Chordodes formosanus is a horsehair worm that has the praying mantis as its definitive host. Horsehair worms are obligate parasites that pass through different hosts at various stages. These worms can grow up to 90 cm long and can be extremely dangerous for their host, especially the praying mantis.[1][2]
Chordodes formosanus is morphologically similar to Chordodes japonensis. Both species have the same six cuticular structures of areoles on the surface, the significantly longer filaments on the female crowned areoles. Female horsehair appears to have a round and slightly swollen posterior end of their body, while males have a narrowed end.
The definitive host range of horsehair worms is limited to one or few species. Because nematomorphs are sometimes found after they have emerged from their host, definitive information on hosts is unknown in some species.
Reproductively, they are dioecious, with the internal fertilization of eggs that are then laid in gelatinous strings. Adults have cylindrical gonads, opening into the cloaca. The larvae have rings of cuticular hooks and terminal stylets that are believed to be used to enter the hosts. Once inside the host, the larvae live inside the haemocoel and absorb nutrients directly through their skin. Development into the adult form takes weeks or months, and the larva moults several times as it grows in size.
A new study published in Biochemical Journal finds that the tubeworm, also known for its bioluminescence, is found to have a ferritin with the fastest catalytic performance ever described, nearly eight times faster than that of human capabilities.
Ferritin is an important protein found in nearly all living organisms as it manages iron metabolism in cells by storing and releasing it in a controlled manner. In humans, it is critical to iron storage and iron metabolism, helping balance iron in the blood.
This study was funded by the Air Force Office of Scientific Research (grant no. FA9550-17-0189), which is interested in learning more about the unique bioluminescent properties of the worm, the outstanding performances of the worm ferritin, and the resilient properties of the tube encasement, within a larger framework studying biomimetic systems.
Researchers at Scripps Institution of Oceanography at the University of California San Diego have made a discovery with potential human health impact based on a study of parchment tubeworm, the marine invertebrate Chaetopterus sp., that resides in muddy coastal seafloors.
A new study published today in Biochemical Journal finds that the tubeworm, also known for its bioluminescence, has a ferritin with the fastest catalytic performance ever described, nearly eight times faster than that of human capabilities.
Ferritin, present in nearly all living organisms, is an important protein that manages iron metabolism in cells by storing and releasing it in a controlled manner. In humans, its function is critical to balance iron in the blood.
This discovery also has important human health implications for biomedical research, as ferritin is an essential protein for those with iron deficiency and overall iron metabolism issues. This discovery can be a new tool in future research of ferritin to use in patients, thanks to its biocompatibility and ability to carry, protect and deliver small molecules as medication to specific targets.
De Meulenaere describes ferritin as being shaped like a soccer ball, with openings that take up iron when available, store it and release it when needed. That specific structure allows for a wide range in applications, from medical to environmental. It could help target medication release, function as a safe contrast agent, while also being used for water treatment by selectively taking up and storing contaminants.
The iron "worm" tool is similar to a large corkscrew. With a handle attached, it would have been used to insert or remove wadding from a long tube, perhaps even a ship's a cannon.
This "worm" was found buried on Preble House property on Great Cranberry Island. Among his many enterprises, William Pitt Preble built and salvaged ships on the island.

Metal atoms, which are incorporated into the protein structure of the material, play a decisive role. They make the material hard and flexible at the same time -- very similar to ordinary metals. Further research on this class of materials aims at producing novel, industrially usable materials in a natural way.
"The materials that vertebrates are made of are well researched," says Prof. Christian Hellmich from the Institute of Mechanics of Materials and Structures at TU Wien. "Bones, for example, are very hierarchically structured: There are organic and mineral parts, tiny structures are combined to form larger structures, which in turn form even larger structures."
It's different with bristle worms. Their jaws are extremely strong and unbreakable, but they do not contain mineral granules like vertebrate bones do. Instead, they contain metals. Of course, this has nothing to do with pure metal objects such as gold teeth or artificial hips made of titanium: The bristle worm uses metals such as magnesium or zinc in the form of individual atoms that are incorporated into a protein structure.
"On its own, the fact that there are metal atoms in the bristleworm jaw does not explain its excellent material properties," says Christian Hellmich. The typical properties known from everyday metals -- apart from their hardness and elasticity, above all their toughness -- are ultimately only created through the interaction of many atoms. Sliding surfaces are created along which the atoms move against each other. This can be investigated with so-called nanoindentation tests: A force is exerted on the material in a precisely defined way and then the resulting deformations are studied. Surprisingly, it turned out that the material of the bristleworm jaw behaves very similarly to metal.
"The construction principle that has made bristle worm jaws so successful apparently originated about 500 million years ago," says Florian Raible of the Max Perutz Labs, a joint venture of the University of Vienna and the Medical University of Vienna. "The metal ions are incorporated directly into the protein chains and then ensure that different protein chains are held together." In this way, the bristle worm can produce three-dimensional shapes from a particularly stable protein matrix.
At the same time, this structure also allows for deformation: When an external force is exerted on the material, the protein chains can slide past each other. The material allows elastoplastic deformations, rather than being brittle and fragile.
"It is precisely this combination of high strength and deformability that is normally characteristic of metals," says Luis Zelaya-Lainez, the study's lead author, who used materials science techniques to examine the tiny jaws. "Here we are dealing with a completely different material, but interestingly, the metal atoms still provide strength and deformability there, just like in a piece of metal."
Whereas industrially manufactured metals can only be produced using a large amount of energy, the bristle worm achieves a similar feat in a much more efficient way. "Biology could serve as inspiration here, for completely new kinds of materials," Hellmich hopes. "Perhaps it is even possible to produce high-performance materials in a biological way -- much more efficiently and environmentally friendly than we manage today."

The blue glow of the mucus from Chaetopterus involves a photoprotein, iron and flavins. Identity and respective role of these components remain, however, largely unresolved today, likely because of viscosity issues and inhibition of this system by oxidizers conventionally used to track bioluminescence activity. Here, we used gentle centrifugation to obtain a mucus supernatant showing no inhibition to oxidizers, allowing for further analysis. We applied conventional chromatographic techniques to isolate major proteins associated with light emission. Luminescence ability of elutriate fractions was tested with hydrogen peroxide to track photoprotein and/or protein-bound chromophore. Fractions producing light contained few major proteins, one with similarity to ferritin. Addition to the mucus of elements with inhibitory/potentiary effect on ferritin ferroxidase activity induced corresponding changes in light production, emphasizing the possible role of ferritin in the worm bioluminescence. DNA of the protein was cloned, sequenced, and expressed, confirming its identity to a Chaetopterus Ferritin (ChF). Both ferric and ferrous iron were found in the mucus, indicating the occurrence of both oxidase and reductase activity. Biochemical analysis showed ChF has strong ferroxidase activity, which could be a source of biological iron and catalytic energy for the worm bioluminescence when coupled to a reduction process with flavins.
