Poisonous worms are worms that produce toxic substances. These include some free-living marine annelids (annelids), which have poisonous bristles or are equipped with poisonous hooks on their jaws.
Polychaete worms, such as fireworms, have poisonous bristles. They use them for protection and hunting. Poisonous hooks on the jaws are found in leeches, such as jaw leeches. They help these worms stick to the victim and eat it.
The venoms of poisonous worms can cause irritation, inflammation and even paralysis in the victim. They pose a danger to humans upon contact. Some tropical species of fireworms and leeches are especially poisonous. Therefore, when swimming in tropical seas, care must be taken to avoid being bitten by these worms.
Poisonous worms: the nature of the poison and its importance for human health Worms are multicellular organisms that play an important role in the ecosystem of our world. However, some types of worms can be dangerous to humans. This post describes the types of worms that produce toxic substances and their importance to human health. One of the first forms of life on Earth were sponges, the ancestors of many modern species of plants and animals. About 70% of terrestrial echinoderm species belong to the phylum Coelenterates. The main trend in the evolution of the chordate type is ectodermal innervation (nerve elements - neuropodia of the surface layer of the body). At the same time, in evolution there is a “change of energy generator”: if in the evolutionary series of ciliates the primary biological form of movement was gliding, then in worms an anterior gonad (respiratory ring) appears, and then respiratory propulsors.
