Looks like root Ginger! XD

Its a weird shape but is it not just a nodule of some kind?

Dunno maybe it is ginger, it doesn't smell of anything it has come from the beach.

Where did you find these pleas -  I'm assuming these are small sponges found in gravel or beach

They could be casts of the crypt of a boring bivalve, from which the enclosing rock has disintegrated. 
As trace fossils, they are also given names - look for Gastrochoenolites.
These are common features of a hard surface (eg limestone or phosphate) that has been exposed on the sea floor for a long time.  The bivalve(s) that bore them will have done so using either mechanical abrasion or acid-etching.  Once enclosed in the crypt, they outgrow the aperture and are permanently trapped in rock.  But it is a safe place to grow!  Look up Lithophaga (Date Mussel) for modern examples.  I actually picked up some Gastrochoenolites this morning, bored into derived Jurassic phosphate nodules at the base of the Cretaceous in a North Lincolnshire locality.  The Piddock shell does something similar on British coasts.
