TIL that after an Orca killed a Great White Shark

The old shark deterrent kits the Navy used to issue to sailors was basically boiled down shark carcass! It had mixed results though.Haha no, its the last big test in Marine Corp boot camp. Basically a few days of getting hazed, eating very little and walking very far. Goot times.I think my favorite part about that is how gingerly Robin climbs down that ladder. "Okay, easy there Dick, just take it one rung at a time. Batman's not gonna bleed out right away..."I still can't get over the extremely unnecessary hang-by-legs-gymnast-move. Took him a extra 20seconds instead of just handing it down to him. I thought dick was supposed to be a world class gymnast not a 6year old in gym class

In Australia, drum-lines are used in conjunction with shark nets, and it's thought that one of the reasons they are so effective is that when a shark is caught it dies and acts as a deterrent for other sharks, at least until the line is switched out.he does carry those, but i couldn't afford both. here was the list of features though: a dry rock means fair weather. a wet rock means it's raining. a dusty rock means a dust storm. a swaying rock means it's windy. a shadow under the rock means it's sunny. a white rock means it's snowing. if the rock is jumping up and down, an earthquake is upon us. if the bottom of the rock is under water it's a flood.

Magnets are kind of hit or miss. Some sharks will pull a quick 180 when they hit 'em and some won't. Some companies like Shark Shield have had success with devices that generate an electrical field around the diver/swimmer (at the moment it's the most effective way to deter them), but these are hard to employ on a large scale. They also react negatively to bursts of bubbles, I know at one time "bubble walls" were being considered as a beach-protection measure.

Orcas are smart as fuck. There's all sorts of examples of them learning new ways of getting food. They've been observed regurgitating food on the surface so birds fly down to pick at it. Then they eat the birds.when I first saw it I was eating spaghetti and choked on some noodles and almost died. I couldn't breath for nearly a minute and my vision blacked out. The office has almost killed me, twice.somewhere there is footage from a documentary where a pod of orcas chases a blue whale mom and its calf for a whole day until the calf gets too tired to stay close enough to its mother for protection. Having separated the calf from its mother, the orcas proceed to take turns holding the calf underwater until it drowns. The orcas then don't eat any thing, and move on.
