Friday Squid Blogging: Giant Squid in Tasmania

In 2002, a 60-foot long giant squid washed up on the beach in Tasmania.

Because of the low number of observations, scientists have struggled to build up a profile of the giant squid, discovering only in the last five years how it reproduces.

It is believed they rarely have an opportunity to mate, and live isolated lives, but it is still unknown where the squid fits on the food chain.

The giant squid is a carnivorous mollusk with a beak-like mouth strong enough to cut through a steel cable and its eyes are the largest in the animal kingdom—growing up to 45 centimeters (18 inches) wide.

The giant squid is believed to feed on, among other things, the world’s biggest animals with several eyewitness stories from fisherman who have seen the squid in fierce battles with whales.

Dead whales have been found washed up on beaches with large sucker marks on their bodies, apparently from squid attacks.

Friday Squid Blogging

It’s from last September, but it’s the biggest giant squid news in years—a live giant squid caught on camera:

In their efforts to photograph the huge cephalopod, Tsunemi Kubodera and Kyoichi Mori have been using a camera and depth recorder attached to a long-line, which they lower into the sea from their research vessel.

Below the camera, they suspend a weighted jig—a set of ganged hooks to snag the squid—along with a single Japanese common squid as bait and an odour lure consisting of chopped-up shrimps.

At 0915 local time on 30 September 2004, they struck lucky. At a depth close to 1km in waters off Japan’s Ogasawara Islands, an 8m-long Architeuthis wrapped its long tentacles around the bait, snagging one of them on the jig.

Kubodera and Mori took more than 550 images of the giant squid as it made repeated attempts to detach itself.

The pictures show the squid spreading its arms, enveloping the long-line and swimming away in its efforts to struggle free.

Finally, four hours and 13 minutes after it was first snagged, the attached tentacle broke off, allowing the squid to escape. The researchers retrieved a 5.5m portion with the line.

A squid that cares for its young:

But a team of ocean scientists exploring the inky depths of the Monterey Canyon off California has discovered that at least one squid species cares for its young with loving attention, the mother cradling the eggs in her arms for months, waving her tentacles to bathe the eggs in fresh seawater. The scientists suspect that other species are doting parents, too, and that misperceptions about squid behavior have arisen because the deep is so poorly explored.

“Our finding is unexpected because this behavior differs from the reproductive habits of all other known squid species,” the scientists wrote in the Dec. 15 issue of Nature. “We expect it to be found in other squids.”
