Chelidonura amoena Bergh, 1905
Lovely headshield slug
Maximum length: 55 mm
The pattern of this species is variable, but the body is often
in white to light yellow translucent tones,
of which a certain density of black spots predominates on the upper parts.
The elongated body consists of a head, which is called ‘head shield’ due to its shape.
There are no rhinophores, but a pair of chemical receptors located on each side of the head,
slightly behind the shield.
