RaZias Posted April 15, 2013 Share Posted April 15, 2013 Some "brown" classic hissers I have don´t have the last section of their legs. The last section is the one that allows them to climb. Is this a genetic defect on the "brown" classic hissers ? Some hissers have theirs antennas cutted. His there a feeding problem ? I give them cat food...is it a calcium problem ?

Nicolas Rousseaux Posted April 15, 2013 Share Posted April 15, 2013 Often due to fight or oldness. Old roaches tend to loose some basitarsus, or even the complete tarsus. Quote Link to comment Share on other sites More sharing options...
Keith Posted April 16, 2013 Share Posted April 16, 2013 Yep old age or from fighting. It is common and so long as they can get around to eat wont cause any problems. Quote Link to comment Share on other sites More sharing options...
pierre72 Posted April 29, 2013 Share Posted April 29, 2013 Awe. It must be rough and there probably in pain. I had a Madagascan that had a short antennae. Did they make out o.k.? Quote Link to comment Share on other sites More sharing options...

Nicolas Rousseaux Posted April 30, 2013 Share Posted April 30, 2013 they can feel something is happening, but keep in mind the structure of their nervous system... no real brain, just a ganglion chain. There are no nerves in the legs and so on, nothing is centralised like it's the case for chordata, they can get information and every ganglion can react independently, but they're really different of us Quote Link to comment Share on other sites More sharing options...
pierre72 Posted May 1, 2013 Share Posted May 1, 2013 You're obviously more experinenced in insect science than me. I'm not scientist. It's just hard to believe they don't have feelings when my landlord bombed and I'd see them on their backs all wiggling. Also trying in vain to pull themselves out of traps, antennae wiggling rapidly in both cases. Quote Link to comment Share on other sites More sharing options...

Also trying in vain to pull themselves out of traps, antennae wiggling rapidly in both cases. They don´t feel pain. For exemple a red fish only has a 3 seconds memory, so we can´t say that they feel like us. When they wigle the antennae is more an emotional reaction (fear) than pain. About wiggling on their backs I don´t know why they do that, they are feeling something but not pain. Insects don´t have nociceptors, altough some of them have.

pierre72 Posted May 3, 2013 Share Posted May 3, 2013 O.K. thanks for the information. I wasn't trying to contradict you that last time. I posted those observations about the antennae in hope I can encourage roach-hating people who visit the page to be more sensitive with them.
