toward the head end of an animal with bilateral symmetry
body plan that can be divided into mirror images along only one plane through the central axis
tendency to concentrate sensory organs and nervous tissue at an animal's anterior end
fluid-filled body cavity completely surrounded by mesoderm
backside of an animal with bilateral symmetry
organism that filters small particles from water to get its food
group of nerve-cell bodies that coordinates incoming and outgoing nerve impulses
umbrella-shaped free-swimming body form of cnidarians
capsule whose threadlike tube contains poison and barbs and is discharged when prey touches a
cnidarian
nervous system that conducts impulses in cnidarians and echinoderms
in free-living flatworms, the tubelike muscular organ that can extend out of their mouth and such food
particles into the digestive tract
tube-shaped, sessile body form of cnidarians
away from the head end of an animal with bilateral symmetry
body plan that can be divided along any plane, through a central axis, into roughly equal halves
ability to replace or regrow body parts missing due to predation or damage
being permanently attached to one place
balance or similarity in body structures of organisms
disease caused by eating raw or undercooked meat, usually pork, infected with Trichinella larvae
underside or belly of an animal with bilateral symmetry
fertilized egg formed when a sperm cell penetrates an egg
animal with a solid body that lacks a fluid-filled body cavity between the gut and the body wall
nematocyst-containing stinging cell on a cnidarian's tentacle
coelomate animal whose anus develops from the opening in the gastrula
in flatworms, a cilia-lined, bulblike cell that moves water and certain substances into excretory tubules
for elimination from the body
in cnidarians, the space surrounded by an inner cell layer where digestion takes place
the pseudocoelom in roundworms; the fluid within a closed space that gives rigid support for muscles to
work against
layer of cells between the endoderm and the ectoderm that can become muscle tissue and tissue of the
circulatory, respiratory and excretory systems
continuously formed, detachable section of a tapeworm that contains male and female reproductive
organs, flame cells, muscles and nerves; breaks off when its eggs are fertilized and passes out of the
host's intestine
coelomate animal whose mouth develops from the opening in the gastrula
fluid-filled body cavity between the mesoderm and the endoderm
parasitically adapted, knob-like anterior end of a tapeworm, having hooks and suckers that attach to the
host's intestinal lining
animal with an endoskeleton and a backbone
