Mmm - beautiful photo, Hive account@rafaeleff15 :-) I see a small river on a beach, where the tide has run out, and a stone or even a large animal tooth (we used to often find cow teeth on the beach where I grew up on the west coast of Scotland - they are very durable and there is farming land all around the coast)....either way, it looks like something heavy which has caused ripples and pathways of a stream of water to flow around it.
I love imagery like this, where water plays and creates with the sand, and leaves ephemeral 'drawings' of where it has flowed... it is relaxing to look at. Thanks for asking, for the prompt to respond :-) Blessings!
