The crustaceans can be found almost anywhere there is water - salt or fresh. They live in the water in many cases, but lots of varities live on land near water or moisture. There are over 50,000 different "flavors" of these critically important animals. Crustaceans are the shrimp, crab and lobsters, and there are some in places where no other creatures can stand the water because it is too hot, too salty or in some other way less than habitable. Crustaceans are found in deep caves where there is no natural light (and they are blind), in deep oceans where the only source of energy is thermal vents on the ocean floor, and most rivers and streams of any size. A link is provided to the Wikipedia article on these amazing critters, which are a subdivision of the arthropods.
What else can I help you with?
What characteristics distinguishes crustaceans from all other arthropods?
Their ten walking legs, and their split nature (biramous). All their legs are tiny pincers matching the main ones, unless the segment is fused.
What are the various movements in periopods?
Periopods are the specialized walking legs seen in crustaceans such as crabs, lobsters, and shrimps. These limbs can perform various movements such as walking, swimming, grasping, and grooming. The coordinated movement of periopods allows the crustaceans to navigate their environment, capture food, and interact with other members of their species.
How many legs does a cheliped have?
A cheliped is not a separate body part but rather a term used to describe a specific type of limb in crustaceans, such as crabs and lobsters. Each crustacean typically has one pair of chelipeds, which means they have two chelipeds in total. In addition to chelipeds, crustaceans have other legs, with most having a total of ten legs, including walking legs and the two chelipeds.
How many joints are in a crayfish's leg?
No - or, not "only" six. Lobsters belong to the order Decapoda (literally, 'ten feet'), an order of crustaceans within the class Malacostraca. Remember that the "legs" may have significant specialization and not necessarily resemble a process that the organism uses for walking - such as swimmeretes, or front claws; in this case it might seem the lobster has four pairs of legs for walking (pereiopods) and one pair for grasping and manipulating (chelipeds).
Do crustaceans have 3 pairs legs?
Crustaceans typically have more than three pairs of legs. Most crustaceans, such as crabs, lobsters, and shrimp, possess five pairs of legs, which include specialized appendages for different functions. However, some smaller crustaceans may have variations in leg count, but the general characteristic is having multiple pairs of legs.
Are lobsters crustaceans?
Yup, because crustaceans have jointed legs and segmented body. -co0leTs24
What lives in water and has many legs?
An aquatic animal that fits this description is a crayfish. Crayfish are freshwater crustaceans with many legs and are typically found in rivers, lakes, and streams.
How many legs do lobsters have?
8 for walking the other two are used for hunting. (10legs in all)
How do crustaceans move in the water?
Most Crustaceans have legs, which enable them to simply walk along the ground. Some have legs designed for swimming, and they get around that way.
How do crustaceans look?
Crustaceans have exoskeletons that protect their bodies, and these can be in range of colors, but typically they match the environment in which the organism is found. Crustaceans also have two antennae, two maxillae, biramous legs, which means they bend in two places, and a pair of mandibles, which are like jaws.
Are butterflies and wasps crustaceans?
Butterflies and wasps are not crustaceans, they are insects. They have a pair of antennae, 3 body parts and 6 legs unlike crustaceans that have 2 pairs of antennae, varied number of legs and body segments.
Invertebrate group with exoskeletons and jointed appendages?
Phylum arthropoda are also called jointed legged animals. They have exoskeleton and segmentations. Some good examples are crustaceans, insects and arachnids. Examples of crustaceans are crabs, crayfish, and lobster.
