**Cancer harenam bullans** (Anglice: *sand-bubbler crab* et *sand-bubbler*) est quodlibet nonnullorum brachyurorum generum ***Scopimera*** et ***Dotilla*** familiae Dotillidarum. Ea sunt parvi cancri quae in litoribus harenosis trans Indo-Pacificum tropicum et subtropicum habitant; aestu recesso, conspicuas globulorum harenae congeries deponunt, quos aestus accedens destruit.

Descriptio
----------

Cancri harenam bullantes sunt parvi cancri, circa 1 cm trans carapatium,? et eorum est habere "fenestras gasosas" in mero crurum; inter *Dotillas,* hae fenestrae in thoracis sternitis? quoque adsunt. Systema simile se in genere *Petrolisthe* familiae Porcellanidarum in parallelo evolvit?.

Distributio geographica
-----------------------

*Scopimera globosa* et globuli harenosi quos fecit.
Cancri harenam bullantes sunt longe lateque trans regionem Indo-Pacifici diffusi, ubi abundanter in litoribus harenosis in tropicis et subtropicis vivunt.

Oecologia et mores
------------------

Cancri harenam bullantes in cuniculis sub harena aestu accesso manent; aestu recedente, in superficiem emergunt et grana harenae pro cibo detergent, ex quibus globulos inflatos formant, quae superficiem mox contegunt. Cancri radiis ex aditu cuniculi moventur, in quem iterum ingrediuntur dum aestus accedens globulos destruit. Materia quam cancri harenam bullantes consumunt habet minimam materiae organicae conglobationem, quae in unum confertur per egestationem materiae quae non est facilis ad concoquendum.

Taxinomia

### Historia taxinomica

Primus descriptus cancer harenam bullans fuit *Cancer sulcatus* (nunc *Dotilla sulcata*), a Petro Forsskål anno 1775 erectus. Genus *Scopimera* primum descriptum est subgenus *Ocypodis*? a Gulielmo de Haan anno 1833, sed prima species, *Scopimera globosa,* firme descripta est anno 1835. Eodem tempore, de Haan erigere genus *Dotonem* pro *Cancro sulcato* Forskålensi conabatur, de genere *Dotone* molluscarum insciens, quod nomen praeoccupabat. Primum illius generis nomen iucundum a Gulielmo Stimpson anno 1858 divulgatum est, qui id *Dotillam* appellavit. Veri simile est persistentis emendationes taxinomicas genus *Scopimeram* in saltem duo genera diffissuras esse.
