  1. (a) We report mean values (three to five individuals) of measurements taken from the expression of shh at the first-tooth stage in the three cichlid species: CA, Cynotilapia afra; MZ, Metriaclima zebra; LF, Labeotropheus fuelleborni. MD, mesiodistal; OB, odontogenic band; ZOI, zone of inhibition. (b) Mean values (three to five individuals) from the 3–4-teeth stage. All values are in micrometres ± SE.
