Gastropod - Reproduction, Life Cycles: The fertilized egg of gastropods hatches into a free-swimming form (trochophore larva).

Helix comprises large land snails species, with shell diameter of 2–6 cm. The shell is globular to conical, with five darker bands that may be reduced or fuse together.

The following cladogram is an overview of the main clades of gastropods based on the taxonomy of Bouchet & Rocroi (2005), with families that contain freshwater species marked in boldface: (Some of the highlighted families consist entirely of freshwater species, but some of them also contain, or even mainly consist of, marine species.) Apr 12, 2022 · The gastropod shells of the garden snail are dull and unnoticeable. The shell's surface is frequently carved. Small arthropods prey on the tiny species [less than 0.1 in (3 mm) in diameter]. The snail's natural tendency to retreat into its shell is useless since the predator merely pursues the snail into its shell. Specifically, we hypothesized that a) native gastropod species consume the seeds from all tested plant species in equal numbers (independent from seed or fruit type), b) the voracious invasive alien slug A. lusitanicus – similarly to its herbivore behaviour – consumes a higher amount of seeds than native gastropods, and that c) seed ...Gastropods are the second largest class of animals (after the Insecta)—with 40,000–90,000 living species and at least 13,000 extant and fossil genera (Ponder and Lindberg, 2020)—and are also one of the most evolutionarily successful groups in the variety of ecosystems and habitats that they occupy.National Geographic has been at the forefront of conservation efforts around the world for over a century.
