Titiscania limacina Bergh, 1890 |
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]
Species within the genus Titiscania include:
