angler

---

they use a bioluminecent lure on there head or ext, enable to attract prey, the way this works is simple, the bacteria in the lure are hit by the water, and the angler shackes it up and causes a reaction, causing it to glow a bright blue

black swallower

---

they extend and basicly dislocate their jaw to fit anything down there throat, you can find images of these with full tum-tums 🙂

dragon fish

---

they are vary special fish, they have a red light that they and ONLY they can see, they use this and a lure to see and attract prey (just like my gardevoir) 😉

fangtooth

---

they have what would be technecly the largest teeth relative to body size, theyll eat anything they run into. just like me, exept i have standards

hatchet

---

they use their mirror like sides to reflect and attract other fish, they reflect the ocean by tilting there bodies, and attract by shining the very little sunlight in the deep sea

viper fish

---

Like fangtooth, they also have largest teeth compared to body size, exept these guys are not as aggresive, well, technecly theyre worse than me, but anyways, these guys are very small and silvery

Ralph's edit: I don't know how, but all of these fish look OP...
