Pterois range in size from 6.2 to 42.4 cm with typical adults measuring 38 cm and weighing an average of 480 g.[2][3][4] They are well known for their ornate beauty, venomous spines and unique tentacles.[5][6] Juvenile lionfish have a unique tentacle located above their eye sockets that varies in phenotype between species.[5] It is suggested that the evolution of this tentacle serves to continually attract new prey; studies also suggest that it plays a role in sexual selection
