Here is an article that may be of some inspiration for background for
some of those Auazone type FT Scenarios. Although it could be useful in
an Aquazone DS 2 or even SG 2 scenario too!

Weird ocean life surprises
By Dr David Whitehouse
BBC News Online science editor
New species of underwater life, including a giant sea
spider
and armoured shrimps, have been discovered by a
expedition
trawling in deep water northwest of New Zealand.
Researchers on a joint NZ and
Australian voyage also found
deep-sea sponges and a prickly
shark.
The scientists have just returned
from four weeks aboard the
Research Vessel Tangaroa
collecting and photographing
species at depths up to 2.1
kilometres (1.3 miles).
According to Mark Norman, of Victoria Museum in
Australia, the
survey around Lord Howe and Norfolk Islands was the
most
complex research expedition ever conducted in
Australasia.
"Many species new to science were recognised, including
new
sharks and rays, redfish, rattails, and a range of
invertebrates,"
he says.
Each way bet
One newly discovered creature,
called the fangtooth, has teeth
longer than its head. To avoid
piercing its own brain when it
shuts its mouth, its teeth fit into
opposing sockets.
The so-called viperfish has a
hinged head and the coffinfish
walks along the sea floor on
short leg-like fins with a glowing
lure on its head to attract prey.
They also found two rare spiked dogfish, a small type
of
shark,
doubling the number of known specimens.
One of the strangest creatures was a Pacific spookfish
which has
a long snout that probes for electrical signals from
its
prey.
There was also a squid,
nicknamed the wonky-eyed jewel
squid, which has a left eye much
larger than its right eye. It seems
that the big eye looks up for food
while the small eye looks down
for predators.
The spiders found on the sea
floor are not related to terrestrial
spiders. They have such small
bodies that some of their internal
organs are pushed down inside
their hollow legs.
Work starts here
The strange characteristics of the new lifeforms are
adaptations
to conditions beneath kilometres of water where the
pressure is
hundreds of times greater than at the surface; and it
is
also
completely dark.
The researchers also found a huge fossilised tooth of
an
extinct
shark known as a megalodon. The tooth had been lying
undisturbed on the sea floor for millions of years.
In total, 500 species of fish and 1,300 of
invertebrates
were
discovered. It will take over a year to classify them
all.
"We are only just beginning to
understand our marine
environment and voyages like
this help us fill in pieces of the
puzzle," says Australia's National
Oceans Office deputy director
Sean Sullivan.
"Scientists know roughly as much
about Australia's ocean
environments as we did about
the Australian land 150 years
ago."
The month-long on the RV Tangaroa also found extinct
volcanoes
as they mapped the ocean floor during the
10,000-kilometre
(6,200 miles) voyage.
