On our recent expedition to Guadalupe Island, we had a couple of talented amateur photographers on board. Kyle and Tiffany Chapman. They documented their “real shark week” with these pictures, all taken with a Gopro!As you can see, the sharks have been…
We just finished our second trip and the action continued, where it left off on the last trip. A lot of familiar faces are back at Guadalupe. Our boys, Don Julian, Horizon, Kenric, Geoff Nuttall Mike, Drogin Thor and Micks are all back and Lamini, a little female from last season was also around. We counted a total of 15 named sharks, along with 4 new ones and a few we haven’t identified yet.
There seems to be a lot of fighting going on at Guadalupe right now. Many sharks are sporting brand new bite marks. I saw Horizon take a big chunk out of a bigger sharks head, which is very unusual, since the hierarchy is usually established based on size. (we haven’t identified the bigger shark yet) Chuggy, who we talked about last season, having recovered from a nasty bite to his head, came by with some very fresh bite marks on his face. The big gash from 2 seasons ago, is now just visible as a black scar.
With all that fighting going on, I hope that those idiots who dive outside the cages, thinking the sharks are accepting them as one of their own, are wrong. I have seen, what those sharks do to smaller sharks and those guys would indeed be very, very small sharks.
Oh, did I mention that the sharks got close?
We are just about to board another group of divers. I will update you on our season, when we get back in 5 days.

We just came back from our first expedition to Guadalupe Island. It was, what can I say, phenomenal!. We saw over 20 different sharks, with both familiar and new faces. I’m happy to say that Jacques, Bite Face, Johnny, Thor, Squire, Gunther and #148 are all back, safe and sound.

| Jacques and Criss Cross |
Criss Cross, who we haven’t seen in a few years also showed up, missing a big chunk of flesh, in the right pelvic area, but the injury seems fully healed. These sharks seem to have a rough live, but their healing ability is absolutely remarkable.

After a flat calm crossing to the Island, the action was non stop on day one. Bite Face and Gunther competing for who can his picture taken more often. One diver ended up taking 7000 pictures in one day!!!
Gunther also showed a new and unusual behavior for a white shark. He came up to the cage, very slowly and proceeded to bite the cage in various places. He was going in slow motion and though it didn’t seem to be a predatory kind of biting, it is just another reminder, that it is definitely a good thing to stay inside the cages, despite what any “expert” says to the contrary.

| Think being outside is a good idea? |
On day two the action didn’t slow down. It actually got even better. We lost count at 13 different sharks, at least four of them being new individuals, that have not been added to our photo id database.
On our last day, the sharks gave us an unbelievable send off. At least 10 individuals came by to say goodbye to our divers.
We only have a couple of hours, before we leave again on our second “real shark week”. I can’t wait to be back down there and introducing a new group of divers to these magnificent creatures.

Yesterday, we sold the last spaces for this years Great White Shark expeditions to Guadalupe Island.It didn’t take long for our phones to ring, with divers asking us to add another trip to our schedule. So we decided to run another expedition from Nove…
Not only does shark week sensationalize sharks. Now in their effort to “educate” people, they ask this.I knew that the stripes can fade, but looking like a White Shark? Lets see, is this a tiger shark or a white shark below?What am I? Tiger or White Sh…
Our Great White Shark season is starting in a couple of weeks. This is going to be my 14th year, visiting Guadalupe Island and believe it or not, I’m getting more excited to go back each year. I just can’t wait to see who’s back. Is “Shredder” going to…
The Australian EPA is doing a Public Environmental Review (PER) and is soliciting comments from the public. This is our chance to be heard, but please consider a few things, before you write your response.
As usual, “DaShark” has beat me to it and written an excellent blog on the subject. Here are a couple of things he mentions.
During the first period of public review, here is what happened.
The 14 week trial attracted intense media and community interest.
The trial generated:
- 765 separate articles on sharks in local, state and national newspapers
- 1,100 radio news bulletins on sharks (Western Australia)
- 850 radio talk back comments on sharks (Western Australia)
- 290 television news items on sharks (Western Australia)
- 286,000 emails and letters to the Department of the Premier and Cabinet (DPC) – a significant number of which were pro forma emails
- and a significant number of postings on Twitter and Facebook, some of which were offensive and contained personal attacks on members of the Government and staff involved with the program.
So basically, they blame us for why, what they claim is the silent majority, has stayed quiet on the subject. They are not kidding, that’s what they believe. If we want them to listen to us, we have to mind what we say and how we say it.
Here is DaShark’s advice.

