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.
people would wear feather hats and eat more tomatoes
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!
The pressure and weight under your foot exceeds the resistance of the scorpions exoskeleton therefore you crush fairly
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
they would be fat
If they went extinct the whole food chain would be out of balance.
they will be extinct
They become extinct.
It would effect the food chain and other marine life would become extinct
bullfighters would be out of a job
It would be sad.
