The thresher shark, Alopias vulpinus , is a relatively common shark and frequents the tropical and warm temperate seas around the world such as the Florida coast.
Order –Lamniformes
Family - Alopiidae
Genus - Alopias
Species -vulpinus
This shark is dark metallic blue in color and can even appear to be black with a white underbelly.
The long upper lobe of the caudal fin makes this shark one of the most easily identified as this lobe can be anywhere between half and as long as the body.
Growth
The average size of an adult male is around 10-11ft. The females however can grow much larger and vary between 8-14ft. With an average weight of 400-500lbs at adulthood.
Habitat
This shark is a pelagic species inhabiting both coastal and oceanic waters.
When scuba diving around Florida, you may find young thresher sharks near the coast but this shark is normally found far from the shore.
You are most likely to observe this shark near to the surface although it does like deep waters.
Behavior
A fast moving shark which adds to the difficulty of taking one of those underwater photos you were trying to capture!
This is not an aggressive shark and should pose no threat to your scuba diving exploration. It is fascinating to watch this shark move rapidly through and out of the water as it attacks schools of fish near the surface spinning several times before it re-enters the waters.
Eating Habits
One of the fascinating tactics of this shark is how they encircle schools of fish and then stun the prey with their tails. They will carry out this tactic in groups or pairs and it is very effective.
Their main source of food is small schooling fish such as herring, mackerel and sardines.

Terence’s Tip
This shark is none aggressive towards scuba divers and will swim away when approached.
There have been reported cases of them attacking boats but these sharks should be considered harmless.
As I keep emphasizing the majority of Florida sharks are no threat but demand respect.
