Question 1

What do you call a pole with a hook on the end used in fishing? Pteronura brasiliensis (talk) 13:30, 13 October 2011 (UTC)

A fishing pole alexandra.m.avila (talk) 08:49, 17 October 2011 (UTC)

Nope. This item does not have any fishing line attached to it. Pteronura brasiliensis (talk) 19:57, 17 October 2011 (UTC)

A fishing gaff. bibliomaniac15 06:37, 19 October 2011 (UTC)

Hurray! A point to Bibliomaniac! Why don't you stick around for a bit until mire people join? Pteronura brasiliensis (talk) 13:23, 19 October 2011 (UTC)

Question 2

This fish dish has an extremely basic pH. What is it? bibliomaniac15 06:58, 20 October 2011 (UTC)

Lutefisk? Pteronura brasiliensis 13:16, 20 October 2011 (UTC)

Yessir. 1 point to you. bibliomaniac15 18:00, 27 October 2011 (UTC)

Question 3

This fish parasitizes freshwater mussels. Pteronura brasiliensis 16:14, 28 October 2011 (UTC)

Bitterlings? KatieHutch (talk) 01:31, 6 December 2011 (UTC)

Indeed. I hope you will stick around so we can get this quiz going again. Your turn for a question.Pteronura brasiliensis 16:55, 11 December 2011 (UTC)

I hope some more people join as well! :) KatieHutch (talk) 19:39, 13 December 2011 (UTC)

Question 4

While we think of fish as mainly scaly creatures, they also have hair cells. Where are the two main areas these cells could be found? KatieHutch (talk) 19:38, 13 December 2011 (UTC)

The semicircular canals and the lateral line, maybe? I don't know how specific you want. Pteronura brasiliensis 01:14, 15 December 2011 (UTC)

Yup! I would have even just taken the ear and lateral line. :) Your question. KatieHutch (talk) 18:23, 15 December 2011 (UTC)

The gills? Vorbee (talk) 20:56, 9 January 2019 (UTC)

Question 5

This commonly-known warm-blooded fish that lives in the Pacific is vulnerable and quite often illegally fished. Their name is due to the color of their fins, which are retractable. They are usually larger than all other species of their family. Pteronura brasiliensis 14:28, 16 December 2011 (UTC)

Atlantic bluefin tuna, Thunnus thynnus. Koumz (talk) 17:20, 20 January 2012 (UTC)

Welcome back! You are incorrect, however. Note: "that lives in the Pacific". Pteronura brasiliensis 21:40, 20 January 2012 (UTC)

Ouch. I should have paid better attention. Your question seems to point toward the Pacific bluefin tuna, Thunnus orientalis, but the IUCN lists it as "Least Concern" right now, so that seems not to match the "vulnerable" portion of the question. The Southern bluefin tuna, Thunnus maccoyii, is critically endangered, but it is usually smaller than the Pacific bluefin. Koumz (talk) 00:41, 21 January 2012 (UTC)

Hm. It is the Pacific bluefin. I thought it had been vulnerable. Or maybe I took that from the article itself, not the official listing. However, you get a point, congratulations, and again, welcome back. Pteronura brasiliensis 01:13, 21 January 2012 (UTC)

This is a great fish to ask a question about because I think many people don't realize when eating tuna what a huge fish a tuna really is. I was actually thinking of a question along those lines myself, but you beat me to it. Koumz (talk) 01:40, 21 January 2012 (UTC)

I was going to say "Pacific bluefin" then saw some one had already put this answer down. Vorbee (talk) 20:57, 9 January 2019 (UTC)

Question 6

Fish in this group (one common name that refers to several different fishes in several different genera) each have a crustacean for a roommate. Koumz (talk) 22:56, 22 January 2012 (UTC)

Sorry, just I haven't been able to find anything like that. I'll keep trying, though. Pteronura brasiliensis 18:04, 10 February 2012 (UTC)

The fish are named after the crustaceans, and the crustaceans in turn are named after a weapon (because they use one claw as a weapon to catch food in a unique manner). Koumz (talk) 21:12, 10 February 2012 (UTC)

Some gobies live together with alpheid shrimps. Lycaon (talk) 14:45, 24 February 2012 (UTC)

Alpheids would be the pistol shrimps, and the gobies they live with are thus shrimp gobies or prawn gobies, genera Amblyeleotris, Cryptocentrus and others. Point to you. Koumz (talk) 21:45, 24 February 2012 (UTC)

Of course it would be pistol. Grr, I had been thinking some sort of Medieval weapon. Pteronura brasiliensis 16:37, 27 February 2012 (UTC)

Question 7

Volunteering! So what are the subgenera of the genus of fish which is known especially for having a large part of their diet being plain wood? Pteronura brasiliensis 18:07, 19 March 2012 (UTC)

The page for Panaque, which is known for xylophagy, lists Scobinancistrus and Panaqolus as subgenera of Panaque, although this does not appear to be accepted in either FishBase or Catalog of Fishes. There would also have to be (by definition) a subgenus Panaque as well if there are other subgenera. Couldn't resist this question. Koumz (talk) 19:22, 19 March 2012 (UTC)

Woah! That was somewhat prompt. The answers you gave were what I was looking for, so good work. Your turn. Pteronura brasiliensis 19:47, 19 March 2012 (UTC)

Question 8

This fish has a skeleton made up mostly of cartilage, but it is not a member of Chondrichthyes. It has no known close relatives. The juvenile form, which has pelvic fins, is so different from the adult form, which has no pelvic fins, that they were thought to be different species for a long time. Koumz (talk) 10:24, 31 March 2012 (UTC)

Ocean Sunfish (Mola mola) have a largely cartilaginous skeleton and odd looking juveniles. They may fit the bill here. I once counted seven specimens during a ferry trip from Palma de Mallorca to Barcelona! Lycaon (talk) 07:15, 9 April 2012 (UTC)

Mola mola shares a number of characteristics with the fish in this question, including scalelessness and a jellyfish-heavy diet. But Mola mola has some fairly close relatives, including a congener (Mola ramsayi) and three other species in the family Molidae. The fish in question is the only member of its family, and in some classifications, even its own order. It has no fin spines. Koumz (talk) 16:02, 9 April 2012 (UTC)

Then it must be the enigmatic Ragfish :-). Lycaon (talk) 20:30, 9 April 2012 (UTC)

Exactly! Koumz (talk) 22:04, 9 April 2012 (UTC)

Question 9

Name a magazine whose photos have started a means of classifying catfishes. Pteronura brasiliensis 04:29, 13 February 2013 (UTC)

This would be the German aquarium magazine DATZ (Die Aquarien und Terrarienzeitschrift) that created the L-number system. Koumz (talk) 15:51, 12 March 2013 (UTC)

Correct! Pteronura brasiliensis 16:41, 14 March 2013 (UTC)

Question 10

Name the substance that some freshwater perch have in their eyes that enables them to see well in lowlight conditions so they can ambush other fish. USERNONGRATA208.54.40.146 (talk) 14:31, 24 January 2014 (UTC)

Porphyropsin. Koumz (talk) 17:15, 6 March 2014 (UTC)

Would the answer be Tapetum_lucidum? RawrSean (talk) 19:06, 21 August 2014 (UTC)
