I am sorry Mark, but you do not relax your opinions of people you do not care for. This is only one more of your side taking, at all costs.
His book is weak, it was weak at the time it was written. It does not matter if most other books were also weak. The time it was written does not account for mislabeling photos, or simple bad information. For instance, he said ackies hatched at 1 1/2 inches in lenght. Considering, ackies were hatched both in the states and in Europe(and published) since 1984, he simply made that up or was in total error.
He also showed an extreme lack of husbandry skills in his captive recomendations. Such as, do not use dirt for substrate, the reason is, all the monitors will do is dig and dig and dig, and make a mess.
Consider, these two small examples are only two of many.
Even such non-sense as the title, the giant lizard book, then includes some monitors, and other small lizards, even the title was in error and not accurate.
Consider, I have met Robert on several occasions, and he is a dear man, very very nice. But after a short conversation, I could tell he was not very pragmatic and did not have the mental abilities to actually understand the subject matter.
Another for instance, Once he called me and asked for any deceased specimens. There is indeed nothing wrong with that. I asked, what will they be used for? he explained they would be used for taxonomic studies. I then responded with, but these are only captive monitors that may or may not, have accurate locality information. He said he did not care. So they went to that nice lady from Mich. to use in dna comparisons. Sir, you cannot use imported animals of unknown locality for taxo studies.
So in the end, Robert Sprackland, is a very nice person, I enjoyed our conversations, but his book is and was, very weak. Also the difinition of a good book is how it stands the test of time. Sir please consider, thats also the true test of good information on husbandry. I will say, hes also a very brave person, as he had the guts to actually talk to me, face to face, unlike you. Thanks FR
