Haminoea cymbalum feeds on algae.
This shot shows the tip of my left thumb, so you can see how small this specimen is.
this species was posted on 16 June 2003 at these wesites as Haminoea cymbalum (Quoy & Gaimard, 1833) [Bulla],
I followed on 6 November 2008 Eddie Hardy and moved it to the genus Lamprohaminoea  Kuroda & Habe, 1952,
I found by chance W. B, Rudman (1971)."On the Opisthobranch Genus Haminoea Turton & Kingston". Pac Sci 25(4): 545-559, Rudman clarifies, that the genus Lamprohaminoea is invalid.
So I moved it on 25 August 2011 back to the genus Haminoea  Turton & Kingston in Carrington, 1830 on 25 August 2011.
All of these species have orange spots of various sizes and are very similar:
Haminoea sp. 01 which differs by its greenish-yellow, black and purple spots, none of them is surrounded by opaque white
Haminoea sp. 02 which lacks broad orange bands and spots surrounded by opaque white
Haminoea sp. 04 which has a white appearance and large orange spots.
Haminoea ovalis which differs by black spots and/or markings.
