  • Diving the Spiegel Grove... Wreck or Reef?

    Wreck, #1

    by Tim Grollimund ...
    Series Book 1 - Wreck
    The Spiegel Grove has a wealth of opportunity for great diving. Not only because it is an icon of Key Largo, it's just plain fun, sprinkled with a bit of a challenge at times. I have been on the Spiegel in a wide variety of conditions... less than 30 feet of visibility, with loads of current, to clear 80-plus visibility days when you can drop down, instead of pulling yourself down, to the wreck. ...

  • Photo Tour of the Philippines

    by Tim Grollimund ...
    At Atlantis Dumaguete, I saw a whole host of things I'd never had the opportunity to photograph before. The mandarin fish mating dance, a pregnant mantis shrimp, a blue ribbon eel and sea snakes are the most memorable to me. Lots of pipefish, sea horses and nudibranchs live in the seagrass, which made the hang time quite enjoyable. We would spend the last 10 to 15 minutes on the grass beds ... Read more

  • Snook Recover After 2010 Cold Snap

    by Tim Grollimund ...
    "An interesting aspect of the snook population is documented in the telemetry study from the FWC Fish and Wildlife Research Institute. They acoustically tagged 30 snook in the 9-square mile Banana River No-Take Reserve near Kennedy Space Center. This is one of the oldest no-take reserves in the country. They looked at the movement of snook within protected waters and beyond.They examined the no ... Read more

  • The Eagle Has Landed... or Not

    by Tim Grollimund ...
    One of the most popular charismatic mega fauna in our waters is the spotted eagle ray. Kim Bassos-Hull, from Mote Marine Laboratory, has been studying spotted eagle rays (SERs) since 2009. Her work has centered primarily along the coast from St. Petersburg to Sanibel Island. She is collecting data in the Florida Keys to enhance and expand her studies, but as of today, no critical habitats for ... Read more

  • Wherever You Go, There's No Place Like Home

    by Tim Grollimund ...
    Don't get me wrong - there are many, many places I'd love to see. But coming home to the Florida Keys is an exotic destination in itself. Just look at our statistics. Millions of visitors a year come here to see the third largest barrier reef system in the world. Not too shabby. So when I got home from the Philippines, it was like coming home to a vacation that was interrupted by another vacation. ... Read more

  • Spadefish Have to Dig Their Way Out of a Hole

    by Tim Grollimund ...
    "Spadefish are the only species of its family that reside in the Western Atlantic. In the Pacific there are at least six species of spadefish, where they are also commonly known as batfish. While they are common in the Keys, in other parts of the Caribbean they are not as prevalent. I've seen schools numbering in the hundreds from the south end of Molasses all the way up to Carysfort. One of the ... Read more

  • Damselfish May Be More Aggressive Than You Think

    by Tim Grollimund ...
    "How aggressive are damselfish, pound for pound? As it turns out, divers invading their space is not the only thing damselfish exhibit aggression over. I don't blame them for defending their territory when I'm trying to get a shot. That's common, and can be comical. The species in our waters vary in size, color and behavior. There is an excellent, detailed chapter on all the damselfish species in ... Read more

  • Small Wonders on Reefs and Wrecks

    by Tim Grollimund ...
    Today's thoughts are primarily for all the folks I see with compact camera systems on dive boats. If you are new to underwater photography, I applaud your entry into the submerged imaging realm. It's your efforts shooting photos that help spread the wonder, beauty and splendor of the ocean treasures found on the reefs and wrecks. Sending your photos to folks or posting on social networks are great ... Read more

  • Oh! Those Sweet Red Lips!

    by Tim Grollimund ...
    I want to spend more time watching redlip blennies. They mate beginning at first light in two week cycles that start ten days before the full moon. The mating sessions last about three hours each morning, and males generally have female visitors every day. Sometimes the same females come back, but usually there are different mixes among males and females. Females spawn every other day with up to ... Read more

  • The Less Traveled Reef: Going Deep Reveals Abundant and Unusual Sealife

    by Tim Grollimund ...
    There are a few places in the outer edges of the Florida Keys reef tract that are a whole different world. Deep French, Deep Elbow and Deep Molasses are quite different than the shallower namesakes. The contours begin around 50 feet, and usually bottom out in the 80 to 90 foot range. Nitrox is the preferred gas on these dives, with a mix of 32 to 36 percent preferred. Once you are down the line ... Read more

  • Cleaning Stations: the Ultimate Hygiene System

    Marine Life, #2

    by Tim Grollimund ...
    Series Book 2 - Marine Life
    Cleaning stations are an essential element in reef ecology. All three parties - cleaners, clients and parasites - are part of a big matrix that runs the gamut from mutually beneficial to intrusive or harmful. When I first began my research, I thought this would be a no-brainer. A fish or turtle pulls into the station, gets its windshield cleaned and oil checked by a wrasse, a goby or a shrimp, and ...

  • Angels on the Reef

    Marine Life, #3

    by Tim Grollimund ...
    Series Book 3 - Marine Life
    I always try to photograph angelfish. My image inventory probably has more angelfish photos than any other group. They are the most colorful and beautiful animals on the reef, in my opinion. Some are very shy, like Rock Beauties. Others have varying degrees of aloofness, depending on the conditions and circumstances. The best spots for angels I've seen are the deeper parts of Molasses and French ... Read more
