Fig. 2. Structural treatments 1-4 used in bending experiments. (A) Cross-sectional
view of body axis at 0.37 L from rostrum. The body segment (1) was
serially dissected (depicted from left to right) with the skin removed (2),
then the muscle removed (leaving the notochord) (3), and finally the outer
fibrous sheath removed (4). (B) Width of the body. (C) Cross-sectional area of
the body. (D) Second moment of area I of the body. Asterisks denote
significant differences (P<0.05) between adjacent means as
determined using planned constrasts in a repeated-measures ANOVA (N=8
individual hagfish).
