The items you may stumble upon at the beach are usually nothing out of the ordinary. Apart from seashells, dead corals, and algae that washed ashore, you may also find rocks, pebbles, and, unfortunately, litter.
However, some people come across interesting finds that you won’t see during a typical day by the ocean. We’re talking about oddly colored sea creatures, jewelry from eons ago, and eroded parts from what appears to be an ancient sea vessel, among many others.

#3 These Things Washed Up On A Beach In East Australia, Anyone Know What It Is?
Redditor froguille replied:
"Blue glaucus (glaucus Atlanticus) I believe they're also called blue angels. Only reason I know is I used to research sea slugs and sea cucumbers during my high school study halls....."

Since the planet is made up of 70% water, it’s inevitable for things to end up in the ocean. A 2020 study painted a picture, revealing an estimated 23 metric tons of plastic waste in waterways in 2016.
These figures likely do not include the 28,000 rubber duckies that fell into the Pacific Ocean in 1992. The kiddie toys came from a freighter that capsized while traveling from China to America after being caught in a storm.

A similar incident occurred in 1997, when a cargo ship carrying five million LEGO bricks capsized off the southwest coast of England. The sea vessel was traveling from Rotterdam to New York and lost all 62 shipping containers.
The incident, more infamously known as the Great LEGO Spill, is deemed the “single largest toy-related environmental disaster in history. Many experts claim that people continue to find LEGO pieces to this day.

Finding plastic toys in the ocean is one thing, but what if you stumble upon something so strange-looking that it causes panic in you? This is what happened in 2019, when a mysterious-looking orb washed up on the shores of East London.
Police initially suspected it to be an unexploded bomb and called on inspectors to investigate. But upon closer look, it turned out to be a giant Christmas bauble.

Due to the large number of discarded items that fall into the ocean, many experts have used them to track currents. In 2023, Kagoshima University Professor Shigeru Fujieda stipulated that disposable cigarette lighters could be an excellent tracking tool.
“Disposable lighters are one of the few types of marine litter that have evidence of their source, because they have printed information about the consuming country or city (e.g., point of sale address or telephone number),” Fujieda wrote in his paper published in the Regional Studies in Marine Science.

According to research ecologist Andrew DeVogelaere, discarded items that wash up ashore can be removed. The problem arises when items like hazardous medical waste, for example, sink to the bottom of the ocean and become trapped there.
“We don’t even know the names of a lot of these things,” he told Popular Science. “We’re impacting a whole ecosystem that we don’t even understand.”

#18 Sealed Glass Vial On The Beach
We found this small sealed glass vial with an orange liquid inside that had washed up on the beach in Scotland. Any ideas what it could be? Should I resist the urge to crack it open.
occasionalrant414:
It's in too good a condition to be, but it sort of looks like the acid ampoules the British used on limpet mines and other demolition munitions during WW2.
They worked by being put into the detonation system, then being crushed. The acid would eat through copper wire (different thickness of wire slowed down or sped up the time). Once the wire split, the detonator would trigger and bang.
The ones I saw, admittedly years and years ago, were a bit flatter? I saw them in a museum in Portsmouth back when I was at college - 20+yrs ago. They came in a impact resistant case.
Can't be, but looks similar.

#83 Dense Rubber-Like Slab Washed Up On The Beach
What is this thing? Northern California beach. It was very dense and heavy, maybe 40-50 lbs. Definitely not foam. Smooth-ish and kind of waxy/hard on the outside. In picking a corner off, it seemed a little softer inside, possibly rubber, but all the other rubber finds seem to be layers of dark material, and there were no layers to this. No smell. We didn't have any tools to cut into it. Thanks for your ideas!
Latter-Scallion-4755:
I used to work for Goodyear and actually done the job that used these. It's definitely a slab of pure rubber from rubber trees in Africa. Other ingredients went in to color it black and others to make it more plyable and easier to work with. And yes people rubber actually comes from trees believe it or not...
