Great Barrier Reef Mindmap
Location
The Great Barrier Reef is located at the coordinates of Latitude 18° 9' 22.6440'' S, Longitude 147° 29' 9.4632'' E
The Great Barrier Reef is located off the coast of Queensland, Australia in the Coral Sea.
The Great Barrier Reef, is, well a coral reef.
Climate
Water temperature in the reef goes from 24° C in the winter to 30° C in the summer.
The reef is affected by two main currents: the East Australian Current and the Trade Wind Drift Current.
Threats
Abiotic
Low-frequency underwater noise pollution can affect the effectiveness of Bryde's Whales' hunting and communicating.
Oil spills and the cleanup afterwards can poison ocean animals, including whales and by definition, Bryde's Whales.
Biotic
Bryde's Whales have recently become a hot target for whalers from Indonesia and the Philippines. Japan's scientific research whaling program is also a factor in the hunting of Bryde's Whales.
Bryde's Whales can get caught in fishing equipment.
Predators and Prey
Predators
Sharks
Killer Whales
Actually, there are not many predators big enough to kill a Bryde's whale. Presumably, only a killer whale would be big enough and voracious enough to devour a Bryde's Whale. There are no clear discernable predators of the Bryde's whale.
Prey
Schooling Fish
Mackerel
Sardines
Anchovies
Herring
Pilchards
Crustaceans
Small crabs
Pelagic red crabs
Krill
Prawns
Copepods
Adaptations
Structural
All whales have a streamlined body that lets them glide in the water.
Tail fins are horizontally placed to allow for powerful up and down movements.
Forelimbs turned into steering devices as whales evolved to swim.
Behavioural
Whales emit low pitched sounds to communicate at long distances. (hey vsauce michael here) Because low frequency sound waves have a large wavelength, they can travel very far in air, and even further in water - up to 10000 miles in the best conditions.
Whales can swim up to 48km/h when neccesary.
Whales use their lungs as ballast tanks.
Functional
Hair is replaced with sub-skin blubber for warmth and buoyancy.
Reproductive organs are internalized to prevent drag.
Whales breath through their blowholes, expelling up to 90% of stale air from their lungs.
Whale tails are made entirely of hard cartilage, preventing loss of mobility.
Whales have muscle with a high level of myoglobin, for strength.
