What Do Sea Snakes Eat?

Sea snakes are some of the most fascinating creatures in the ocean. They come in various colors and sizes, and they all have one thing in common – they love to eat fish! Sea snakes can be found worldwide, and each type has its unique diet.

This article will explore what sea snakes eat and what kind of fish they prefer. We’ll also look at some of the most common myths about sea snake diets.

What Do Sea Snakes Eat

So, what do sea snakes eat? Well, it depends on the type of sea snake. Some species are known to eat eels, while others prefer small fish. Still, others will only eat certain types of shrimp or crabs.

It varies from species to species! However, one thing that all sea snakes have in common is that they love to eat fish. Fish make up the majority of a sea snake’s diet.

List of food Sea Snakes Eat:

  • Fish
  • Crustaceans
  • Octopus
  • Squid
  • Worms

Sea snakes are carnivores, and their diet consists mainly of fish, crustaceans, octopuses, squid, and worms. Some species also eat eels and frogs. Sea snakes typically hunt by ambush, waiting for unsuspecting prey to come close before striking.

They are not known to be aggressive towards humans, but they can bite if threatened or handled carelessly. While the venom of most sea snakes is not deadly to humans, it can cause pain, swelling, and nausea.

Sea Snakes Preferred Diet

Snakes Preferred Diet

Based on the 1983 report, the volume of specific food items consumed by sea snakes varied depending on the area they were found in.

However, their preferred diet items remained consistent and included fish, eels, and shrimp. The report says that these dietary preferences were likely because these food items were most available to the snakes.

In other words, they ate what was easiest for them to find and capture.

Now, let’s take a closer look at these three dietary staples for sea snakes.


A 2016 study published in the journal Biological Bulletin looked at the stomach contents of 84 different species of sea snakes. They found that fish made up anywhere from 50-100% of the total volume of food found in the snakes’ stomachs.


Eels were the second most common food item found in the sea snakes’ stomachs, making up 10-50% of the total volume.



Shrimp was the third most common food item found in the sea snakes’ stomachs, making up 0-10% of the total volume.

Sea snakes have sharp teeth that help them to tear apart their prey. They have a hinged jaw that allows them to open their mouths very wide, making it easier to swallow their prey. Sea snakes typically live in the ocean’s coral reefs, where they can find plenty of food to eat.
