BIg fish found and new discoveries in the Ocean

Biologists fear 'giant' goldfish will alter Lake Tahoe
RENO -- Biologists are worried that Lake Tahoe's pristine blue water may be affected by a "giant" visitor.Goldfish have inhabited the water of the Tahoe Keys since the 1990s, said Sudeep Chandra, a biologist at the University of Nevada, Reno.But it wasn't until 2011 that biologists found a 14.2 inch, 3.4 pound goldfish in the lake. More "giant" goldfish have been found since, he said.It is not entirely known how the goldfish are being introduced to Lake Tahoe. Chandra said he thinks people who have goldfish as pets are disposing of them in the lake.
Plenty of food for Tahoe Tessie the lake creature then .

Deepest undersea vents discovered by UK team
UK scientists exploring the ocean floor in the Caribbean have discovered an "astounding" set of hydrothermal vents, the deepest anywhere in the world.Deploying a remotely-operated vehicle (ROV) in the Cayman Trough, they stumbled across a previously-unknown site nearly 5000m below the surface. Video pictures relayed live back to the research ship mounting the operation show spindly chimneys up to 10m high.They are belching out dark water - "a stunning sight", one scientist said.In the immense pressure of the sea three miles down, the ROV, known as ISIS, was gently steered around the vents, taking pictures and gathering samples.
They may find more new species.
