Dentphis

Dentphis is a genus of parasitic worms belonging to the phylum Nematoda, commonly known as roundworms. These worms are notable for their complex life cycles and their role as parasites in various vertebrate hosts, including humans. The name "Dentphis" derives from the Greek words *dent* (meaning "tooth") and *phis* (meaning "worm"), referencing the tooth-like structures found in some larval stages of the species.

Dentphis species primarily infect marine mammals, such as dolphins, porpoises, and seals, though some may also affect other marine animals or even terrestrial hosts under specific conditions. The most well-studied species within this genus is *Dentphis sagittata*, which has been documented in multiple cetacean species. The worms are typically found in the respiratory or digestive tracts of their hosts, where they can cause significant pathological effects, including inflammation, tissue damage, and reduced host health.

The life cycle of Dentphis involves multiple stages, often requiring intermediate hosts such as fish or crustaceans. Larvae are ingested by the definitive host, where they mature and reproduce, releasing eggs or larvae into the environment. Some species exhibit complex migrations within the host’s body before reaching their final location. Due to their parasitic nature, Dentphis infections can lead to economic losses in aquaculture and pose challenges for marine wildlife conservation efforts.

Research on Dentphis remains relatively limited compared to more medically significant nematodes, but studies have highlighted its ecological and veterinary importance. Understanding these parasites is crucial for managing marine mammal health and preventing the spread of infections in both wild and captive populations. Further research is needed to clarify the full range of host species, geographic distribution, and potential impacts on marine ecosystems.
