Answer: Jellyfish tentacle

What you're looking at

A jellyfish tentacle is one of the long, trailing appendages that hang below a jellyfish's bell-shaped body. You'd normally see these underwater, either drifting gently in the ocean or sometimes washed up on beaches. They're the jellyfish's primary tool for catching small fish and plankton.

When photographed under extreme magnification, a jellyfish tentacle reveals an intricate texture of tiny pores and cellular structures that look almost alien. The close-up shows the bumpy, organic surface where the stinging cells live, making it nearly impossible to identify without seeing the wider context. This is why 3 people took their guesses before the answer was revealed.

Look for repetitive, bumpy organic textures with tiny pores scattered across a translucent or semi-transparent surface.
