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. <br><br>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 a formidable opponent.<br><br>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
Stingray are newer to the geological time scale, to barely beginning in the Early Triassic period which are from the class of Chondrichthyes. As well that the Chondrichthyes are ancient sharks from the silurian period up until now but have slowly decease in size and shape. Stingrays have shown signs of being one of the evolution of the shark from the 422 period, from its anatomy view of point. The Jaw structure between the shark and the stingray are very similar it's joined bone, and shape to have….
percentage of animal kingdom members. However, members of the stingray suborder have largely been excluded from this research, an unfortunate oversight due to the increasingly concerning decline in worldwide stingray population health and numbers. Through the characterization and differentiation of the conspecific interactions of two representative stingray species, the freshwater tiger stingray, Potamotrygon tigrina, and the marine Atlantic stingray, Dasyatis sabina, we sought to fill in this gap in the….
Curious to see the ever moving stingrays up close I leened over the side of the boat with my camera to examine them. Those stingrays had some very distinktiv features! Its heads were dome-shaped. They had broad blunt noses that seperated their inconspicuous eyes. When they jump out of the water I could see their funny mouths, it looked as if they were smiling. The rays were much biggest than I thought at first, their "wingspan" was about three feet. Because the stingray over lapped each other and….
The major stingray family of the potamotrygoniae occur throughout the major rivers system of the eastern south Americas. Based on research, scientists believed that the potamotrygoniae family had indeed evolved from dasyaitude. Although there is a lot of speculation, scientists assume that the first and early ancestors of the potamotrygonids had dispersed into fresh waters therefore adapting and obtaining their name as “river rays”. This was thought to have occurred during the last….
as the engine. Overall, the 2015 Chevrolet Corvette Stingray is an excellent choice because of it’s fuel efficiency, quality of the vehicle, and the features of the Stingray.
There are three main reasons pertaining to why the Corvette Stingray is a car with very little to no flaws. The principal reason is the price of the car. This car costs $55,000 at base cost and that is a superb price considering the quality of the car. Since the Stingray is a high end car that can be compared with super cars….
