Like Sea Breams, there are many different Emperors. They look a lot like
Snappers, and are closely related, the difference being Emperors are species from
the family Lethrinidae and Snappers are from the family Lutjanidae. Just to further
confuse, there is a fish called Emperor Snapper although it is a member of the
Lutjanidae family. Ranging from 300g to 1kg,varieties of Emperor include
Longnose, Snubnose, Spangled (also known as Capitaine or Blue Emperor), and
Yellowtail.
When it comes to the flesh and cooking, while Emperor doesn’t have quite as
strong a flavour as Snappers, it can be cooked in the same way.
