Spotting

Description:

This is another specie which I cannot identify. It looks like a leech but doesn't totally look like it, I think? It is green and slimy and people in our place stay away from it when seeing it because we get scared thinking it could be harmful. Our beach where I saw this is fronting the Pacific Ocean.

Habitat:

Sand; coral reef

Notes:

Our beach where I saw this is fronting the Pacific Ocean. The other pics shows the beach when it is low tide. No sand at all! Only coral reef where people can walk
