Selected for Google Maps and Google Earth

Pterois or Lionfish is a genus of venomous marine fish found mostly in the Indo-Pacific. Lionfish is characterized by red, white and black bands, showy pectoral fins and venomous spiky fin rays. Pterois are popular aquarium fish and are readily utilized in the culinary world. ==>


Description

Pterois range in size from 6.2 to 42.4 cm with typical adults measuring 38 cm and weighing an average of 480 g. They are well known for their ornate beauty, venomous spines and unique tentacles. Juvenile lionfish have a unique tentacle located above their eye sockets that varies in phenotype between species. 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.


Ecology and behavior

Pterois can live from five to fifteen years and have complex courtship and mating behaviors. Females release two mucus-filled egg clusters frequently, which can contain as many as fifteen thousand eggs. Studies on Pterois reproductive habits have increased significantly in the past decade.
