Difference Between Bairdi and Opilio Crabs

Difference Between Bairdi and Opilio Crabs

Humans are smart, adaptive creatures who have always found a way to survive. Our earliest civilizations were established close to the seashores because humans can only live off seafood for so long before they needed land and other food sources too! Fish, crabs, and oysters have been eaten by humans for a very long time. It is possible that people living in the early days had different categories for the fish.

Crabs have been a staple in our diets for generations. They come from all over the world and there is something to suit every taste, though some varieties may be more common than others!

The Opilio crab and Bairdi crabs are both popular, but there’s a lot of variety in their features. These two crabs have been key players in the world’s belly for centuries. The Bacardi crab is known as the yellow-shelled invertebrate while its cousin Opilio holds the title as orange one shells or harvestmen.

Opilio Vs. Bairdi Crabs

The contrast in size between Opilio crab and Bairdi Crab makes them so different. The larger, more robust creature will always be found in greater numbers than its smaller counterpart. The larger variety, in general, will be a Bairdi while smaller ones can only come from an Opilio crab.

Comparison Table Between Opilio and BairdiCrabs

Parameters of Comparison Bairdi Crab Opilio Crab
Size The Bairdi Crab, also known as the Bigger Crabs or simply just big ones for short, is about three times larger than opilio crabs. Opilios are comparatively smaller in size.
Capturing Method The best methods for catching these crustaceans have changed with time, with more people taking crab pots Opilios are a delicacy that can only be caught using the trawling method.
Meat Content The Bairdi crabs are known to have a higher content of meat. Opilios have a comparatively lesser content of meat.
Flavor The flavor of the Bairdi Crab is a little more on the sweet side. Opilio crabs are not sweet.
Appearance These crabs have shorter tails. They have 4 pairs of longer legs.

What are Bairdi Crabs?

The Bairdis are a type of crustacean found in Earth’s oceans. These crabs can be found around the North Pacific Ocean and are smaller than other types. The Bering Sea is a famous fishing territory within the Pacific Ocean for catching Bairdi crabs.

The lifespan of the Bairdi ones is approximately 10 years and it can weigh up to 1.8 KG in weight! It is scientifically known as Chionoecetes Bairdi, but it’s also known by its popular name of ” Tanner crab.”

The female Baridis spends 12 months incubating before hatching. Once born, it can float for a little while but loses the ability after two months and settles down at sea bed where they feed on worms or clams until late summer when prey becomes harder to find due to rising temperatures.

The Baridi crab has a sweet taste that some people find too subtle while others enjoy it quite well. This type of crustacean is caught using the Crab pot, which was invented in the 1950s by George Est Tatlock who called his invention “crab pots.”

Crab pots are a popular method for fishing crabs, but they can also be used to trap other animals. These cages or baskets have food items that attract the crab into it and once inside you’ll capture your prey!

The Bairdi Crab is a smaller variety of the Chionoecetes genus. Though it can be difficult to tell them apart for their size, Baridis have shorter tails than other varieties and also tend towards being bigger with more meat content per crab eaten on average!

What are Opilio Crabs?

The opilio snow crab is seen in the Bering Sea and has been known to us as ” Snow Crab.”

Opilio crabs, scientifically known as the Chionoecetes opiloides which are known as “opies” fish markets. They’re caught by trawling technique and have a shorter tail than Bairdi’s species of crab which makes them easier for catching.

Opilios are better than Bairdi Crabs. It’s easy to find them and the males can be upped by two times as compared with females of this species, reaching 1-1/2kgs on average! At maximum, a female opi Liocichla will only weigh about half a kilogram (or 16 ounces).

Opilio crabs can live up to six years. They feed on worms while larger annelids like octopuses prey upon them when available. The Opilio crab’s diet varies depending on its size; some individuals eat mostly smaller organisms such as crustaceans or mollusks, whereas others take more meaty meals of other types too.

The crab is an interesting and versatile meat-based food. The color of its shell varies from white at the bottom with orange or red accents, making it appear larger than other types found in other parts of the world. It also has four pairs that allow for better traction when walking on land so they can move around freely.

Watch out for opilio crabs during the new year. These little guys can be trapped in large numbers and their jumbo-sized claws are razor sharp!

Difference Between Bairdi and Opilio Crabs

The Opilio and Bairdi crabs are both crustaceans, but the difference between them lies in their meat content. The “Bairdi” has more of it than an Opilios does!

While Bairdi Crab’s short tail makes him quick and nimble, Opilio has a much longer one that gives him more power.

The difference between the two crabs’ methods of capture is quite notable. The Bairdi ones are caught with a pot, but Opilio can be caught with traditional fishing techniques like trawling or netting them up on land first before taking off into water where they will swim around seeking out other small animals for dinner!

There is a difference in the size of the Crabs as well. The Bairdi crab is slightly larger than an Opilio one, and it’s also worth noting that these two species live in different locations too!

Though it is not easy to find Crabs in every season, they are consumed for their sweet flavor. Bairdis have this while Opilio doesn’t-a taste that’s hard to beat!


There’s not much to choose between Opilio and Bairdiwhen it comes down to their similarities. They both live in the same areas, eat similar food items. However, one thing that does separate them? The meat content; with more fat found within these smaller crabs than what can be found elsewhere on your plate!

The Opilios, an uncommon crab found in the oceans of India, is smaller than most other species. The females can only grow as large as 4 inches while males are 6-8 inches long but they still have plenty to offer when it comes down to sweet flavor and pure taste. Furthermore, both male and female opilio go through 10 stages before transforming into an adult after molting once from larva into adulthood.
