The first year we went to Goa we were swimming in the sea and my partner felt something on his arm , he lifted it and saw that a snake had wrapped itself around it - needless to say he screamed and chucked it as far as he could. He was lucky not to have been bitten 'cos they're poisonous!
We have seen quite a few sea snakes since that first visit, a least once a
year, although they are usually washed ashore and dead.
There was a massive spider in our room last week (I didn't look at it but it made Jon jump, and he's not usually bothered by them).
And that cyclone that hit Goa on Wednesday night was pretty scary. The lightning we could deal with but when sunbeds started flying through the air and palm trees were snapping on the ground it was time to run!!!!
