Shkenca kan\u00eb identifikuar mbi 2000 lloje kandil deti – me mij\u00ebra t\u00eb tjera q\u00eb supozohet se jan\u00eb ende t\u00eb panjohura.

Pse kandili i pavdeksh\u00ebm \u00ebsht\u00eb n\u00eb gjendje t\u00eb ricikloj\u00eb veten?

Kur duhet t\u00eb riparohet ose t\u00eb rinovohet, kandili i pavdeksh\u00ebm mund t\u00eb rithith\u00eb tentakulat e tij, t\u00eb fundoset dhe t\u00eb ngjitet p\u00ebrs\u00ebri n\u00eb fund t\u00eb detit si nj\u00eb polip.
