Dear Fellow Diver:
West Indian manatees surrounded me. They were waiting
  for me as I stepped down the pontoon boat's sturdy
  ladder to slip quietly into the water. I could have even
  done a belly flop and not scared them away. One, the size
  of a large couch, nudged me from the left, another lifted
  me from below, and a third swished his whiskers along the
  right side of my face. Behind them, others appeared to be
  waiting their turn to get close. What attracted them to
  me, a human snorkeler? Obviously, they were curious as to
  what I was doing in their space.
 A bulbous male, his face covered with warts (a condition
  known as cold stress syndrome), nudged me. I gently
  petted him. This is the only place where interaction
  with manatees is permissible. The dive operator, Snorkel
  with Manatees, was emphatic about the rules: no chasing;
  no diving below the surface to reach them; "do not disturb"
  while they are sleeping; no riding; and certainly
  no touching below their bellies "where their girl and boy
  parts are," especially the males, who might get aroused.

  parts are," especially the males, who might get aroused.
The manatees have small eyes, relative to their walrus-
  size physiques (they're as long as 13 feet and weigh
  as much as 3,500
  pounds) and puckered
  cupid-like lips, and
  they literally beg to
  be cuddled. Some will
  roll over hoping for
  a scratch. It's an
  incredible experience
  to be body-to-body
  with these amazing
  endangered mammals.
The 54-degree
  water temperature in
  the Gulf of Mexico
  during January had sent the manatees scurrying into the 72-degree
  freshwater springs near the two towns of
  Homosassa and Crystal River in Florida's Citrus
  County. Aquifers feed into the two nearby rivers,
  maintaining a constant year-round temperature.
  The abundance of manatees, which stirred
  the water, reduced visibility to 15 feet or less.
  But when a manatee is next to you, the only thing
  you don't see is other divers.
 However, by going in January, I paid a price.
  Weather delays (would you believe 12 hours?) in
  Atlanta and a late-night flight diversion from
  Tampa to Orlando were followed by a red-eye drive
  in pouring rain on the deserted, flooded Florida
  Turnpike. I arrived at the Hampton Inn in Crystal
  River at 4:30 a.m. -- and without my luggage,
  which had disappeared somewhere along the way in
  the bowels of Delta's checked-baggage transport
  system. It was 41 degrees outside, and I was scheduled to snorkel with manatees
  at 8 a.m. without my rashguard, 5-mil wetsuit, hood, socks and booties.
  Thankfully, I was able to rent a 3-mil wetsuit from Snorkel with Manatees and a
  prescription mask from another shop, American Pro Diving Center.

On the other hand, cold weather and water discourages casual snorkelers.
  More is not merrier, especially when operators welcome anyone over the age of
  three who will pay their price. When the Gulf is cold, sightings in these rivers
  and springs are pretty much guaranteed. In warmer weather, manatee sightings can
  be few and far between, and sometimes none at all. But with tens of thousands of
  tourists coming each year to Crystal River to snorkel with the manatees, I wanted
  an exclusive trip. After my third inquiry to the major operators, the disinterested
  reply sounded the same: "We leave at these times, it costs this much,
  and we take as many as 56 snorkelers." No thanks. I delved deeper into Google
  and found Snorkel with Manatees, which advertised a "maximum six-to-a-pontoon
  boat." I called owner Gene Parker, who recommended the Homosassa River, 17 miles
  to the south, which is only open for manatee snorkels from November to March.
  I booked two days, both the three-hour morning trips and the afternoon ones as
  well. When I shared my upcoming adventure with some of my longtime dive buddies
  at home, I got three "We're there" responses and one "maybe." So I called Gene
  again to ask if we could charter the boat for two days. No problem. It would be
  $400 for six hours daily, and at "whatever time you want it." I jumped at it,
  without realizing the probability of hypothermia when spending six hours in the
  cold water.
 Fortunately, Homosassa had real action among the hundreds of manatees. From
  our pontoon boat, I observed a group mating. "Watch out for the sex orgy over
  there," Captain Laura warned my group. During their sexual state of arousal,
  they can unintentionally whack a snorkeler.
  I observed a mother nursing her
  pup, a mottled baby that was chewing the
  rope attached to our ladder. Mom, guarding
  her infant, waited patiently. Like all
  wildlife, manatees need to be respected --
  don't get between a mother and her calf.
  Manatees are known to "blow snot" from
  their nostrils when surfacing. That can be
  nasty if you end up as a target.

