"Curious Clavagelle Shell, Tubular Bivalve – Marine Curiosity And Naturalia"
Very curious and rare example of a Clavagelle, tubular bivalve mollusk Aspergillum vaginiferum (Lamarck, 1818). There is little about them, and very rarely encountered in collections. This bivalve is characterized by complete tubular development, and by atrophy of the second valve, called the free valve. This is found in a residual state on the front end of the tube (see photo). On this same end we observe an anterior disc ending in numerous pores of dichotomous tubes. Brechetis attrahens (Lightfoot, 1786), clumping watering can are common but outdated synonyms. Dimensions of the shell: 15 cm in length / maximum diameter 2 cm. Origin: Indian Ocean In perfect condition, the rear end is intact. Note a hole formed in the shell post-mortem by a shellfish organism. Presented in an unsealed glass bottle at the top (a cotton pad can close the bottle for example), also available if necessary.
