“…Unfortunately, there are no studies of titanium accumulation by sharks in the study area. The concentration of Ti in this study was shown to be lower compared to the study reported by Hauser-Davis et al [31] on P. glauca from the Western North Atlantic Ocean and Ju et al [34] on megamouth sharks (Megachasma pelagios) from Taiwan. However, higher than a study reported by Bouchoucha et al [35] from the Western Mediterranean Sea on commercial fishes.…”

“…However, higher than a study reported by Bouchoucha et al [35] from the Western Mediterranean Sea on commercial fishes. Ju et al [34] reported that a high concentration of Ti on M. pelagios is probably because of the feeding habits of planktivorous compared to carnivorous sharks. Titanium has been reported to be associated with marine microalgae (diatoms and dinoflagellates) in high concentrations (more than 1,000 μg/g dry weight) [36].…”

Metals accumulation in threatened sharks’ meat represents a global health issue. The objective of the current study was to measure the concentration of six metals (Li, Ti, Ni, Cd, As, and Pb) using ICP-MS in threatened sharks’ meat of Rhizoprionodon acutus, Squalus hemipinnis, and Sphyrna lewini from Binuangeun Fish Auction in Lebak, Banten, Indonesia. The results showed that the concentration of Ni, Li, Cd, and Pb was below the acceptable levels for food sources for human consumption, except for As concentration (more than 30 fold higher). This study showed high levels of Ti concentration in all threatened sharks' meat. Overall, this study shows that an accumulation of Ti in sharks' meat should be considered a risk to the health of seafood consumers.

“…The latest indicated that none of the analyzed species is edible, except for pelagic thresher ( Alopias pelagicus ), limited to one portion per week. However, it is well known that the consumption of shark meat represents a serious human health risk for the populations [46] , [60] , [90] , as this fish species has a slow-growing and tends to accumulate a large amount of MeHg [34] .…”

“…Afterward, the Taiwan Fisheries Agency announced a ban fishing management measure on M. pelagios on 10 November 2020 for conservation purposes (the catching is forbidden; fisherman have to release the shark whether it is dead or alive); however, further effectiveness and study remain to be elucidated. Studies to date have included its morphology, movement, molecular biology, physiology, and chemical analysis [17][18][19][20][21][22][23][24][25].…”

The megamouth shark (Megachasma pelagios) is one of the rarest shark species in the three oceans, and its biological and fishery information is still very limited. A total of 261 landing/stranding records were examined, including 132 females, 87 males, and 42 sex unknown individuals, to provide the most detailed information on global megamouth shark records, and the spatial–temporal distribution of M. pelagios was inferenced from these records. The vertical distribution of M. pelagios ranged 0–1203 m in depth, and immature individuals were mostly found in the waters shallower than 200 m. Mature individuals are not only able to dive deeper, but also move to higher latitude waters. The majority of M. pelagios are found in the western North Pacific Ocean (>5° N). The Indian and Atlantic Oceans are the potential nursery areas for this species, immature individuals are mainly found in Indonesia and Philippine waters. Large individuals tend to move towards higher latitude waters (>15° N) for foraging and growth from April to August. Sexual segregation of M. pelagios is found, females tend to move to higher latitude waters (>30° N) in the western North Pacific Ocean, but males may move across the North Pacific Ocean.
