I found this shirt at a shop called 'Mr. Simple' in the semi-new Emporium shopping precinct in Melbourne. The store is very cool and has an enormous collection of Herschel backpacks in every imaginable colour and pattern.
This one sports blue lobsters, green eels, brown stingrays and black lion fish. Awesome.
