For today's Geo Quiz we're swimming with sharks.
Australian conservationists warn that sharks in the waters off Queensland could soon be wiped out.
These are mostly white tip, silver tip and grey reef sharks. And they swim in the sea whose name we're after for our quiz.
To the west, the sea is bounded by Queensland and to the east, by the New Hebrides and New Caledonia islands.
To the south is the Tasman Sea.
To follow the sharks, marine biologist Richard Fitzpatrick used satellite tagging:
"The species we're doing research on here are threatened throughout most of the Indo-Pacific region, mainly due to fishing for the shark fins, and the populations are being decimated."
Researchers with the World Wildlife Fund say this sea off Queensland is one of the last marine wilderness areas on the planet....they want to protect the sharks here by declaring it a marine protected area.
In the meantime -- we want you to locate this sea on a map and name it.
