No, not all crustaceans have 10 legs. Most crustaceans have ten legs, including crabs, lobsters, and shrimps, but there are some crustaceans that have fewer than 10 legs. For example, some species of copepods (a type of crustacean) have only six legs, while some belostomatids (giant water bugs) have only four legs.
Additionally, some species of spiny lobsters have 18 pairs of legs, which means they have 36 legs in total. So the answer is no, not all crustaceans have 10 legs.

How many legs do crustaceans have?
Crustaceans are a diverse group of arthropods that include lobsters, crabs, shrimp, and barnacles. They have one of the most complex body plans of all arthropods, and each type of crustacean can have different characteristics.
In general, crustaceans are usually found in aquatic habitats and most have a segmented body and two sets of antennae. They also have many sets of jointed legs that vary between species in terms of their function and number.
The number of legs in crustaceans can range from four to over forty. Many crabs and lobsters, like the American Lobster, have four pairs of walking legs and a set of claws, with the one in front being larger.
The walking and swimming legs of a lobster are usually used for both collecting food and for propulsion in the water. On the other hand, shrimp typically have five pairs of legs, which are used for swimming and also for filtering food from water.
Barnacles, which are sessile animals, have up to twenty or more pairs of legs that they use to grab food particles and to attach themselves to rocks and other surfaces.
Overall, crustaceans have many different types and numbers of legs, with the exact number and function of each depending on which species the crustacean belongs to.
What creature has 15 legs?
The creature with 15 legs is called a Hexapus. Hexapus is a rare species of octopus which can have either six or two extra appendages, giving it between 8 and 16 legs. This unique species has been observed in depths of 300 meters in the Mediterranean.
The Hexapus’ notochord and neural structures provide evidence of their evolutionary history and how they diverged from their relatives. Scientists are particularly interested in this rare species because this could provide insight into how octopus species evolved over time.
How many legs does a lobster have 10 or 12?
A lobster typically has 10 legs: two claws, five pairs of walking legs, and three pairs of swimming legs. The two claws are the most visible and are typically the largest, followed by the five walking legs, and then the three pairs of swimming legs.
Lobsters also have two small antennae on the top of the head, and two small antennae underneath. Lobsters use their legs to walk and swim, and their claws to catch and hold onto food. The lobster is a remarkably well-adapted aquatic creature that has changed little over millions of years.
What qualifies as a crustacean?
A crustacean is any member of the large euarthropod subphylum called Crustacea. This subphylum includes lobsters, crayfish, crabs, shrimp, and barnacles. They share a common strong jointed exoskeleton, made up of either calcium carbonate or chitin, with specific parts and muscle attachments.
Crustaceans also have the classical three-part body structure: cephalon (head), thorax, and abdomen. Furthermore, they have two pair of antennae, compound eyes, and two pair of mandibles. Crustaceans are further divided into seven classes, of which the two most common are two classes: Malacostraca and Branchiopoda.
