The boys are back at Isla Guadalupe.

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.

10 ft. white shark being eaten? Mystery solved!

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”!

Shark scare in Orange County?

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.
