Problem Description:

The task is to classify the given invertebrate animals into different categories based on their characteristics. The categories provided are:

1. Arachnid
2. Crustacean
3. Insect
4. Miscellaneous
5. Mollusk
6. Worm

Solution Approach:

To solve this problem, we need to identify the characteristics of each animal and match them with the appropriate category. Here’s a breakdown of the classification criteria for each category:

#### 1. Arachnid:
- Typically have eight legs.
- Examples: spiders, scorpions, ticks.

#### 2. Crustacean:
- Have a hard exoskeleton and usually live in water.
- Examples: lobsters, crabs, shrimp.

#### 3. Insect:
- Have six legs and three body segments (head, thorax, abdomen).
- Examples: butterflies, ants, grasshoppers.

#### 4. Miscellaneous:
- Animals that do not fit neatly into the other categories.
- Examples: jellyfish, sea anemones, starfish.

#### 5. Mollusk:
- Soft-bodied animals, often with a shell.
- Examples: scallops, mussels, clams.

#### 6. Worm:
- Long, soft-bodied animals without limbs.
- Examples: roundworms, tapeworms, leeches.

Classification of Each Animal:

#### Arachnid:
- Tarantula: Spider-like creature with eight legs.
- Black Widow Spider: Spider with eight legs.
- Scorpion: Eight-legged arachnid with a stinger.
- Tick: Eight-legged arachnid that feeds on blood.

#### Crustacean:
- Lobster: Hard-shelled marine crustacean.
- Shrimp: Small, hard-shelled crustacean.
- Crawfish: Freshwater crustacean similar to lobster.
- Crab: Hard-shelled marine crustacean with claws.
- Krill: Small, shrimp-like crustacean.

#### Insect:
- Ant: Six-legged insect with a segmented body.
- Butterfly: Six-legged insect with wings.
- Grasshopper: Six-legged insect with jumping legs.
- Beetle: Six-legged insect with a hard exoskeleton.
- Daddy Long Legs: Six-legged insect (technically an arachnid but often grouped with insects in basic classifications).

#### Miscellaneous:
- Octopus: Soft-bodied cephalopod with tentacles.
- Jellyfish: Gelatinous marine organism.
- Sea Anemone: Fixed marine organism with tentacles.
- Starfish: Star-shaped marine organism.
- Walking Stick: Insect-like creature that resembles a stick.

#### Mollusk:
- Scallop: Shelled marine mollusk.
- Mussel: Shelled freshwater or marine mollusk.
- Clam: Shelled marine mollusk.

#### Worm:
- Roundworm: Long, cylindrical worm.
- Flatworm: Flat, ribbon-like worm.
- Leech: Segmented worm that sucks blood.
- Tapeworm: Long, segmented parasitic worm.

Final Classification Table:
