They move about by slowly undulating the soft rays of the dorsal and anal fins. During the day, they sometimes retreat to ledges and crevices among the rocks and corals. Although in the Atlantic, lionfish are often seen moving about during the day, both alone and in small groups.

How does a lionfish swim?
Lionfish move slowly using their soft dorsal and anal fins to propel them forward. But despite their lack of speed, these fish are skilled hunters thanks to their specialized bilateral swim bladder muscles that allow them to precisely control their buoyancy and therefore their location in the water column.
How do lionfish spread?
How did the fish get to the Atlantic? While the exact cause is unknown, it's likely that humans provided a helping hand. Experts speculate that people have been dumping unwanted lionfish from home aquariums into the Atlantic Ocean for up to 25 years.
What animal eats lionfish?
Lionfish have no natural predators in their invasive range. We're not entirely certain what eats lionfish in their native range, but it's most likely large predators like grouper, snapper, eels and sharks.
Why are lionfish spreading so fast?
What makes this rapid spread even more surprising is that it goes against the prevailing ocean currents which follow the trade winds across the Atlantic, into the Caribbean, and Northwestward toward Florida and the Gulf of Mexico.
How do lionfish adapt to their environment?
One adaptation is its red and white striped coloring across its entire body. As mentioned before, lionfish like to reside in coral reefs, so the coloration of its body helps it camouflage in its habitat. ... Another adaptation of the lionfish is the venom glands located at the base of certain fin spines.
How are lionfish being controlled?
To date, most control efforts have been diver-based and focused on areas with high diver visitation and shallow water. Lionfish removal by divers is considered a promising strategy for local control (i.e., specific reefs or reef areas).
Where do lionfish invade?
Lionfish now inhabit reefs, wrecks, and other habitat types in the warm marine waters of the greater Atlantic. Lionfish continue to expand at astonishing speeds and are harming native coral reef ecosystems in the Atlantic, Gulf of Mexico, and Caribbean.
Where has the lionfish spread?
Although there are reports of lionfish sightings from decades past, it is only recently (i.e., since 2000) that the species have considerably increased in numbers and spread through the Western North Atlantic, Caribbean Sea, and Gulf of Mexico (hereafter “the Region”).
How did lionfish spread in Florida?
Biologists believe they were probably introduced when aquarium owners emptied unwanted pet lionfish into nearby coastal waters. Lionfish were first officially reported in the western Atlantic Ocean in 1985. Since 2004, these fish have spread very rapidly throughout the Caribbean and into the Gulf of Mexico.
Is lionfish edible?
Eat Lionfish!
Once stripped of its venomous spines, cleaned, and filleted like any other fish, the lionfish becomes delectable seafood fare.
How long can a lionfish go without eating?
When food is scarce, a lionfish's metabolism can essentially crawl to a stop; Lad Akins, Director of Special Projects at REEF, said in one presentation not long ago that studies have shown that lionfish can live without food for up to 3 months and only lose 10% of their body mass.
Are sharks immune to lionfish venom?
Reef sharks are thought to be one of a few animals that can choke down a lionfish. To avoid the toxic spikes on its back and tail fin, said Antonio Busiello, they eat the fish starting at its mouth.
Why are lionfish fishing derbies held?
Lionfish derbies serve to educate participants and the public and raise awareness of the problem. Significant local, national, and international media coverage of derby events has helped facilitate education to those not geographically connected to the invaded range.
Why do they want to control the lionfish population?
Lionfish are voracious predators. If left unchecked, they decimate fish populations. Since they're native to the Pacific, lionfish are problematic for coral reefs in the Caribbean and the Gulf of Mexico. ... So they can depopulate reefs really rapidly.
