The ocean is home to some of the most breathtaking creatures on Earth \u2013 and few are as stunning as these vibrant fish. Whether it\u2019s the electric hues of the mandarinfish, the regal flutter of a Siamese fighting fish\u2019s tail, or the deadly beauty of a lionfish, these species blend form and function in striking ways.<\/p>\n
Most beautiful fish<\/h2>\n

So called because of its bright, vibrant colours, the flamboyant cuttlefish\u00a0is a small, 8cm-long cuttlefish that\u00a0uses its fins to walk along the seafloor. Majestic and brightly coloured from the day it is born,\u00a0watch this video to see how the flamboyant cuttlefish hatches and takes its first steps.<\/figure>\n
Clownfish<\/h3>\n\n

Easily recognised thanks to its starring role in the Pixar movie franchise,\u00a0Finding Nemo<\/em>, the clownfish has an arresting image \u2013 an orange body punctuated with a single white stripe, that blends into black around the lower fins.<\/p>\n
Its beautiful orange and white stripes are far from the most interesting thing about the clownfish, however \u2013 in fact, this species is oceanic hermaphroditic, and the\u00a0clownfish can change sex\u00a0to complement that of their partner.<\/p>\n
Clownfish are predominantly found in\u00a0coral reefs, living in the protective cover of an anemone\u2019s tentacles.<\/p>\n
The Mandarinfish\u2019s scientific name is\u00a0Synchiropus splendidus\u00a0<\/em>\u2013 and it certainly is rather splendidus, with dazzling hues of blue, orange and green. Found in the shallow waters of the western Pacific, Mandarinfish are renowned for their spectacular dusk mating ritual, in which they show off their bright colours and raised dorsal fins.<\/p>\n
Clown triggerfish<\/h3>\n\n

With bold white spots and flashes of yellow across its body, the clown triggerfish is also known as the bigspotted triggerfish and is found in the Indian and west Pacific oceans.\u00a0Triggerfish are territorial, creating grinding noises by moving their dorsal spines in their sockets \u2013 a sound which wards off potential intruders or predators.<\/p>\n
Lionfish<\/h3>\n\n

Despite its impressive red markings and trailing fins, the\u00a0lionfish\u00a0is one of the\u00a0deadliest animals in the sea, as its fins can deliver a dose of powerful venom that can cause extreme pain \u2013 and even sometimes temporary paralysis in their victim. Found across the entire Indo-Pacific region, the\u00a0lionfish has recently been found as far as the Mediterranean Sea.<\/p>\n
The lionfish is one of the\u00a0deadliest fish in the ocean\u00a0\u2013\u00a0but is also one of the\u00a0prettiest sea creatures.<\/p>\n
While they might look staggeringly different to the other fish in this round-up,\u00a0seahorses\u00a0are indeed still fish.\u00a0Seahorses look like horses\u00a0because they hide among blades of\u00a0seagrass, with a hydrodynamic head that allows it to slip through the water without creating ripples, helping it avoid predators.\u00a0Seahorses can also change their colour\u00a0using small organs called chromatophores, which are embedded in their skin and contain several different pigments.<\/p>\n
These sea creatures aren\u2019t just unique for their horse-like appearance: seahorses also display reversed pregnancy, with the\u00a0male seahorses getting pregnant\u00a0and carrying the fertilised eggs (one of the\u00a0craziest animal births ever).<\/p>\n
Moorish idol<\/h3>\n\n

Another star of\u00a0Finding Nemo\u00a0<\/em>(Gill), the Moorish idol is named after the fishermen of Southeast Asia, who have long held a profound respect for these fish. While the yellow, black and white stripes of the Moorish idol are impressive, it\u2019s the stunning shape of these fish that mark them out from the rest. A compressed, disc-like shape is paired with a long dorsal fin, which resembles a whip, sweeping off the back of the body.<\/p>\n
Siamese fighting fish<\/h3>\n\n

While this may not be a creature of the sea, the Siamese fighting fish (also known as the red crowntail betta fish) is a majestic freshwater fish that we thought was worthy of inclusion in this round-up. Native to Southeast Asia, this is one of the world’s most beautiful fish.<\/p>\n
