I agree with Tamar, most probably a whelk egg case! There is definitely algae growing /on/ it, though. It'll be difficult to get the right species from this, but maybe start with Busycon genus?
Hi Juan! This reminds me a lot of Whelk egg cases:

I just don't know what species. It is not the same as the ones referenced above but seems quite similar in structure to me.
