Thanks Greg.
photobarry, if you look closely you will also see several more teeth migrating, but most of them in earlier stages of their journey.
XxAngelzDustxX, this photo is only zoomed about halfway, because that is where the closest focusing distance is on the nikon 4500. I estimate that the distance to the subject was about 3 cm from the lens in this shot. I don't know at what zoom position the 2500 has its closest focusing distance, but unfortunately most cameras have it in wide angle position.
cjm033, I guess you are refering to the end of an algae that is about to get eaten?
Snail Guy, Good luck and let those juices flow freely. I'm looking forward to see your teeth!
Here is another photo. This time it's my Royal Gramma Basslet making a small yawn. Photo was shot with my Casio 2800UX.
