From Prey To Predators Essay

Cold is encircling you, and the deeper you go, the tighter it squeezes. There’s enough light for you to see a dark, looming shape weaving back and forth through the water, slowly heading toward you. It aggressively opens its mouth, ready to gulp you down its starving stomach, and its teeth seem to sparkle with hunger. But something else catches eye. Abruptly bolting past you, it swiftly devours a fish twice its size. Welcome to the Pelagic zone. Large organisms roam this open space, and this is perhaps why another name for it is the Open-ocean zone. Including numerous subzones, this limitless territory has includes the subzones of the epipelagic, mesopelagic, bathypelagic, and abyssopelagic. Despite being home to many large predators though, many species use it to spawn, grow to maturity, feed, and breed. Slightly or majorly morphing in order to survive in your surroundings, adapting, is required for this ever-changing environment, and phytoplankton, sunfish, and flying fish have become adept at this skill.
A deceiving family name surrounds this organism, or animal. Even though it is called a fish, a glitter just above the surface of the ocean’s water might just be it. Admirably capable of swimming and flying, flying fish are pure evidence of how nature has learned to adapt. One adaptation they possess is an unequally split tail, for this gives them more control over movement. Flying Fish also have another trait that allows them to get airborne, expanded pelvic fins. However, not all species have these. Expanded pelvic fins allow more power to surge out of the water. Remarkably soaring into the sky, they take flight by slightly slanting upward toward the surface of the water, then, they lash their tail out at the water. Through decades of time, they have learned to obtain this flying method, another adaptation, as well. They can continue to fly for long periods of time by lashing their tails out at the surface whenever they get close. In fact, National Geographic states that, “. . .flying fish have been recorded stretching out their flights with consecutive glides spanning distances up to 1,312 feet (400 meters).” This allows them to cunningly escape underwater predators such as mackerel, tuna, and other fish.
Crucial to many food chains, surviving is not only critical for themselves, phytoplankton, it is also crucial to many other species. For though they are small, they have learned, overtime, to adapt. Minuscule in size, phytoplankton are configured in elaborate shapes. Their complex figures allow them to yield an excessive comparison in surface area-to-volume. Also generating an excessive frictional counter reaction, their shape benefits the brisk distribution of gas. Rapid excretion of waste, the ridding of unneeded and unhealthy things, over its build is also eased, along with light collection, and nutrient intake. A large surface area allows them to take in more sunlight so more photosynthesis can occur, thus giving them energy. Hasty...

Wolf Predations. This paper discusses four hypotheses to explain the effects of wolf predation on prey populations of large ungulates.

1731 words - 7 pages pit hypothesis assumes that predator losses are density-dependent at low prey densities, butinversely density-dependent at high prey densities. Van Ballenberghe (1985) states that wolf population regulation is neededwhen a caribou herd population declines and becomes trapped in a predator pit, wherein predators are able to prevent cariboupopulations from increasing.The final model that attempts to describe the effects of predation on prey

Similarly Wolf spiders (Pardosa milvina) are sometimes active hunters. “They can be idle predators that wait for prey to pass by, or they can actively hunt their prey”.

4222 words - 17 pages hiding from one's enemies(Alcock,1975). Predators are extremely sensitive to movement and locate their prey by visual cues. By getting rid of these key signals, enemies(predators) are forced to invest more time and energy looking for them. This may increase the time a prey has to live and reproduce(1975).Hiding is generally achieved through cryptic coloration and behavior(1975). How effective an organisms camouflage is depends on how long an organism

Nonetheless, large predators are capable of utilizing both large prey and small prey, while small predators are restricted to hunting smaller prey giving larger predators a “competitive advantage”. Through prey-size distribution, this advantage can be diminished allowing for their

The other exceptions could have abandoned this behavior due to the lack of prey fireflies in a particular habitat, or the dangers of drawing larger species of Photuris to prey on them.

Researchers at Cornell University in 1997 found that Photinus
