Te Papa has a new colossal squid!

Watch live online as specialists in squid biology from Te Papa and Auckland University of Technology undertake research on this rare find. This colossal squid and the specimen already on display at Te Papa are the only two of their kind caught intact – ever! Large colossal squid specimens in good condition are rarely available to scientists, so this latest example has caused great excitement.

Elusive giant squid found in fishing net off the coast of Japan

Monday 13 Jan 2014 12:10 pm

It’s usually one of the mysteries of the deep – but an elusive giant squid has been found in a fishing net off the coast of Japan.

The 4m (12ft) beast was found by fisherman Shigenori Goto swimming in one of his fixed nets about 70m underwater off the coast of Sadogashima island.

After it was brought to the surface, the squid – later found to be male – died.

‘This is the first time I’ve seen such a large squid,’ Mr Goto told reporters in Japan.

The giant squid was taken to a local government marine research institute in Niigata for research.

Giant squids are rarely seen because of the depths at which they live.

The first footage of a live adult was not taken until 2002 and the largest one recorded by scientists was almost 43 feet long.

A recently reported sighting of one in California proved to be a hoax.

What a beached whale ate, new research


This video is called Northern Bottlenose Whale Species Identification.

In 1956, a female northern bottlenose whale beached near Oudeschild village on Texel island in the Netherlands.

Recently, the contents of its intestines were investigated at Ecomare museum on Texel.

Arthur Oosterbaan of the museum investigated squid bills.

This is called A close-up video of Boreo Atlantic Armhook Squid, Gonatus fabricii in the deep waters of the Canada Basin.

Most were bills of the Boreo Atlantic armhook squid (Gonatus fabricii).

The others were Gonatus steenstrupi, a bit more southern species.

A pod of five sperm whales sighted inshore off North West Scotland

Giants of the sea enjoy Scotland’s warming waters

February 2013. An extraordinary winter sighting of five Sperm whales off the coast of North West Scotland this week could be a reflection of climate change and warming sea temperatures, says a leading marine scientist.

The Sperm whales – one of the true giants of the oceans – were first seen by creel fishermen between Loch Torridon and South Rona on Monday. They initially thought they were Humpback whales and alerted boat operator Nick Davies from Hebridean Whale Cruises, based at Gairloch, who is involved in a project collecting cetacean (whale, dolphin and porpoise) data for Sea Watch.

First sighting

He went out to the location, and when he arrived was astonished to recognise Sperm whales diving together for food – the first time he has ever seen them.

Dr Peter Evans, director of marine conservation research charity Sea Watch, was able to confirm the sighting from his photographs and says: ” In past decades, most records of Sperm whales in British waters have been of lone adult males around Scotland mainly off the Northern Isles and the Hebrides. Increasingly, however, adolescent males have occurred in our waters, sometimes in groups of 5-10 individuals.

Inshore

“Sightings of groups of Sperm whales have tended to occur mainly in summer so this winter sighting of a group is notable not just for the time of year but for its inshore location. The species normally lives in waters of 1,000 metres or more depth, beyond the continental shelf edge. Here they have sought out the deepest area of NW Scotland – the Inner Sound.”

“The increased occurrence of winter sightings in Scottish waters could be a reflection of climate change, with their main prey, squid, becoming more abundant locally in recent years, resulting in animals staying through the winter to feed rather than travelling into lower warmer latitudes.”

Sperm whales

Sperm whales are amongst the largest mammal species in the world. Adult males can weigh in at up to 45 tonnes – the iconic London Routemaster double decker bus weighs less than 8 tons, unladen!

Nick Davies explains: “I was excited at the prospect of Humpback whales, but never expected to see Sperm whales.

“When I was about 8-9 miles away I could see their spouts – it looked like a flotilla of yachts and as I got nearer it was obvious from their flukes (tails), that they were Sperm whales. There was one enormous animal and four smaller ones, and they were synchronised diving, going down for 30 minutes or so at a time.

“Fishermen have been telling me that for the past four or five years they have been seeing increasing amounts of squid in their nets, and it seems that this was perfect for the Sperm whale.”

The sightings, made on Monday February 18th were in waters one mile east of Caol Rona in the Inner Sound between the islands of Rona and Raasay – close to an area where the in-shore waters are at their deepest at 1,000 ft.

Sperm whale ID

Sea Watch is now analysing Nick’s photographs to see if they can be match the tail fluke markings in the trailing edge to any individuals included in a North Atlantic catalogue of individuals photographed from locations as far apart as the Azores and Madeira to Iceland and Norway. Matching of individuals between locations gives us a better idea of the movements of this wide-ranging species. Individuals have already been matched between the Azores and Norway (Andenes and Tromsø). And in 1997, a photo image from Andenes matched a male stranded on the west coast of Ireland.

According to Sea Watch’s national database, there have been just 94 separate sightings in British waters since 1974, with the largest group on record being of 20 animals seen off Mousa in the Shetland Islands in 2007.

Sperm whale facts

Length: Newborn calves are 3.5-4.0m long. Adult females are 8.3-11.0(15.0)m 27.4- 36.3(49.5)ft and can weigh up to 14 tons. Males grow to around 11.0-15.8(20.5) m / 36.3-52.1(67.6) ft (adult male) and can weigh 35-45 tonnes.
Head: The sperm whale has a huge square head (up to one-third total length in male), and under-slung lower jaw.
Fin and Markings: No fin but distinct triangular or dorsal hump two-thirds along body, followed by spinal ridge. Corrugations on skin gives the sperm whale a shrivelled appearance. Dark brown or grey in colour.
ID: The bushy blow of a sperm whale is directed forwards and to left – 1.5-5.0m high; the species may lie log-like on the surface; broad, triangular and deeply notched tail flukes thrown into air.
Lives: up to 70 years.
Feeds: on squid, octopus and other fish.
