SCUBA divers and penguins
It just occurred to me that although SCUBA divers, like penguins, are peculiarly ungraceful and clumsy on land, wearing their tight wetsuits and carrying their heavy equipment towards the dive sites, their underwater elegance and skilful manoeuvring are nothing but admirable.
Once underwater, you cannot tell that both SCUBA divers and penguins can also do out of the water. In fact, sometimes you may catch yourself thinking that the sea is actually where they belong.
It is no wonder that SCUBA divers, just like penguins, have a burning desire to get back into the water as soon as they can.
