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

Parthenogenesis in a whitetip reef shark Triaenodon obesus involves a reduction in ploidy
Journal of Fish Biology, 2014Genetic 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.

Mitochondrial DNA Part A, 2014
The complete mitochondrial genome of the whitetip reef shark Triaenodon obesus is determined in this study. It is 16,700 bp in length, with the typical gene composition, arrangement and transcriptional orientation in vertebrates. The overall base composition is 31.4% A, 25.8% C, 13.2% G and 29.7% T. Two start codons and two stop codons are found in the

Serum corticosterone concentrations in immature captive whitetip reef sharks, Triaenodon obesus
Journal of Experimental Zoology, 1993AbstractSerum concentrations of the steroid hormone corticosterone were monitored over a four‐year period in two male and two female immature captive whitetip reef sharks, Triaenodon obesus. Corticosterone concentrations in the serum ranged from 69–999 pg/ml (319.8 ± 31.9; n = 36) for males and 3–246 pg/ml (116.0 ± 15.1; n = 32) for females.

ABSTRACT Four observations of what was probably a single vagrant adult female whitetip reef shark Triaenodon obesus were made at Raoul and Meyer Islands, Kermadec Islands, New Zealand, over a 12 month period in 2014/15.

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.

At Steinhart Aquarium between December 2001 and July 2003 four litters of Whitetip reef sharks Triaenodon obesus were born to two ♀♀ producing at least 13 pups. Mean gestation period, estimated from the first appearance of mating wounds on the ♀ to parturition, was 387 ± 33·7 days (mean ± SD; n= 3).
