The animal either filter feeds with long setae borne from the maxilliped palps, or scavenges by chopping up flesh with the second maxilliped and further shredding with the mandibles. This has been proposed by Fields (1983) for some groups of marine invertebrates but, contrary to our results, this author suggests that crustaceans do not use the octopine pathway. The range of experimental temperatures was chosen to cover the average yearly temperatures for the collection area and some temperatures outside of the normal range of Coliumo Bay. and transmitted securely.

Eclosion in Petrolisthes armatus (Gibbes) (Anomura, Porcellanidae). Accordingly, they show important adaptive capacities at physiological and biochemical levels (Newell, 1979; Spaargaren, 1982; Burgren and Putzer, 1985; Meyer-Rochow and Meha, 1994; Stillman and Somero, 1996). Respiration rates were estimated from the differences in oxygen content between incubation periods. Adaptation to temperature stress and aerial exposure in congeneric species of intertidal porcelain crabs (genus. High enzymatic activity of LDH was found in muscle tissue. Organisms living in the intertidal zone are subjected to important fluctuations in temperature, salinity, dissolved oxygen, and other physical parameters (Morris and Taylor, 1983; Pellegrino, 1984). size Or state Of adaptation, a stratified random sampling s) tern was designed. At the study sites, the invasive crab Petrolisthes elongatus, possibly introduced via live oyster trade during the late 1800s, reaches high densities underneath boulders and among cobbles at low . The water placed in four jars had previously been filtered using 0.5 mm polypropylene-nylon filters (Cuno) and sterilized with ultraviolet light for 1520 min.
