- Ahli Temukan 'Dunia Hilang' di Laut Antartika
Alasan keberadaan mereka sangat menakjubkan mengingat adanya gunung api bawah laut yang sering menyemburkan asap hitam yang dapat membuat suhu naik 380C. Suhu seperti ini bisa melelehkan timah.
Pemimpin riset, Profesor Alex Rogers dari University of Oxford, mengatakan seperti dikutip DM,
“Kami menemukan komunitas organisme yang belum pernah ditemukan di Bumi sedang berjuang hidup”. Hasil studi ini diterbitkan di jurnal PLoS Biology.
Mysteries of the deep: Anemones and barnacles near a hydrothermal vent 8,000 feet down near the East Scotia Ridge in Antarctica
On
the shelf: Sea anemones and barnacles flourish in complete darkness,
drawing energy from breaking down highly toxic chemicals found in the
smoke
Octopus's garden: The team found what they believe is a completely new species of the creature in the ocean's depths
Claws
for thought: Another of the two dozen new species found was a
16cm-long 'yeti crab', which was piled in huge heaps of up to 600 near
the vents
Cooked crab: Some of the creatures had gone so close to the vents that they had visible burn marks on their shells
The
creatures were found on top of undersea volcanoes called hydrothermal
vents, which pump out plumes of black smoke causing temperatures to
rise to 380C - hot enough to melt lead
Although
temperatures are boiling immediately around the vent, they cool to
around 20C a few hundred metres away. This is where the sea creatures
congregate
Searchlight: The eight-week mission unearthed many new species using a deep sea rover controlled from a nearby vessel
