Unless otherwise, both the taste and the texture of crayfish and lobster is equal. Crayfish refers to a nocturnal freshwater crustacean that resembles a small lobster and inhabits streams and rivers while lobster refers to a large marine crustacean with a cylindrical body, stalked eyes, and the first of its five pairs of limbs modified as pincers. The crayfish belong to three families: Cambaridae , Astacidae , Parastacidae while lobster belongs to the family Palinuridae.
Crayfish live mainly in Northern America but is found in all parts of the world while lobsters live in Europe, Northern America, and Australia. Furthermore, the crayfish live in freshwater while lobsters live in saltwater. Crayfish eat worms, insects, and plants while lobsters eat small fish, prawns, clams, and snails. Crayfish is a small freshwater decapod with large front claws while lobster is a comparatively large, saltwater decapod with large front claws.
Crayfish is not much colorful while lobsters are colorful. The main difference between crayfish and lobster is their size and their habitat. Their abdomens are also composed of several segmented stacks, to which the said appendages are attached. However, in terms of habitat, you can almost always tell the difference between the two. Together with the shrimp family, lobsters dwell in almost all types of seas or oceans. Conversely, crayfishes are the crustaceans that live in freshwater environments, like creeks, rivers and even lakes.
Specific locations where they dominate are the Northern Americas, some Asian spots, and European and Australian regions. Secondly, the crayfish, otherwise known as the crawfish, is said to be shorter than the average clawed lobsters. Adult sized crayfishes can reach lengths of 10 to 15 cm. On the contrary, lobsters can stretch longer, up to 5 to 10 cm more, or 20 cm at an average.
If they are not harvested, sometimes lobsters even grow a lot longer. Overall, although lobsters and crayfish are typically the same crustaceans in terms of body structure, they still manage to be different in two major aspects:. Lobsters live in saltwater habitats, whereas crayfish live in freshwater environments.
Lobsters are generally the longer crustacean version when compared to crayfish. Cite APA 7 ,. Difference Between Lobster and Crayfish. Difference Between Similar Terms and Objects.

Now you know the characteristics of both crustaceans, it's important to know how to tell the difference between the two so, when in doubt, look out for the following: A lobster has two large pincers or claws whilst a crayfish doesn't.
A crayfish is reddish in color whilst a lobster is bluish, greenish or brownish. American lobsters have a darker brown or green color, while those in Europe have a deep shade of blue. Their joints are more colorful, with specks of orange or red. In addition to their five pairs of legs, lobsters are known for their unequal, yet large claws.
They protect them against predators, as well as attack, catch and tear their prey. It helps tear up their food. A fun fact is that lobsters can grow a new claw if one gets cut off. In adult lobsters, this can take place once or twice per year for 5 to 7 years.
During that time, they have to remain vigilant of predators since their outer covering is soft and vulnerable. Crayfish are freshwater crustaceans. They can be found in lakes, rivers, creeks, streams, and dams. They burrow under grass beds, rocks, and in crevices. Lobsters are considered marine animals. They can be found in cold oceans and seas. Young lobsters that are still settling on the bottom burrow in sand, clay, and pebbles. All crayfish can burrow under logs and rocks to stay hidden from predators.
Yet once they feel threatened, they use their tails to quickly swim back to their burrows for safety. Lobsters are also mainly nocturnal. They hunt for their food at night and remain inactive during the day. But if threatened, they can retreat quickly to escape their predators. They fan out silt and debris and create a modified entrance using rocks and pebbles.
To prepare for molting, they may even block the entrance for up to two weeks as a measure of protection.
