The world's largest breed of jellyfish has washed up on the banks of Maine before, but this year were larger Lion's Mane jellies than is typical.

The stinging jellyfish can grow to immense sizes, with tentacles over 100 feet long. Luckily, the ones who wash up in Maine rarely reach those lengths, but coastal regions have recorded a rise in larger-than-average jellyfish this year, according to NECN.

The total number has not gone up, just the average size of the jellies showing up on shore.

Nick Record, a senior research scientist at Bigelow Laboratory for Ocean Sciences, says in the article that jellyfish reports range from about 300 to 700 per summer and this year's total number of jellyfish is on track to be about the same.
