Pterois is a genus of venomous marine fish, commonly known as Lionfish, native to the Indo-Pacific. The Lionfish is a predatory fish hunting small fish, but its venom is capable of being fatal to larger creatures.
The Lionfish is a popular aquarium fish around the world, although the Lionfish is better kept in tanks with lots of space and few other fish. The Lionfish can live to around 16 years in the wild and often live longer if looked after well in captivity.
There are around 8 different recognized species of Lionfish that are found in the Pacific Ocean. The Lionfish is natively found in coastal waters around rocky crevices and coral reefs where there are lots of smaller fish for the Lionfish to eat and also places for the Lionfish to hide.
The main predators of the Lionfish are large fish, eels and humans that catch the Lionfish to put into a tank. Although the Lionfish is a solitary animal and they only really come together to mate, a few Lionfish inhabit a certain area of the reef.
The Lionfish group usually contains one male and a few female Lionfish that the male mates with. The male Lionfish is highly territorial and protects the area in which by himself and his females live.

Lionfish Fun Facts for Kids
- # 1. The Lionfish catches its prey by hiding in a crevice in the rock or coral and then ambushing it as it swims past. The Lionfish corners its prey with its large fins before swallowing it whole.
- # 2. The female Lionfish releases between 2,000 and 15,000 eggs into the water which are fertilized by the male Lionfish. The Lionfish pair then quickly hide so that their eggs can float into the ocean before being spotted by predators that eat the eggs. The Lionfish eggs hatch in just 2 days and the tiny Lionfish fry remain near the surface of the water until they are bigger. When the Lionfish fry reach nearly an inch in length, they swim down into the ocean to join the reef community.
- # 3. The Lionfish is also an invasive species, originally from the Indian and Western Pacific oceans. It was brought into Florida as an aquarium fish, and after a hurricane broke some of the aquariums containing the fish, they started to appear around the lower coast of Florida. They have now spread all the way up to Long Island, New York.
- # 4. When scientists do dives to study the Lionfish, sometimes they kill one, and trace its DNA. The odd thing lately, is that all the fish trace back to an original six or seven Lionfish from the ocean in which they came.
- # 5. Lionfish has more than thirteen (up to 18) venomous spines on the back side of the body. Venom is used only for self-defense (lionfish does not hunt using these spikes).
