Despite the fact that researchers have been studying reef and lagoon flat habitats of the Atoll since 2003, lemon sharks were first observed in 2010, suggesting a recent colonization event. To date, only juveniles and sub-adult sharks have been observed.

  • (Elasmobranchii: Carcharhiniformes) in the Pliocene of the Mediterranean Sea
    N. Jb. Geol. Paläont. Abh. 295/2 (2020), 129–139 Article E Stuttgart, February 2020 The extinct catshark Pachyscyllium distans (PROBST, 1879) (Elasmobranchii: Carcharhiniformes) in the Pliocene of the Mediterranean Sea Alberto Collareta, Marco Merella, Frederik H. Mollen, Simone Casati, and Andrea Di Cencio With 4 figures and 1 table Abstract: Sharks assigned to the carcharhiniform family Scyliorhinidae account for about 160 extant species placed in 18 genera. Most living scyliorhinids are small- to medium-sized ground sharks provided with cat- like eyes and nasal barbels similar to whiskers; hence their vernacular name, “cat- sharks”. Living catsharks mostly inhabit deep or rather deep waters of the warm and temperate seas worldwide, foraging on small fishes and inverterbates. In the present paper, we report on a lateral tooth of Scyliorhinidae collected from a clay pit at Certaldo (central Italy), where marine mudstones belonging to the famously fossiliferous Pliocene successions of Tuscany are exposed. This catshark specimen represents the second bona fide record of the extinct premontreine species Pachyscyllium distans in the Pliocene of the Mediterranean Sea, as well as the geologically youngest confirmed occurrence of this species worldwide. In the Mediterranean Pliocene, P. distans thus coexisted with the similar but distinct species Pachyscyllium dachiardii. After having been widespread in Northern Atlantic, Paratethyan, and Mediterranean waters in Miocene times, P. distans became confined to the Mediterranean Sea during the Pliocene. Therefore, similar to what has recently been suggested for P. dachiardii, we hypothesise that the range of P. distans contracted southward as colder conditions took hold in the Northern Hemisphere. The eventual extinction of P.

  • Acoustic Tracking of Bigeye Thresher Shark Alopias Superciliosus in the Eastern Pacific Ocean
    MARINE ECOLOGY PROGRESS SERIES Vol. 265: 255–261, 2003 Published December 31 Mar Ecol Prog Ser Acoustic tracking of bigeye thresher shark Alopias superciliosus in the eastern Pacific Ocean Hideki Nakano*, Hiroaki Matsunaga, Hiroaki Okamoto, Makoto Okazaki National Research Institute of Far Seas Fisheries, 5-7-1 Shimizu-Orido, Shizuoka 424-8633, Japan ABSTRACT: Acoustic telemetry was used to identify the short-term horizontal and vertical movement patterns of the bigeye thresher shark Alopias superciliosus in the eastern tropical Pacific Ocean dur- ing the summer of 1996. Two immature female sharks, 175 and 124 cm PCL (precaudal length), were tracked for 96 and 70 h, respectively, demonstrating very distinct crepuscular vertical migrations sim- ilar to those reported for the megamouth shark. The bigeye threshers stayed at 200 to 500 m depth during the day and at 80 to 130 m at night. The deepest dive extends the known depth distribution of the species to 723 m. No ‘fly-glide’ behavior (rapid ascents followed by slower acute-angled descents) was observed for the 2 sharks. However, the opposite behavioral pattern of slow ascents and rela- tively rapid descents during the night was observed. Since bigeye threshers have large eyes extend- ing upwards onto the dorsal surface of the cranium, it may be more efficient for them to hunt prey which are highlighted against the sea surface from below. Estimated mean swimming speed over the ground ranged from 1.32 to 2.02 km h–1, similar to swordfish and megamouth sharks, and slower than that reported for tunas, billfishes, and other pelagic sharks.
