  1. Arrivée de la fiche d'un petit #bivalve des côtes européennes : la #spisule tronquée.
    Il s’agit de l’espèce la plus commune sur les plages de la mer du Nord.

    MÜLLER Yves, LE GRANCHÉ Philippe in #DORIS, 05/05/2025 :
    Spisula subtruncata (da Costa, 1778), doris.ffessm.fr/ref/specie/594

  2. Nouvelle fiche de petit #bivalve européen (pas un bénitier, cette fois !) publiée sur le site : la syndesmye ovale.

    MÜLLER Yves, LE GRANCHÉ Philippe in : #DORIS, 26/03/2025 :
    Abra segmentum (Récluz, 1843), doris.ffessm.fr/ref/specie/579

  3. Une troisième fiche descriptive de #bénitier (d'autres arrivent encore 🙂 ) avec une toute petite distribution #Pacifique (vers la #Nlle-Calédonie pour nous) :
    le bénitier du diable.

    MÜLLER Yves, FAUVELOT Cécile, PENIN Lucie in : #DORIS 25/03/2025 : Tridacna mbalavuana Ladd, 1934, doris.ffessm.fr/ref/specie/586

  4. Une fiche de #bénitier #tropical en plus (d'autres arrivent), avec une large distribution #IndoPacifique : voici la grande tridacne gaufrée.

    MÜLLER Yves, FAUVELOT Cécile, PENIN Lucie in : #DORIS, 22/03/2025 :
    Tridacna squamosa Lamarck, 1819, doris.ffessm.fr/ref/specie/324

  5. #Genomes of enigmatic tusk shells provide new insights into early molluscan #evolution phys.org/news/2023-09-genomes-

    #Scaphopoda is the sister taxon to #Bivalvia: Evidence of ancient incomplete lineage sorting pnas.org/doi/10.1073/pnas.2302

    "#Scaphopods exhibit a mosaic of features resembling other lineages: tentacles like the arms of #cephalopods, unique shell ontology similar to #bivalves, and a partially degenerated head that seemingly represents an intermediate state between bivalves and #gastropods"

  6. A #clam presumed #extinct for 40,000 years has been found alive sciencenews.org/article/clam-p

    A #fossil species found living off southern #California, with notes on the genus Cymatioa (#Mollusca#Bivalvia, Galeommatoidea) zookeys.pensoft.net/article/95

    The researchers still puzzle over how the critters eluded #science for so long. One idea is that C. cooki’s preferred habitat is farther south, perhaps in a remote area. A mass of warm water may have washed some clam #larvae toward #SantaBarbara.
