Fun Spaghetti Worm Facts For Kids

The spaghetti worm (Eupolymnia crasscornis) is quite simply a worm that looks like spaghetti. Spaghetti worms are segmented and have a tube body and translucent white tentacles.

Their tube bodies are generally submerged into the sand or floor of the sea. The only thing visible is the translucent tentacles.

These tentacles are utilized by spaghetti worms for feeding purposes, mostly detritus. Spaghetti worms are native to the western central Atlantic Ocean. They are most common in the waters off the coasts of Puerto Rico, Florida Keys, and Bermuda.

They prefer tropical and intertidal waters. These marine invertebrates are at the bottom of the food chain and are easy prey for fish, gastropods, and crabs.

During swarming or mating, the males and females do not have to be in close vicinity of each other, instead, the females kick off the reproductive process via pheromones. Spaghetti worms are absolutely harmless in personal aquariums too.

What is a spaghetti worm's habitat?

How do they reproduce?

Spaghetti worms reproduce via sexual means and swarming. A pheromone is released by the females into the saltwater to attract and signal to the males to shed their sperm. The shedding of the sperm by the males induces the female to shed their eggs.

This particular behavior is called swarming. The gametes are spawned when the body wall ruptures. After the eggs are fertilized, they become planktonic. There are some eggs that remain in the tubes of the worms or they are burrowed in jelly-like masses on the tubes.

The eggs become larvae, and the larvae later metamorph to become juveniles. The juvenile stage is where the body tube lengthens. And finally, the juveniles become adults.

What is their conservation status?

The conservation status of the spaghetti worm species is Not Evaluated by the International Union for Conservation of Nature.

Spaghetti Worm Fun Facts

What does a spaghetti worm look like?

Spaghetti worms have segmented bodies. The only part that is visible is the translucent or white tentacles that extend out of the burrow and onto the floor of the sea.

These tentacles can be over 3.3 ft (1 m) long. Spaghetti worms wrap these tentacles around food and draw it closer to their mouths. Spaghetti worms also possess internal and external lips for gathering food.

This way of feeding has been adopted by spaghetti worms to avoid gastropod and fish predators. The burrows of spaghetti worms are also shared by animals like the tube pea crab. Spaghetti worms utilize three-branched gills pairs for breathing purposes.

The gut of spaghetti worms is well-developed and it consists of a fore-stomach, an esophagus, a hind-stomach, a closed circulation system, and an intestine. The tubes of spaghetti worms are made of mucus and can be colored cream, pink, white, brown, or beige.

You can also simply move them on to another tank. Spaghetti worms are at the bottom of any food chain, even in a personal tank.

Predators like fish or crabs, particularly arrow crabs, will get rid of spaghetti worms quickly. In the case of a reef tank, aggressive wrasses work well too.

How do spaghetti worms get oxygen?
