Transport of Dungeness crab Cancer magister megalopae into Glacier Bay, Alaska [PDF]

open access: yesMarine Ecology Progress Series, 2008
Larval behaviors and physical forcing mechanisms contributing to the transport of Dun- geness crab Cancer magister megalopae into inlets have been determined for many areas along the coastlines of Washington, Oregon and California, but have never been examined in Alaska. In 2004 and 2005, we observed transport of C.

Tolerance of Hyas araneus zoea I larvae to elevated seawater PCO2 despite elevated metabolic costs [PDF]

open access: yes, 2012
Early life stages of marine crustaceans respond sensitively to elevated seawater P CO 2 . However, the underlying physiological mechanisms have not been studied well. We therefore investigated the effects of elevated seawater P CO 2 on oxygen consumption,

Intraspecific interactions in the mangrove crab Ucides cordatus (Decapoda: Ocypodidae) during the metamorphosis and post-metamorphosis periods under laboratory conditions

open access: yesZoologia (Curitiba), 2011
Current efforts for restocking natural populations of the mangrove crab Ucides cordatus (Linnaeus, 1763) in Brazil have focused on developing a methodology for stimulating the metamorphosis of U. cordatus larvae at a large scale.

Behavioural Response Thresholds in New Zealand Crab Megalopae to Ambient Underwater Sound

open access: yesPLoS ONE, 2011
A small number of studies have demonstrated that settlement stage decapod crustaceans are able to detect and exhibit swimming, settlement and metamorphosis responses to ambient underwater sound emanating from coastal reefs. However, the intensity of the acoustic cue required to initiate the settlement and metamorphosis response, and therefore the ...

The morphology of the foregut of larvae and postlarva of Sesarma curacaoense De Man, 1892: a species with facultative lecithotrophy during larval development A morfologia do estômago de larvas e pós-larvas de Sesarma curacaoense De Man, 1892: uma espécie com desenvolvimento larval lecitotrófico facultativo

open access: yesActa Amazonica, 2006
Previous study on the resistance of larvae of Sesarma curacaoense submitted to starvation has revealed a facultative lecithotrophy during zoeal stages, but megalopa and first juvenile stages are exclusively feeding stages. In the present study, the gross

Diversity of hippoidean crabs - considering ontogeny, quantifiable morphology, and phenotypic plasticity

open access: yesNauplius, 2021
Representatives of Hippoidea, often called sand crabs or mole crabs, are an ingroup of Anomala. These marine crustaceans inhabit the tropical and subtropical coasts of the world, yet some also appear in temperate climates.

Larval Development of the New Zealand Deep Water Scampi, Metanephrops challengeri (Balss, 1914) (Decapoda: Nephropidae)

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.
The New Zealand scampi, Metanephrops challengeri, is a lobster species which has an extensive distribution on much of the continental shelf and slopes around the country in depths between 140 and 640 m. This species is important ecologically, and forms the basis of a valuable commercial fishery.

Larval development of Cyrtograpsus affinis (Dana) (Decapoda, Brachyura, Varunidae) from Río de la Plata estuary, reared in the laboratory

open access: yesScientia Marina, 2000
The complete larval development of the crab Cyrtograpsus affinis (Brachyura, Varunidae) was obtained by culture in the laboratory. Five zoeal stages, the megalopa and the first crab are described and illustrated. Larval development from hatching to first

The Role of Adult Fiddler Crab Environmental Acoustic Cues and Chemical Cues in Stimulating Molting of Field-Caught Megalopae [PDF]

open access: yes, 2017
In mid-Atlantic estuaries, three fiddler crab species, Uca pugilator, Uca pugnax and Uca minax co-occur, with their adults occupying different habitat types distinguished by salinity and sediment size.

Temperature‐induced Effects on Ecdysis Frequency, Feeding, and Growth Response of Gazami (Portunus trituberculatus) Crablets

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Gazami (Portunus trituberculatus) is a key species in stock enhancement programs in Japan. Recently, a severe decline in the Western Japan population has been observed, emphasizing the need for improvements in these programs. This study aimed to evaluate the effects of temperature on Gazami crablets under hatchery conditions, focusing on ...
