Figure 7From: Functional modifications associated with gastrointestinal tract organogenesis during metamorphosis in Atlantic halibut (Hippoglossus hippoglossus)GI-tract motility in Atlantic halibut larvae at stage 6 and 9. Retrograde and anterograde wave movements (propagating contractions) are indicated by a dashed line. These waves occur from area A to B; and from pyloric sphincter (represented by two red arrows*) to area B and vice-versa. A and B represent the main areas where phasic contractions occur. st: stomach/presumptive stomach; mg1: midgut region 1; mg2: midgut region 2; hg: hindgut; r: rectal area.