Yesterday we talked about the international headlines of “Great white shark being eaten by sea monster”.
Here is a response by CISRO, the organization who placed the tag on the shark in question.
When we looked at its data there was a period of approximately three weeks just before the tag surfaced where the temperature recorded was higher than the surrounding sea, but where the tag continued to ‘dive’ in a pattern consistent with a white shark. During this time, the tag failed to record light. Data before and after suggest the tag was functioning normally. The temperature recorded for these three weeks was consistent with that of the core body temperature of a white shark but too low for something like a killer whale.
They go on to explain, what they think had happened.
At one point the shark that had eaten the tag dived to a depth of 570 m – this is not unusual for white sharks – it is normal behaviour. This dive took place about one week prior to the tag recording the higher temperatures (not immediately before as some have reported) and the two events are not related.
All evidence suggests that the tag had been eaten by another white shark. We have seen white sharks biting each other before, sometimes removing pieces of tissue in the process. We concluded that this was the most likely explanation – One shark bit off a little more than he could chew and ended up swallowing the tag.
We never concluded that the 3m shark was consumed by another much larger shark.
Yesterday I questioned the “scientists” conclusion, that a sea monster ate the shark. Now we know that there were not even any scientists that concluded that, it was simply the filmmaker ignoring what the group who placed the tag in the first place had to say. Now that’s something you’d expect from a Sci Fi channel production, not a Smithsonian “documentary”!

The story that a tagged great white shark has been eaten by another great white shark is making headlines around the world. Various news outlets like UPI are reporting that “Australian scientists are searching for a “mystery sea monster” that likely devoured a nine-foot-long great white shark they’d been tracking.” and People magazine is saying it was a “colossal cannibal great white shark” and even stating that it’s size is “estimated at 16 feet long and over 2 tons”
Wow, that is amazing! They not only know that this shark has been killed, they also know what killed it and even estimate the size of the killer. How the heck did they do that? Estimate the size and species of a predator by the temperature of a tag. And here I was, finding it incredible that another guy claims to be able to do that by the shape of a dorsal fin.
So let’s look at a few facts. The great white sharks do indeed maintain a body temperature of a few degrees above the water temperature. According to Elasmo-research.org, great white sharks maintain a muscle temperature of 7-9 degrees f, and a stomach temperature of 13-25 degrees f above water temperature. The scientists claim that the tag could not have fallen off, because it would have recorded a lower temperature first, before the jump to the higher temperature, after it was eaten. So if that were true, that would put the maximum temperature inside a great white shark stomach at 64 degrees and not 78.
Since the tags we are talking about here, are external, they record the temperature of the water and not that of the sharks muscle. Therefore, they would not have recorded a lower temperature after falling off. The fact that it plummeted straight down to 1900 feet is a further indication that the tag fell off. If another shark had attacked this 9+ ft great white, there would have been a struggle and they would not just have plummeted down. Also, the typical attack behavior of a great white shark is to strike and let the prey die, not fight with it and take it down deep.
Having watched great white sharks at Isla Guadalupe for 13 years, I’ve seen them fight, bite each other and noticed that the smaller sharks tend to stay away from the bigger ones. Those actions always seemed to be a way to establish the pecking order and not an attempt to kill and eat the other shark. As a matter of fact, when we encountered a dead shark a number of years ago, all the other sharks stayed away from the area for a while, indicating that they weren’t comfortable being in an area with a dead one of their own.
I have no problem saying that I have no idea what happened to this shark, but for the scientists to state that a “colossal cannibalistic shark” ate this individual, simply because of the temperature recording of a tag, is not very scientific at all.
This whole thing happened 9 years ago. So why is this all over the news now? Well, according to People, The Smithsonian Channel repackaged an Australian documentary called The Search for the Ocean’s Super Predator into another doc called Hunt for the Super Predator.
So all this is done to promote a “documentary” by the Smithsonian channel. Why am I not surprised that after “Nat. Geo” and “The Discovery Channel” they are just going after sensational headlines to boost their ratings as well. Let’s just scare the heck out of people by letting them believe that there are monsters lurking in the Ocean. It’s not like people don’t have an irrational fear of sharks already. It’s not like they are killing sharks based on this irrational fear. No, they need to stoke that fear so that they can sell their stupid “documentary”. Damn the consequences!

A couple of days ago, there was a fake shark scare in Newport Beach, CA.
The Orange County Register reports:
 |
| source |
“NEWPORT BEACH – The warning was clear: A big, aggressive great white shark is on the loose along the shores in Newport Beach, and beachgoers are advised to stay away from the water.”
Problem was, local lifeguards and the U.S. Coast Guard never heard of any shark danger.
“I guess it was one of the local guys; someone who wanted to keep the crowds down at a break out there,” Coast Guard search and rescue controller Sandy Needle said about the notice. “There was nothing from the Coast Guard.”
The warning – which appeared on official-looking letterhead that said “United States Coast Guard” in the notification dated Wednesday – was floating around on Facebook, claiming that three incidents should put beachgoers on high alert.
The article goes on to give the details of the warning which contained the following paragraph:
The third sighting, the notice read, came when two lifeguards got a call about an adult-sized shark that bumped two kayakers and swam away after the boaters struck it “with an oar in the gill area of the fish.”
So far so good, it looks like the media is responsible for once and instead of hyping up a shark scare, are trying to calm the public.
The article then states, how they recognized the warning as fake.
“Although the flier looked official, there were a lot of clues that it was a fake.
“There’s a lot of misspellings, and it called a shark a fish,” Needle said.”
Well there you have it. It called the shark a fish! No self respecting Coast Guard representative would call a shark a fish! Everyone knows it’s not a fish, it’s a…. hmm, no not that, it’s a …… , I’m stumped! Any of you know?
Maybe I should be asking an expert in these matters.
