It has a different coloration than the one pictured here. It has orange, black and blue stripes with a white patch on the mid back. Is this C. hirundinina?

In general the photo has the same T-shaped mark on the headshield as Indo-West Pacific specimens of the species but Humann's photo shows an orange rather than black background and lacks the yellow lines of Indo-West Pacific animals. The Caribbean fauna has lots of interesting links to the Indo-West Pacific such as Micromelo undata and Hydatina physis so there is insurmountable problem with Chelidonura hirundinina having a circumtropical distribution. Like many of these animals there is little published information on their anatomy and colour variability. Until we know more about the Caribbean animal I would prefer to remain undecided. I you have photos of the Caribbean animal they would be a welcome addition to the Forum.
I note that Humann gives Chelidonura hirundinina the common name Leech Headshield Slug which I guess was an attempt to appease the publisher's misguided belief that we can't survive without common names, even if they are manufactured artificially for the occasion. I presume Headshield Slugs comes from the Order Cephalaspidea, but Leech is clearly an error based on Hirudo = leech rather than the Hirundo = swallow. The scientific name of Chelidonura hirundinina certainly over-emphasises the shape of the 'tail' in these animals. Chelidonura is made up of chela (as in a crab's claw) and nura = tail. Also hirundinina = little swallow, which is another reference to the tail, so reminiscent of the bird's.
