Question 1
This question is about two related (in the same order) families of strange and interesting fishes. The fishes in both families carry their own light with them (the light is made by bacteria). One family has its lights under its eyes, the other on its jaws. The common name of one family comes from a tool used by humans. The other family has two common names, both after plant products (one is a fruit, the other is another kind of seed carrier). Name the two families. Koumz (talk) 14:06, 15 September 2011 (UTC)
 * Three answers. First the flashlight fish, Anomalopidae, then the Pinecone fishes, Monocentridae, then the Magic Schoolbus. Pteronura brasiliensis (talk) 01:08, 16 September 2011 (UTC)
 * The Magic School Bus ..... OK, whatever! Your other 2 answers are correct. Koumz (talk) 21:55, 16 September 2011 (UTC)

Question 2
This fisheries biologist has coauthored two different books. He was also born in Canada. Pteronura brasiliensis (talk) 23:43, 18 September 2011 (UTC)
 * Ray Hilborn. Koumz (talk) 14:56, 19 September 2011 (UTC)
 * Yep. Pteronura brasiliensis (talk) 17:44, 19 September 2011 (UTC)

Question 3
This ichthyologist founded a well-known hobby magazine (and the company that publishes it), but was more recently well known for legal troubles. Koumz (talk) 19:15, 19 September 2011 (UTC)
 * Herbert R. Axelrod. Pteronura brasiliensis (talk) 01:18, 20 September 2011 (UTC)
 * That is correct. Koumz (talk) 04:43, 20 September 2011 (UTC)

Question 4
This strange fish was discovered in 1997 when it was found in a market place and had pictures taken of it, and online experts decided it might not be the other member of the genus. Pteronura brasiliensis (talk) 12:50, 20 September 2011 (UTC)
 * "Raja laut" (Indonesian coelacanth), Latimeria menadoensis. The other coelacanth, Latimeria chalumnae, has a similarly interesting discovery story. Koumz (talk) 13:28, 20 September 2011 (UTC)
 * That is correct. Pteronura brasiliensis (talk) 17:00, 20 September 2011 (UTC)

Question 5
The Latin name of this fish is after the Boy Scout leader who discovered it in Canton in the 1930's. Koumz (talk) 12:48, 21 September 2011 (UTC)
 * The White Cloud Mountain minnow (Tanichthys albonubes) Pteronura brasiliensis (talk) 12:58, 21 September 2011 (UTC)
 * That is correct. Koumz (talk) 14:44, 21 September 2011 (UTC)

Question 6
This thing is an internal structure only found in some fish found on top and on the bottom of the esophagus. Pteronura brasiliensis (talk) 15:23, 21 September 2011 (UTC)
 * Leydig's organ. Produces red blood cells in elasmobranchs only. Koumz (talk) 16:09, 21 September 2011 (UTC)
 * That is correct. Pteronura brasiliensis (talk) 19:05, 21 September 2011 (UTC)

Question 7
This family contains the only fishes that are both venomous AND electrogenic. Koumz (talk) 19:38, 21 September 2011 (UTC)
 * Perhaps the stargazers, Uranoscopidae? Pteronura brasiliensis (talk) 19:51, 21 September 2011 (UTC)
 * That is correct. Koumz (talk) 20:18, 21 September 2011 (UTC)

Question 8
The Oarfish is also commonly known as the King of Herring. But it seems that the herring have another king as well. What is the fish? Pteronura brasiliensis (talk) 00:32, 22 September 2011 (UTC)
 * I found multiple sources, including FishBase, saying that Chimaera monstrosa, a large ratfish, is called this. FishBase also says that the name "king of herrings" or "king of the herrings" is used in the UK to refer to the deal fish Trachipterus arcticus.  I found another source saying that an older dictionary called the opahs (family Lampridae, relatives of the oarfish) by this name.  The largest of all the herrings is the Dorab wolf herring, Chirocentrus dorab, so it might be considered a "king" for that reason.  I also found one online source that said the Allis shad, Alosa alosa, is called "King herring" in some parts of the UK. Koumz (talk) 03:57, 22 September 2011 (UTC)
 * Was looking for Chimaera monstrosa. Pteronura brasiliensis (talk) 12:44, 22 September 2011 (UTC)
 * That is correct. Pteronura brasiliensis (talk) 12:44, 22 September 2011 (UTC)

