'Grappler sharks' live near the surface and use the eyes on the tops of their heads as light meters to camouflage their bodies to prey that swims beneath them. Though fast on their own, they prefer to sneak up on prey and latch onto it with their pharyngeal jaws before reeling it in. In this illustration it's attacking a human in an uncharacteristic fashion, adding to the many accounts of bizarre or aggressive behavior the planet's animals exhibit in the presence of humans...
When you get into creature design, you learn very quickly that there are no original designs-- in some way shape or form, mother nature's made it happen on our planet already.
Oooh, I've seen those guys before. I might have been influenced by them more while working on my other creature sketches. Some of those concepts were much more arthropod-inspired.
dude a tongue is just creepy but a Jaw latching onto you...You know what you my friend should be designing new creatures for Avatar (Movie) or something! This is pure originality!
I took inspiration from the pharyngeal jaws of the moral eel and goblin sharks, and attached them to a long tongue-like structure in the mouth of the beast. It darts out like the tongue of a chameleon or frog, but the muscles in the tongue allow it to "swim" (hence the round fin-like outcroppings on the corners of the jaw). After closing, the shark can reel in the pray, or reel itself in, depending on the size of the catch. The large paddle-like fins in the front of the beast allow for extra bursts in speed, or to push backwards when reeling in prey. The large dorsal fin that runs the length of the shark's back it used to detect vibrations in the water, and to appear larger when herding groups of prey. Unlike Earth's sharks though, they tend to hunt alone, preferring stealth over brute force, as there are larger, more clever creatures that live in the same waters...
(tiny question - was Obinia an influence, with the trunk)
superb image.
its still a great creature you've created.
