Non-vore stuff:

They are soft and rubbersish, except the scales, which are rock hard.

They are an asexual species that reproduce through fragmentation. Specifically with a razor made of a special mineral on their planet.

Since there wasn't any sex to begin with in their case(I'm talking about physical body parts), gender didn't develop as a thing either. So they are genderless creatures

Polyamory is the normalized form of relationship because the cut-off piece(s) in the first minute of separation from the origin body can be combined with others, without a particular limit on how many. So the more parents the offspring has, the better it is believed to grow, both physically, having more data to combine, and mentally, parents having fewer issues managing the child.

Vore stuff:

Generally it is a very normal practice on their planet, especially for protection... Or a way to flirt.

Their inner flesh is mostly about the same color as the outer, except it glows.

Acid immune, therefore, basically undigestible.

They can control their digestion, as well as shapeshift themselves an extra stomach, whatever fits better in a situation

Can change their size(obviously)
