Lumbriculus variegatus is a type of worm often called the California blackworm or bloodworm. These amazing worms live in shallow water areas. You can find them in places like marshes, ponds, and swamps. They are quite small, usually growing to about 2 to 10 centimeters long.

What is a Blackworm?
The California blackworm, Lumbriculus variegatus, is a freshwater worm. It belongs to a group of worms called oligochaetes. This group also includes the common earthworm. Blackworms are known for their dark, reddish-brown color. This color comes from a special pigment in their skin.
Where Do Blackworms Live?
Blackworms prefer calm, shallow waters. They often live in the muddy bottoms of ponds and slow-moving streams. They can also be found in ditches and even temporary puddles. These worms like places with lots of decaying plants. This is because their food sources are usually found there.
What Do Blackworms Eat?
Blackworms are detritivores. This means they eat detritus, which is dead organic material. They mostly feed on tiny microorganisms. These include bacteria, algae, and fungi. They find these tiny living things in the mud and decaying plants. By eating these, blackworms help keep their watery homes clean.
How Do Blackworms Reproduce?
Blackworms can reproduce in two main ways. One way is by laying eggs. Adult blackworms can lay many eggs, usually between 150 and 250 at a time. These eggs hatch into tiny new worms.
The other way they reproduce is even more amazing. It's called fragmentation. If a blackworm is cut into pieces, each piece can grow into a whole new worm! This is a special type of asexual reproduction. It means they don't need a partner to make new worms.
Amazing Blackworm Abilities
Blackworms have some incredible abilities. They can survive in low-oxygen environments. They do this by waving their tails in the water. This helps them take in more oxygen.
Regeneration: Growing New Parts
One of their most famous abilities is regeneration. If a blackworm loses its head or tail, it can grow a new one. This is why they are often studied by scientists. They help us understand how living things can repair themselves. If a worm is cut in half, both halves can regenerate. The front half grows a new tail. The back half grows a new head. This ability makes them very tough survivors.
Surviving Tough Times
Blackworms are very resilient. They can survive periods of drought. When their pond dries up, they can burrow into the mud. They then enter a resting state. They can stay like this until water returns. This helps them live in places where water levels change a lot.
