SCP Foundation

These creatures aren't difficult to contain, they'll behave tame and relaxed as long as the room is big enough (10x10m/32ft or more). Different Stones or Crystals can be fed to them at any time if one of the specimens appears to be hungry.

The first three specimen of SCP-xxxx-1 were found in ████-Russia. A group of teenagers saw them flying around, caught one (the other two followed) and showed them to the inhabitants of the village. The other two were born in containment.

This SCP is about 50cm/19,6 inches long and weights around 10kg. It has a big, oval head and one big eye in the middle of it. While normally holding it's head like a human it will turn it's head up horizontally to eat and mate.
It's arms are extremely big compared to the rest of the body and are about double it's size while the legs are almost non-existent. It rarely uses it's arms to walk on the grund and mostly floats around, the way it achieves this has yet to be found out. It's skin and eye coloration is a light blue. It doesn't posess pupils.

SCP-xxxx-1 seems to live off minerals i stones and crystals. If one of said objects is small enough it will swallow it whole, rapitly digesting it with an acid of unknown composition. If the object is to large to swalliw it will spit acid on it until it breaks into smaller pieces. This liquid is highly dangerous for any human or animal, that's why SCP-xxxx-1 should only be touched with thick gloves.

The alien is neither hostile nor really sentient, it is about as intelligent as a Cat. there are no recorded cases of a specimen attacking someone.

All of the five aliens in containment have found to be male due to the incident with SCP-xxxx-2

I am not sure if i should call it SCP-xxxx-1 and -2 since the second one is a female. It was found floating around near the Area the males were contained and seemed extremely nervous. It looked exactly the same except for posessing two large claws on each hand. it didn't seem to produce acid.
When it was brought into the others room the three "normal" ones started drippin a lot of acid and bit SCP-xxxx-2 a few times. After that they started behaving normal again and xxxx-2 didn't seem to be hurt in any way. SCP-xxxx-2's abdomen kept growing and it was suspected to be either pregnant or ill. It was decided to put it into a seperate room and a few days later it vomited out two small male Aliens. They were able to float and produce acid from the beginning. it seemed that SCP-xxxx-2 had died during this event.
