Rare, elusive marine
fish observed
MONTEREY,
Calif., Aug. 28 (UPI) -- U.S. marine scientists say they've captured the
first-ever video of a rare anglerfish first identified from a dead specimen in
1891 but never seen alive. Researchers at the Monterey Bay Aquarium Research
Institute in California are reporting the first observations of the deep-sea
anglerfish Chaunacops coloratus using remotely operated undersea vehicles. All
anglerfish have ability to attract prey, using parts of their bodies as lures. During
one ROV dive, the researchers said, they observed C. coloratus deploying a
shaggy, mop-like lure, called an esca, which it dangled from the end of a
modified fin near the top of its head.

Triassic amber yields
'ancient mites'
By Jonathan Ball BBC News
Some of the earliest fossils of pre-historic arthropods -
dating to about 230 million years ago - have been discovered entombed in amber,
PNAS journal reports.
Arthropods - a highly diverse family of invertebrates, which
includes insects, arachnids and crustacea - constitute more than 90% of the
entire species within the animal kingdom.The previous earliest records of
arthropod-containing amber dated back to the Cretaceous period, around 135
million years ago.The researchers hope that the recent find - of two
plant-feeding mites and one insect - will provide important insight into the
early evolution of this highly diverse family of animals.Amber is fossilised
plant resin. The resin often entraps plant and animal material which then
become buried - as "inclusions" - when the fossil amber forms.
