Fishermen
off Australia who accidentally caught a whopping basking shark have provided
scientists with a rare opportunity to study the second-biggest fish on the
planet.
The 6.3
metre (20 feet) fish is causing a sensation Down Under where little is known
about the species -- smaller only than the whale shark -- as it is not often
captured in southern hemisphere waters.
The rare
specimen has been donated to Museum Victoria, in the southern city of
Melbourne, where scientists plan to use the body to research the shark's
genetics, diet and life history.
The museum
-- which currently has only three samples from basking sharks, all over 80
years old -- said Wednesday it also plans to use the head and fins to build a
full-scale exhibition model.
"These
rare encounters can provide many of the missing pieces of knowledge that help
broader conservation and biological research," said the museum's senior
curator of ichthyology, Martin Gomon.
Basking
sharks are slow-moving plankton feeders which can grow up to 12 metres long.
Unlike other sharks, their teeth are tiny -- about two millimetres long -- and
they feed by trapping tiny plankton and jellyfish in their huge mouth, the
museum said.
They are
migratory and widely distributed, but only regularly seen in a few favoured
coastal locations such as such as Cornwall in England as they can dive deep
into the depths of the sea in search of food.

The shark
was accidentally picked up by a fishing trawler in the Bass Strait off the
Australian mainland's southeast.
Museum
Victoria's senior collection manager of vertebrate zoology, Dianne Bray, said
basking sharks had been sighted over the years off Australia's Victoria state,
but never in large numbers.
"They
are rare in southern waters, but not that rare in northern waters," she
said. "We have no idea of what their numbers may be."
Bray she
had been inundated with requests for tissue and other samples from around the
world as opportunities to study an entire animal were rare.
