It differs from other crabs in possessing long antennae; its colouring is greenish-blue. If you notice any inaccuracies, please sign in and mark papers as correct or incorrect matches. The gradient of the V/LogI curve (n) in light-adapted animals increased, which means a smaller increase in intensity is required to produce an increase in response compared to a dark-adapted animal, but there was no difference in n with regard to the different age-groups. Bars correspond to standard deviation. Similar results were reported for the porcellanid genera Petrolisthes by JONES (1977), SCELZO (1985) and OLIVEIRA & MASUNARJ (1995), and for Porcellana and Pisidia by SMALDON (1972) and SANZ (1987).

When the weight of the specimens reported by Wolvekamp and Waterman (1960) was given as wet weight, the dry weight was assumed to be 40% wet weight. We used the same homogenization method described for the determination of LDH activity in the determination of opines activities.

Keynote (Plenary) Speaker, International Council for the Exploration of the Seas (ICES) Annual Science Meeting, Riga, Latvia, September 2016. Water loss in the most terrestrial species of crabs was several times greater than terrestrial vertebrates, insects and arachnids and indirect evidence indicates that most water loss of crabs is through the integument exclusive of the gill chamber.

However, on a short-term basis, P. laevigatus can cope well with environmental or functional hypoxia because of the high activity levels of LDH and OPDH and to the presence of both enzymes in the heart. The carapace is flattened with smooth side and rear margins, width is up to 18 mm (0.71 in), and long whip-like antennae grow from the front corners, with the short . Terminal Sedation Definition, In addition, OPDH, ALPDH, and STRDH were corrected for LDH activity when this enzyme was present. Media in category "Petrolisthes elongatus" This category contains only the following file. Petrolisthes laevigatus (Gurin, 1835) is commonly found in the intertidal zone of the Chilean coast and can be found from southern Peru (12S) to southern Chile (46S) (Retamal, 1981). Unfortunately, the role of dissolved oxygen in determining the distribution patterns of porcellanids in the intertidal and subtidal environments is still not well understood (Burggren and McMahon, 1981; Jensen and Armstrong, 1991). Such capacity has been described for Petrolisthes cinctipes (see Stillman and Somero, 1996), a species inhabiting from the meso- to the supralittoral in the intertidal zone, living under rocks, in much the same environment where P. laevigatus can be found. The limited tolerance of P. laevigatus to experimental hypoxia (less than three hours) suggests the absence of the glucose-succinate pathway, because organisms generally use the lactate and opines pathways to maintain metabolic activity under hypoxic conditions and the glucose-succinate and aspartate-succinate pathways for long-term survival in hypoxic/anoxic environments (Livingstone, 1991). Petrolisthes elongatus, known as the New Zealand half crab, [2] elongated porcelain crab, blue half crab, blue false crab or simply as the half crab or false crab, [3] is a species of porcelain crab native to New Zealand..
