If the arthropods went extinct, it would SERIOUSLY threaten human civilization. For one thing, bees are arthropods and they pollinate most of our food crops. Ants aerate the soil. Spiders keep a lot of insects in check. Without spiders we'd be knee deep in bugs everywhere! Crustaceans are good to eat.
Sorry, but while sea scorpions used to exist, they are now extinct. They lived about 390 million years ago.
I do not think they are extinct, they may have altered their habitat to brackish (semi-salt water) and gone inland, perhaps in the Amazon. these creatures are NOT recommended as pets!
Arthrophobia would be fairly accurate.
Scorpions make good lizard food. There are many predators to scorpions, birds, cats, mice, rats, even humans in certain locations eat scorpions. So lizards eat scorpions, spiders eat scorpions, scorpions eat scorpions and people eat scorpions. I'm sure pocket mice eat scorpions!
Scorpions stowed away on ships that were going to Hawaii from places that had scorpions in them already. They are stoic and adaptable creatures and can survive almost anywhere.
Nope.
no not at all
It would be extinct. As in no longer in existence. It would not be here anymore.
other animals that relied on it would die and come extinct
we would all be in caves or extinct
If they went extinct the whole food chain would be out of balance.
They become extinct.
they will be extinct
It would effect the food chain and other marine life would become extinct
bullfighters would be out of a job
then you would not even be here
Then there would be no human nature.
