Monsters Of The Circle Sea: Giant Sea Snakes
If you were to sail 200 miles due south of Black Pig Island, you would find the low and swampy island cluster known as the Snake Islands. It is here that the Giant Sea Snakes come to mate, rear their young and then leave those young to mature. Aside from Fishing Bats, no mammals live on these islands, nor do any ground nesting birds or reptiles. Between the inhospitable nature of the islands and the sea snakes, things will probably stay that way.
A newly hatched Giant Sea Snake is three feet long and about as thick as a broomstick. They grow quickly, fed on small fish and large insects while guarded by both their parents. When, at the age of two months, they reach a length of about seven feet, the parents leave them to fend for themselves.
It takes around a year for the young snakes to reach a length of twenty feet. Only then do they leave the island and go out into open water. They will take another two years to reach their full adult size of fifty feet long and four feet thick.
Giant Sea Snakes are not poisonous, but do have a large mouth full of razor sharp teeth. They are fast and aggressive hunters who will eat nearly anything they can swallow whole, including humanoids. It is not unknown for a Giant Sea Snake to attack a small boat in hopes of knocking a couple of crewmen overboard. Needless to say, most sailors give a wide berth to any snakes they might see.
Giant Sea Snakes live for at least 30 years and are reckoned to be as intelligent as dogs.
