Sea World has successfully? created a pre-determined female Bottlenose Dolphin through AI and sex selection techniques.

there is no excess of males, at least in the European population (I`m not sure about the US).
Well, bottle-nose dolphins are hardly critically endangered and african elephants neither.
First of all where did I say that bottle-nosed dolphins and African elephants are endangered?.
And black rhinos breed well through natural breeding and at the moment, there is no excess of males, at least in the European population (I`m not sure about the US). They don`t live in all-female-herds anyway.
My point in regards to AI is that this tool can be used World wide helping the breeding of rare animals, if the European black rhino breeding program is doing well without using any AI that good for them But as In Australia we only have ONE breeding herd so if we can use AI bringing in a new bloodline instead of shipping a live animal that has to be a plus in my book, not every country has big groups of animals such as the EEP & the SSP. In regards to black rhinos living in all female groups, again who said they did?, my point again with any rare species of animals numbers can be built up faster with more females in the population than males can it not?.
I have seen zoos such as Port Lympne keeping a number of female Black rhinos togeather without to much problems and they have one of the best breeding records for the species around.
Moving rhnos isn`t without risk neither, certainly, but there result is usually a breeding pair that will breed naturally for many years - without additional risk. A.I. and semen collection is usually needed more then once just to archieve ONE pregnancy, and 1-2 years later, you can start the whole stressful and expensive procedure again (and so on). In Dvur Kralove, the AI procedures on the rarest species of the world, the northerrn whito rhino, have been stopped for that very reason - too dangerous to continue to knock down the animals every few months.
