One topic that caught my eye was a study about the changes in the population of yellow stingrays in various parts of the Caribbean.  The Florida Keys had the largest decline, while Jamaica had an increase. Why is that significant? Why should we care about yellow stingrays?
Cleaning Stations: the Ultimate Hygiene System

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.
Angels on the Reef

Angelfish 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 reefs, since that is also the place we find the highest population and variety of sponges.
Goliath Grouper... Gentle Giants of the Reef
Series: Marine Life. Price: $2.99 USD. Words: 2,700. Language: English. Published: March 11, 2017. Categories: Nonfiction » Sports & outdoor recreation » Scuba & Snorkeling, Nonfiction » Children's Books » Animals / Marine Life
Itʼs common knowledge that Goliath groupers were nearly wiped out by overfishing up through the 1980s. Even though Goliath groupers have staged a comeback - estimates are about 35 percent compared to earlier populations - the benchmark figures are inaccurate. The stock is nowhere near historical levels, based on research. Another comment I saw berated Goliath groupers for decimating other fish pop
Butterflyfish: Graceful Reef Gliders

There’s one thing I can guarantee I’ll see on every dive. Some sort of butterflyfish will be wherever I’m going. The REEF fish identification book has six species listed in the Caribbean. I have five of them in my image inventory, and most likely will never see the other one. In the Pacific there are well over 100 species.
The Great Hamlet Debate

There has been a debate on the number of hamlet species. The original classification was for one species, and color variations didn’t matter. Research is now shedding light on color differences. For example, the indigo hamlet is different in two ways. Another interesting study shows areas of concentration by color pattern, with blue hamlets being the dominant species in the Florida Keys.
File this Fish with the Shy Group

Filefish have a protruding mouth with some very sharp teeth, similar to a triggerfish. They have narrow, compressed bodies with rough spiny scales and a front dorsal fin that can be raised or lowered. When the fin is raised, it resembles a file, which some reference sources say is the inspiration for the name. Filefish are another group of highly entertaining critters on the reef.
Look for the Fish in a Box
Series: Marine Life. Price: $2.99 USD. Words: 2,570. Language: English. Published: April 29, 2017. Categories: Nonfiction » Sports & outdoor recreation » Scuba & Snorkeling, Nonfiction » Children's Books » Animals / Marine Life
When I want a chuckle, I look for a fish in a box. Not a cardboard box of fish like you get in a bait shop, but a body box that fits perfectly and is color matched to its occupant. I’m referring to a group of animals called boxfish. They look like little robots scooting around the reef in search of a new power source. The Energizer bunny with fins and armor - and in some cases, horns.
Schooling Activity is Alive and Well on the South End of Molasses
Series: Marine Life. Price: $2.99 USD. Words: 2,710. Language: English. Published: April 22, 2017. Categories: Nonfiction » Sports & outdoor recreation » Scuba & Snorkeling, Nonfiction » Children's Books » Animals / Marine Life
Many reasons are given for schooling activity. Schooling occurs in up to eighty percent of species at some point in their life. Protection from predators, breeding and searching for food are top reasons cited for schooling behavior. There is also an advantage in riding the vortices created by the swimming motion of the fishes themselves - like a race car drafting behind the car in front of him.
The Brass Section of the Reef

Trumpet fish are part of the Syngnathiformes family. Don’t fret, I can’t pronounce it either. It’s actually quite a large group. Cousins include seahorses, pipefish, sea dragons, shrimpfish, and sea moths. Bony exteriors and small tube-like mouths are characteristics of syngnathids. Like seahorses, trumpetfish males carry the eggs. The scientific name actually translates as “flute mouth”.
Invasive Orange Cup Coral Silently Grows off the Keys
Series: Marine Life. Price: $2.99 USD. Words: 2,850. Language: English. Published: May 20, 2017. Categories: Nonfiction » Sports & outdoor recreation » Scuba & Snorkeling, Nonfiction » Children's Books » Animals / Marine Life
Orange cup coral is an invasive species. So far it has specialized on artificial reefs, dock pilings and oil rigs. On vertical surfaces, water movement, distance above the sea floor and less sedimentation than horizontal surfaces favor orange cup coral growth. Since most of our local reef structure does not have significant vertical wall structure, artificial reefs will be prime targets.
The Glassy Side of the Reef

The variability of salinity levels in Florida Bay is important to the food chain. What does this have to do with glass minnows? Well, everything. He examined the relationship between mesozooplankton, salinity and bay anchovies. The ecological implications center on the the relationship between salinity, mesozooplankton and bay anchovies. Future changes in salinity could have significant effects.
Hogfish Heaven?

Hogfish got their name because they root around the sea floor, like a hog roots around the barnyard. I have been following the size limit discussions for the last several years, and to me the essential point is this: if we don’t increase the size limit and let them grow another year or two, the chances of maintaining a sustainable fishery may be a huge issue in the future.
Let's Wake Up an Eel and Go Hunting
Series: Marine Life. Price: $2.99 USD. Words: 2,780. Language: English. Published: June 25, 2017. Categories: Nonfiction » Sports & outdoor recreation » Scuba & Snorkeling, Nonfiction » Science and Nature » Life Sciences / Marine Biology
While the majority of observations during the day are while eels are resting or on a cleaning station, a few times I have seen an eel coupled with a grouper. The first time I saw it was on the Winch Hole. A graysby came to a stop on a pile of rubble, and a goldentail came out from its lair. At first they just sort of looked at each other, then came cheek to cheek, touched, and took off together.
A Whale of a Good Time (Maybe)

As I stood on the boat with my morning coffee and watched the people pile in the boats and head out to the whale sharks, my immediate reaction was “we are in a whale shark theme park”. I believe it’s become more about the peso than the whale shark. I can’t blame them for developing the tourism business, but is there a balance that can be reached? This has spawned a great deal of controversy.
All Puffed Up

Puffers are a group of fish I like to shoot, especially the big ones. They have a shy, jovial personality. At least they always look like they are smiling. Puffers are related to boxfish, and are also toxic, but in a different way. I found references to two toxins, tetrodotoxin (TTX) and saxitoxin (STX), which are nerve agents. They are chemically distinct, but act on the nervous system similarly.
This Goat Is a Hero
Series: Marine Life. Price: $2.99 USD. Words: 2,690. Language: English. Published: July 23, 2017. Categories: Nonfiction » Sports & outdoor recreation » Scuba & Snorkeling, Nonfiction » Science and Nature » Life Sciences / Marine Biology
Classified as a “nuclear” species, goatfish truly play a leadership role. Other species are attracted to the substratum-disturbing foraging. And when several goatfish are involved in the fray, the groupies increase in number and diversity. Goatfish groups attract up to six follower species. While many of the follower species eat the same food, the goatfish don’t seem to mind.
Wrasses: the Smartest Fish?

Wrasses are a large and diverse family, and seem to be everywhere. They are quick and colorful. Perhaps some of the most vibrant colors on our reefs belong to the family of wrasses. Worldwide there are over five hundred species of wrasse. Here we have about twenty. Most species are carnivorous, feeding on small crustaceans.
