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

Interestingly, sea snakes have a higher venom yield than any other snake species on Earth! This makes them some of the most dangerous creatures in the ocean. However, despite their deadly venoms, they are not typically aggressive and will only attack when provoked.
Where do sea snakes live?
Sea snakes live in warm ocean waters near the coast. They are often found in sheltered bays or coral reefs.
Sea snakes are aquatic rather than spend time on land like most other snake species. They are closely related to the cobras and have adapted to life in water. They have an advantage living in water due to their small flatheads, which minimize the water resistance when sea snakes swim.
The body of sea snakes is compressed as an adaption for swimming. When you bring a sea snake to the shore, they become clumsy and slow because they like to live in water.
What do adult sea snakes eat?
Adult sea snakes eat mostly fish, but they will also eat eels, octopus, and squid.

Can you keep a sea snake as a pet?
