[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 John Thomas sign, [1] also known as the Throckmorton sign, [2] is a slang or joke term used in the field of radiology. It refers to the position of a penis as it relates to pathology on an X-ray of a pelvis. When the penis (visible on the X-ray as a shadow) points towards the same side as a unilateral medical condition such as a broken bone ...
A female hip will have a pronounced ridge on this face while a male hip will have a broad flat surface. This criterion is the least distinct of those that Phenice describes, with the highest similarity in male and female examples. It should only be relied upon in conjunction with the other two features. [1]
By eating the algae off of other fish, the blue tang serve as cleaners for them. [2] With the decline in the Diadema antillarum population, the blue tang population increased since the algal resources that the two animals usually competed for were more abundant. [8] Juvenile blue tangs eat continuously and feed heavily.
Blue tang have ventral spikes, which has the added benefit to the parrotfish of wielding away predators. The schools are typically composed of 50 to 400 blue tang with up to 17 midnight parrotfish, although a majority of schools include 1 or 2 parrotfish. Both blue tang and parrotfish compete with damselfish for algae, and the co-schooling ...
This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
As part of a laparoscopy, a blue dye solution (methylene blue or indigo carmine) is introduced into the uterine cavity. The dye solution will help determine if the fallopian tubes are open or blocked. If the fallopian tubes are open, the dye solution will enter and drain out into the pelvic cavity through the ends of the tubes.
