Geometric morphometric techniques were used to evaluate morphological variation in shape and size of the carapace
and right cheliped propodus.
is heavily armored, dorsoventrally flattened and relatively rough, composed of numerous small tubercles that offer favorable conditions as a biogenic surface for the settlement and growth of the oyster.
platensis in La Plata River basin (Giri & Collins, 2004); morphologic variation of adult males carapaces
Figure 3 (a,b,c,d,e) presents the results of fourier transform infrared spectroscopy for chitosan samples isolated from shrimp head waste, crab leg shells, crab claws crab carapaces
and pure chitosan, respectively.
Females were longer than males among the individuals with CL less than 4 cm whereas males were larger than females in specimens with longer carapace
ESD is characterized by severe, deep erosions of the cuticle that extend laterally and, more characteristic of this disease than others, spreads irregularly over the dorsal carapace
of the animal (Smolowitz et al.
The differences in sexual dimorphism in each species were analyzed using ANCOVA, with the straight carapace
length as a covariable in order to rule out the effect of size on form (Bonnet et al.
With the turtles at the modern pond sites, the carapaces
were either up or down in nearly equal ratios (see Tables 1 and 2).
I have also learned that the encrusters on horseshoe crabs have preferred orientations and locations on the carapace
," she continued.
Researchers in New Jersey recently examined 53 living wood turtles that had been injured by predators, and 27 of them were missing limbs while 11 others had mutilated carapaces
olivacea hosted numerous hydrozoans growing in association with the macroalgae Ulva on several carapace
scutes where sandy areas had accrued (Case study 2 and 3).
The shape of hatchlings was investigated based on the morphometric geometric analysis of carapace
