What would happen if the dolphins become endangered?
Transcript of What would happen if the dolphins become endangered?
To: The World
Dolphins eat a variety of fishes. Populations of dolphins eat squid, cod, herring, and mackerel
Everything in the world that is living has a cause and effect. If the dolphins became endangered what would happen to the rest of the ecosystem?
Food Chain Affect
There is a whole food chain affect if the dolphins were to become extinct
Dolphins are also endangered because of human developments and interaction with the ocean environment. These include:
Boats & Technology
The construction of dams
Man made platforms that isolated large river beds
Increased numbers of captive dolphins
A lack of food due to humans over hunting fish
Everyone needs to help protect the dolphins and their ecosystem!
Dolphins are top level predators that keep the entire ecosystem in place securely.
With lots of squid they will want to eat more shrimp, the less shrimp out in the ocean, than whales the oceans biggest creature will be left without food.
Since one of the favorite foods of dolphins is squid, there would be an overpopulation of squid
This is because whales feast on shrimp and krill and since there will be less shrimp, there will be less whales.
If fish and other aquatic species begin to over-populate they will consume other forms of food and prey at an extremely quick rate
Eventually they may end up eating their prey or to the point were their food would be unable to sustain itself causing the overpopulated fish to starve from a lack of sufficient food.
There are 36 types of dolphin across the world, including 4 types of river dolphin.
The larger dolphins sometime prey on turtles, seals, and sea lions.
Dolphins intake around 20 pounds of food each day
Dolphins can be found swimming in all of the worlds major oceans though most species tend to prefer living in warmer climates
In Taiji, Japan hunters slaughter thousands of dolphins each year.
By doing this they aren't balancing the reproducing levels of the dolphins. So the numbers of dolphins are slowly lowering away nearing endangerment levels. This could lead to an overpopulation of some fish.
What would happen to fish if dolphins were extinct...
In the end if dolphins became endangered or extinct it would effect the ecosystem in a harmful way
Dolphins should be treated fairly and not as something that is meant to be killed
All animals are precious; especially dolphins because they are known to be as smart as humans
