Stikine River (Delta Sites).--We documented breeding activity at Cheliped
Bay for both Wood Frogs and Columbia Spotted Frogs, but we failed to verify the presence of Western Toads at this site.
loimicola in: carapace branchial margins distinctly convergent posteriorly; median lobe of third thoracic sternite absent; and dorso-anterior margin of carpus of larger cheliped
more gently and constantly convex on entire length.

No abnormality was observed in cheliped
abnormality in P.
Although, males reveal variation in shape evidencing major functional branchial, gut, and cardiac areas (Figure 2(a)), males presented reduction of the points related to hiatus distance of MC (landmarks 3 and 4) and a sturdy cheliped
manus, evidenced by vector displacement of the landmarks in the posterior and inferior margin of the MC.
While the general descriptions were similar for each behavioral level, there were modified classifications in areas described in holding an opponent as a "do-see-do," which relates to a dance term, where we considered this behavior as a dismemberment grasp since they would try to twist the others cheliped
Similarly, Wasson & Lyon (2005) found that although female porcelain crabs are more likely to autotomize a cheliped
, compared with males, this gender difference disappears when claw size is taken into account, because females have smaller chelipeds
compared to males.
THE EFFECT THE SIZE OF THE MALE'S LARGE CHELIPED
HAS ON THE REPRODUCTION PATTERNS OF FIDDLER CRABS
Specifically we were interested in determining whether the larger cheliped
Moreover, individuals occupying open marsh areas spent significantly more time eliciting reproductive behaviors such as cheliped
Atyid shrimps in control treatments were observed to systematically scrape rock surfaces with their pereiopods, followed by expansion and rapid closure of their cheliped
fans against the substratum surface.
Homarus travisensis, from the Fredericksburg Group of Travis County, Texas, is known only from a single cheliped
Other indicators such as the presence of mating depressions, presence of sperm plug, cheliped
morphology, and being physically engaged in mating were the least favored methods of functional maturity determination (each with a usage percentage of less than 10%) (Fig.
Geometric morphometric techniques were used to evaluate morphological variation in shape and size of the carapace and right cheliped
