When extended, this slug can attain a length of 12 cm (5 in.). It is highly variable in coloration and positive identification depends on
dissection and inspection of the
genitalia. It is usually very pale in color, ranging from mottle pale yellow, cream to white. It may have irregular black spotting or speckling all over the dorsal surface that may coalesce into two poorly defined bands running down either side of the body; in the juveniles, these two bands may be clearer and better defined as grey bands, especially anteriorly. Occasionally the slug can be mostly brownish. The only constant color character among different
Caribbean island populations is the eye stalk, which is bluish grey with a light brown tip. == Distribution ==
