Description
Some fish of Subterramundus (Not to scale). You might remember the name sarcodont from this previous deviation: www.deviantart.com/noahsaurus5…
These are those same fish, slightly redesigned and colourised.
The most dangerous fish in the caverns are from a family called sarcodonts. These fish are distinguished by their strong jaws, highly carnivorous diet and their ability to leave the water for several days as long as they remain moist, which given Subterramundus’ warm humid environment is a very long time.
One species in particular excels at terrestrial life. The horrible landfish (horrichthyopterus) (flat green) frequently crawls onto land and half buries itself in mud to ambush prey like small animals like juvenile dinosaurs. They will also bite chunks off larger animals if they are not careful.
The 5 meter long death eel (long silvery) is a specialist that generally prefers crustaceans and small prey, but they will still bite anything in range.
The smallest sarcodont is the hellspawn piranha (green and red). This fish is, as the name suggests, a voracious predator which with the help of a pack can devour mid sized prey in a matter of minutes, their sharp interlocking teeth enabling them to easily rip chunks of flesh out of prey.
The biggest sarcodont is the green croctooth (top). This is a generalist predator which both hunts small prey and scavenges larger animals. Their jaws are extremely strong which aids them in dissecting tough food.
Another generalist predator and scavenger is the hellfish (lower left). It performs the same basic duties as the croctooth but its smaller size means it can escape most theropod and crocodilian predators.
Finally, the devil gapefish (big mouth) is an opportunistic bottom feeder that uses an extendable mouth to suck up buried prey and with an elastic throat can fit vast quantities of food into its mouth. This means that the gapefish also has the weakest bite of all sarcodonts.
All sarcodonts typically favour meat but will readily eat fallen fruit eggs and fungi that make their way into their waters. Additionally sarcodont jaws are capable of snapping even after the head is cut off. This makes all species difficult to tackle, even for the largest dinosaurs.
