Fig. 5From: Fine structural characteristics of the chorionic microspheres on the egg surface of the orb web spider Trichonephila clavataBox plot comparing the diameter distribution in the chorion surface, outer surface, and silk. The median is indicated by a line, while the upper and lower quartiles are enclosed by boxes. Whiskers represent the diameter range. The mean diameter values (2329 nm, 1692 nm, and 1594 nm, respectively) of the 500 spheres calculated are marked with X. Statistical significance is denoted as ** p < 0.05 and *** p < 0.001"Back to article page
