From shegetsoff, the growing organism

Homarus Gammarus, or the common lobster, is rumored never to senesce.[1] She'd be something of a trophy, a real conversation starter. She won't respond to bait, she doesn't fall for traps, and she'll clamp through your fingers without hesitation, so you'll need to use a net. Keep her tank empty or she'll find somewhere to hide. She wont play with the toys you give her anyway. But if you stroke her tail and starve her long enough, she might take food from you.

She still hasn't molted yet. She's more calcium than meat at this point. Pushing the back of the knife with your palm, break open her claws, revealing tender insides. It might sound like screaming, but it's just air escaping the exoskeleton.[2]

Pet ownership isn't all it's chalked up to be. Even the smallest tank eats up too much power. Toss her back to the river.
