What are 5 adaptations that angler fish have to survive?

Here are 5 adaptations that anglerfish have developed to survive in the deep, dark ocean:

1. Bioluminescence: Anglerfish have a specialized lure, a fleshy growth on their head, that contains bioluminescent bacteria. These bacteria produce light, attracting prey in the darkness of the deep ocean.

2. Huge Mouths and Sharp Teeth: Anglerfish possess massive mouths that can open extremely wide, allowing them to swallow prey much larger than themselves. Their teeth are sharp, pointed, and often recurved, ensuring their catch doesn't escape.

3. Expandable Stomachs: To accommodate the large prey they swallow, anglerfish have evolved stomachs that can expand significantly. This allows them to feast on whatever they can catch and go long periods without needing to eat again.

4. Camouflage: Many anglerfish species are dark-colored, blending in with the deep-sea environment. This helps them ambush prey and avoid predators. Some species also have specialized skin textures or patterns that aid in camouflage.

5. Sexual Dimorphism: In some anglerfish species, the males are significantly smaller than the females and rely on a parasitic lifestyle. The male attaches himself to the female, fusing with her circulatory system to obtain nutrients and reproduce. This ensures that the male can focus solely on reproduction, while the larger female can hunt and survive in the harsh environment.
