Ocular tentacle regeneration and associated malformations in Stramonita haemastoma (Gastropoda: Muricidae)

Ocular tentacle malformation in Deroceras reticulatum (Mollusca: Gastropoda: Agriolimacidae)

“…The malformation observed in D. reticulatum of San Pedro is not the most common type, since amputations, bifurcations or partial fusions of the tentacles are usually detected as mentioned above (Römer, 1903;Wächtler, 1929;Chetail, 1958;Jackiewicz, 1969;El Ayari et al, 2018). Although only one individual with this malformation was registered, it is important to document their registration, which is the first to be mentioned in South America.…”

“…Malformations in animals have been cited in several cases, particularly in gastropod molluscs, mainly linked to cases of parasitism and exposure to pollutants (molluscicides and chemicals). These malformations can affect their reproductive system, mantle, foot or ocular tentacles (Simroth, 1905;Boettger, 1956;Wiktorowa, 1962;Jackiewicz et al, 1998;Barroso et al, 2000;Lahbib et al, 2008;Sawasdee & Kohler, 2009;El Ayari et al, 2018). The abnormal variations developed in the tentacles of gastropods are remarkable, and occur under both natural and experimental conditions.…”
