What does a rattail fish eat?

Rattail fish are deep-sea dwellers, and their diet reflects this environment. They are carnivores and primarily feed on:

* Smaller fish: They will eat fish smaller than themselves, including lanternfish, bristlemouths, and other rattail species.

* Crustaceans: Shrimp, krill, and other small crustaceans are also a part of their diet.

* Squid: Rattail fish have been observed to feed on squid, though this might be less frequent than their other prey.

Their diet is opportunistic, meaning they will eat whatever prey is available in their deep-sea habitat. Their long, slender bodies and strong jaws are well-suited for catching and consuming these prey items.
