Future Adaptations:Stingray


Survival of the Stingray


Imagine yourself 150,000 years in the future. Another ice age is in full force.


Temperatures are much colder, vegetation has ceased to exist, along with several


entire animal


species. The lion, once the king of the jungle, is no more than an alley cat scavenging


for food.


The great white shark- reduced to the size of goldfish. A new predator is on the prowl.


The


stingray, once limited to shallow, sandy beaches, has evolved! With it’s new


adaptations the power


of the stingray is unfurled, free to roam in the wide expanse of sea, air, and land.


Many advantages have evolved in the once conservative stingray. From the large


size of


the present day animal, the stingray has been reduced in size and weight from an


average of 12


feet, 60 pounds to 3 feet, 15 pounds to provide from speed, stealth, and agility. The


broad flattened


pectoral fins have grown a protective hard scale resistant to the hardest of an enemy’s


teeth, along


with the secretion of a special enzyme that causes pain and damage along with a


bitter taste to


avoid being eaten. It’s powerful tail has been lengthened to provide offensive


coverage in a 360


degree area. Along with the sharp, barbed spines and deadly poisonous glands, the


stingray is now


an formidable

opponent.


With the decrease in food supply, the stingray has adapted with his environment.


Formerly


a sole marine animal, a stingray’s diet has now included the usual fish and


crustaceans to birds and


small rodents. To achieve this new source of food, the stingray now has the capability


to move on


land in the form of a speedy slithering such as a snake might move. A set of lungs


accompany this


adaptation enabling the stingray to breathe on land as well as water. In addition to


land and sea, if


a stingray should swim swiftly to the surface and break out high above, his new


capability to glide


would take effect. With a limit of a few minutes the stingray cannot sustain continued


flight. He


would be able to act as a scavenger stealing away kills from other predators and


returning to the


murky depths. The bland coloring of his skin enables him to hide from the predators


as his skin


reflects off the colors surrounding his environment.


In a land surrounded by ice and water, a hard nose tooth, similar to a tusk, has grown


to


allow the stingray to break into crevices where urchins and such may be hiding. This


also enables


him to use the tooth as a weapon against invaders. In the harsh conditions of this new


ice age, the


stingray has evolved a number of advantages that should ensure their life span of


their species well


into the future.
