Where are larvae of the vermetid
gastropod Dendropoma maximum on the continuum of larval nutritional strategies?
Here we describe an unusual case of reproduction of a vermetid
gastropod that combines nurse eggs, developmental arrests, sibling cannibalism, and brood reduction.
What they discovered was that these bars were preserved by nearly 12 feet of vermetid
gastropods, also known as worm snails.
molluscs (Serpulorbis sp.) were abundant on benthic substrata at El Frances, Punta Freedy, Bahia Tres Puntas, and Sal si Puedes (Fig.
Other macrofossils present, or locally characteristic, within this formation are orbitolinids, nautiloids, brachiopods, vermetid
gastropods, solitary corals, serpulids, echinoids, Plicatula placunea and Lithocodium aggregatum (e.g., Bover-Arnal et al., 2010; 2011).
gastropod Dendropoma maxima, Sowerby 1825 (Vermetidae, Littorinimorpha, Gastropoda) is a dominant, very abundant encrusting species of outer tropical reefs and widespread throughout the IndoPacific [1-3].
In Brazil, most of the reefs present tiny calcareous formations that grow on sandstone rocks whose main bioconstructors are encrusting calcareous algae, vermetid
molluscs and few corals (Maida and Ferreira, 1997; Castro and Pires, 2001).
In substrate-cemented mollusks, such as vermetid
gastropods, the larval shell is preserved.
Polychaete cryptofauna from rims of similar intertidal vermetid
reefs on the Mediterranean coast of Israel and in the Gulf of Elat: Syllidae and Eusyllinae (Polychaeta: Syllidae).
Biogenic reefs that provide important ecosystem services such as habitat for other organisms include not only tropical coral reefs but also temperate reefs constructed by oysters (Bahr and Lanier, 1981; Lenihan et al., 2001), polychaetes like Petaloproctus (Wilson, 1979; Reise, 1982), and vermetid
gastropods (Safriel, 1975).
In 1999, a 32.5 mm snail was observed at HMLR on a rocky reef and a second snail (31.6 mm) collected at McAbee Beach was eating the vermetid
snail Petaloconchus montereyensis.
Reefs are constructed by various kinds of organisms including, among others, oysters, vermetid
gastropods, serpulid polychaetes, calcifying algae (in particular red algae or Rhodophytes), hydrozoans, and corals.
