Not Your Average Holiday BBQ

Diners at the Iberostar Hotel in Tunisia select their own cut to be cooked by the chef.

[I have no information on the circumstances of this catch, if it was accidental or targeted etc. It appears to be a thresher shark which are considered a vulnerable species* by the ICUN, but hey if it’s dead already may as well eat it? (Representatives for the hotel have since stated it was a one-off event, now never to be repeated). Hopefully it was at least a learning experience for those who tried a piece, forcing them to have a conversation they may never have considered about sharks.]

*A vulnerable species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as likely to become endangered unless the circumstances threatening its survival and reproduction improve. So, pretty much every commercial catch ever.

A sea turtle provides a modicum of shelter for baitfish attempting to evade the eyes of hungry sailfish.


Inside the mouth of a Leatherback Turtle, the largest turtle in the world. The ‘spikes’ are actually soft and fleshy and help the turtle in swallowing its main prey- jellyfish.
For an amazingly in-depth look at this weird feeding apparatus, check out the fab docco series Inside Nature’s Giants (skip to 20.25 for the digestive system part).

This marlin bit off more than it could chew off the coast of Angola. This is the floating load hose on the FPSO Girassol; the marlin caused the loading operation to shut down for a few days while the hose was replaced. The loading hose is approximately 24″ in diameter and the terminal produces about 250k barrels of oil a day.

Ever tried cutting through a car tyre? Try to imagine the immense turn of speed this fish had to work up in order to bury itself up to the hilt in material may times a tyre’s density and thickness! Sadly the marlin was not able to be released alive as it was too firmly lodged in place. The marlin was cut from its bill, which was still not able to be dislodged, and the entire section of hose was removed.

A New Zealand kayaker prayed for his life as a giant crocodile he  feared would devour him at any moment kept him hostage on a remote  Australian island.

Ryan Blair had an amazing escape after he was  trapped by the massive crocodile on the Governor Islands in the Timor  Sea off the northern tip of Western Australia for more than two weeks.

The  37-year-old had been exploring the WA coast near Kalumburu, between  Derby and Kununurra when he ended up stranded at the twin islands of  East and West Governor, the biggest of which, West, is just 260  hectares. The nearest settlement is Kalumburu, about 40 kilometres  south.

Once alone, the Kiwi realised he didn’t have enough supplies and tried to paddle the four kilometres to the mainland.

But he immediately caught the eye of a six-metre saltwater crocodile that’s lived in the area for years. Every  time he tried to leave, the crocodile would stalk Mr Blair, leaving the  adventurer fearing for his life and stranded for more than a fortnight.

”He was about four metres away from me and I thought ‘this is it’,”’ Mr Blair said. ”It was so close, and if this croc wanted to take me it would not have been an issue. I was scared for my life – I was hard-core praying for God to save me.”

On  Saturday, local Don MacLeod spotted a light on the island, and when he  checked it out, the hatless, shirtless and desperate visitor approached.

”He  was relieved and shocked, and thankful someone had come along because  he was running out of options pretty quickly,” Mr MacLeod told ABC  radio. ”He is a very, very lucky man.”

Ryan’s passage to WA was not easy in itself. He  travelled from Queensland on a yacht whose owner was jailed in the  Northern Territory, leaving Mr Blair stranded for two months. After  hitching a lift with a solo yachtsman from the Territory to WA, he was  dropped on Governor Island with 160 litres of water, some flour and dry  stores.

But after realising he was unprepared for the Kimberley  wilderness, three attempts to reach the mainland were thwarted by the  crocodile.

Mr MacLeod said the story was incredible. ”He  said every time he got in his little kayak, which was only 2.5m long,  this crocodile – who has lived there for many years and is a monster –  has chased him,” Mr MacLeod said.

”He was desperate for water when I trotted up. We gave him a cold beer, which was probably the wrong thing, and then he went to sleep about three-quarters of the way home.”

Mr Blair flew out of Kalumburu to Kununurra on Monday, and said he had seen enough of Australia’s outback- ”For the moment I can have a bit of a break from the adventuring days,” Mr Blair said.

This picture blew my mind a little when I first saw it a few years ago. I’ve never been very good at visualising weights but with the guy in the photo for reference the sheer size some tuna can reach was seriously brought home to me! If I remember correctly these fish were caught off ?New England with the larger of the two (I think its a Bluefin) weighing in at around 500lb.
Check out the groove down its side- the pectoral fins recess along it and lie completely flat to the body for ultimate streamlining.


Look at the size of those operculums! LOOK AT THEM! Those gills have to be massive to keep a fish that big adequately powered at high speed.
