Swimming snails and their gelatinous, winged feet!
These are all snails who’ve given up on life slipping and sliding along the sea floor and have grown fins so they can swim through the ocean.
There are Sea Butterflies who keep their shell and come in all sorts of shapes and sizes;
Sea Angels who lose their shell at an early age and look more like slugs;
Atlantids who are microscopic and have a large, coiled shell;
And Sea Elephants, some of whom have a teeny shell that looks more like a hat and others who lose their shell completely.
I’m so glad to see that snails have such options!
