About Sea Trolls

The Curabitur venator also known by it's common name of Sea Troll is a type of planktonic organism known as zooplankton, or animal wanderer, due to their lack of swimming ability. Sea Trolls attach themselves to the bottom of the ocean floor when it is not riding the currents.

Where can you find Sea Trolls

Sea Trolls can be found in warm coastal waters. They primarily live in the Benthic zone, which consists of the ocean floor, because they aren't great swimmers. Sea Trolls also live the Pelagic zone which consists of the entire ocean. Sea Trolls usually stay in the Neritic zone, as most sea life do, but go in to the Oceanic zone during mating season. Sea Trolls are also found in the Euphotic or Epipelagic zone, where the majority of its prey live.

How they hunt and move

Sea Trolls normally hunt at night by using its bioluminescent rod to attract small fish and shrimp. They also have one big eye that absorbs sunlight during the day and uses it to light up its eyes so it can be able to see in the dark. Sea Trolls also have two very large crab-like claws, located next to its bioluminescent rod, used for hooking and capturing small fish and shrimp that wander close to its rod. Once captured the claws begin to shrink and pull the fish or shrimp into its gaping mouth full of razor sharp teeth. Sea Trolls can swim but, not strongly; they normally drift with the current, using its small fins. But it can attach itself to the bottom of the sea floor with its suction cup foot.

What they eat & How big they grow

Sea Trolls primarily feed on small fish such as sardines, juvenile tuna, and shrimp such as the Peppermint shrimp. As the Sea Trolls begins to mature it will be able to eat larger prey such as American shad. Sea Trolls can grow up to 1 1/2 feet or larger and come in a variety of blues and greens. Once full grown they can eat larger fish such as Tilapia and have been known to eat small octopi.

Sea Trolls have a variety of ways of protecting themselves. For instance, the two crab-like claws can cut a fish in half. They also have the ability to change colors if they cannot fight back.


Sea Trolls mate every 2 months ; during this time Sea Trolls travel to the Oceanic zone to mate. They attract mates using their light rods, which ever male has the brightest light get the female; once they have found a suitable mate they grip their claws together as if holding hands, and remove their suction grip and float together rubbing their suction foot together. The suction cup foot is where reproductive organs are located.
