We should teach crabs to read so they can learn how to speak. Maybe one day the crabs will be able to speak their thoughts and tell us how to help the human race. Also, if you don't like someone then you could have a crab go into their house and take notes and spy on them. 

Snakes are one of the many enemies to crabs. It is just the natural cycle. Teaching crabs to read can really improve the crab's well being as well as humans. But if we taught crabs to read then they could tell the snakes to stop being rude and then they wouldn't have an enemy to that species anymore.

If we taught crabs to read that could prove that other sea creatures could learn how to read. Although crabs would be the most beneficial because they are sea and land creatures and they have dope pinchers.

Mostly though, crabs are already kinda smart so why not make them smarter? If we taught crabs to read we could have them sit in classrooms and explain books to children. They could also help scientists learn more about their species and other species they interact with. Like dolphins and sharks.

All in all, we should teach crabs to read because it would not only be beneficial to the species of crabs and humans, it would be pretty sick to have a crab that can read.
