The main reason why I was scared playing on the beaches of Udupi. Would you have been scared too?

I have been to the coastal city named Udupi in November 2021 which is like 400 km from our city Bangalore. Even though Udupi is an amazing coastal city, I was scared on the beaches. I had enjoyed a lot on the beaches of Goa back in 2016 and also on Kovalam beach in Kerala back in 2017 but the I was often keeping on the beaches of Udupi. Thats because there were crabs on the beaches of Udupi. There were some hidden in the sand which were coming out. The crabs weren't that big but still I wouldn't wanna get stung by one. While playing in the sea water too I was scared that what if a crab stung my feet or something. I didn't have to worry about these in Goa and Kovalam beach.
