Beachcombers have been finding much more than shells on beaches this year. In fact, the beach has seemed more like a grocery store or museum, with everything from cans of coffee to rocket parts washing ashore. We've compiled a list of the strangest things found on beaches so far in 2015.

1. Coffee Cans, Ramen Noodles and More

In December, residents of Florida's coast walked outside to find dotted throughout the sand. The beach was turned into a veritable grocery store of items when containers fell off a cargo barge in the waters from Cape Canaveral to Palm Beach.

2. A Bomb

In August, a family on a beach outing in Wales were shocked to find out the 'buoy' the kids were playing with. The kids were jumping and playing on an unexploded World War II-era mine bomb.

The Royal Navy coast guard detonated the bomb in a controlled explosion shortly thereafter.

3. Rocket Wreckage

In May, Kevin Eichelberger was on a Bahamas getaway when he discovered on the beach. The Falcon 9 rocket had successfully delivered supplies to the International Space Station and a failed landing caused it to explode and crash into the ocean. The debris had GoPro cameras on it but Eichelberger didn't find any data.

4. A Prehistoric Megalodon Tooth

In October, a beachgoer in North Carolina found a . Six inches long and about the size of a hand, this tooth came from a creature that once lived to be about 60 feet long. Rain and high tides from Hurricane Joaquin brought the fossils ashore.

5. Giant Purple Sea Slugs

In June, washed ashore in California. The strange creatures are actually known as sea hares. El Niño's warmer water encouraged them to make a beeline to the shore.

6. A Really Expensive Yacht

In March, lifeguards at the North Island Naval Beach in Coronado, California found after a flash storm. The $200,000 luxury boat was sunk after sand began to fill up the staterooms.

7. Hypodermic Needles

In September, a Los Angeles beach was closed down after and water samples came back showing high bacteria levels. Hypodermic needles, tampon applicators and condoms were all found on the beach after heavy rains caused a malfunction in one of the pumps of nearby Hyperion Treatment Plant.

8. Creepy Oarfish

In August, a washed up on the beaches of Santa Catalina Island off the coast of California, a startling sight for beachgoers. The dead fish was 15 1/2 feet long and officials estimate it probably weighed as much as 200 pounds. It did not have its tail - sometimes oarfish shed their tails to save energy - but would have been around 24 feet long with it. Scientists hypothesized that earthquakes could be the reason why the oarfish washed up on the beach, while others posited it may have been because of El Niño's warm water currents.

9. Tar Balls

In May, at Manhattan Beach in California. The dangerous tar balls caused the beach to close for cleanup. Officials were unsure of whether the tar balls came from an oil spill or a local refinery.

10. Human-Sized Chunks of Ice

In March, began appearing on the coast of Cape Cod National Seashore in Massachusetts. The mounds of ice looked like icebergs and some were bigger than humans. CBS Boston's chief meteorologist Eric Fisher called it a "once-in-a-generation" event.

11. Rare Sea Serpent

In December, a washed onto Huntington Beach in southern California. The yellow-bellied sea snake was dead when a coastal cleanup crew discovered it, but alive its venom has the power to paralyze. It's believed that El Niño's temperature changes could have lured the snake north to hunt fish and eels.
