a tala'nynn creature :D finally i could color the sketch.
information:

The creature possesses soft, rubbery skin, it cannot stay away from water for a very long time.
Slug belly: Capable to stick over rocks or corals, to use as stealth or just for hiding.
They got a very hard head, used mostly to fight between their species for a female or for a male [this means that both females or males can fight for one of the oposite sex]
Breathing system: it's a mixture of a slug system and a Fish system: in the skin there are some glands where they absorb the water [H2O] and then Throw away CO2. The tapping of these glands can cause the death of the creature. this happens rarely, but there are small parasites that can tap the water channels. this normally happens to those who prefer devouring their cleaner fish instead of letting them eat the parasites.
the work cycle of work of these glands appears here: http://www.furaffinity.net/view/3887004/
unlike normal sharks, these dont have a good vision,, so they rely on their arsenal of senses [touch, smell, hearing] and their extra senses [Heat and Electric sensors]
Their nostrils are only used for the smell, and like any shark, they can smell a small blood cell from a long distance.
their heat sensors are located just over the mouth. with these they can detect the smallest change in the temperature of the world that surrounds them
Electrical sensors: they got millions of small electrical sensors, that they use to detect even the smallest electrical pulse caused by the movement of muscles of another creature.

Diet: Their diet basically is based in Large Fish, aquatic mammals, and birds. but there are known cases of them attacking and devouring other taschevah that were flying near the water, or swimming in the water.

species design- me.
