Titiscania is a genus of slug-like sea snails, shell-less marine gastropod mollusks in the superfamily Neritopsoidea.[2][3]
Titiscania is the type genus[2] and also the only genus in the family Titiscaniidae.
The original vernacular spelling "Die Titiscanien" by Rudolph Bergh (1890)[1] was Latinized by Johannes Thiele in 1891.[2]
Excepting some parasitic forms, Titiscania is the only genus of gastropod outside of the Heterobranchia to have secondarily lost its mineralized shell,[4] which it sheds after its larval phase.[5]
When disturbed a bluish white, thread-like substance is discharged through defensive glands in the form of about 12 densely placed white papillae on both sides of the back.[6]
