Paracanthurus hepatus is a species of Indo-Pacific surgeonfish.A popular fish in marine aquaria, it is the only member of the genus Paracanthurus. [2] [3] A number of common names are attributed to the species, including regal tang, palette surgeonfish, blue tang (leading to confusion with the Atlantic species Acanthurus coeruleus), royal blue tang, hippo tang, blue hippo tang, flagtail ...
The pelvis is, in general, different between the human female and male skeleton. [14] [15] Although variations exist and there may be a degree of overlap between typically male or female traits, [14] [15] the pelvis is the most dimorphic bone of the human skeleton and is therefore likely to be accurate when using it to ascertain a person's sex ...
The Phenice method is a technique of determining the sex of a human skeleton from the innominate pelvis. In the procedure, sex is determined based on three features: the ventral arc, the subpubic concavity, and the medial aspect of the ischio-pubic ramus. As a non-metric absolute method, it relies on the recognition of discrete male and female ...
Juvenile blue tangs eat continuously and feed heavily. This heavy feeding requirement is due to their poor utilization of food resources. [citation needed] The blue tang's stomach and intestinal lining are proficient at absorbing crushed cellular content, but are not very effective at processing cellulose. This digestive system inefficiency ...
The vesicouterine pouch is a fold of peritoneum over the uterus and the bladder, forming a pelvic recess. [1] It is continued over the intestinal surface and body of the uterus onto its vesical surface, which it covers as far as the junction of the body and cervix uteri, and then to the bladder.
A subpubic angle of 50–82 degrees indicates a male; an angle of 90 degrees indicates a female. [2] Other sources operate with 50–60 degrees for males and 70–90 degrees in females. [ 1 ] Women have wider hips, and thus a greater subpubic angle, in order to allow for child birth .
The powder blue tang is rarely harvested for anything other than the marine aquarium industry. It is a commonly sold fish that is moderately difficult to care for, although its popularity is easily exceeded by the regal tang and yellow tang. [citation needed] They are very prone to Cryptocaryon irritans. [6]
