Demoneye Scarabfish
Scarabovenator potens is a large Scarabicephalid Armadilloarmatid amphibian from the seasonal seas of the Leviathan Islands.
Inhabiting the open waters in between the islands, this animal is known to for its aggressiveness and territoriality both towards divers and conspecifics.
Filling up the same niche as certain Shark species did on Earth, the animal prowls the open waters in search of prey with its excellent smell and eyesight; the peculiar shape of the jaw is made to crush bones and armour with ease, while the mass helps to make it the undisputed king of its seas.
The down-pointing head is specially made to help it spot prey from under itself and to protect against attacks from conspecifics or other animals from the same depth layer as it.
Contrary to almost every other Ichthyomorph family on the planet, this animal's dorsal armour is raised over the level of the head, meaning that instead of moving the dorsal armour to make space for the cranial armour while moving the head, this animal moved the cranial armour under the dorsal plate, allowing for increased movability despite the morphology of its armour suggesting the opposite at first glance.
Every year S. potens is reported attacking divers that venture outside the fore reef with an average fatality rate of around 16 people/yearly, plus several other non-fatal encounters.
Harpoon hunting of the species is traditional in several of the islands in the archipelago, usually done while sailing on catamarans or other sail-boats.
Basic Information
Anatomy
- Cranium rounded and downpointed; jaw large and quite high, rectangular in the lower section.
- Cranial armor composed by a single large plate, shield-like in shape.
- Body very high with very strong neck musclolature.
- Ventral armour composed of seven segmentations, covering the jugular section of the throat.
- Pectoral fins spear shaped; Anal I very large and leaf shaped, almost as long as the body itself.
- Anal II and Dorsal fins veiled, Anal II is a bit rounded.
- Gill Tail much thinner than body, creating a bottleneck kind of shape.
- Gill Fan moderate with a soft caudal drop.
Genetics and Reproduction
Seasonally monogamous species.
S. potens mates in early winter, coinciding the time of the birth of the cubs with the return of the migratory Cutthroat Reef Rhinos coming home from New Japan.
Males enter heat a few weeks before the females; the increased hormonal production provokes a sudden surge in muscle growth, making males 25% bigger than when outside the mating season and flashing their colours bright in the cranial area, making it a bright red.
Males, also called "Bulls" will start expanding their territories in search of available partners in, clashing with other males in fights over territory and females; an average male fight is resolved quickly after only one or two charges but some can escalate further.
To spar, the two males charge head down one against the other, clashing the cranial and dorsal armours one against the other until one of the two gives up; a dominant male will produce strong clicks by hitting the two armour pieces together rhythmically, a way of scaring off smaller conspecifics and attract females.
A female will only accept to mate with a dominant male, defeated ones will have to leave the territory before trying again in a different one.
mating can take up to half an hour to finish and the female will incubate the eggs for almost a month before giving birth to two to four live young.
Growth Rate & Stages
Ontogeny not very marked in the species.
Young specimens are born around the time of the return of many migratory species such as the Cutthroat Reef Rhino.
Loss of natal aculeus three months after being born, aculeus is vestigial from birth.
Ecology and Habitats
Epipelagic creature living at depths comprised between 3 and 50 m.
Swims to the bottom of the flat zone to feed, if it sees something big enough to capture its attention.
Dietary Needs and Habits
Active predator feeding on medium sized amphibians, sometimes taking on bigger prey, if in dire need.
Sometimes seen attacking prey as big as Greater Limpadurs, especially during the winter, when food is scarser and they need all the food they can find to survive the season.
Aggressive towards humans, they are reported attacking and killing people every year, they feed on the body.
Biological Cycle
Quite seasonal in nature, the animal enters a period of reduced activity from the start of the annual migration of prey to the beginning of the mating season; they'll have to increse their weight by at least 40% before mating season to survive it.
Additional Information
Social Structure
Lonesome apex predator, doesn't tolerate conspecific in its territory.
Only exception being the mother with the very young offspring.
Domestication
Kept in some public aquarium as a main attraction; this animal is otherwise impossible to keep in captivity due to the big size and diet.
Uses, Products & Exploitation
Of moderate interest in the food industry.
Of importance for local population who traditionally spearfish the animal as a test of courage.
Geographic Origin and Distribution
Perception and Sensory Capabilities
Very good sense of smell and eyesight.
Symbiotic and Parasitic organisms
Afflicted by Intestinal Tube Worms.
In a commensalistic relationship with several smaller amphibians.
Scientific Name
Eoichthyia; Armadilloarmatia; Scarabidichthyioidea; Scarabicephalidae ; Scarabovenator; S. potens
Lifespan

Conservation Status
Near Threatened: the animal is seeing a decline in population numbers due to overfishing of prey species, no measures in place to protect it.
Population trend: DECLINE
