Some killie people, have been hurruphing that it is only classified as
endangered in Florida because it is seldom found in conventional surveys.
Tossing a piece of food on a string in front of a crab hole evidentally is
not standard procedure. I don't know how common mangrove swamps are.
Andy Borgia made some neat observations about these fish last year on this
list.
Dan Fromm, in a hobby article somewhere (probably an old JAKA), cited
someone who suggested that the Rivulus' ability to stay out of water was
enhanced by a relatively large number of blood vessels very near to the skin
which may have aided in oxygen absorption. Are there blood vessel rich
amphibians who do this vis-a-vis the water?
All the best,
Scott
