Here are some of the weirdest creatures that have washed ashore in the last decade. .

But in October 2013, a monstrous giant squid washed up on a Spanish beach.

The tentacled behemoth measured 30 feet (9 meters) long and weighed 400 pounds (180 kilograms) — that's about the same weight as an adult brown bear. .

In 2020, an even larger giant squid turned up in Britannia Bay, South Africa.

The specimen was remarkably intact, and was likely more than 13 feet (4 m) long and weighed over 660 pounds (330 kg), Live Science previously reported. .

Scientists later explained that the blobby body was probably the remains of a whale, and that the hair-like strands covering it were most likely decomposing muscle fibers. .

It was a rare find as well as a startling one, since these fish usually lurk in dark water around 3,000 feet (914 m) below the surface and are kind of spooky-looking.

Park officials determined that the body was most likely that of a Pacific footballfish (Himantolophus sagamius); a rather light-hearted name for such a frightening fish.

Visitors to Penzance beach found it covered with tennis ball-size creatures fondly known as "heart urchins" or "sea potatoes."?

A beach on Catalina Island, California was host to a rare sight in June, 2015: a huge deep-sea oarfish.

As the name suggests, these fish usually keep out of sight in deep water.

There was no doubting the oarfish's sex once they'd discovered a pair of ovaries that were 7 feet (2.1 m) long and weighed 24 pounds (11 kg).

In 2019, a California beach became the scene of a mass penis fish beaching.

The glassy creatures turned out to be by-the-wind sailors, hydrozoans related to the Portuguese man-o-war

Winds likely blew the creatures right up onto the sand, where they left both a strange sight and a strong smell. 

They got an extra fright when the fish turned out to be alive

The large fangs are used for chomping crustaceans, squid and fish, including other lancetfish. 

The stranded fish was released in deeper water but later turned up on the shore again, suggesting it was too sick to make it back out to sea.
