Hint	Answer	% Correct
includes crustaceans, insects and arachnids.	Arthropoda	100%
common examples include; Ragworms, earthworms and leeches.	Annelida (segmented worms)	91%
jellyfish and anemones belong to this group	Cnidaria	91%
commonly parasitic worms, hookworms, pinworms and whipworms are all examples of this group.	nematoda (roundworms)	91%
Animals with back-bones & tunicates & lancelets	chordata (vertebrates)	82%
clams, snails and octopus all belong to this group	mollusca (mollusks)	82%
Starfish, sea urchins and sand dollars belong to this group.	echinodermata (echinoderms)	55%
these simple animals anchor themselves on the seabed and feed by filtering water. They can be highly colorful.	porifera (sponges)	55%
This group of worms are relatively simple bilateral, unsegmented soft-bodied invertebrates. they lack body cavities, ciculatory and respiratory organs which restricts them to having a flatted shape.	platyhelminthes (flatworms)	45%
found everywhere in earths biosphere these creatures are best known for their ability to survive extreme conditions that would quickly kill most other forms of life.	tardigrada (tardigrades)	45%
Bootlace worms may be the longest animal on the planet at over 30 meters in length and belong to this group of worms.	nemertea (ribbon worms)	27%
These worm like creatures could easily be mistaken for caterpillars. They prey upon other invertebrates by ejecting an adhesive slime to trap them.	onychophora (velvet worms)	27%
the name of this phylum of marine unsegmented worms relates to the Greek god of fertility.	priapulida (penis worms)	27%
acorn worms are an example of this group.	hemichordata	18%
simplest in structure of all animals. Their name means "flat animals"	placozoa	18%
these microscopic & near-microscopic animals are found in freshwater environments around the world. Most are free swimming and make up an important part of freshwater zooplankton.	rotifera (rotifers)	18%
Unlike bivalve molluscs this group has hard shells on the upper and lower surfaces.	Brachiopoda (lamp shells)	9%
Small aquatic invertebrates which live in sedentary colonies.	Bryozoa (moss animals)	9%
predatory marine worms which are a major component of plankton worldwide.	chaetognatha (arrow worms)	9%
tiny parasites which live in the renal appendages of cephalopods.	dicyemida	9%
mostly sessile aquatic animals. mature individuals are goblet-shaped on relatively long stalks and have a crown of solid tentacles.	Entoprocta	9%
worm-like microscopic organisms. typically live within the detritus on the seabed and other water bodies.	Gastrotricha	9%
First recognized in 1956 these nearly microscopic animals can survive in relatively anoxic environments. Often slender to thread-like worms.	Gnathostomulida (jaw worms)	9%
this group of microscopic sediment dwelling animals are characterized by a protective outer case called a lorica.	loricifera	9%
similar to nematodes the adults are free-living but larvae are parasitic on athropods. They often coil themselves into tight balls that resemble knots.	nematomorpha (horsehair worms)	9%
Very simple and small soft-bodied animals with planula-like features.	Acoelomorpha	0%
tiny aquatic animals found living on the mouthparts of cold-water lobsters.	cycliophora	0%
Have small segmented, limbless bodies composed of a head, neck and trunk of eleven segments, unlike other small invertebrates they do not have external cilia but instead have a number of spines along the body for use in locomotion.	kinorhyncha (mud dragons)	0%
These small poorly known marine parasites are among the simplest of multicellular organisms. The adults are microscopic wormlike animals, consisting of a single layer of ciliated outer cells surrounding a mass of sex cells.	orthonectida	0%
these simple benthic worm like creatures have a simple sac-like gut but lack respiratory, circulatory and excretory systems.	xenoturbellida	0%
