de Queiroz AC, Sakai Y, Vallinoto M, Barros B.
PMID: 27547571
PeerJ. 2016 Jul 26;4:e2268. doi: 10.7717/peerj.2268. eCollection 2016.

The general morphological shape of plant-resembling fish and plant parts were compared using a geometric morphometrics approach. Three plant-mimetic fish species, Lobotes surinamensis (Lobotidae), Platax orbicularis (Ephippidae) and Canthidermis maculata (Balistidae), were compared during their early developmental stages with...
