How unique is a gold lobster? About 1 in 30 million, according to Mark Hall, owner of the, in Kingstown, Rhode Island.

Earlier this week, the aquarium took in the crustacean after a local all-you-can-eat seafood restaurant called “out of the blue,” Hall said. A genetic mutation gives gold lobsters their color, the"The blue [lobster] is everybody's favorite, but there's something about the gold that really jumps out at you," Hall said. "Most people assume it's a different kind of lobster.”The rare mutation for gold lobsters isn’t to be confused with orange lobsters, Hall wrote in a Facebook post. Their orange counterparts “are slightly more common, and a darker orange color."

seafood restaurant in Charlestown donated the lobster. Within about an hour of the restaurant calling, bartender Joel Humphries delivered it to its new home, where it's now in a tank, Hall said.Humphries happens to be a former volunteer and employee at Biomes, an education facility and hands-on aquarium, which features marine animals from Narragansett Bay and the Atlantic Ocean.

The morning of May 29, about 50 fourth-grade students visited the aquarium. As Hall worked, he could hear the kids reacting to the marine life. They sounded impressed by the golden lobster, he recalled.

In its new tank, the lobster shuffled to and fro with hefty golden claws. It looked out with two piercing black eyes, videos showed.Chevrotains are also classified as ungulates and ruminants. Ungulates are simply animals with hooves. This diverse group includes well-known animals like elk, giraffes, wild boars, rhinos, camels, and bison. Ruminants are a specific type of ungulate. They are even-toed hoofed animals that chew regurgitated food. Common examples of ruminants include sheep, cows, deer, and antelopes. Millions of years ago, chevrotains were more widespread and diverse, but today only 10 species remain. These surviving species still possess many ancient, primitive features that are rarely seen in more modern mammals.

Chevrotains are remarkably small animals—about the size of a pet rabbit, cat, or small dog. In fact, they are the smallest hoofed animals on Earth. While the water chevrotain () can weigh between 15 and 35 pounds, the Java mouse-deer (

) is a mere 2.2 to 4.4 pounds. Most chevrotain species fall within the 2- to 9-pound range. Chevrotains have short, slender legs with tiny hoofed feet. They aren’t particularly agile when turning, but their small legs are efficient for running straight and moving through dense vegetation and forests.Their bodies are round, similar to those of a mouse or rabbit, with small, pointed snouts and large eyes. This unusual combination of features can cause people to mistake them for rodents. Their posture also adds to this confusion, as their longer hind legs make their hindquarters higher than their front. However, their thin legs, reddish or orange-brown coloring, and white markings make them closely resemble a deer. They also have small, pig-like hooves and long, sharp fangs.
