Kurtiella is agenus of mussels from the lentil mussel family(Montacutidae). The species of the genus are known as commensals of echinoderms (echinoderms). The generic name honors the mussel specialist Dr. Kurt Ockelmann.
features
The housings with the same flaps are small (less than 9 mm), usually longer than high and moderately inflated (thick). They are unequal, the vertebrae are slightly behind the middle of the length of the case.
The Prodissoconch (embryonic and larval housing) is lens-shaped, slightly inflated and has a Prodissoconch II, which can also be missing. The dissoconch (juvenile and adult housing) shows a fine line sculpture parallel to the edge and, more rarely, a radial microsculture consisting of very fine, diverging lines. The ventral edge of the housing is smooth, the edges of the valve are close together (they do not gap). The lock plate takes up about half the length of the housing; extends at the dorsal margin on both sides of the vertebrae. Below the vertebrae, the lock plate is interrupted by the notch in the large, internal ligament. The lower part of the ligament is calcified and forms a lithodesm. The right valve has two short but clearly pronounced lateral teeth that delimit the ligament at the anterior and posterior dorsal margin. They are separated from the dorsal margin by distinct longitudinal pits. The left valve has only two indistinct lateral teeth, one front and one rear, which are practically only swellings on the lock plate. The anterior and posterior sphincters are almost the same size. The pallial line is clear and not indented. The shell of the Dissoconch is whitish, the Prodissoconch whitish to brownish. The gills consist only of the descending part of the outer gill leaf (half gill). Labial palps can be present or absent. The foot is hatchet-shaped with a ventral keel.

Geographical distribution, habitat and way of life
