Lone Sheep Scuba

We have all been there. You are hanging out at 130 feet, looking at a deep wreck or a beautiful reef wall, and a creeping “dark room” sensation settles into the back of your mind. Your thinking slows down, your breathing feels heavy, and tasks that are simple at the surface suddenly require a massive amount of deliberate mental effort.
Well, Helitrox may be the answer you are looking for! Read our (free) SubStack article to look at the what and why of Helitrox . There are recreational and technical courses depending on your goals.

Why is it called a 9-armed starfish? Two Guesses! 🤣

The Nine-armed Sea Star (Luidia senegalensis) is a fascinating, highly specialized tropical starfish found in the western Atlantic Ocean, including the Gulf of Mexico, the Caribbean Sea, and right along the coast of Florida.
Unlike your garden-variety five-armed starfish, this species stands out for both its unique anatomy and its specialized hunting behavior.

Key Characteristics & Anatomy
• Symmetry: While most sea stars exhibit five-point (pentamerous) symmetry, Luidia senegalensis almost always has exactly nine long, slim, tapering arms radiating from a small, circular central disc.
• Size & Coloration: They can grow quite large, reaching up to 12 to 16 inches (30 to 40 cm) in diameter. Their upper (aboral) surface features a beautiful, distinct patchwork of spiny plates—typically cream-colored along the outer edges of the arms with a contrasting band of slate-grey running down the middle.
• Suckerless Tube Feet: This is a major evolutionary divergence. Unlike reef-dwelling starfish that use suction-cupped tube feet to cling to rocks, the nine-armed sea star has pointed, translucent orange tube feet without suckers.
• One-Way Digestive System: The mouth sits directly at the center of the underside. They lack an a**s; any undigested food fragments are expelled right back out through the mouth.

Habitat & Behavior
The nine-armed sea star prefers soft bottoms, such as sandy, muddy, or silty substrates, ranging from the shallow intertidal zone down to depths of about 130–150 feet (40–46 meters).
• The Scurrier of the Seafloor: Because they lack suckers, they cannot climb vertical reefs well. Instead, their pointed tube feet act like a multitude of tiny stilts or paddles, allowing them to glide remarkably fast over—and rapidly burrow into—loose sand to hide from predators.
• Diet: They are efficient scavengers and carnivores, moving across the sediment to feed on organic detritus, small mollusks, crustaceans, and other small bottom-dwelling invertebrates. They swallow their prey whole, digesting it internally before casting the shells back out.

Local Spotlight
If you frequent the sandy lagoons, shallow estuaries, or nearshore waters along Florida's Atlantic coast, keep an eye out for them. They are occasionally spotted by local divers or beachcombers during exceptionally low tides, often half-buried in the sand with only the outline of their nine arms visible.
We see them frequently along the sandy areas at Blue Heron Bridge!

Today we look at 'THE PORCUPINEFISH: Master of Defense', as we break down the remarkable biology and complex life of this prickly reef dweller. From its incredible multi-stage lifecycle and specialized hard-shell diet to its iconic (and dangerous) defense mechanisms, this visual guide offers a comprehensive look at the fish you don't want to mess with.

The “Bugs” are Coming!
Recreational hunting for the Caribbean spiny lobster (Panulirus argus) in Florida—affectionately known by locals as chasing "bugs"—is practically a state holiday. It draws thousands of divers and snorkelers into the water every year.
Because of its massive popularity, the Florida Fish and Wildlife Conservation Commission (FWC) heavily regulates the harvest to ensure sustainability. Whether you are hunting from a boat in the Keys or shore-diving the patch reefs off the east coast, a successful hunt requires strict adherence to legal standards, specific gear, and underwater skill.
The Two Distinct Seasons
Florida splits its recreational lobster harvest into two separate windows:
• The 2-Day Sport Season ("Mini-Season"): Held annually on the last consecutive Wednesday and Thursday of July (July 29–30, 2026). This highly anticipated, fast-paced 48-hour window is exclusively for recreational fishers, giving them a head start before commercial traps enter the water.
• The Regular Season: An 8-month season that runs from August 6 through March 31. It offers a much more relaxed, strategic pace for recreational divers.
Rigid Rules & Daily Limits
FWC officers actively patrol both on the water and at the docks, and the rules are enforced with zero tolerance.
1. The Carapace Gauge Requirement
Every single lobster must be measured while you are still in the water before it is placed in your catch bag.
• The carapace (the hard part of the shell from between the eye sockets to the rear edge of the thoracic armor) must measure greater than 3 inches.
• If it is exactly 3 inches or smaller, it is illegal. You must carry an approved plastic or metal lobster gauge with you on every dive.
2. Daily Bag Limits
• Monroe County (The Florida Keys) & Biscayne National Park: 6 lobsters per person, per day.
• The Rest of Florida: 12 lobsters per person, per day during Mini-Season only; drops to 6 during regular season in certain areas.
• Note: Pooling catches is illegal; you cannot catch extra lobsters to fill out a buddy's limit.
3. Egg-Bearing Females ("Berried" Lobsters)
Males attach a thick s***m packet (called a tarspot) to the underside of the female's body. When she releases her eggs, she scratches the packet to fertilize them, carrying the bright orange eggs under her tail (making her a "berried" lobster).Look at the underside of the tail immediately. If you see thousands of bright orange, yellow, or brown eggs attached to the swimmerets, the lobster is "berried" and must be released unharmed immediately, regardless of its size. Stripping eggs off a female is a severe wildlife felony.
4. Keeping Them Whole
Lobsters must remain completely whole while you are on the water. Tailing a lobster at sea to save cooler space is strictly illegal; they can only be separated and cleaned once you are safely back on land.
Gear & Pro Catch Techniques
Unlike New England lobster hunting, spearing, hooking, or gaffing spiny lobsters is strictly illegal in Florida because any punctured lobster cannot be released alive if it turns out to be undersized or berried. Instead, hunters rely on finesse and varied toolsets:
• The Tickle Stick & Hand Net Combo: You gently guide a long aluminum or fiberglass rod (the "tickle stick") behind the lobster in its hole and tap its tail. Because lobsters naturally swim backward when startled, it will march right out of the crevice into the net you have pre-positioned.
• Lobster Snares: A spring-loaded loop mechanism that can be placed around the tail and tightened. It requires precision to avoid damaging the shell or crushing the internal organs.
• Gloves: Thick protective gloves are non-negotiable; the sharp spines and defensive whipping of a large lobster can easily slice open bare skin.
Safety & Dive Etiquette
The sudden influx of thousands of boaters and divers makes safety the single most critical factor of the harvest.
• Dive Flags: You must display a standard divers-down flag (with rigid stiffener) on your vessel or a float. Divers must stay within 300 feet of their flag in open water, or 100 feet in rivers, inlets, or navigation channels. Boats must maintain idle speed within these boundaries.
• Overhead & Eco-Awareness: Many lobsters hide deep within delicate coral heads or structural ledges. Hunters must maintain flawless buoyancy control to ensure they do not crush reef structures, stand on live coral, or kick up blinding clouds of silt while reaching into holes.
• No-Take Zones: Large swaths of Florida waters are completely closed to lobster harvesting. Knowing the exact GPS coordinates of your dive site's boundaries and local rules is essential before splashing.

Experience matters a great deal when choosing a scuba instructor, and even more so when looking at advanced or technical training. In this short free Substack article and infographic, we’ll explore what “experience” really means, why the dive industry often undervalues it, and how students can make better, safer choices when selecting an instructor.
