Some fish just have an irresistible appeal to me. While I like the thrill of encountering an animal larger than me, the tiny critters are often just as interesting to observe. All those little folks that inhabit small portions of the reef have an important role in everyday reef ecology.

This year is beginning on an interesting note. There is a lot going on that is relevant to the diving community and may influence how we interact with the reef. Over the course of the year, we will examine these topics as they unfold.

When I lived in Virginia Beach I was pals with a couple spearfishermen. About 12 miles off the coast lies Chesapeake Light Tower, where we used go for a festive day on the water.

While I was researching goatfish for the last column, I realized there is another group I have not paid enough attention to in my reef travels. Wrasses.

DIVE TIME

More often than not, I don’t pay much attention to individual goatfish. Seeing large schools of yellow goatfish at a place like Snapper Ledge always makes for a great dive.

Photographing a spotted goatfish at night with its bright colors on display is also a favorite goatfish observation.

But a goatfish here and there with its barbels flailing away creating a cloud of sand and debris is not my preferred set up for a clear image.

Pillar coral, found at reefs throughout the Keys, is among the coral species that would be added to the Endangered Species list.

Seven corals found in Florida Keys waters could be added to the list of oceanic species federally protected under the Endangered Species Act.

The decision announced Friday by the National Oceanic and Atmospheric Administration will bring federal officials to the Keys for public comment hearings Jan. 15 and 16.

"We've watched the changes on our reef over the years and the loss of coral has been significant," said Judy Halas of Key Largo, who has been diving Keys reefs for more than four decades as an author and activist.

Members of the National Association of Black Scuba Divers use tape measures to chart a Key Largo wreck formally identified this week as the cargo steamship 'Hannah M. Bell.' The ship sank in April 1911 while carrying coal to Mexico.

Sunken remains of a steamship lying on the Key Largo reef for more than a century now have an official name -- the Hannah M. Bell.

Archaeologists with the federal Office of National Marine Sanctuaries confirmed this week that everything known about the shipwreck matches up with recorded descriptions of the Hannah M. Bell, which sunk on April 4, 1911.

Back in the 1980s, when I became a certified diver, the handling of animals was viewed a bit differently than it seems to be nowadays. On those early trips I remember the Cheez Whiz cans, taunting an octopus or a turtle, and some other stuff I’d rather not mention in the era of modern etiquette. Among these antics, making a puffer fish bloat was always an entertaining event.

Anticipation. Like the ketchup falling from the bottle in that old TV commercial, we are anticipating a visit with whale sharks near Oslob, in the Southern Visayas, Philippines. We are on the Philippine Siren running ahead of the wind to a safe harbor.

This is the 'Duane,' sister wreck of the 'Bibb.' Both were sunk 25 years ago this November one day apart off the Upper Keys and now teem with marine life.

For a quarter of a century, advanced and experienced divers have enjoyed diving twin Treasury Class 327-foot U.S. Coast Guard cutters off Key Largo. All the vessels in this class, referred to as the 327s, were named after former secretaries of the United States Treasury Department.
