# data[].attributes.body
General characteristics: Symmetry and Size, Body wall, Nervous system

Three examples: Enoplea, Ascaridida, Secernentea

Classes (classification) with marine examples: Ecdysozoa

# data[].attributes.body
General characteristics: mostly parasitic, ladder-type nervous system, have underground cephalization.

Three examples: tapeworms, flukes, turbellaria

Classes (classification) with marine examples: Platyzoa

# data[].attributes.body
General characteristics: Echinoderms are characterized by radial symmetry, several arms radiating from a central body. The body actually consists of five equal segments, each containing a duplicate set of various internal organs.

Three examples: starfish, sea urchin, sea cucumber

Classes (classification) with marine examples: Deuterostome

# data[].attributes.body
General characteristics: Unsegmented soft body with bilateral symmetry. Presence of an internal or external shell.

Three examples: squid, octopus, cuttlefish

Classes (classification) with marine examples: Lophotrochozoa

# data[].attributes.body
General characteristics: They possess a chitinous exoskeleton that must be shed during growth.

Three examples: insect, arachnid, crustacean

Classes (classification) with marine examples: Ecdysozoa

# data[].attributes.body
General characteristics: They are multicellular organisms which are sedentary in nature. Most of them are marine while a few are freshwater forms.

Three examples: sponge, demosponge, hexactinellid

Classes (classification) with marine examples: Parazoa

# data[].attributes.body
General characteristics: They are mostly unicellular, but some, like algae, are multicellular. Kelp, or 'seaweed' is a large multicellular protist that provides food, shelter and oxygen for numerous underwater ecosystems.

Three examples: Chromalveolata, Excavata, Amoeba proteus

Classes (classification) with marine examples: eukaryotic organisms that cannot be classified as a plant, animal, or fungus.