Gene and his two captains, Erica and
  Laura, are fifth- and sixth-generation
  descendents in the area. Now in her midtwenties,
  enthusiastic Laura Wilds is recorded as the youngest, at age 16, to earn her Florida captain license (that
  record will hold because the state raised its minimum age requirement to 18).
  During our 25-minute motor from the dock at Plantation Resort to Homosassa
  Springs, Laura shared more about these fascinating mammals. Those covered with
  green algae had just arrived in the river from the Gulf. While manatees mate
  year round, females give birth every four to five years after a 14-month gestation
  period. Manatees surface to breathe every three to five minutes, perhaps 15
  minutes when they are sleeping. Mainly grass feeders, they'll eat water hyacinths
  when they are available, plus small fish and shrimp.
Lacking predators, they have no fear of humans, but few, if any, have
  unscathed bodies. Thanks to boat engine propellers, their backs are a road map
  of scars. I saw one with an unhealed chunk of missing flesh. Another killer
  is seaweed. Approximately 300 around Tampa Bay died last fall because they had
  filled their bellies with the Gracilaria seaweed when sea grass, their food of
  choice, was killed by multiple large algae blooms. According to the Tampa Bay
  News, an aggressive red tide wiped out 47,000 acres of sea grass beds, which,
  according to one scientist, compared to losing an entire rainforest.
I stayed at Crystal River's new Hampton Inn on Highway 19, the only place
  that responded to my request for a quiet room. While the view was lacking, the
  room was very nice, with a desk, two queen beds, a large bathroom, refrigerator
  and microwave. The property has Wi-Fi, a pool, gym and a complimentary breakfast.
  While I quickly tired of paper plates and spongy eggs, waffle lovers would
  be in heaven. The wonderful staff was on a daily lookout for my luggage, which
  took four days to arrive, even after I pressed Delta hard by phone (I was put on
  hold for as long as two hours). In fact, I received a call from Disney World in
  Orlando to inform me they had one of my two bags. Go figure.
 My buddies chose to stay at the
Riverside Resort, basically a two-story
motel, in Homosassa, which was certainly
convenient because our boat
docked there. Another option is the
more upscale Plantation Resort along the
Crystal River. It offers a spa, swimming
pool, two restaurants, kayak and
boat rentals, tennis and cave diving.
It operates its own dive shop. More
expensive than most large-scale operators
at $55 per dive, it is the only
shop to offer 5-mil wetsuits. It is also
conveniently located five minutes from
the manatees at Crystal River's King
Springs. Three-hour tours are offered
between 7:30 and 11 a.m. I talked to a
mother and daughter who raved about their 12-person tour, "except for the twoyear-
old and her angry mother who kept kicking me in the face."

For many people, one day of snorkeling might be enough. For me, two was perfect,
  topped off by the incredible birdlife along the way: frigates, herons, cormorants,
  white pelicans, blue heron, wood storks, egrets, anhingas, fish crows
  that "kee" rather than caw, eagles and osprey. Great fishermen, it's not uncommon
  to see an osprey flying low with a fish in its talons. That's so that the bald
  eagle, a less-savvy angler, doesn't try to steal the prey.
Despite my Delta flight and baggage delays, I would rank this experience
  second to snorkeling with the whale sharks and giant mantas at Holbox, Mexico,
  which I wrote about for Undercurrent in 2004. As Captain Laura so aptly put it,
  "Crystal River is like Disneyland in the water."
