Seals on land look really miserable!
They have tear drops trickling down their cheeks.
But the tears are not related to emotional state of the seal in any way!
As in most of the aquatic creatures, the seal produces the tears to lubricate their eyes.
They just drift off into the sea. It does not have the ducts running from its eyes
to its nose as in the case of land mammals.
So while on land the tears have nowhere to go except trickle down the face –
making it look tearful and very sad indeed!
