“…The first two genera include either boring or crevice-enlarging endolithic species, whereas representatives of the latter three are endobenthic, endolithic and epibenthic inhabitants of soft substrata, respectively. Recent species of Dacosta, Dianadema and Bryopa are comparatively well known (Owen 1835;Soliman 1971;Appukuttan 1974;Savazzi 1982aSavazzi , 2000Morton 1984aMorton , 2003Morton , 2005, whereas Stirpulina ramosa Dunker, 1882 is the only known extant species of tubedwelling Clavagellidae and is restricted to Japan (Habe 1952). Kuroda & Habe (in Kuroda et al 1971: 481) proposed the genus Stirpuliniola for this species (Habe 1977: 315, pl.…”

Extant species of Clavagella sensu stricto, including representatives of its subgenera, are comparatively well known (Owen 1835, Soliman 1971, Appukuttan 1974, Morton 1984a, Savazzi 1982a, 2000 whereas Stirpulina ramosa Dunker, 1882 is the only known extant species of tubedwelling Clavagellidae and is restricted to Japan (Habe 1952); little is known of either its anatomy or its biology. Nowhere common, it is thought that the Clavagellidae arose in the Late Cretaceous of the Tethys and radiated thereafter to become nearcosmopolitan, with early representatives of Clavagella described from North America, including the Turonian of California (Stallwood 1995), Europe, Africa and India ( Forbes 1846, Stoliczka 1870, L.A.

In the Indo-Pacific, it is recorded from the Recent of several localities, principally the Red Sea (Soliman, 1971), southern India (Appukuttan, 1974), the Philippines (Savazzi,2(00) and Japan (Morton,2(05).

Hitherto, the bivalve watering pot shells (Subclass Anomalodesmata) have been considered to be all contained within one superfamily the Clavagelloidea -it too possessing but one family and generally comprising two functional clades: (i) the extinct Clavagella and the nestling/boring Dacosta and (ii) the endobenthic Brechites, Penicillus, Foegia, Kendrickiana and l\JipponocIava (plus the fossil Pseudobrechites and I!\!arnea), and Stirpulina. The cemented Pliocene-Recent Humphreyia can be derived from an endobenthic Brechites-like ancestor (l\JipponocJava), making a third functional entitv. The genus Dianadema also comprises species that are cemented. l{ecently, the endolithic Blyopa has been proposed as a fourth clade and a unique extension of the clavagellid line of evolution in which the anterior region of the right valve is dissolved as the animal bores deeper. The above studies, in broadening our understanding of the range of superfamilial functional diversity, however, raise questions with regard to the, as currently defined, taxonomic arrangement of the Clavagelloidea.Species of the extinct genus Clavagella and their extant allies, notably Damsta, have an internal ligament (but no lithodesma) located between chondrophores, both adductor muscles, a pallial line with a pallial sinus, and no pedal disc. Further, although Dacosta, Bryopa, Dianadema and Stirpuiina cement their left valves to the wall of their crypt or adventitious tube, the right is free inside it. Conversely, both shell valves of Brechiles and its allies, including the cemented Humphreyia, become surrounded by and united marginally with an adventitious tube and to which they are then fused by a calcareous secretion produced from the underlying mantle. Moreover, Brechiles and Humphreyia have an external ligament (the latter with a lithodesma), are functionally amyarian as adults, have no pallial sinus and develop a watering pot anteriorly, internal to which is a highly muscular pedal disc. Most important, however, flumphreyia, at least, has a distinct post-planktonic life history stage in which a free-living, typical bivalve juvenile, metamorphoses into a tube-dwelling adult. At this time, shell growth ceases and only the tube can be extended posteriorly and repaired. This is not the case with Clavagella and its allies although at some stage the juvenile does cement itself to its burrow wall but shell growth, especially of the free right valve, can continue.All watering pot bivalves possess juvenile shells that in overall form and in the possession of distinct radial striae are reminiscent of representatives of the Lyonsiidae, suggesting a possible ancestry. The clavagellid fossil record shows that Clavagella and its allies (Dacosla, Bryopa, Dianadema and Stirpulina) : 10.18195/issn.0312-3162.24(1).2007.019-064 20 between the endobenthic tube-dwelling Stirpulina (Clavagellidae) and Brechites (Penicillidae) and the cemented Dianadema (Clavagellidae) and Humphreyia (Penicillidae). Only Dacosta and Bryopa (Clavagellidae), however, ...
