  1. Lutjanus ehrenbergii (Peters, 1869)

    Ketabi, Ramin; Jamili, Shahla
    Lutjanus ehrenbergii is known as Blackspot snapper and Black-spot snapper. L. ehrenbergii is widely distributed in the Indo-West Pacific at depths ranging from 5 to 20 m. This reef-associated species inhabits very shallow coastal habitats, often in large schools near freshwater run-offs. Adults inhabit coral reefs, while juveniles frequent inshore areas over sand, silt or coral rubble bottoms, occasionally in mangrove-lined streams and estuaries. This species may enter freshwater areas to consume small fish and invertebrates. This species reaches sexual maturity at approximately 2 years of age and reaches a maximum age of at least 11 years. Growth trajectories are...
