Talk:Predatory dinoflagellate

message: Not all parasitic algae are carnivorous; some grow on plants instead of animals.
Parasitic algae are an economically important issue where fish are reared commercially or kept in aquaria at a high density and result in high mortality in affected fish populations. A study on ornamental fish from export farms in Sri Lanka found that on average 18.4% of all fish were infected with parasitic algae. Ciliates such as Ichthyophthirius multifiliis invade the gills and form trophonts visible as white spots feeding on their victim's skin (Ichthyophthiriasis or white spot disease). Other ciliates causing invasive infections in freshwater fish include for example Chilodonella, Hemiophrys, Ophryoglena, and Tetrahymena species. In marine fish, the disease is caused by Cryptocaryon. Clownfish disease or Brooklynellosis is caused by another marine ciliate, Brooklynella hostilis. Dinoflagellates such as Piscinoodinium cause gold dust disease in fish.
This material will be included in a future article on parasitic algae, or perhaps the Algae article itself.--♦♦♦Vlmastra♦♦♦ (talk) 20:05, 13 January 2008 (UTC)
replies: text: I disagree with the whole carnivorous versus predatory versus parasitic "problem." A carnivore is simply a flesh-eating creature. A predator kills its prey. A parasite lives on its host without killing it. Both predators and parasites can be carnivores. If these statements (which I am basing on biology textbooks as well as scholarly literature) are considered wrong, I would like to see references saying that they are wrong. It appears I'm the only one who actually provided any references to the discussion on this page so far. - tameeria (talk) 05:27, 22 January 2008 (UTC)
replies: text: So shall we consider all parasitic organisms carnivorous? Are pathogenic bacteria carnivorous? Or yeasts like Candida? Or even dodder or mistletoe? --♦♦♦Vlmastra♦♦♦ (talk) 02:02, 23 January 2008 (UTC)
replies: text: That is twisting my words around for the sake of rhetoric. All I'm saying is that some parasites are carnivorous. Of course that does not apply to all parasites. Some dogs are poodles, but that does not mean all dogs are poodles. Here's an excerpt from scholarly literature: "Of 15 carnivorous parasitic insect clades..., six were more diverse than their predaceous or saprophagous sister groups,..." (Wiegmann et al., "Diversification of carnivorous parasitic insects," Am. Nat. 1993, Vol. 142, pp. 737-754) If carnivorous insects can be classified into carnivorous parasites (feeding off living hosts), carnivorous predators (killing their prey) and carnivorous saprophages (eating dead animals), I would assume the same might apply to other groups of flesh-eating organisms as well. Your point of "a parasite is not a carnivore" does not apply to all parasites and can be refuted with examples from scholarly literature. I have yet to see you come up with a reference to support your opinion on this. - tameeria (talk) 20:11, 23 January 2008 (UTC)

text: Can you please clarify your intentions for the deleted section? As far as I can tell, you deleted it because "ciliates are not algae" and then you say above that the deleted section is going to be included either in the algae article or one on parasitic algae. That is directly contradictory to the reason you gave for removing it in the first place. I don't see it anywhere and I have a feeling if I go ahead and use it to create an article on parasitic algae, it will just prompt a repeat of the "ciliates are no algae" discussion. - tameeria (talk) 14:15, 6 March 2008 (UTC)
replies: text: I must have missed that. No, of course the material does not belong in an algal article. How about Ciliate? --♦♦♦Vlmastra♦♦♦ (talk) 14:25, 7 March 2008 (UTC)
thread_title:  Extra 

message: Two articles exist that seem to discuss predatory habits of protists. As algae are not protists, the article should not be named as such. Perhaps merge the articles and have a short section on how the media has inaccurately referd to predatory dinoflagellates as "algae"? Anxietycello (talk) 02:26, 20 July 2008 (UTC)
