11 strange things that washed ashore in 2021

Beaches across the globe saw their share of weird blobs wash ashore. Sometimes this shoreline debris was small and weird, like a tangled rope coral that found its way onto a beach in Texas, or the tar balls that dotted Israel’s Mediterranean coastline in February. Other times, the organisms numbered in the millions, such as the by-the-wind sailor jellyfish whose corpses stranded across shores; and in other instances, the beached animal itself was a behemoth, such as the rotting body of a nearly 10-foot-long (3 meters) “river monster” spotted near the Gulf of Mexico this year. Here’s a look at the wild and strange “things” that washed ashore in 2021. 

Millions of ‘sailor’ jellyfish

Every year, millions of by-the-wind sailor jellyfish (Velella velella) wash up and die on beaches around the world. These jellies float near the top of the ocean, and have a little sail on their backs that catches wind and pushes them from one feeding ground to the next. When wind patterns change with the seasons, huge colonies of the jellies can end up stranded on the shore. Sometimes, those colonies include thousands of individual jellies; other times, they include millions.
