Sharks from species once thought harmless kill and eat snorkeler in feeding frenzy

Very, very slowly

The odds of you being killed by a snail are low... but never zero. And when it inevitably happens, there's no way to prove that it was intentional, that it was retribution for your crimes against this snail's entire bloodline... but I'll know.

My only regret is that I could not have killed more snails in my short life. They eat my garden.

100%

humans are the worst

Squirrels are not strictly herbivores though. It's pretty typical behavior for them to occassionally eat eggs, baby birds or other smaller critters.

Christ.

I describe the video briefly below, so don't read if you're straight-up avoiding this.

For anyone curious, it's not gory or horrendous. There is a chick, which the horse just kinda... mouths up, and the hen rushes the horse who just does care. Then more chewing.

Listen someone has to and it sounds like you just volunteered

Not being harmless os part of their charm.

If they want to hurt you... no. Maybe not with small dogs, but the same applies to small sharks.

If they're hungry and you look like food to them. Which is non-trivial.

The article is saying that these sharks aren't really sharking though. The sharks behavior has been changed by environmental factors (regular human feeding and humans raising the local sea temperature by dumping warm water from the desalination plant).

1. Sharks are attracted by usually warm water from desalination plant.
2. Tourist guide boats start chumming the waters to keep the sharks around for tourists.
3. The attraction of so many mostly harmless sharks changes their feeding dynamic. Ever tried eating an ice cream cone near a small child? Ever tried pushing an ice cream cart through a crowd of small kids? Way different dynamic as supply and demand changes as the crowd grows.
4. Formerly mostly harmless and "shy around humans" sharks start directly approaching humans as a source of food.
5. Sharks investigate human, beg for food. How do sharks investigate? By biting, nibbles really, or bumping into people swimming.
6. The first bite generates a predictably violent reaction from the humans, which triggers a feeding frenzy response. Humans aren't equipped to defend or escape this.

The point is that at every step of the way, these sharks are acting in a very strange way (for them) as a direct result of human action. We've seen this kind of thing before when people feed wild animals, strange and dangerous human seeking behaviors develop: alligators, bears, moose, etc. Dangerous animals? Yes, but the behaviors that result in human deaths are in no way natural.
