  1. 1. Crustaceans have limbs that are split into two branches that are usually segmented. Both branches are connected to the primary segment.
    2. Most crustaceans are scavengers who feed on dead sea creatures on the ocean floor. These crustaceans usually feed at night and spend the day in ocean crevices.
    3. When crustaceans hatch from eggs, they form nauplius larvae which do not resemble their adult forms. The larvae float on the ocean surface where they feed and grow.

  2. 1. There are anywhere between 40,000 and 100,000 different species of Crustaceans across the world.
    2. Crustaceans reproduce sexually, and their eggs go through multiple stages of metamorphosis before becoming developed adults.
    3. Crustacean's diets vary widely depending on their size and variety of animals around them. Smaller terrrestrial ones will feed on decaying organic matter. Parasitic Crustaceans feed on their host's blood and flesh, and larger crabs and lobsters feed on worms, muscles, smaller crabs, etc. using a stalking technique.

  3. 1.Crustaceans are arthropods. Their skeletons are on the outside of their body.
    2.Hermit crabs can't make their own shells. They hide in shells that other sea animals left behind.
    3.Crabs and shrimp can swim. Lobsters just scuttle about on the bottom of the ocean.

    1. What happens if a hermit crab can't find a shell that fits? Does he get depressed? Does he get eaten easily? ????????????? YAHVVSHVH

  5. 1.Crustaceans have six to eight legs. They also have antennas on their heads that are used to navigate in their environments and sense location, potential danger and food.
    2. Crustaceans are made up of 5,000 species.
    3. When dealing with freshwater the most likely crustacean you will find would be the crayfish.

  6. 1.When lobsters mate, the eggs aren't fertilized right away. The female carries the male's sperm and chooses when to fertilize her eggs.

    2.When food is scarce, lobsters can turn cannibal and dine on smaller lobsters.

    3.Lobsters eat voraciously after molting, and will often consume their own recently emptied shells. Eating the old shell replenishes lost calcium and hastens the hardening of the new shell.
