Hunger the basic need inspires creatures to feed. Hunger so
Intense, that anything would be done to sooth it. Everyone knows how bad it feels to miss supper and go to sleep without food, then having to wake up in the morning and regaining your energy. Well imagine going days without food! Any human would fall victim to malnutrition and lose a massive amount of weight. But not this creature, it is able to go weeks and even months without food. But after this time it is in desperate need for a substantial meal.
This creature is known as the Pit Viper, one of the apex predators in the world. This is a creature built to perfection and designed to kill. After months without food the Viper is in need for a gigantic meal. But low energy is were it's first skill comes into play, it will wait for days and stay hidden ready to ambush till it finds an unsuspecting victim. Finally after days of waiting and months of not eating an unsuspecting creature emerges into sight. The voracious pit viper's brain discharges hormones into the blood stream telling fat reserves to release their energy to the muscles and senses.
The Viper's fat deposits have done their part so it is up to the senses to do the rest. The first obstacle to overcome is that it is nighttime including a new moon. With no light means the viper can't see but this wont be a problem, because this guy can see in inferred to spot his warm blooded pray. This makes the prey glow in the dark as a lantern does in a dark forest. In addition he also has his forked tounge to effectively taste the air.
The target is locked on and are perfect predator is ready to strike. Now it's just another waiting game, waiting for the right moment to strike our are helpless cute and furry bunny. As the rabbit comes within striking distance, then suddenly all of the muscles in the vipers tense lunging it forward jaws agape piercing the rabbits flesh.
