What do gray dolphins eat?

There is no such thing as a "gray dolphin". Dolphins come in many shades of gray, but there's no specific species called that.

To answer your question, dolphins (in general) are carnivores and their diet varies depending on the species and location.

Here are some common prey items for dolphins:

* Fish: This is a primary food source for many dolphin species. They eat a wide variety of fish, from small sardines to larger tuna.

* Squid: Dolphins also enjoy squid, and some species are known to specialize in hunting them.

* Shrimp and other crustaceans: Some dolphin species will eat crustaceans like shrimp and crabs.

* Other marine mammals: Larger dolphin species like the killer whale (which is actually a dolphin) can hunt other marine mammals like seals, sea lions, and even other dolphins.

If you can specify the species of dolphin you're interested in, I can give you a more detailed answer.
