180 degree rotating Nudibranch experience

Nudibranchs are mollusks in the class Gastropods, which includes snails, slugs, snails, and sea urchins. Many gastropods have shells. Nudibranchs have a shell in the larval stage, but disappear in the adult form. Gastropods also have legs and all young gastropods undergo a process called torsion in their larval stage. In this process, their entire upper body rotates 180 degrees at their feet
