Tissue Sample Evidence

-- The **** fibers sampled from the carcass were rigid, needle-like structures that tapered toward both ends and had a translucent light-brown color (Kimura, Fujii, and others 1978). Such features are characteristic of ceratotrichia, the cartilaginous fibers of shark fin rays. Abe (1978) found that the carcass fibers and known ceratotrichia from a basking shark "resembled each other remarkably."

-- Gross amino acid analysis of the carcass samples gave results that closely matched elastoidin from a known basking shark. Elastoidin is a collagenous protein known only from sharks and rays (not reptiles or even other fish). The match was especially impressive when known basking shark elastoidin was treated with an antiseptic sodium hypochlorite (NaClO) solution, as were the Zuiyo-maru samples (Obata and Tomoda 1978, p 52; Omura, Mochizuki, and Kamiya 1978, p 58). The correspondence was virtually identical on all 20 amino acids tested (Table 1). In discussing this "striking similarity," Kimura, Fujii, and others (1978, p 72) noted that a statistical test called the "difference index (DI)" gave the extremely low value of .95 indicating a tight match. They also noted that the high tryosine content (43 and 41 residues for the samples) is especially characteristic of shark elastoidin as compared with other collagens, which typically have 5 or less residues. ceratotrichia.
