"Sand Sharks. Probably the one animal on Haven I can say I actually despise. Imagine my shock as while taking a nice stroll down the warm sands of the Auit-Islet, only to almost lose both of my legs from a beast that should never exist on land. There's not enough money in the Universe to make me go back to that blasted island again."-William Tancard's: Guide to Haven's Glorious Creatures.
The Sand Sharks are a rare species of terrestrial Ichthyoid (fish) native exclusively to the Auit-Islet of the Theltheim Isles. They resemble many shark species native to many worlds including other shark species of Haven, and they are one of the only terrestrial sharks on Haven. They are very rare, with a global population of only around Five hundred, as well, they are only known to inhabit the small island of the Auit-Islet, and are not found anywhere else in the world. They have an appearance very similar to many different species of sharks, such as the Tiger Shark. They are a very aggressive predatory species, often feeding on any creature unfortunate enough to cross within their path.
Despite their low numbers, they are extremely infamous to the inhabitants of the Auit-Islet and the wider the Thelthiem Isles due to their fearful nature and behavior, making many weary of traversing the open sands of the island.
Sand Sharks, while technically being a fish, actually live on land, but despite this, it has almost the same physiology to that of a sea-dwelling Icthyoid. They have two front facing eyes, a large mouth with twenty-eight razor sharp sets of replaceable teeth, and a two nostril nose. It will take a Sand Shark around five standard years to fully mature, with females being able to lay around thirty eggs at once. The largest Sand Shark known measures around nine feet long (two meters), but despite their fairly mundane size they require a constant supply of meat to survive, needing at least one ton of fresh meat a day, making them constantly on the hunt, taking anything they can get.
With their large fins, an individual Sand Shark is able to skirt across the sands at incredible speeds, clocking in at a maximum speed of sixty-eight kilometers per hour, making them a living missile. Typically, their dorsal fin will stick above the sands, and the sand will be disturbed, making large clouds surrounding it, giving creatures ample warning of their approach. But despite how obvious they are, due to their extreme speeds and incredible agility, being able to turn in any direction underneath the sands in seconds, it's almost impossible to escape them on land.
Along with their speed, the Sand Shark has some of the most powerful jaws of any creature on Haven, with a biting force of around thirty thousand pounds per square inch, thanks to the incredibly powerful muscles all around their mouths. The teeth themselves are also extremely sharp, being able to puncture skin with minimal effort, however they are fairly brittle, often cracking and or falling off, but thanks to their interchanging rows of teeth, it almost never affects them.
Sand Sharks have a suite of sensory abilities, with an average hearing range of around a half of a kilometer, as well as an eye sight that allows them to see things up to seven kilometers away. However, the two most powerful sensory organs they posses is their nose and their skin. Their nose has been developed to be able to detect small sand burrowing animals native to the Auit-Islet, in a range of around a kilometer, making an individual Sand Shark acutely aware of most creatures in their immediate vicinity.
Their skin is able to detect vibrations of the sands above them, allowing them to shoot up on unsuspecting prey. Along with the sensory capabilities, their skin is extremely solid, as they need to contend with rival Sand Sharks fairly regularly, leaving them riddled scars and deep gashes.
The most prevalent behavioral trait of Sand Sharks is their extremely aggressive behavior towards anything that comes anywhere near them, often attacking things they have no hope of contending against simply because they crossed within an arbitrary threshold of some kind. This often includes other Sand Sharks, as they often will cross paths, leading to spectacular battles to be waged.
When a female Sand Shark is pregnant, their aggressive behavior will be increased ten fold, as it requires a larger quantity of meat, settling for anything within its grasp. After their young fully mature, then they will often not recognize them as their own progeny and will attack on instinct, leading to a high mortality rate fore newly formed adult Sand Sharks.
