Eek,
I hope invertebrates don't feel pain. I guess thats why we don't need IACUC permits to feed our plants. Very cool sequence of events. Thanks for the neat and descriptive photos.

so...u mean that you pull off one of the wings of a butterfly or a fly....it doesn't feel anything? Basically no nervous input? It should feel something. Just becos we don't know doesn't mean that they don't FEEL. lol! I don't want to get in a flame topic..but I feel that we just don't have enough data to say that insects don't feel. I don't know about the insect nervous system.....but I would assume that there has to be some system whcih allows it to co-ordinate movement of its body and if one of these links is severed or if its exoskeleton ruptured and its body contents being removed....it should be able to FEEL it.

Hope I did not start a heated topic ;D. I agree that there is not proof that insects do not feel pain. However, there are some studies supporting the invertebrate no pain hypothesis. Notice they use the word "probably" in their conclusion. See the following website for references: philosophy.tamu.edu/~gary/ee/pain.htmlWhen I was in grad school in entomology we discussed how if you pull an insects leg of it will continue walking. If I remember correctly we even did some experimentation with this and measured the walking velocity between those with legs pulled off and those with all legs attached and found no statistical difference in there velocity. You pull a dog/cat/human leg off we are not going far. This does not suggest invertebrates do not feel pain. However does suggest differences in our responses to "damaging stimuli". Modern cephalopods are viewed differently in the invertebrate world due to presence of a nervous system and brain. I'm not saying that insects an other invertebrates do not feel pain. I was just making the statement that we are not required to have an animal care permit to experiment with or feed our plants insects. V |

lol! I agree....that I am glad that we do not need to have permits to feed insects to our plants. lol! or that it would be a case of torturing the insect life. However... yeah! as you said..... its just a "PROBABLY". Personally....I don't like killing insects unless I absolutely need to. For example...I would much rather prefer capturing it and throwing it outside than squishing it for 2 reasons.... 1) Want to avoid cleaning up the mess 2) Just feels un-necessary to kill something. |

Of one thing I am certain, your Drosera leaf doesn't "feel" hungry after that meal! Great shots!
Take care,
Steve
