Legs, or appendages. The forward pair have adapted to become claws, which are more arm-like than the others. Lobsters, along with crabs, prawns and shrimp, are decapods (10 legs).
Appendages attached along the underside of the abdomen that are used by lobsters and crayfish for swimming and reproduction?
These appendages are called swimmerets, and they play a crucial role in locomotion for lobsters and crayfish, helping them to swim and navigate in the water. In addition to aiding in movement, swimmerets also serve a reproductive function by allowing females to carry and protect their eggs until they hatch.
Do lobsters have a notochord?
Lobsters do not have a notochord. Instead, they belong to the phylum Arthropoda, which is characterized by a segmented body, an exoskeleton, and jointed appendages. The notochord is a feature of chordates, a separate group that includes vertebrates and some invertebrates. Lobsters possess a different type of support structure, primarily relying on their exoskeleton for protection and support.
What organisim is a arthropod?

What are lobster feelers called?

How big is a lobsters tentacles?
Lobsters do not have tentacles; instead, they possess long antennae and smaller appendages called antennules. The long antennae can reach lengths of up to 10 inches (25 cm) or more, depending on the species. These sensory organs help lobsters navigate their environment and detect chemical signals in the water. The antennules are shorter and serve similar sensory functions.
What are some physical characteristics of a lobster?

What are the first animals to have appendages and what are appendages?
appendages are how many body parts do they have
How many jointed legs do arthropods have?
The number of legs varies by species. Hexapoda like the insects have six; decapoda like lobsters and crabs have ten (including specialized appendages); myriapods like millipedes may have over 700.
