which do you save?

Great white shark, the bluefin tuna and the hagfish Hmm, definitly the great white shark. Predators are important in any ecosystem, and the great white is very predatorlike. Fur seals, bottlenose dolphins and sperm whales Hmm, more tricky this one. According to one of my fathers friends, seal taste like whale. I've never tasted seal, so I don't know if that's true, but if it is, we'd only need one. However, I don't know it this applies to all kinds of whales and seals so I'm really not sure. The fur of seals is apparantly important to the inuits and eskimoes, but the Brits are eating all the cod as fish and chips so there's not a lot of fish left and thin seals are caught in the nest of fishers in norhtern Norway. (as for overfishing, lets not mention the neighbours in the east) But, bottle-nosed dolphins, aren' those the ones they think have very sophisticated echo-location? Can't remember correct name for the algorithms they supposedly use, but I'm pretty sure they should be preserved. They use second degree something, I'm quite certain that if the whales and seals use something similar, they only use first-degree. So I'm saving the dolphins. I'm not quite sure the great white shark would agree, doesn't it prefer seals to dolphins?

In general the lower down the food chain the more important the animal is but on the other hand it has been proved that taking out the top predators will be detrimental as well. I am looking at the top predators of the land like the wolf that used to cull diseased animals but with out them the animals reproduced so much that the have become overpopulated in their own right. With that in consideration, I would go with the top predators of the ones that you gave us to chose from.

In most cases, I'd go with importance in the ecosystem. Certain animals are just too special to allow to go extinct though, tigers for example. Maybe I'd go out and rally more support so that we could save all of them.

I am glad I am not God or anyone who has to make these decisions. I would save the bluefin in the first group but I will probably get heck for it because the shark helps keep alot of fish down in numbers and so forth. The hagfish I know nothing about it and will probably find I should have chosen it. Haha. In the second group I would really be perplexed because of the aww factor. I would think there are alot of fur seals so maybe not such a problem with them. The bottle nose dolphins I think get hurt by motorboats and so they make may go to number one. The sperm whales have been a problem for years so it would be them or the dolphins I am thinking. I am probably way off.

I'm not up on all these varieties jb so whilst I was going to say get rid of the nasty man eating shark I was distracted by the gross ugliness of the hagfish. What on earth is its purpose, where does it live, and is it edible. I'll need to be filled in here before I can make an informed decision but I definitely don't fancy having a hagfish sidling up to me in the sea.

its simple!!! the one which is going to get extinct....

It is 6.30am here and while this is normally my best time of the day, I find this sort of question too much. I conclude that if I am powerful enough to decide which two are to become extinct, I am also powerful enough to determine a way to keep all three. I know nothing about the hagfish but I presume its reason for existence is as a cleaner, and therefore necessary. Tuna is a popular canned seafood, especially with dieters. The great white shark - well, here in Australia and elsewhere, it is known as a killer of humans, but all three have their place in the ocean, but I will exercise all my power to preserve all three. Fur seals, bottlenose dolphins and sperm whales. Well, I've been kissed by a seal. I've watched whales perform. Dolphins are delightful. No, I'll have to exercise my power again and keep all three. Sorry, but those decisions are not mine to make.

Hmmm, that's a difficult one! I'd have to do a bit of research and a lot of weighing up. It seems wrong (albeit practical) to consider them on their edibility and I wouldn't eat any of them anyway. Again, practically their effect on the ecosystem and benefits or detriment to other species would have to be considered.... & seals are pretty cute.... white sharks pretty majestic... dolphins intelligent... whale song soothing - no sorry, have to ponder on that some more.... but we definitely need to keep rabbits and penguins!

While Tuna are probably more important to the ecosystem, and I love eating tuna besides, I would rather give up tuna for life than consign to extinction great white sharks. These animals are just so powerful and majestic, and I wouldn't want to go though the rest of my life not eating tuna, but I would always miss knowing the sharks were out there. I love dolphins. But that is a tough one too. I would have to say dolphins even though seals are cute rand more important to the ecosystem and sperm whales are the worlds largest predator (not counting blue and balleen whales that eat plankton) so it would be a loss whatever went. It's a tough question, but I would have to save the sharks and the dolphins

This is a lousy way to decide, but I shall let the hagfish become extinct simply because I don't know what it is. Of the mammals, hm, this is really a hard decision. Since I cannot decide amongst them, I relinquish my choice to another. Wimpy, I know, but there you have it.

haha,it is very interesting!

Why are they going to become extinct? If the reason is environmental you might not have to choose since most of these share the same environment. Fix the problem for one and save them all. I couldn't pick one over the other as more valuable I believe each thing has it's purpose from the ones with aww factor to oh my god that's ugly. I also think sometimes we intervene when we shouldn't. If we had left the gypsy moths alone in this country we wouldn't have the problem we have now. They have a built in cycle that makes them ill every 7 years, it also prevents them from repeoducing for a certain amount of time..we had to get involved in trying to eradicate them and have screwed up that cycle. So I guess unless the reason is environmental caused by something we as humans caused and should correct..I wouldn't mess with mother nature, maybe she knows what she is doing. For the record I don't hate cute little seals.
