arrangement of the photophores, it might seem as if their eyes themselves are glowing, but this is not the case. Unlike fish, they are not fixed, and a deep-sea mermaid can rotate them in their sockets to direct her gaze at will; at rest, they exhibit a certain lack of focus.

In addition to their eye contours, deep-sea merfolk have a high concentration of photophores on their tails, which can create impressive light displays. These patterns are generally slightly different from one individual to another, and they do so from birth, which is why a single flash is enough for a deep-sea mermaid to recognize a previously encountered individual. Deep-sea merfolk' bioluminescence is possible thanks to specialized mitochondrial cells within their bodies called "photocytes," which create light internally by oxidizing a protein called luciferin, bringing it into contact with the enzyme luciferase. These photocytes are found inside the photophores, organs contained in the skin of deep-sea merfolk and several other deep-sea organisms. They have a glandular portion, from which the light emanates, a reflective layer lining the bottom, and refractive devices, a sort of organic lens that condenses the light.

Given the low temperatures, the most delicate parts of deep-sea merfolk's bodies are protected by thick gray or white fur, which grows around the head and throat, leaving the gills exposed. These are protected by both a gill cover and tufts that grow on the jaw and cover the respiratory openings when viewed from the front.

The bones of deep-sea merfolk are light and relatively flexible, yet fragile due to the difficulty in obtaining calcium at the depths where they live.

Their stomachs are more elastic than those of many other animals, allowing them to eat and store as much as possible if they manage to find a large amount of food at once.

Behavior

Sociability

Deep-sea mermaids mostly lead solitary lives, except for the time mothers and their young spend together during the young's early development.

The mother remains with her young for the first five years of their lives, providing protection, food, and teaching. The fries group together in small platoons (a term that in Maregens and Abyssugens indicates medium-sized groups of four to thirty individuals). The mother's attitude, while loving, is far from purely altruistic: to avoid getting lost in the darkness of the deep sea, the young deep-sea merfolk make extensive use of bioluminescence and sing small, high-pitched, melodious calls to signal their presence to their family. However, by doing so, they also attract various predators, which the mother, using her young as bait, can catch and devour much more easily. The song of the young deep-sea sharks has been compared to that of a songbird: high-pitched, sometimes modulated, but somehow "eerie" or "nostalgic" to human ears.

By the time they're five years old, deep-sea merfolk have become too large for their mother to benefit from sharing food with them, so she stops feeding them and encourages them to find a different area to live in. At that point, the young disperse and will likely live isolated lives that may or may not be interrupted by a brief encounter with another of their kind and, perhaps, a fortunate mating.

Even as adults, they retain charming, harmonious voices, a characteristic likely unique for creatures of their habitat. They are significantly less capable of ranging the sounds they emit and replicating the speech of other creatures than merfolk, especially considering that speech has little or no use for them beyond the age of five; the long-distance call they emit to advertise their location and availability to potential mates has been described as a sort of melodious "whine," a mix between the song of a whale and that of a great black-throated loon.
