What are ten facts about angler fish?

1. Anglerfish inhabit the deep sea, found at depths of up to 3,000 meters.

2. The most distinctive feature of anglerfish is their modified dorsal fin ray, which has a bioluminescent lure at the end. They use this lure to attract prey, such as small fish and crustaceans.

3. Anglerfish are ambush predators. They lie in wait, using their bioluminescent lure to attract prey. When a potential meal comes close, the anglerfish quickly strikes, using its large mouth and sharp teeth.

4. Anglerfish have a wide variety of physical appearances, with some species growing to impressive sizes. The largest species, the giant anglerfish, can reach lengths of over 10 feet (3 meters).

5. Female anglerfish are typically much larger than males, and they have a modified stomach that the male permanently attaches to. This allows the male to remain close to the female and ensures a steady supply of food.

6. Female anglerfish can lay millions of eggs at a time, which are then released into the water column. The eggs are fertilized externally by the males.

7. Anglerfish larvae undergo a series of transformations as they grow and mature. They start as planktonic larvae, but eventually settle on the seafloor and develop into juvenile and adult anglerfish.

8. Anglerfish are found in all oceans of the world, including the Arctic Ocean.

9. Some species of anglerfish have venomous spines on their fins, which they can use to defend themselves against predators.

10. Anglerfish are considered a delicacy in some parts of the world and have been featured in various cuisines.
