What is the difference between red nematodes, red worms and sand worms?

There are differences, the main differences are: different properties, different morphological characteristics, different growth environment, as follows:

First, the nature is different.

1, red nematode

Red nematodes are also called filariasis, water worms, red filariasis and red nematodes. It belongs to annelids.

2. Red worm

Red worms, also known as red worms, are larvae of Insecta, Diptera and Chironomidae.

3. Sandworm

Sandworm, also known as gymnosperms, also known as sandworms, starworms and so on. It belongs to starworm.

Second, the morphological characteristics are different.

1, red nematode

It looks like an earthworm larva, bright red or fleshy red, orange yellow, slender, generally about 4 cm long, and the longest can reach 10 cm.

2. Red worm

It is similar to ordinary mosquitoes, but the main difference is that the antennae are densely covered with fine hairs, just like feathers. Another difference is that its mouth (oral needle) has degenerated and does not have the function of smoking.

3. Sandworm

The body length is cylindrical, much like intestine, about 10-22cm long, naked and hairless, and the longitudinal muscles and annular muscles of the body wall are arranged in bundles and staggered, forming a square lattice pattern.

Third, the growth environment is different.

1, red nematode

Most of them live in the silt on the bank or bottom of the river, and are densely covered on the surface of the silt. One end is fixed in the sludge, and the other end extends out of the sludge and vibrates in the water.

2. Red worm

Water and stagnant water can breed a large number of larvae. Most chironomid larvae feed on organic matter in water. In the water rich in silt or organic matter, they can breed in large quantities because of the lack of natural enemies such as fish and shrimp.

3. Sandworm

Living in the sea area at the bottom of sand and mud along the coastal beach, it drills out at high tide and lurks in the sand and mud hole at low tide, hence the name "Sandworm".
