Musculoskeletal organization in seahorse. High resolution 3D reconstructions of CT-data on the caudal part of the tail in seahorses (vertical body posture, prehensile tail lacking a tail fin), represented by Hippocampus reidi. (A) Reconstruction of the caudal skeletal part of the tail (dermal plates in grey, vertebrae in blue); detail shows a lateral view of the caudal spine on the dorsal plates fitting into an anterior groove on the subsequent plate, (B-C) Reconstruction of the parallel myoseptal organization (dermal plates in grey, vertebrae in blue, myosepta in different bright colours), from (B) a medial viewpoint with vertebrae removed and (C) a lateral viewpoint with dermal plates removed.
