Found on a beach in Dubai - but what are they?

These are like small stones, approx 2-3cm long, rounded and bulbous at the base and tapering to a small vent hole at the top. Appear to have only this one entry/exit/breathing hole...  Found them washed up amongst shells on a sandy beach at the low tide mark.  No signs of any animal inside them... but are they shells, or larvae of some sort - or maybe a by-product of the construction taking place offshore?
