To a small fish, that clump of seaweed might look like a tasty meal. But is that seaweed clump actually a predator in disguise?
Does this picture look innocent to you? Look harder.
Lurking somewhere inside the seaweed is our next weird lookalike...if you can spot it.
Need a hint?
It's right here. This is the sargassum fish.
This four-inch hunter has evolved to mimic the sargassum algae that surrounds it.
Its skin has the texture of seaweed.
The white spots resemble tiny worms that are prey for the small fish, who have no clue they're being watched...sized up...and swallowed.
Look closely at the sargassum and you can see its meal struggling inside.
But only for a moment.
