Sea Cucumber ID?

[SeaCucumberFan]

I want to know what cuke this is, I've had it since May or earlier. Side question: What are those spikes for?

P.S. Sorry for sideways picture

I'd say Holothuria edulis

No, it does not have pink coloration and it has anal teeth

Maybe Holothuria spinifera!

Holothuria spinifera has a cylindrical body, dark brown on the upper side and pale brown beneath. The skin is densely covered with sharp conical protuberances.
