Right but it is the best option that we have. They are arrurate enough for me to trust the list and raise my suspision on the ones that I question. I don't expext anybody to not make a mistake, just keep it at a minimum.
Sorry gotta disagree again, go to your LFS ask them to ID 5 Acros, try it a wholesaler, and the divers..they aren't Id'n either you know how long it would take them to collect there quota for the day if they sat there and Id'd every acro. Yes, there is some guy doing "general" id's for cities/shipping, but if you think some government official is going to be able to tell you the difference between a millipora, and a spathula, or an acanthastrea and a favia.. It ain't happening, nor are they going to spend the time to do it. 200 hard corals.. good to go, they aren't popping open every bag inspecting and resealing them. The ID system in the trade is VERY VERY Loose. Even in your stores outside of say Milli, and Tenuis, Tort, and a few broad distinct acroporas nothing really gets Id (and half the time those are wrong).
Very few people in the "retail/wholesale/sales" end of the industry can or care to ID acros. You look @ a wholesale sheet it's "red Acropora fancy and the price." Acropora B-grade and the price" "Australian Acropora and the price" "Table Acro and the price" Very very generic terms, used to describe them based on broad physical appearances. The cost of acros is 100% Dependent on the Colour vibrancy, Size, if it's wild or cultured and (sometimes generic shape ie all efflo like acros which are easy to spot usually have a similar price, as do all "delicate" type acros. The rarest most interesting species of acro still ends up in the discount bin when it turns brown.
The hobbyist/scientist are the only ones that care. The primary reasons why we hobbyist care is because we want to know is to find out where we should try to place it in our tank. High light, High flow, low light high flow, etc. (and because it's neat to know). But really when it comes to placement we have no need to know the species id. Simply look at the growth/(and if you can colour). Dense coral tons of polyp bright colours.. Upper Reef Crest. Sparse polyp distribution, deeper colours, sparse branchement placement.. Lower flow, lower light...etc.
Personally I've spent A LOT of time studying Verons books/website looking at tons of different acros over the years both when I was a retailer, and as a hobbyist. With that I've come to the conclusion that our current method for identification of acroporas is really not that polished. I think it tries to divide things into to many small groups when alot of acros w/different ids can really be slight mutations of each other. There are species ids that look VASTLY different then each other, and others that get different ids and are very much similar. The means of which things are measured can very on the same colony, even on the same branch. You pull 2 branches from a single colony and depending on where it sits in relation to the other branch there are going to be differences in growth patterns, polyp density.. etc. If it was up to me acros would be divided into groups of "general" corallite shape. Which would mean a lot less coral species but imop that wouldn't be a bad thing as I've found (and I could be wrong here) most of the corals that have very similar shapes come from similar environments, and have similar needs. So arguing over a spathulata, millipora, or a prostrata would really be a mute point as they would all be known as Acorpora MammothReefer 1a.
