Weekend #Plankton #Factoid 🦐🦠
Slug news! Blue Sea Dragons (Glaucus atlanticus) are #Nudibranchs, a soft gastropod "sea slug", which as neuston #zooplankton, float at the water surface. Their extended cerata fingers are used to swim and capture prey.
Beautiful, but don't touch these dragons because they eat floating siphonophores like Portuguese man o' war and concentrate their stinging #nematocysts into sacs, which they deploy if disturbed into a *very nasty sting!
