Wood Frog eggs were observed at
Cheliped Bay in May of 2012 and Columbia Spotted Frog eggs were observed at this site in May of 2014.
Smaller
cheliped with setation similar to that of larger
cheliped.
uncinatus was observed holding the head of a frog in its
cheliped above the water surface and then feeding on it (Fig.
Intraspecific behaviors and major
cheliped sexual dimorphism in three congeneric callianassid shrimp.
Cheliped abnormalityOnly one male crab of 98 mm SCW had rightcheliped bent outward as shown in Figures 5A and B.
The body areas and structures analysed were the anterior region of cephalothorax (AR), carapace dorsal area (C), and the outer face of major
cheliped (MC).
The
cheliped (and in fact all the legs) comprise seven segments, coxa, basis, ischium, merus, carpus, propodus and dactylus in that order, not four as stated.
Typically, the encounters escalate from visual threats of defense posturing to actual physical confrontations that include
cheliped grasping and more aggressive behaviors where one will try to dismember or even kill another individual.
Stocking density affects the growth, survival, and
cheliped injuries of third instars of narrow-clawed crayfish, Astacus leptodactylus eschscholtz, 1823 juveniles.
Aggressive interactions were characterized by the extension of both
chelipeds, and
cheliped embracing or grasping.
(Porcellanidae), porcelain crabs, increased body size is associated with less reliance on
cheliped autotomy as an escape mechanism, and greater reliance on struggling and pinching the predator with the
chelipeds (Wasson & Lyon 2005).
When a hermit crab is tucked into a shell it is fully protected by folding a
cheliped completely across the opening.
