Great White Shark Adaptations
Transcript of Great White Shark Adaptations
Adaptation and Variation
A volcano has erupted in the ocean causing pH levels to fall and the turbidity rising, and also the acid rate. Also volcanic ash has polluted some parts of the ocean. It kills its natural prey (fish), and destroys its natural habitat (sea caves)
The changes in the shark's environment shows natural selection because the sharks with these traits in the environment with the natural disaster will survive. The ones without these specific traits won't. The only sharks that will survive are the ones most fitted for this type of situation. As the more un-fit sharks die, the more fit sharks will reproduce. And the allele frequency will go up as they reproduce more.
Great White Shark
Scientific name of organism: Carcharadon Carcharias
Region: Indian/Pacific Islands
Abiotic Factors: water
Biotic Factors: sea plants, coral reefs, fish, tuna, dolphins, turtles, crabs, lobster
Amount of water availability: 100%
Amount of light: high when close to surface and low when at the bottom of the sea
Foods: Fish, people, trash, other sharks
How does it get food? It hunts for food
Symbiotic relationship: Predation
Shelter: Caves and Sea Plants
The eyes of the shark help the shark to see and track their prey in the water.
The dorsal fin helps the shark to move swiftly through the water.
The gills of the shark normally just filter out the contents of the water to get oxygen.
The shark's skin acts as camouflage and helps the shark to go unseen while hunting.
Lorenzini sensory system will grow more attentive to movement.
Sharks will grow a second dorsal fin
The sharks gills will filter volcanic ash and other content from the volcano in addition to the contents of the water.
Sharks will grow a darker coat of skin to blend in with the water.
Due to all of the volcanic ash in the water the shark has to rely on it's lorenzini sensory system instead of it's eyes to hunt for prey.
due to the increased density of the water from all the volcanic ash, sharks will have to grow an extra dorsal fin to move faster through the water.
Sharks will grow an extra gill, just like sharks in the jurassic period, in order to filter volcanic ash.
They will get a darker coat to blend in with the water and catch their prey easier.
