The structure of the skull of Slavoia suggests that it may have had a fossorial (burrowing) lifestyle,[4][5] and when fully grown, it likely grew up to 12 centimetres (4.7 in) long.

[6] Slavoia is known from several specimens including the holotype ZPAL MgR-I/8,[3] mostly made up of incomplete skulls and skeletons, and it has therefore been possible to reconstruct its appearance.

The lacrimal bone was greatly reduced, and there were 26 presacral vertebrae, equipped with an anteriorly hollow vertebral centre (procelus).

[5] Alifanov (1993), Gao and Norell (2000), Kearney (2003) and Bolet et al. (2022) placed Slavoia within Scincomorpha.

[11] Tałanda (2016, 2017), who provided a new description of the genus, placed it as a stem-group relative of amphisbaenians within Lacertoidea.