Question 9
Back to electric fishes again. I wrote a paper on them in college. This fish is the only member of its order that has a waveform (continuous) electric discharge. It is also the only member of its family. Koumz (talk) 12:47, 22 September 2011 (UTC)
 * Are you talking about the African Knifetail (Gymnarchus niloticus)? Pteronura brasiliensis (talk) 12:58, 22 September 2011 (UTC)
 * I've seen it more often called Aba or Aba aba, but you are correct. Koumz (talk) 13:24, 22 September 2011 (UTC)

Question 10
This genus of fish is often called "-yside" even though they are living fishes. "-y" is a product of a sea creature that is not a fish. What does "-y" stand for and what is the genus ? Pteronura brasiliensis (talk) 20:20, 22 September 2011 (UTC)
 * Maurolicus, the pearlsides (or pearlysides). Koumz (talk) 22:59, 22 September 2011 (UTC)
 * Actually I'll give you the point. I was looking for another pearlside. But, just for the kicks, can you name the other one that I was looking for? Pteronura brasiliensis (talk) 01:37, 23 September 2011 (UTC)
 * Argyripnus iridiscens. Koumz (talk) 03:06, 23 September 2011 (UTC)
 * That is correct. Pteronura brasiliensis (talk) 03:37, 23 September 2011 (UTC)

Question 11
This family of flattened South American freshwater fishes is named after a musical instrument. For an extra challenge (if you want one), name as many other families as you can which are also named for musical instruments. I count at least 6 families (not including the one the main question is about) (5 musical instruments, including 1 percussion, 2 strings and 2 brass). Koumz (talk) 12:52, 23 September 2011 (UTC)
 * OK here goes. Main one the banjo catfish, (Aspredinidae), then the trumpetfish, the cornetfish, the temperate basses, the guitarfish, and the drumfish. Pteronura brasiliensis (talk) 13:32, 23 September 2011 (UTC)
 * I had forgotten about the "bass" part, which could apply to many families (but strictly I don't think those are actually named for the instrument, especially since it's pronounced differently). There is also Banjos banjos, the Banjofish, of family Banjosidae, which may or may not actually be named for the banjo.  Your main answer is correct.  Trumpetfishes are Aulostomidae, cornetfishes are Fistulariidae, drums are Sciaenidae, Rhinidae is the very interesting-looking bowmouth guitarfish, and Rhinobatidae are the "other" guitarfishes. Koumz (talk) 13:52, 23 September 2011 (UTC)

Question 12
Name the navy ship named after this well-known fish that is one of the fastest fish in the oceans. The name of this fish is from a prey-herding device that is part of its body. Pteronura brasiliensis (talk) 22:21, 23 September 2011 (UTC)
 * There have been two submarines named USS Sailfish after the two members of the genus Istiophorus, which can reach speeds of over 65 mph. Koumz (talk) 22:30, 23 September 2011 (UTC)
 * That is correct. Pteronura brasiliensis (talk) 01:04, 24 September 2011 (UTC)

Question 13
This family contains fishes that share a name with a Gershwin character. Koumz (talk) 04:50, 24 September 2011 (UTC)
 * Sparidae, the Porgies. Pteronura brasiliensis (talk) 13:54, 24 September 2011 (UTC)
 * That is correct. Koumz (talk) 17:20, 24 September 2011 (UTC)

