Strange 'sea pickles' keep washing ashore along the Pacific Coast

There are strange sea creatures known as sea pickles invading the Pacific Northwest. These gelatinous and somewhat translucent organisms, called pyrosomes, have been seen congregating, sometimes by the thousands, close to shore from Northern California up to southeast Alaska clogging fishing nets and washing up on beaches, according to the National Oceanic and Atmospheric Administration. Experts say that this year, the critters are appearing in very high numbers outside the normal range of the species.
