Thanks for the kind words, much appreciated.
Growth rates seem to vary so much, based on diet locale and possibly genetics; hard to speculate but I like to think 100+ is possible. Some years ago I was horrified to come across an 18 year old Spectacled Caiman that fit quite comfortably in a 20 gallon aquarium, courtesy of its chop-meat based diet!
I believe Rhom Whittaker did a film awhile back, documenting his (unsuccessful?) search for a 20+ footer, maybe set in Australia? He also predicted that with protections in place, we might expect huge ones in time. Similar scenario now with American Alligators in the USA.
best, Frank
