When traveling with the help of public transport, one should expect to see some interesting things. Public transport, as it is stated, is open to the public for all to use. It's a great option for many people for many different reasons, so seeing a wide variety of people is not uncommon.

Among this variety, though, you may see some wildly unusual things, things you may have never seen before. People with strange cargo, people with live cargo and people who you really would like to know where they are going and what they are doing.

Traveling by use of public transport is not only a cheap and relatively accessible way to travel, but it also provides entertainment, too. On Reddit's "Subway Creatures," users of the subway, bus or other modes of transport, document their most unique and interesting sights spotted while on board.

Here are 15 certified subway creatures spotted in real time on their travels.
