Characin = Kay - ra - sin
Everything else ok.
Didn't know you closed to a dipthong in the intial syllable in Latin?

I shudder at the thought. What's funny is that despite how awefully wrong that sounds to my ears, it is probably right, though what is acceptable in taxinomical Latin is a far, far cry from what would be acceptable pronunciation in the Liturgical and Classical latin diction that I have studied. In addition, taxinomical Latin is comprised of essentially made up words using bits and pieces from Classical Latin, borrowed Greek, and then latinizing other words from other countries (Proper names, etc), so any thread of the original pronunciation goes completely out the window. Often with very humerous results. I think if we threw some Taxinomical Latin at our friends in ancient Rome, they would look at us like this.
In liturgical and classical Latin it would be "Kah rah seen" all pure vowels, no dipthongs, a flipped r, and the accent falling on the first syllable, and I still tend to pronounce taxinomical Latin in a similar fashion to Liturgical latin, making myself aware of some different vowel sounds. Or, even better, I just don't say it and point to the fish saying "That one please"
