[1] Janthina globosa, commonly referred to as the violet snail, is a neustonic organism characterized by its thin, fragile purple shell and large size The maximum recorded shell length is 38.5 mm.

[2] Females normally grow to larger sizes than males, making it easy to distinguish between the sexes.

Protected by its hard outer shell, Janthina globosa has a soft body with forked cephalic tentacles on its belly, used for many different things like locomotion and receiving sensory input.

Strandings of this species and others of its genus are also due to wave and current movements (F. Betti et al 2017).

[2] Janthina globosa was first captured in 1822 off the Gulf of Antalya in the Northeastern part of the Mediterranean Sea (Teker S, Gökoğlu M , Julian D. 2017).

It is thought that Janthina globosa was used as a source of purple dye for clothes in ancient times.

This species lives its life upside down attached to air bubbles that it made itself, forming a self-made float.

This means that it does not stay as the sex that it was at birth but begins life as a male, and then exhibits a cycle of protandry, where it morphs into a female in order to reproduce.
