The Pacific Northwest was invaded by the gel-like translucent Pyrosomes.

According to foreign media reported on the 6th, the United States Pacific Northwest was recently a strange-shaped "sea ginseng" invasion, experts say this may be related to unusually warm sea water.
The gel-like, translucent organisms, called Pyrosomes, have recently gathered in areas from Northern California to southeastern Alaska near the shore and sometimes see thousands of them blocking fishnets and sometimes washed up on beaches, according to the National Oceanic and Atmospheric Administration.
experts say the number of unusual organisms appearing this year is very high and beyond normal.
the creature has caused more uproar in Monterey Bay in recent days, as fishermen have struggled to catch salmon and shrimp.
experts say scaley sea otters can be seen all over the world, often in warmer tropical waters far from the coast.
Ric Brodeur, a biologist at NOAA's Northwest Fisheries Science Center in Newport, Oregon, says some oregon slete pickers have been on the beach for decades, but he has only recently begun to report scaly sea otters washed up on the beach.
he believes that the large number of sea otters is related to unusually warm sea conditions on the shore, which are similar to the normal habitat of scale sea otters.
said it was too early to determine whether the sea otters would become permanent residents of the Pacific Northwest because the water was likely to cool.
