This is one of those rare (and extremely weird) seeds which sometimes gets submitted to the website. Not far from spawn you will be able to find two floating monster spawners in a mesa biome. They are literally floating in air above the ground. I have never seen anything like it before. It’s a pretty cool seed!

How to find the spawners?
The spawn is on a medium sized survival island. But that’s probably not the reason why you decided to check out this seed. To find the floating monster spawners walk diagonally to your right and then swim across the sea until you get to a mesa biome.
Just continue ahead until you reach the shore of the mesa biome.
Walk up on land and then walk to the other side of the small peninsula and there you will find the spider monster spawners.
The spawners will only spawn spiders during night. If you’ve got cheats enabled type the following text command: /time set 15000
It’s a very weird seed. I have tested plenty of the different seeds during the last couple of years and this is the first time I ever see this!
