The reproduction and larval development of the sea limpet Lottia persona (Rathke, 1833) were investigated in vitro for the first time. The limpets breed in late July; they have external fertilization and a pelagic lecithotrophic type of development. The larval shell is transparent, symmetrical, and bottle-shaped, with well-pronounced lateral fossae and a(More)
Within Gastropoda, limpets (Patellogastropoda) are considered the most basal branching taxon and its representatives are thus crucial for research into evolutionary questions. Here, we describe the development of the neuromuscular system in Lottia cf. kogamogai. In trochophore larvae, first serotonin-like immunoreactivity (lir) appears in the apical organ(More)
The larval morphology of the gastropod Cryptonatica janthostoma inhabiting the Northwest Pacific was described for the first time. Hatched planktotrophic veligers of C. janthostoma had shells 250 μm in height with 0.8 whorls, a bilobate velum with a dark brown pigmentation band shaped along its edge, pair of eye spots, tentacles and statocysts. The surface(More)
A putative new limpet species (Patellogastropoda) from the Sea of Japan is revealed by molecular genetic analyses using the mitochondrial markers 16S rRNA and cytochrome c oxidase subunit I (CO1), as well as the DNA marker 18S rRNA. Our data indicate that the limpet, collected in the Peter the Great Bay (Russian Federation), is not, as its morphology(More)
Reproduction and larval development of the limpet Limalepeta lima (Dall, 1918) were studied under laboratory conditions for the first time. L. lima breeds in early July; it exhibits external fertilization and the pelagic lecithotrophic type of development. Larvae, juvenile, and adult specimens have different shell sculptures. Development from fertilization(More)
The larval development and microsculpture of the shell of the prosobranch gastropod Epheria turrita were studied in laboratory conditions. The mollusk laid egg masses on the thalli of macrophytes. An egg mass looked like a flattened ring or a spiral, from 1 up to 6 mm in diameter. The number of eggs in egg masses depended on their size and varied from(More)
