Did you know that emperor fish is not the same as swordfish?

The emperor fish (Luvarus imperialis), like its relative the swordfish (Xiphias gladius), is characterised as an oily fish that offers extensive health benefits. However, it is crucial to note that, despite the similarities in their classification as blue fish, we are talking about two completely different marine species.

Although both are part of the Luvaridae family of the order Perciforme, this is one of the few characteristics they share. We invite you to continue reading this article to further explore the different peculiarities that distinguish the emperor fish.

Differences between emperor fish and swordfish

These two species are often confused because the swordfish is also commonly called 'emperor fish'. However, it is important to consider that this term does not refer specifically to the species Luvarus imperialis, but is just another name used to refer to it in some regions.

The emperor fish is distinguished by its robust size and its unique colour, which combines grey, blue and golden shades. In addition, it is distinguished by its firmer flesh and more intense flavour compared to swordfish.


The emperor wrasse (Luvarus imperialis) is smaller in size compared to the swordfish. However, although it does not reach the dimensions of the swordfish, the emperor fish is still considerably large compared to other fish. As for its habitat, this fish is found in tropical and subtropical waters, especially in areas close to reefs and in deep coastal waters. In Spain, we can find it in the Mediterranean, and it is usually known under the name of "Beach Emperor".

On the other hand, the swordfish (Xiphias gladius) is known to be one of the largest fish found in oceanic waters. This species impresses with its size, reaching up to 4.5 metres in length and weighing around 650 kg. This fish is easily recognised by its distinctive "sword" or "rapier" shape protruding from its upper jaw. It can measure about one third of the fish's total length and gives it an imposing and unique appearance.

Features about the Beach Emperor

This fish is highly valued in international cuisine thanks to its distinctive taste and firm consistency, making it a popular choice in cuisines around the world. Rich in nutrients such as Omega 3, vitamins and minerals, emperor fish not only provides an exceptional culinary experience, but also contributes to promoting overall health and wellness.

The diet of the emperor wrasse, consisting mainly of small fish and cephalopods, is a key factor that greatly influences its unique taste and the quality of its meat. By feeding on these prey, the emperor fish absorbs the flavours and nutrients of its marine environment, resulting in very tasty meat and good texture.

Nutritional benefits

This species is classified as a semi-fatty fish, offering about 4 grams of fat per 100 grams of meat. Therefore, this moderate amount of fat contributes to its characteristic taste and texture, and makes it a healthy choice to include in our diet. Moreover, being a semi-fatty fish, emperor fish offers a balanced source of essential fatty acids, such as Omega 3. These are essential for heart and brain health.

On the other hand, due to its naturally intense and distinguished flavour, it is not necessary to add large amounts of salt to enhance its taste. This feature is very beneficial for those looking to reduce their sodium intake without sacrificing culinary pleasure.

In terms of nutritional value, the emperor fish has similarities with swordfish. In addition to omega 3 and 6 fatty acids, it provides high levels of high-quality protein. It is also an outstanding source of B-complex vitamins, such as B12, and minerals such as selenium and zinc.
