* Fish: This is their main food source, and they are particularly fond of eels, gobies, and other small fish.
* Eggs: Some sea snakes, especially the yellow-bellied sea snake, will eat fish eggs.
* Other Snakes: Some sea snakes, like the olive sea snake, are known to prey on other sea snakes.
* Small Invertebrates: While not their primary food source, some sea snakes might consume small invertebrates like crustaceans and cephalopods.
Important Note: Sea snakes are highly venomous, and their venom is much more potent than that of their land-dwelling counterparts. However, they rarely attack humans unless provoked.
