Osteichthyes is in fact the name of a group of fish: The bony fishes (ostheichthyes) are 95% of all fish and the most common among vertebrates. They are also the most diverse group among fishes. They include air-breathing lungfish and the lobed-finned coelacanths whose ancestors ventured on land and gave rise to amphibians. They are typically oviparous (egg-births). The common bony fish that are popular human food are the ones that live in the photic zone including sardines, anchovies, herrings, markerel, swordfish, and tuna. Those that live in the disphotic zone tend to have bioluminescent features.
Osty was part of the first MZ range (version 1.0) that I completed and exhibited in 2005, the only fish I've done so far, he's also been one of the most popular!
My long term plan, back then, was to do about 6 a year... which worked for about 2 years but then I got busy... lank busy. And any project not generating an imediate income had to be set aside.
But things change, after licencing some MZ to Toyota (my first post), I've begun working on MZ Version 3.0 but I'll post these old ones here and there :)
