Poisonlandminemantaraybats

Poisonlandminemantaraybat is a highly dangerous air- and water-based animal endemic to Earth. It is technically classified as a fish, but can also survive on land sometimes for extended periods of time.

Physiology
Poisonlandminemantaraybats usually have a torso of about thirty centimeters in length. They have two fins resembling that of a bat, and their adult wingspan is about a meter. They have no discernible feet or tail to speak of.

A poisonlandmimemantaraybat can dislocate its jaw and is capable of swallowing prey larger than itself. It has four sharp fangs on either jaw, and a row of smaller, jagged teeth to rip flesh from bones. Its fangs secrete a mildly poisonous substance than can paralyze smaller prey.

Poisonlandminemantaraybats are nearly blind, and use their eyes only to detect the source and intensity of light. Instead they rely on their keen sense of smell, hearing and fluid vibrations.

As their name suggests, poisonlandminemantaraybats are capable of violent explosion as a last-resort offense.

Behavior
Poisonlandminemantaraybats have both predatory and scavenger traits. They will hunt down smaller animals such as birds and any fish smaller than trouts. They will also scavenge larger corpses by extending their flexible jaws, and attempting to swallow them whole.

Poisonlandmimemantaraybats are solitary animals. They only group together during mating season. The male and female will build a small nest on the ocean floor at about the depth of 20 meters, after which they will protect the eggs from rival poisonmantaraybats and other predatory fish.

Trivia

 * While humans hardly ever encounter poisonlandminemantaraybats, awareness and self-protection against them are highly regarded in coastal areas of West Pacific Ocean. The most effective offense against an attack is a direct hit onto the poisonlandmimemantaraybat's face with a double-shotgun. That is, a shotgun with no less than four barrels firing simultaneously.
 * Poisonlandminemantaraybats were used as opponents in the 532nd World's Toughest Stick-man competition in 32011. One of the 10 finalists was almost eliminated by one, but was saved by the rarely-applied double-yolk-rule.
 * Piggy has died to poisonlandminemantarays in several incarnations.
