Dolphins Are Important Too

Effects of pollution on Dolphins


  • Dolphins are found worldwide, in the continental shelves mostly or shallow tropical parts of the sea.
  • These wonederful animals are carnivores. Their diet consist of mostly fish and squid.
  • Dolphin coloration varies, but they are generally gray in color with darker backs than the rest of their bodies.
  • They are in the the family of toothed whales.
  • They are mammals.
  • They are agile and very playful. In their pods they are a tight knit family.
  • Dolphins use echolocation to navigate and hunt, bouncing high-pitched sounds off of objects, and listening for the echo.

How is pollution affecting one of the smartest mammals?

Dolphins! Highly intellignet, gentle, & talented marine animals that mostly everyone knows of and loves, yet there are some things that cause these beautiful animals to have a down fall in population and decline in health, pollution. Pollution has been around for centuries and whether intention or unintentional it effects every animal out there in the wild life.

How pollution effects these creatures.

Green houses, littering, and pollution from human carelessness affects every square mile of the ocean. Forty percent of marine ecosystems ((community of interacting organisms and their physical environment)) are suffering the consequences of pollution; their food sources and habitats included (( Pollution has such a large influence on dolphins; pollution jepoardizes their wellbeing, and over all health. Chemical spills, Oil spils, conducting loud military exercises at sea, and increases in boat traffic can all put whales and dolphins in danger, cause them to strand on coastlines. In certain cases it can even kill them.
Ocean Pollution - Save Our Marine Life

Noise Pollution

Believe it or not but the oceans have been filled with sounds from natural sources for tons of years. Squeaks, moans and clicks of whales and dolphins, the sound caused by wind and even the occasional rumble from earthquakes. Gradualism evoled the oceans into what they are today. Dolphins and creatures of their kind have their own hearing abilities, communication skills and echo abilities at natural sound levels. Hearing is as important to dolphins as sight is for humans. They can use this talent of theirs to warn others of potential dangers. Man-made sounds like army testing and drilling for certain things under the sea is drowning out the calls of mates, calves and other pods that these animals depend on. These noises can even prevent dolphins and whales to be thrown off their migration paths, leaving them seperated from their pods and family.

Oil and Chemical Spills

When dolphins surface to breathe, oil contaminated water can cover their blowholes and enter their lungs, making breathing much more difficult. Oil can get into dolphin's eyes, risking damage to vision. The oil can also enter their mouths, where it can be ingested, having a very high risk of damaging internal organs. Oil contamination will have negative effects on reproduction and the wellbeing of not only dolphins but all other marine life.
