Altonatator is a very social animal. They live in small groups with 4 to 9 specimens and often hunt together. The hatchlings learn from the adults and don't leave the herd until a age of 6 years.
Different to all seasnakes, Altonatator have lips, so they can show their teeth or not. It's a important tool of communication. They combine it with tail swinging and flipper wriggle to form a huge vocabulary of gestures.
These animals wandering every summer in the antarctic waters.
