Cinnabar starfish (middle star aequalis) are known for their bright red-orange color and five-armed symmetry. But one is quickly gaining internet fame for a body part not normally associated with starfish: a well-formed tail.

Twitter user @Babyshoujo recently photographed and tweeted an image of a "thicc" starfish clinging to a rock at an exhibit at the Aquarium of the Pacific in Long Beach, Calif.

Since the photo was shared on June 30, the starfish's famous derrière has attracted hundreds of thousands of people. Many commenters have compared it to the "SpongeBob SquarePants" starfish character Patrick Star, who often proudly displays his protruding rounded bottom. However, experts are quick to point out that this "***" is not what it seems. [PHOTOS: Wonders of the Deep]

Vermilion starfish are found near the low-tide line and on rocky seafloors in the eastern Pacific Ocean, ranging from northern Baja California to Alaska, according to the Georgia Aquarium. Although starfish are often called sea stars, they are not fish. They are echinoderms that also include sea cucumbers, sand dollars and sea urchins.

And no, starfish don't have a " ***"; they have a centrally located ***, but they don't have a *** like a cartoon Patrick's Star. Nate Jaros, curator of fish and invertebrates at the Aquarium of the Pacific, told USA Today, "What we're seeing in the photo are the muscles of the starfish's arms contracting as they hold onto the rock,

"

it's because the starfish's body is vertically aligned, and gravity causes the organism's internal structure to "collapse," Jaros explained.

Jaros explains that this produces a shape similar to the human buttocks in the photo.

Previously, in March, social media users were intrigued by the theft-like illusion of a white-faced saki monkey (Pithecia Pithecia) at the Korkeasari Zoo in Finland. The monkey, named Pithecia, looked muscular, with biceps as round as an Aquarium of the Pacific starfish ***.

However, the so-called "buff monkey" is actually just furry, and a zoo representative told Live Science that the picture is of a stunning sea creature in the "Great Pacific Ocean"! 'Star' Photos: See the World's Cutest Sea Creature in Photos: Sick Starfish Becomes a 'Goo'
