Fun Spaghetti Worm Facts For Kids
Gallery
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.

How many spaghetti worms are there in the world?
It is unclear exactly how many spaghetti worms there are in the world since their population has not been evaluated.
Where does a spaghetti worm live?
Spaghetti worms are found mainly in the western central Atlantic Ocean, from northern Brazil to Central America. They are also very common in Puerto Rico and Florida Keys. The shallow Bermudan coastal waters also are home to spaghetti worms.
What is a spaghetti worm's habitat?
Spaghetti worms are found at the bottom of the sea, close to sand and rocks. They make a burrow in the sand which is where they make a tube-like structure. They are found exclusively in tropical ocean saltwater, in the tidal and intertidal regions.
Who does spaghetti worm live with?
Spaghetti worms are solitary creatures. They get together with females to procreate in the breeding season.
How long does a spaghetti worm live?
It is not clear exactly how long spaghetti worms live but they may possibly live for four to seven years.
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.
How cute are they?
Spaghetti worms are rather plain animals. The only endearing thing about them is that their tentacles sometimes form a star shape on the sea bottom, the diameter of which is around 23.6 in (60 cm).
How do they communicate?
Spaghetti worms communicate via pheromones.
How big is a spaghetti worm?
Spaghetti worms have a body tube length of 5-6 in (12.7-15.2 cm) and their tentacles can be about 3.3 ft (100 cm) long. This makes them three times smaller than bearded fireworms.
How fast can a spaghetti worm fly?

They themselves are preyed upon by gastropods, fish, blue stripe butterflyfish, wrasses, arrow crabs, and other crabs. Angelfish are possible predators too.
Are they dangerous?
No, spaghetti worms are not dangerous.
Would they make a good pet?
Spaghetti worms have no aesthetic or commercial value. They may inadvertently find themselves in personal tanks, but they are harmless in that setting as well.
Did you know...
Spaghetti worms have enzymes that help them to digest food quickly.
Although spaghetti worms are harmless, if they increase in number too quickly, it is easy to rid the tank of them. One can limit the amount of food that they receive as this will make them reproduce at a slower rate.
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?
Spaghetti worms make use of the three pairs of gills they have for breathing. The branched gills are actually on a small red mass on the left side of their heads. This gill system supplies them with oxygen.
Are spaghetti worms good or bad?
Spaghetti worms are good and they are harmless. The only common inconvenience is that they may move around on corals causing them to close, but spaghetti worms do not eat corals.
Even if they multiply quickly, they do not become an issue. A spaghetti worm reef tank is a good thing since they eat detritus and stuff that they do not consume becomes food for algae.
