Worms and Eutrophic Waters

One of our readers recently requested that we share all the information we have on small black worms that live in eutrophic water. Eutrophication is a form of water pollution that occurs when excessive fertilizers run into lakes and rivers. This encourages algal bloom (the growth of algae), as well as the growth of other aquatic plants. This "bloom" sounds positive, but there are some negative environmental effects. Eutrophication usually leads to depleted oxygen levels and generally poor water quality. In addition, the sudden growth of algae and aquatic plants causes overcrowding and competition over resources like sunlight, space, and oxygen.There are a lot of worms that thrive in an aquatic environment. However, we don't know of many that prefer polluted water. Tubifex worms, or sludge Continue reading [...]

Blue Heron Devours Worm

One of our readers was visiting the University of Texas Southwestern bird rookery in Dallas when she snapped some fantastic photos. They show a blue heron fledging eating a a creature. She said there are some shallow pools in the rookery so the specimen might be enjoying a freshwater worm. She hopes we can identify the creature in question. Continue reading [...]

Aquatic Worms?

A reader of ours recently sent us a video of what looks to be a worm of some sort. He gave us no information about where he found it, it was solely the video. We did our best to get a screen shot of the video so that our many readers can share their opinions as well. We have determined, however, that this is not a worm at all. Continue reading [...]

Bristle Worms Dying in Aquarium

We received a question via the All About Worms Facebook page from a reader whose bristle worms have died in his aquarium. Actually, the worms didn't just die, but "simultaneously combusted," although presumably this can't be taken too literally, as we don't see how worms in a fish tank could be consumed by fire. The reader isn't worried about the worms themselves, but he is concerned if the death of the bristle worms is a bad portent, spelling trouble for the rest of the tank. So, essentially, the reader wants to know what it means when the bristle worms in your aquarium die. Continue reading [...]

Tiny, Skinny, Black Worms Found in Salt Water Pool

We received a question through the All About Worms Facebook page a few days ago about "a tiny black skinny worm in my salt water pool," to use the reader's exact wording. The reader lives in Florida, and also reports that the worms are unsegmented and appear to have "diamond shaped scales," but she concedes it is hard to tell if this is an accurate description of the worm's exterior. The reader was having trouble figuring out what she found, so she asked us to identify the tiny, skinny, black worm that she found in her pool. Continue reading [...]

Rearing Polychaete Worms

For reasons we can't decipher, we've received a few questions lately about rearing worms. The most recent article we wrote dealt with raising marine worms, and the question before us now has to do with rearing polychaete worms (or simply "polychaetes") specifically. (Most polychaetes are marine worms, so obviously raising marine worms and raising polychaetes are related.) What exactly our reader was asking was hard to determine, but at bottom it was about managing what might be called a "polychaete worm farm," one in which polychaetes are reared and bred. Is it possible to rear and breed polychaete worms? Continue reading [...]
