Jurassic Piranha Fossil is Earliest Flesh-Cutting Fish

The fossil of a piranha-like jurassic fish shows a flesh-slicing eating ability. The specimen was the first bony fish to have this capacity. Teeth were much like the South American piranha. However, the ancient creature lived in the ocean not in freshwater. People eat the piranha and say it tastes like other fish.

Zealandia is the New Continent

Continent of Zealandia near Australia..
There is something new in science, despite claims that everything is known.  New Zealand, like Australia (Australinea), is a continent - a very small one at that.  The scientific powers that be have to verify that it is the seventh continent. australia zealandia
Professor Bruce Luyendyk of australia named it Zealandia in 1995. Then, many claimed that it had only three of the necessary attributes. Satellite images show that the plate is unfragmented. With all four requirements identified, it is now accepted as a valid continent. The decision will be yes. Zealandia was part of Australia 85 million years ago. The land mass contains valuable minerals. Australia, New Zealand and New Caledonia will have to work out who controls specific areas. New Caledonia is a French overseas territory, so France will be involved. australia zealandia zealand continental million earth australia continents crust atlas zealandia stories continent people zealand today continental gallery million newest earth earth australia science continents size crust larger atlas zealandia landmass stories continent home people zealand horrifying today continental zealandia amazing gallery million continent understanding newest earth zealand reveal earth australia continental zealandia latest science continents million continent researchers size crust earth zealand field larger atlas continental magnetic landmass stories continents zealandia core home people crust continent heat horrifying today zealand planets amazing gallery ranking understanding newest habitability reveal earth slightly latest science land researchers size field larger microcontinents magnetic landmass fact core underwater heat gondwana planets antarctica ranking percent habitability idea slightly thickness land oceanic geologically microcontinents submerged fact credit underwater scientists gondwana eighth antarctica continent percent idea thickness oceanic geologically submerged credit scientists eighth continent.

Seasons and Ocean Distorts Australian Continent

The continent of Australia distorted by the seasons
continents are not static. They are pliable and change shape. In Australia it is called the continental wiggle. Ocean water moves in line with the seasons. It causes measurable deformation.
   continental earth seasons summer continent
Australian continent changes shape

The Earth is not a perfect sphere. It is lopsided. This disrupts the flow of the ocean. From April on, Australia is "pushed" to the east. This changes in October when it is pushed to the west and a bit to the north.
    shape continent seasons earth winter summer
Australia's measurement is determined by two satellites. It may be only millimeters but the Australian continent is moving. During the northern hemisphere winter, build up of snow and ice makes the Earth "top-heavy", which creates changes in the ocean.
  seasons distorted summer winter
The planet's center of mass moves to the South Pacific when the ice melts. Australia is in the middle of this see-saw effect, so it impacts more here than any other land mass.

Higher Carbon Dioxide Changes Behavior

Carbon dioxide changes behavor.
Higher carbon dioxide in the atmosphere could be making us stupid. Research has shown that greater concentrations of CO2 causes neurological impairment in fish. Sea water stores the dangerous element - the ocean has become more acidic because of its increased presence.
Damsel fish.
The test subjects were Damsel fish (Acathochromis polyacanthus), which live in coral reefs. Half were kept in a normal atmosphere. The other half were put in an atmosphere with elevated CO2.  Brain chemistry, blood and behavior were measured.

The behavior test involved the fish choosing between entering normal sea water or going to water containing injured fish. The smell of the injured fish should have stopped the damselfish from choosing to enter that water. However, the fish exposed to higher CO2  ignored or did not pick up the chemical warning: the injured fish didn't bother them.

This is ground breaking stuff. It could show what will happen to humans as carbon dioxide dramatically increases in coming years. People are not fish, but we are all animals. The process of preventing internal body tissues from becoming more acidic from a dangerous CO2 environment does cause chemical imbalance that affects behavior.

Weedy Seadragon (phyllopteryx taeniolatus) - Australiana

Weedy seadragon is an Aussie icon.
Weedy Seadragons (phyllopteryx taeniolatus) live only in southern Australian waters. The fish are quite large, growing to 46cm. They are redish with yellow spots and blend in with their surroundings.  Their red, sandy color does not show against the weedy background as they have green weed-like appendages.
Weedy Seadragon phyllopteryx taeniolatus
Seadragon males incubate eggs. A female puts about 200 eggs into a brooding pouch on the male during mating. The male fertilizes the eggs in his pouch. The young take two years to become mature.

When seadragons die they are preserved by bony plates. These can be found washed up on beaches. Yearly rings are "recorded" in their ear bones. They live for five years. Seadragons are a barometer for climate change. It the environment deteriorates many die off.

Red Reef Lobster Found in Western Australia

Biology: Red reef lobster caught in Western Australia.
It is common knowledge that lobsters do not have hair. We all know this. However, hairy lobsters do exist and one has been caught in Western Australia. The red reef lobster is common in the waters of Madagascar, Hawaii, and African countries. Finding it off WA is a real surprise.
Red reef lobster
The fisherman who caught it has never seen anything like it in his life. It seemed to be a prawn, lobster, scampi hybrid. The hairy red is much different from Australian lobsters: it has crab-like claws.

Biologists do not believe that it came all the way from Africa, at least not in recent times. They hold that it has been here all along living and breeding in a localized, remote spot. The one caught probably strayed away from its locality. Obviously, its normal range must be reasonably close. Being elusive, scientists are not going on a hunt. The creature will be left alone.

Big Raves About the Pegasus Helicopter Flotation Device

Technology:
It is surprising how people and government bodies live with a problem for decades when the answer is in front of their noses. Quite frequently rescue helicopter crash into the sea. There is usually a "ho-hum" - another helicopter has fallen from the sky.
Pegasus helicopter flotation device
Helicopters that can take off and land in the sea have been around for years. It is old technology. Obviously rescue organizations could have used them. However, they seem to feel that it best to reinvent the wheel. They plan to modify existing helicopters.

A self-inflating buoyancy balloon will be attached to standard helicopters. When a sensor detects water, automatic inflation will occur. Australian defence is throwing $4 million at the project. Marise Payne the Defence Minister is lauding it, saying "this is a fabulous innovation, by Australian minds, Australian brains, Australian workers...."  Let us hope it is not just a silly idea!rafdevice