Question 14
This organization's acronym is the same as the name of a fish in the family Sparidae. The fish is well-known and heavily fished. It was discovered in 1766 and is in a genus of only two fish. Pteronura brasiliensis (talk) 18:29, 24 September 2011 (UTC)
 * Society for College and University Planning, acronym SCUP, shared with the scup, Stenotomus chrysops. Genus and species names should be italicized, names of families, orders, or others should not. Koumz (talk) 19:08, 24 September 2011 (UTC)
 * Sorry. That is correct. Pteronura brasiliensis (talk) 19:44, 24 September 2011 (UTC)

Question 15
Name as many fishes as you can that are named after ruminants. You have already named the cow sharks and the bull shark on an earlier question, but there are several others. The one you must get is a red and black fish found along the California coast. There are at least 2 other individual fishes, plus at least one whole family. Koumz (talk) 00:58, 25 September 2011 (UTC)
 * Yes one family yeah right I count at least 5 that is going to be tricky. Pteronura brasiliensis (talk) 16:58, 10 October 2011 (UTC)
 * There may be 5 families of ruminants, but not 5 families of fishes named after ruminants (There is one family of fishes that are all named after the same ruminant, plus one other family where many, but not all of the fishes are named after a ruminant (not the same one as the first family)). Some you can dismiss quickly (there is no "antelopefish", or anything with odd names like that). Concentrate on the common ruminants. I'll actually specify Bovidae in this case, since all the ruminants in the question happen to be from that family. Koumz (talk) 19:28, 10 October 2011 (UTC)
 * The goatfish, the cowfish, the buffalofish, the bullhead sharks, the aforementioned bull and cow sharks all work. However you mean the California sheephead, Semicossyphus pulcher. Pteronura brasiliensis (talk) 20:04, 10 October 2011 (UTC)
 * Point to you. There are also a number of other fishes called bullhead, including several catfishes, as well as the Sheepshead minnow, the Sheepshead porgy, and the Freshwater drum, which is also known as sheephead. Koumz (talk) 22:01, 10 October 2011 (UTC)

Question 16
What genus of fish produced individuals who have been swimming along the Pacific coast since before the California Gold Rush but could end up on your dinner plate tomorrow? Pteronura brasiliensis (talk) 01:50, 11 October 2011 (UTC)
 * Sebastes. Koumz (talk) 03:05, 11 October 2011 (UTC)
 * Aye point to ye. Pteronura brasiliensis (talk) 13:22, 11 October 2011 (UTC)

Question 17
The fishes of this order are often fished for even though their meat is too bony to be good as food. The order contains only two genera. The latin name of one of the genera means "large eye". The 7 fishes in the other genus have a common name that refers to their average weight. Koumz (talk) 14:09, 11 October 2011 (UTC)
 * Ah at first you said 6 fish in the genus, which got me confused. However, now that you've changed it, I'll say Elopiformes. Pteronura brasiliensis (talk) 22:13, 11 October 2011 (UTC)
 * The order page for Elopiformes said 6 species until I changed it, but Elopidae had all seven, so that's where the confusion came from. Point to you. Koumz (talk) 22:18, 11 October 2011 (UTC)

Question 18
This extinct fish was partially driven into extinction by fishermen who introduced new species of fishes into this fish's habitat. The new fishes included a fish that ate the eggs of the original fish. It was found in New Hampshire. Pteronura brasiliensis (talk) 23:15, 11 October 2011 (UTC)
 * The silver trout, Salvelinus agassizi. Koumz (talk) 03:32, 12 October 2011 (UTC)
 * This is true. Pteronura brasiliensis (talk) 12:51, 12 October 2011 (UTC)

Question 19
This Australian fish is known for grinding its teeth when caught. It has two dorsal fins, one of which is long and sickle-shaped. Koumz (talk) 18:25, 12 October 2011 (UTC)
 * The Old wife, Enoplosus armatus. Pteronura brasiliensis (talk) 18:58, 12 October 2011 (UTC)
 * That is correct, and you are the winner. Congratulations.  I will set up a new tournament, but I probably won't play again for a little while at least. Koumz (talk) 19:10, 12 October 2011 (UTC)
