Tiger Shark

Galeocerdo cuvier

Fun facts for your next surface interval

Growing out of its stripes: its tiger stripes are often clearer on younger sharks than on very large adults.
Built for a tough meal: tiger sharks can eat hard-shelled turtles, helped by their strongly serrated cutting teeth.
A misleading family name: despite their similar common names, tiger sharks and sand tigers belong to different families.

Florida and local context

Florida regional occurrence; no site-level or abundance claim: FWC documents the species in Florida coastal and offshore waters. This regional evidence does not establish abundance or residency at a Palm Beach dive site.

Documented regional presence is not a guarantee of an encounter or a measure of how common this animal is at your dive site.

How to recognize this animal

A broad, blunt head, thick forebody and dark vertical flank bars are the classic tiger-shark combination. The tail’s upper lobe is long, while the body narrows markedly behind the first dorsal fin. Young sharks often carry more spotlike markings; the bars become less obvious in large adults. A faint pattern does not rule the species out.

Size and life stages

FWC reports that tiger sharks can reach roughly 15–18 feet (4.6–5.5 meters), making them much larger than most coastal sharks in this guide. Size estimates made underwater are imprecise, particularly without a reference object. Newborns are about 27–34 inches (69–86 centimeters), already substantial fish but very different in proportions and pattern from a large adult.

Habitat and where to look

Tiger sharks use a wide variety of coastal and offshore settings, including bays, reefs and deeper shelf waters. They are not restricted to coral habitat or clear blue water. A large individual can travel between feeding areas, so the place where it is photographed may be one stop in a much broader pattern of movement.

Range and local context

FWC records the species around Florida, within a much wider tropical and warm-temperate distribution. Florida occurrence does not mean routine visibility at any particular Palm Beach reef. Regional and seasonal movements matter, and a single sighting cannot establish a resident population. Treat this as a broader Florida identification entry, with locality details attached to each actual observation.

What is on the menu?

Tiger sharks eat an unusually broad selection of prey, including fishes, rays, other sharks, turtles, crustaceans and carrion. Their heavily serrated teeth are suited to cutting tough material. Reports of swallowed human-made objects are real but should not turn pollution into a feeding joke: debris is a hazard, not an appropriate addition to a shark’s diet.

Daily habits and behavior

These sharks are wide-ranging predators rather than animals tied permanently to one small reef shelter. Their slow-looking cruising can conceal considerable strength and mobility. Observe the direction of travel and keep a clear route ahead of the animal. A shark investigating an object is not an invitation to offer food, touch it or test its reaction.

Mating and the next generation

Tiger sharks bear live young without the placental arrangement familiar in many other coastal sharks. Gestation lasts about a year, and FWC reports litters of approximately 10–70 pups. Juvenile markings are often stronger than adult ones. Males have pelvic claspers, but a casual side photograph usually cannot establish sex reliably; body stripes do not provide that distinction.

Look-alikes and identification traps

A sand tiger is a different kind of shark: it has two similarly sized rearward dorsal fins, a pointed snout and protruding narrow teeth. The tiger shark’s broad head, strongly unequal dorsals and vertical bars distinguish it. Large unmarked adults also require attention to head and tail shape. The shared word ‘tiger’ does not imply a close family relationship.

Observe without disturbing

Remain with your buddy or group and let the shark pass without surrounding it. Do not carry bait or try to create a closer photograph by changing its behavior. A useful identification image includes the head, flank pattern and tail in one frame. Leave uncertain size estimates approximate, and record the location without encouraging people to chase the animal.

Harvest, protection and eating safety

Protected: no state-water harvest

Florida state waters: protected year-round, with no ordinary recreational harvest season. Release accidental catches without delay with gills submerged. Federal species and HMS-vessel rules must also be checked. Shark mercury advice does not create a harvest exception.

This color is a qualified summary, not permission to collect or a guarantee that a particular catch is safe to eat. Read the current rules and health guidance below.

Protected in Florida state waters: no recreational harvest

Can it be hunted or harvested?

Do not harvest, possess or land this species from Florida state waters. No size, bag allowance or harvest permit creates an exception for ordinary recreational fishing. Release an accidental catch without delay, keeping the shark in the water with its gills submerged and following FWC handling requirements.

Florida seasons and areas

Florida state-water protection applies year-round. This is not a claim that every federal shark rule is identical: federal species restrictions and HMS vessel-permit conditions must also be followed for the trip. Marine parks, sanctuaries and local closures may be stricter.

Can it be speared?

No. Florida prohibits spearing sharks, including this protected species. Never use a spear, powerhead or bangstick to collect it.

Is it safe to eat?

Not a food-harvest recommendation: retention is prohibited in Florida state waters. FDA lists shark among the highest-mercury Choices to Avoid for people who are pregnant, might become pregnant or are breastfeeding, and children ages 1–11. Other consumers should consult current Florida DOH species and catch-area advisories; no individual shark is certified safe by this profile. The June 2021 guide currently linked by Florida DOH says not to eat coastal-water sharks 43 inches or longer, for any listed population. Below 43 inches, it advises women of childbearing age and young children not to eat them, and other consumers to limit them to one meal per month. This is an older currently linked guide, not a new 2026 table; recheck the current advisory before eating. The guide defines a meal as six ounces of cooked fish; consult current advice for age-appropriate portions and count other fish eaten as well.

Before you act: This recreational overview is not permission to collect or spear at your dive site. Confirm the species, date, management area, state or federal waters, gear, licenses and current local closures. Identification artwork cannot establish an identification or guarantee seafood safety.
