The Most Beautiful Marine Creatures
Many marine species exhibit remarkably unusual appearances. Coloration in the animal kingdom serves a variety of purposes, including attracting mates, warning potential predators, and providing camouflage. Much like their terrestrial counterparts, an extensive spectrum of hues can be observed in the stunning inhabitants of our oceans. Below is a collection of some of the most beautiful marine creatures:
Royal Sea Star (Astropecten articulatus)
This colorful species can be found along the eastern coast of North America, particularly in the southwestern regions. While they inhabit depths of up to 97.5 meters, they are mostly found at depths between 21 to 30.5 meters, where they feed on mollusks. Unlike many other starfish species, the Royal Sea Star consumes its prey whole.
Blue Tang (Paracanthurus hepatus)
Blue Tangs thrive in coastal waters, coral reefs, and rocky or grassy shorelines, extending their range from New York to Brazil and even as far east as Ascension Island. They are known for the sharp spines on their tails, which are said to resemble surgical scalpels.
Leafy Sea Dragon (Phycodurus eques)
Despite their resemblance to seaweed, the Leafy Sea Dragon is a fish closely related to the seahorse. These creatures, dubbed “leafy,” are masters of camouflage, residing among seagrass and kelp in waters off the southern and eastern coasts of Australia. The flowing protrusions mimic foliage, while they use nearly transparent, delicate fins to navigate their environment. Remarkably, this exquisite marine being can alter its coloration to match its surroundings, enhancing its disguise.
Nudibranch (Nudibranchia)
Nudibranchs, informally known as sea slugs, comprise over 3,000 species found in oceans worldwide. These soft-bodied mollusks come in a dazzling array of vibrant colors and patterns. This vivid appearance serves as a defensive mechanism due to their lack of shells, allowing them to blend in with surrounding flora to evade predators. Additionally, bright colors can deter potential threats, as they typically signal that the creature may be toxic, even if they are not.
Sea Anemones
Sea Anemones are named after the terrestrial anemone flower due to their visual similarities. With over a thousand species inhabiting oceans around the globe, these creatures spend much of their time anchored to the seafloor. Their colors range from pale to bright fluorescent hues, and they have a cylindrical shape, encircled by dozens to hundreds of stinging tentacles used to capture prey and deliver neurotoxic venom.
Flower Hat Jelly (Olindias formosa)
Although the Flower Hat Jelly appears similar to traditional jellyfish, it actually belongs to the class Hydrozoa, while true jellyfish fall under Scyphozoa. Found in the Western Pacific off southern Japan, its sting is notably painful. The tentacles of the Flower Hat Jelly are translucent, featuring dark, opaque striping from the center to the edges. These tentacles emit iridescent, colorful tips, adding to its mesmerizing visual appeal, especially under ultraviolet light.
Sunflower Star (Solaster dawsoni)
This predatory species of starfish has between 8 and 16 arms, usually exhibiting red or orange colors. Its appearance is reminiscent of the sun in cartoons, and it inhabits the northern Pacific, ranging from Japan to Siberia and down the coast of North America to southern California. The Sunflower Star feeds predominantly on other starfish and is met with swift retreat from other starfish when they come into contact with this fearsome predator.
Flying Gurnard Fish (Dactylopterus volitans)
The Flying Gurnard is characterized by its large, brightly colored pectoral fins, which it typically keeps close to its body but spreads dramatically when a predator approaches. The fins’ transparency, complemented by blue spots, makes this creature particularly stunning underwater. Despite its name suggesting flight, the Flying Gurnard is bottom-dwelling, and its large fins do not assist it in swimming high off the seafloor; instead, they move in short, explosive bursts. The name “gurnard” derives from the French word “grunt,” referencing the sound produced by its swim bladder as water moves through it.
Feather Star (Antedonidae)
These unusual marine animals favor shallow waters but can also be found on ocean floors reaching depths of up to 9 kilometers. Their arms, which have feathery margins, can be used for swimming. Typically possessing five arms, Feather Stars utilize their grasping ‘legs,’ called cirri, to cling to sponges, corals, or other substrates while feeding on drifting microorganisms, trapping them in the grooves of their adhesive arms.
Nudibranchs (Nudibranchia)
Nudibranchs are a group of mollusks flourishing in oceans around the world, with more than 3,000 species recognized. Known for their striking colors, some Nudibranch species take on hues akin to their oceanic surroundings, serving as camouflage against predators. At the same time, certain varieties employ their vibrant colors to warn potential threats of their toxicity. Generally, these creatures reside on ocean floors and are not known for swimming or rapid movement, with some feeding on sponges while others consume sea slugs; most species prefer a single type of prey.
