Meet the yellow-lipped sea krait – one of the deadliest snakes in the world. These snakes are venomous and do not bike unless provoked. Other names for these snakes are colubrine sea krait or banded sea krait. These amazingly venomous snakes have yellow snouts and black stripes, making them beautiful and distinct from other species.
Yellow-lipped Sea kraits have a distinct paddle-like tail used for swimming in the sea. Most of the time, they reside in the water but digest, rest, and reproduce on the land. It’s one of their specialties to use neurotoxic venom to prey on small fishes and eels. What’s more? They are dangerous and can attack if they feel threatened.
This article will be interesting because we will discuss the yellow-lipped sea kraits’ sea life. Everything related to it will be discussed here. This wild snake is poisonous, and we will try to answer all the queries in your mind. So, let’s dive deep into the sea of insights about it.

About Yellow-Lipped Sea Krait Habits and Lifestyle
The habits and lifestyle of these sea kraits are worth considering mentioning here. Yellow-lipped Sea kraits love to live in the water. They also live near coastal areas. Adults amongst yellow-lipped sea kraits spend half their time in water and half on land. In simple words, they are semiaquatic. This is how they are adapted to the environment.
Males hunt in shallower water, while females hunt in deeper water. It’s quite interesting that males are smaller in size. It’s also the reason behind their fast crawling and swimming speed. Their body adaptations help them to swim easily and quickly.
They can still move, although at a slower pace when on land. Sometimes traveling great distances from shore in search of prey, Yellow-lipped Sea kraits eventually make their way back to the islands that are their permanent residences.
They typically forage singly but may form big groups with giant trevally and goatfish. Trevally and goatfish work together with sea kraits to chase prey out of tight spaces, and the kraits then feast on the fleeing prey.
If a sea krait sticks its head into a crack, it may not be able to see any potential threats that may be approaching. The snakes’ tails look and move similarly to their heads. They can trick predators like larger fish, sharks, and birds into thinking the tail is the head.
Diet and Nutrition
According to Animalia’s research,
“Yellow-lipped Sea kraits feed on eels and small fishes. They are carnivores or piscivores.
That’s why they love to eat meat. They are meat eaters.” (Source)
Once their prey is in their grasp, they use their potent venom to render it helpless before swallowing it whole. In addition, the sex differences between these snakes manifest themselves in how they prey.
The smaller eels that men need to eat are only found in shallow water, so they focus their hunting efforts there, while the larger eels that females like can be found in deeper water. Because of this, males engage in more eel hunting than females, who typically only catch one eel every trip.
“The families of eels that they love to eat include Congridae, Muraenidae, and Ophichthidae. The families of small fish that they feed on include Pomacentridae and Synodontidae.” ~ (Source)
Reproductive system (Mating details)
Their mating or reproductive system is absolutely interesting. Reptiles Cove has explained it in detail. Let’s quote it now here:
“Sexual maturity occurs between 18 and 24 months of age in men and 24 to 36 months of age in females. It’s conceivable that these snakes travel to the ground to reproduce. Banded sea kraits, unlike most other species of sea snake, typically lay their eggs on
land, most often on rocks. “
The author further added,
“Females were reported to be capable of laying 4 to 20 eggs. Only the female sea snakes lay eggs. To mate and have babies, they come back to land. The months of September through December are prime mating time, although this isn’t always the case, especially in more tropical regions.” (Source)
The banded sea krait swims with the help of its tail, which acts like a paddle and glides back and forth to propel it through the water. Sea kraits, while ashore, modify their slithering swimming motion into a more conventional type of locomotion on hard ground.
Interestingly, it adopts a “side-winding” action like many desert species of terrestrial snakes when it encounters loose materials like dry sand. Although they are most active at night or twilight, they are not typically considered to be strictly nocturnal.
During the day, they tend to assemble in small groups, hiding in nooks and crannies, among tree roots and holes, or beneath discarded items on the beach. To maintain a comfortable body temperature, they will frequently switch between periods of shade and sun.
Interaction With Humans
Even when provoked, banded sea kraits show little interest in biting humans. Some Laticauda Colubrina bites have been recorded, and there is evidence that the species occasionally invade human dwellings and vessels.
Human fatalities from assaults by this species are unheard of, though. These snakes are less interested in humans, and they love to live a happy sea life. They usually indulge in their own life.
Where Do Yellow-Lipped Sea Kraits Live?
Most of the population of yellow-lipped sea kraits live near turtle island, Fiji. The Pacific Ocean is their home. They are quite common in this ocean.
What’s more? Laticauda Colubrina lives in islands and reefs. If we talk about all species of sea kraits, four of the species live in water and mostly in the Pacific Ocean.
What Does A Yellow-Lipped Sea Krait Eat?
Eels are their favorite foods. As we have already stated, they live in water, and it is obvious they are also fish lovers. They eat small species of fish.

● Abdominal pain
● Cramps in the abdomen
● Difficulty speaking or swallowing
● Altered mental status

According to research given in NCBI about symptoms of sea snakes:
“Vomiting and nausea are the most common symptoms of envenomation of all sea kraits. They can then further lead you towards fatal conditions like coma, breathing problem, heart failure, kidney failure, or even death.” (Source)
Yellow-Bellied Sea Snake Venom Effects
The effects of the venom of a yellow-lipped sea krait are hazardous. Everyone discusses that it’s one of the deadly creatures, but nobody discusses how dangerous it is. That’s why we have decided to answer it in gory detail.
What next, if the yellow-bellied sea snake bites you and its venom enter your bloodstream? The initial signs are similar to the flu, including feeling sick, having a headache, and sweating excessively.
As soon as the neurotoxic venom from the snake enters your body, it begins shutting down your neurological system. The Pelamis poisons are the most vital components of the stew since they are proteins.
Pelamis toxins completely shut down the neurological system by attaching to neurons and blocking their electric signals, preventing movement or feeling from reaching the muscles. If you stop those neurons from firing, you’ll go paralyzed.
Venom can cause cardiac arrest or asphyxia if it reaches the diaphragm or heart. If you make it far enough, your kidneys will fail from overuse due to the breakdown of skeletal muscle and the subsequent release of waste products into the bloodstream.
Is There an Antivenom for Yellow-Lipped Sea Krait?

“Antivenin polyvalent sea snake is the drug for the treatment of sea snake bites. This antivenom is prepared from hyperimmune horse globulin for the treatment of N scutatus and Enhydrina schistosa.” (Source)
Research Gate’s research has also suggested the following anti-venom for the treatment of venom of yellow-lipped sea kraits:
“The Antivenin Enhydrina schistose is the only commercially available antivenom for sea snake bites. It is still challenging to obtain Antivenin Enhydrina schistose in some places, although it has been shown to have a good neutralizing effect on the venoms of some species of terrestrial snakes and sea snakes.” (Source)
