I have a light spotted sea cucumber which has expelled it internal organs which should i keep?

This is a cucumber which isn't supposed to do this. Could it be another kind mistaken for the light spotted. It looks just like the Holothuria hilla (light-spotted). Now, which part should I keep in my salt water tank? I know that a part is very toxic. Is it the internal (I think so, but not positive) Thanks for you imput!|||Check this out|||i think you should put it back in the ocean where it belongs and try getting a dog something that is suppoused to be in a house!!!|||ok well do you mean that it spit out its organs? usually when sea cucumbers are frightened, to protect themselves, they spit out their organs so when the predetor tries to eat the organs they get a bad taste of it and go away....meanwhile the cucumber is hiding in a cave or a dark place where it can regrow its organs....and of course all ekinoderms can regrow their body parts....so yea....so you might wanna put a sea cucumber in a tank wher there is a little cave or something it can hid in for a couple months....
