MOVEMENT IN THE OCEAN TYLER KAINE To explain how many different
words can be used to describe movement I would like to talk about a
strong interest of mine MARINE LIFE In the ocean, there are
countless species that rely upon agility and overall speed to
maintain survival. For example, certain types of sharks need to be
progressing forward at all times in order to stay alive. The
complexion of their body and most specifically their gills, rely on
the constant flow of water into their gills to help oxygenate their
blood. Once they stop moving they are not allowing the water to
flow through their gills, which kind of resembles a human holding
their breath. So for these sharks, such as the great white shark,
movement is a crucial part of their existence, without it they
would not be here. Considering sharks do not have excellent eye
sight they need to rely upon movement with the help of their extra
sense called electroreception (Cogner). Sharks and many other types
of marine animals can emit an electrical field or currents to
detect how close their next meal is or how close a predator might
be. By being able to send out these fields they can detect where
they should move to or relocate to find their prey or stay far away
from being attacked themselves. Next, in terms of the consumption
of food, certain oceanic species need to rely on strategic movement
when they go seek prey. For example, moray eels are ambush
predators. These eels like to hide in the crevices of ocean rock
and wait stationary until they see prey in sight. Once they lock in
on a target they protrude out and propel towards the prey. By not
revealing any movement until needed, they can successfully feed
themselves and survive. However, swordfish use their quick speeds
to capture their prey. Contrary to popular belief, swordfish do not
actually spear their prey with their sword like bill, they quickly
swim up to the prey and thrash and slash their prey until it can no
longer put up a fight. The swordfish relies on these quick erratic
movements and their quick speed to be able to survive. At the end
of the day it does not matter how different species of marine life
utilize their ability to move, it is just important that they are
able to manipulate this simple idea into many different strategies
and techniques that help them live another day. MOV- to move PUL-
