Spacing and movement in the green porcelain crab Petrolisthes armatus: evidence for male competition and mate guarding

Marine and Freshwater Behaviour and Physiology, 2017
AbstractThe green porcelain crab, Petrolisthes armatus, is a common invasive species on inter-tidal oyster reefs in the South Atlantic Bight whose behavior is largely unknown. We assessed the effects of the presence of opposite-sex conspecifics on adult crab spacing at a low density to infer potential mate acquisition behaviors. Adult crabs held in all-

Petrolisthes Armatus: a Redescription of Larval Development Under Laboratory Conditions (Decapoda, Porcellanidae) 1)

Crustaceana, 1970
[Die Entwicklung von Petrolisthes armatus wird auf Grund von Laboratoriumskulturen beschrieben und vier Stadien unterschieden: Pra-Zoea, Zoea I, Zoea II und Megalopa-Stadium. Die Larven wurden in zwei Serien aufgezogen. Serie A wurde mit Artemia-Nauplien gefuttert, Serie B erhielt kein Futter.

Population biology of the green porcelain crab Petrolisthes armatus (Crustacea: Porcellanidae) in a tropical estuarine bay of northeastern Brazil

2019
The aim of this study was to investigate the population biology of the green porcelain crab Petrolisthes armatus in an estuarine area of northeastern Brazil. Individuals were monthly sampled (February 2011-January 2012) during the spring low tide. Four transects, 10 m apart from each other and perpendicular to the shoreline were delimited in the rocky ...

Petrolisthes Armatus (Gibbes, 1850) : the Development Under Laboratory Conditions of Larvae From a Pacific Specimen (Decapoda, Porcellanidae 1)

Crustaceana, 1972
[Larven, welche von einem Pazifischen Exemplar von Petrolisthes armatus stammen, wurden unter Laboratoriums-Bedingungen aufgezogen. Diese Larvenentwicklung wird beschrieben und voll abgebildet. Zoea- und Megalopa-Stadien unterscheiden sich in verschiedener Hinsicht konstant von solchen, welche fruher von einem atlantischen Exemplar derselben Art ...

Population relationships between the parasiteAporobopyrus curtatus(Richardson, 1904) (Isopoda: Bopyridae) and one of its porcelain crab hostsPetrolisthes armatus(Gibbes, 1850) (Decapoda: Porcellanidae) from Farol Island, southern Brazil

Journal of Natural History, 1998
The following aspects of population relationships between the bopyrid isopod Aporobopyrus curtatus and the porcelain crab Petrolisthes armatus were analysed: size-specific prevalence, parasitic intensity, frequency distribution of the nine groups of parasite stage or sex infesting hosts.
