The appendages on the underside of a crustacean are called "pleopods" or "swimmerets." These structures are primarily used for swimming and can also play a role in reproduction, as they may assist in carrying eggs. In some species, they can vary in size and function, depending on the sex and developmental stage of the crustacean.
Crabs, and the clawlike appendages are called chilipeds.
Mantis
Palps are a second pair of appendages found in crustacean and insects. These appendages are located near the mouth and are used to guide food into the mouth.
The two body sections of a typical crustacean the head and the abdomen, to which appendages are attached. By contrast, a typical insect has a head, thorax and an abdomen.
A squid has ten appendages. A squid's appendages are arranged in five pairs. The longest pair of appendages, the fourth pair, are called tentacles or feeder arms.
I would have to say appendages. And I like you ;)
The underside of a mushroom is called the "gill."

Crayfish are members of the crustacean family.
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.
Crustacean eggs are typically fertilized externally. During mating, males transfer sperm to the female, often using specialized appendages. The female then releases the eggs into the water, where they are fertilized by the sperm. This method allows for a large number of eggs to be fertilized simultaneously, increasing the chances of survival for the offspring.
