Two images of same specimen in air (left) and in water (centre). M. denticulata, as above, that are occasionally found on saltings in muddy conditions with M. myosotis, have bodies as dark as that species.
Paler juvenile from same habitat on right.
The tentacles on all forms are usually grey or greyish. The sides of the foot are paler than the dorsum of grey specimens.
The mantle sometimes projects (1) a short way beyond the aperture rim of the palatal lip, but is not reflected onto it.
The head has two cephalic tentacles; nearly linear with a bluntly pointed tip (subulate) when dry(2), and conical and paler when swollen with water (3).
Shell height 6.1 mm. Salting on tidal River Dee, Flintshire, Wales. December 2018.
13 Myosotella myosotis form denticulata.
