A theoretical composite model for population sex-specific shell size dynamics in Strombidae (Gastropoda, Neostromboidae)

Estimation of Individual Growth of Titanostrombus galeatus (Strombidae: Gastropoda) at Punta Maldonado, a Fishing Community in Tropical Eastern Pacific, Mexico

“…The maximum size and mean SL recorded in females were larger than in males; these behaviors have been observed in other Strombidae species (Chang & Camarena 2020, Haumahu & Uneputty 2021), and some authors mention that Strombidae females are larger due to an evolutionary directional force driven by fecundity (Maxwell et al 2021). In some species of cephalopods, females reach a larger size to maximize their reproductive success (ability to develop and store oocytes) (Emery et al 2001).…”

Asymmetry of eye peduncle length in Euprotomus iredalei (Abbott, 1960) (Mollusca: Neostromboidae: Strombidae)

“…There is widespread sexual dimorphism in the stromboidean complex in shell size, with larger females than males [12][13][14][15][16][17][18][19]. Furthermore, sexual dimorphism is known in relative body size, some organs and the radula [20][21][22].…”

Population structure and morphology of Canarium (Canarium) incisum and Canarium (Canarium) esculentum (Mollusca: Neostromboidae: Strombidae) from the Philippines with preliminary notes on aperture colouration based on DArTseq data

“…However, few studies have sought to understand the population structures of these taxa (Maxwell et al, 2022).…”

“…Some members of the Strombidae express sexually dimorphic characteristics in both physiology and shell morphometrics (Abbott, 1949(Abbott, , 1960(Abbott, , 1961Reed, 1993a;Mutlu 2004;Maxwell, Rowell, et al, 2020a;Maxwell, Rymer, et al, 2021b, Maxwell et al, 2022. While the phenomenon of sex-ratio bias is reported from numerous members of the Strombidae, this may simply be an artefact of aggregation and sampling size (Maxwell et al, 2017;Maxwell, Rymer, et al, 2021b).…”

“…This diversity is emphasised with the recent taxonomic revisions of many groups in this region, with many new species having recently been circumscribed within the clade Neostromboidae Maxwell, Dekkers, et al, 2019a, including Rostellariidae (Morrison, 2008), Seraphsidae Jung, 1974 (Poppe & Tagaro, 2016; Dekkers et al, 2019; Maxwell et al, 2021a) and Strombidae Rafinesque, 1815 (Dekkers et al, 2021). However, few studies have sought to understand the population structures of these taxa (Maxwell et al, 2022).…”
