Mating in the reef white-tip shark Triaenodon obesus

Marine Biology, 1985
Mating reef white-tip sharks, Triaenodon obesus, were observed and photographed in shallow waters of the Hawaiian Islands. The sharks copulated in a stationary parallel orientation with their heads on the bottom and bodies angled upwards approximately 45° into the water column.

Serum T4 and serum T3 concentrations in immature captive whitetip reef sharks,Triaenodon obesus

The Journal of Experimental Zoology, 1999
Serum T(3) (3,5,3' triiodothyronine) and serum T(4) (thyroxine) concentrations were repetitively assayed by radioimmunoassay over a three-year period in two male and two female immature captive whitetip reef sharks, Triaenodon obesus. These sharks were maintained at the Waikiki Aquarium, Honolulu, Hawaii, in an open system holding pool receiving 568 ...

Oceanic dispersal in a sedentary reef shark (Triaenodon obesus): genetic evidence for extensive connectivity without a pelagic larval stage

Journal of Biogeography, 2011
AbstractAim  Most reef fishes are site‐attached, but can maintain a broad distribution through their highly dispersive larval stage. The whitetip reef shark (Triaenodon obesus) is site‐attached, yet maintains the largest Indo‐Pacific distribution of any reef shark while lacking the larval stage of bony (teleost) fishes.

Developmental Stages of Paralebion elongatus from Aquarium-Held Reef Whitetip Sharks (Triaenodon obesus) Captured in Hawaiian Waters

Journal of Parasitology, 1992
Adult male and female, nauplius 1 and 2, and preadult 1 and 2 stages of Paralebion elongatus Wilson, 1911 (Copepoda: Euryphoridae) are redescribed and described, respectively, from specimens collected from aquarium-held reef whitetip sharks (Triaenodon obesus) captured in Hawaiian waters. A circular area of villiform papillae between the frontal plates

Movements, reproductive seasonality, and fisheries interactions in the whitetip reef shark (Triaenodon obesus) from community-contributed photographs

Environmental Biology of Fishes, 2011
Despite being a common apex-level predator on coral reefs throughout the tropical Indo-Pacific, surprisingly little is known about whitetip reef shark (Triaenodon obesus) movements and biology. This study used photo-identification from community-contributed photographs to reveal patterns in movements, reproductive biology, and fisheries interactions in

Parthenogenesis in a whitetip reef shark Triaenodon obesus involves a reduction in ploidy

Journal of Fish Biology, 2014
Genetic analysis of a female whitetip reef shark Triaenodon obesus and her stillborn pup, assumed to be of parthenogenetic origin, revealed that the pup was homozygous at all 24 nuclear‐encoded microsatellites assayed, consistent with the idea that diploidy in the pup had been restored via terminal fusion.
