It is that time of the year again: gales, rain and darkness. The only good thing about late autumn/winter to me is that the wind blows interesting things on the beach. Portuguese Men o’ War (Physalia physalis) have been a common sight the last few years (see this post from 2017), perhaps more so than it used to be, but not sure this has been properly investigated. Yesterday we saw several dozen at Loe Bar near Helston, including the smallest specimen I have seen so far. No By-the-Wind-Sailors Vellella and no Violet Snails Janthina, and definitely no Porpita or Glaucus; maybe someday!

Very cool! It would be extremely noteworthy for a Physalia to wash up on my beaches, but we do get lots of Velella sometimes.
Hi Allison, I have not seen Velella yet this year; I would have thought that if the currents washed one species up the shore, it would also wash up the other. I guess we know little of what they are up to in the middle of the ocean!
