Is éard is na cianabaictéir ann ná fíleam de bhaictéir uatrófacha Ghram-dhiúltacha, ^[1] ar féidir leo fuinneamh bitheolaíoch a fháil trí fhótaisintéis. Tá colainn cosúil le halga acu agus struchtúr ceallach (prócarótach) cosúil le baictéar. Tagann an t-ainm "cianbhaictéir" nó "cyanobacteria" ó dhath na mbaictéar (Gréigis: κυανός (kyanós) gorm),^[2]^[3] atá mar an gcéanna mar bhunús leis a hainm coitianta algaí gormghlasa,^[4]^[5]^[6] cé nach bhfuil siad aicmithe go heolaíoch mar algaí. Is cosúil gur tháinig siad ó dhúchas ó thimpeallacht fionnuisce nó talún.^[7]

Is dócha gurb iad na cianobaictéir an tacsón is líonmhaire dá raibh riamh ar an Domhan agus na chéad orgánach arb eol a tháirg ocsaigin.^[8] Trí ocsaigin a tháirgeadh agus a scaoileadh mar fhotháirge fótaisintéise, meastar gur iompaigh na cianabaictéir an t-atmaisféar luath, a bhí ar bheagán ocsaigine ( atmaisféar dhí-ocsaídithe), go hatmaisféar ocsaídeach, is cúis leis "An Ocsaídiú Mór" agus "meirgeadh an Domhain",^[9] rud a d'athraigh go mór comhdhéanamh foirmeacha beatha ar an Domhan.^[10]
