Typically, porcellanid crabs exhibit sexual dimorphism, where males and females may have different sizes and physical characteristics. This can be influenced by factors such as habitat, food availability, and reproductive behaviours. Detailed studies of specific species and populations are necessary to provide accurate and comprehensive information about the size distributions and sex ratios of intertidal porcellanid crabs. In the present study, we describe size distributions and sex ratios of some intertidal porcellanid crabs, <i>Petrolisthes violaceus</i>, <i>Petrolisthes granulosus</i>, <i>Petrolisthes tuberculatus</i> and <i>Allopetrolisthes punctatus</i>, collected from northern Chile, as well as the probability of sexual maturity of females at a given size (0.66&nbsp;mm). The results within species for <i>P. granulosus</i> and <i>P. violaceus</i> did not show significant differences in sex ratio, whereas for sex-size structure these two species displayed significant differences. Similar results were observed in populations of <i>P. tuberculatus</i> and <i>A. punctatus</i>. Ecological and reproductive topics are discussed.","AbstractOtherLang":"La proporción de sexos y el tamaño corporal por sexo en las poblaciones de cangrejos porcelánidos intermareales varían de una especie a otra y está relacionado con la expresión genética específica y el mecanismo molecular subyacente que aún se desconoce en gran medida (Kasimatis et al., 2021). Normalmente, los cangrejos porcelánidos presentan dimorfismo sexual, donde machos y hembras pueden tener diferentes tamaños y características físicas. Esto puede verse influenciado por factores como el hábitat, la disponibilidad de alimentos y los comportamientos reproductivos. Se necesitan estudios detallados de especies y poblaciones específicas para proporcionar información precisa y completa sobre la distribución de tamaños y la proporción de sexos de los cangrejos porcelánidos intermareales. En el presente estudio describimos las distribuciones de tamaño y las proporciones de sexos de algunos cangrejos porcelánidos intermareales, <i>Petrolisthes violaceus</i>, <i>Petrolisthes granulosus</i>, <i>Petrolisthes tuberculatus</i> y <i>Allopetrolisthes punctatus</i>, recolectados de norte de Chile, y la probabilidad de madurez sexual de las hembras a una determinada talla (0.66&nbsp;mm). Los resultados dentro de las especies para <i>P. granulosus</i> y <i>P. violaceus</i> no mostraron diferencias significativas en la proporción de sexos, mientras que para la estructura sexo-tamaño denotaron diferencias significativas. Se observaron resultados similares en poblaciones de <i>P. tuberculatus</i> y <i>A. punctatus</i>. Se discuten temas ecológicos y reproductivos.","BibLvlCode":"AS","StandardTitle":"Sex ratios and body sizes per sex in populations of some intertidal porcellanid crabs, collected from northern Chile (Anomura, Galatheoidea, Porcellanidae)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-08-08 01:33:19.193757","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-08-01","DateCreate":"2025-08-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1163/15685403-bja10452"},"refs":null,"anarec":{"AnaID":410327,"PubliDate":2025,"Pagination":"313-324","XtraPublOfAnaID":null,"ISBN":null,"Volume":"98","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42595,"SerRR":"Crustaceana.
