Lost, Confused or Temporarily Misplaced:
Navigation for Novices
Most people learn to drive before they dive, and, fortunately, a good
deal of what is learned from navigating cars along country roads or city
streets translates to the underwater world. By taking a closer look at
the way we learn to navigate on land, we can draw some important
parallels for how we navigate underwater.

Fish Senses, Part One:
The Sense of Smell
Fish use smell for a variety of roles, from locating a mate and finding
dinner, to detecting predators, and, perhaps, even for finding their way
home. But - and there's always a "but" - fishes' sense of smell may be
too sensitive. In fact, you could say that they may not be able to rely
on smell, just when they need this sense the most.

Endangered, Threatened or Thriving?:
Exploring the Status of the Florida Manatee
Many feel that conservation efforts have re-established Florida's
manatee population so well that the manatee should no longer be
considered an endangered species. In fact, the Florida Fish and Wildlife
Conservation Commission is considering downlisting what is perhaps
Florida's most famous resident from its current status of "endangered"
to "threatened." But is such a move justified? And if the change occurs,
what will it mean to the manatee?
