It’s a whelk, but it’s massive. That’s an iPhone 11, 15mm+ without the case. What type of whelk though ?  Is it a record ? West Sands, St Andrews, found whilst training to beat the four minute mile (nae chance). 

You're right: there's no way a whelk could break the 4-minute mile barrier.

Sorry, not really an Apple devotee.  Which one is  the whelk?

You might have heard this before....I've seen bigger.

Red Whelk I think. It would normally have fine spiral grooves but has probably been tumbled along the seabed by the waves for some time so is smoother than typical. A good size individual though it occasionally grows up to 20cm. The largest I've found on my local beach is a mere12cm.

(Apologies for interrupting the excellent witty replies!)

When did Apple shrink the iPhone 11? 

This post is a welcome distraction....

Whelk-come..... I get it!
