New Info about sharks!

[Rivertee]

Soo this may be way old for some people but new to me. Just seen this https://www.youtube.com/watch?v=YDja7MM1gBc about a killer whale taking down a great white shark. Apparently they've figured out tonic immobility in which they turn the shark up side down and wait till is suffocates. Then they eat it! :jawdrop:


Scientist saw a drastic drop of great white sharks after the killing and concluded that the smell of death scared the others away. They were able to duplicate the scent and test it, it worked! Other sharks when the smell the death of other sharks scramble to get away as fast as possible. Shark repellant? What do you mers think?

If they could ever get that to actually work maybe but do you really need to repel sharks? They live there and generally want nothing to do with you.

I remember seeing this - thought it was incredible intelligence from the Orcas to develop that hunting technique - funny Orcas have like tribal customs almost when it comes to their hunting techniques as they vary from one pod to the next, I don't think Id like to use a shark repellant - I always want to see sharks when I go in the ocean, plus its their home, I wouldn't wanna scare them away from their hunting grounds etc

it is true that killer whales do feed on sharks. orcas are the top predator of the sea. they feed from fish to wales! they say if you get mistaken for a seal and wind up in a shark attack the best thing anyone can do is grab onto the shark's tail. the shark would think your and orca cuz thats where the target is and escape the sence.

sharks arnt really a bother but i think its a good idea because it will make the people who swear that sharks are "people eating mindless death machines" to calm the f*ck down!

im no expert on this but it reminds me of native american god spirit animal? where they believed that wolves and whales were desendants. whales would grow feet and become wolves and wolves would turn into whales. pods would tuen into packs and packs would turn into pods. this belief is popular with the Alaskan tribes and im pretty sure orcas are seen by Alaska. who knows

Orcas are really cool. Sharks are, too, but people's general lack of knowledge usually means they'll go, "oh sh*t, a shark," instead of "oh cool, a shark." Sharks can see with electromagnetic waves (according to this one scientist on a reef tour), and so they can see that your muscles and bones are much more dense than things that live in the water. Being predators that need to keep their strength and health for hunting food, they're not likely to expend energy on something that's a major risk (seriously, what kind of thing has bones in its tentacles?) and will more than likely swim away so long as you're not covered in bleeding fish (SCUBA spear fishing. Breath-hold spear fishing requires a lot of control, control that sharks don't want to mess with) or imitating a walrus that just got run over by a boat (surfing). The pod dynamics with orcas are really fascinating, and I'd love to research more about their social structures.

I agree that sharks have a horrible representation in most places. I've worked with small scale sharks and they can be just as playful and sweet as any other fish. However repellant in the case of a dire emergency I can see as a valuable tool for saving a life. I think the argument goes in many directions. Orcas on the other hand there's a lot to be known about these hunters and seemingly top predators. I'm amazed that though they have no natural enemies their numbers are still decreasing, or it could just be they're staying further out in the oceans to avoid humans. Their cultures are as diverse as ours and that include language and customs. It's fascinating that's for sure.

If you were in the open ocean and some whitetip sharks started to circle around and close in- shark repellant would start to look pretty good.

[Rivertee]

Very valid, maybe they could even use it as a rescue tool in coast guard and such for swimmers in danger.

[Arella]

Well I would also argue that it you're that worried about sharks swimming in open water where Great White's are known to hunt then swimming there is probably not your smartest move.

[Rivertee]

Sometimes sharks, even great whites, follow the bait fish inland and get closer than the norm. Most swimmers, surfers, etc know when you see bait fish to get the heck out of the water until the school passes. However there are the tourist/new commers that don't recognize the danger. Also deep sea fishermen who may fall into the ocean by accident, crash victims, lots of other accidents.

That being said yea if you're brave enough to swim in deep open water, be knowledgable of what season it is as well as your surroundings. Also great whites attack from below oddly enough there's very little warning when it hunts. Smart move on their part honestly, no alert system to scare the prey off. No fin to give away positions to other prey looking on over the horizon. Makes you wonder just how intelligent these 'fish' are.

Enough said.

I'll vouch for the FL numbers chalking it up to careless surfers or ignorant tourist. Like I said bait fish are seen get the heck out of the water!
