A cluster of giant green anemones at low tide with sand and rocks visible just under the water, and a large rock protruding from the water on the right hand side of the image. Two of the anemones are light in color, but one is larger than the others and is more green than the others.

Two very different types of #jellyfish. First, an extremely limey neon green specimen - unsure, but likely #Cunina sp., and then a wacky #Zancleopsis grandis, recognizable by its “two long, two short” layout of its tentacles.

A #Siphonophore, which are often mistaken for #jellyfish, are quite common in the midwater environment. This species has a bubble of CO connected to its “top” to self-right. PSA - it’s on the “do not lick” list.
