What do cephalopods use as a method of propulsion?

they expand thier mantle and draw in water, and then contract their mantle forcing the water out.

What phylum are tunicates, and lancelets in? Why is this unexpected?

Phylum Chordata. this is unusual because they are invertebrates.

What unique reproductive strategy do female crustaceans employ?

The store sperm to use with future hatches of eggs.

What is a carapace?

An armored shield that covers the anterior portion of an arthropod

What is a radula?

an organ found in mollusks, covered with hundreds of small teeth that is used for scraping food into the mouths of mollusks

What gives a tunicate it's name?

the leathery tunic it develops as an adult

What do cuttlefish use chromatophores for?

camouflage

Is this an arthropod?

Yes a decapod, even though it takes advantage of shells left behind from other animals

What does arthropod mean and give and example.

jointed foot -lobster, crab, shrimp, barnacles, copepods

Name three traits common to all arthropods.

1.exoskeleton 2. carapace 3. cephalothorax 4 females can store sperm for future eggs 5. open circulatory system

What do cleaner shrimp and wrasse do?

They set up cleaner stations where they eat parasites and other organic material off of other fish. symbiotic Mutualism

Why do arthropods molt?

They have a hard exoskeleton made of chitin, so they need to shed it and create a new one when they grow

Since echinoderms release there egg and sperm into the water, what aspect of their reproductions strategy helps them be successful?

They release their egg and sperm during a short season. Increasing the population of gametes in the water during that time. The organism can sense it

What does a sea urchin have to help it process hard to digest algae and sea grasses?

A long coiled gut (so do sea cucumbers, because they swallow sediment as they crawl along the ocean floor)

What does a sea cucumber use as a method of defense?

It eviscerates some of it's organs, and ejects them to distract an enemy while it gets away?

What does the water vascular system do in a starfish?

it is a hydraulic system, used for locomotion, food and waste transport and respiration. it operates the tube feet. in a starfish

What kind of symmetry do echinoderms have?

radial-pentamerous

What kind of circulatory systems do these organisms have? A. Gastropod, B. Bivalve, C. cephalopod

A. open B. open C.Closed

What s the common name for a gastropod, and what does gastropod mean?

Snails, Stomach-foot organisms, (coiled body organs sitting on a large muscular foot)

What is a cephalopod and give in example?

"head-foot" octopus, squid, cuttlefish

What is a mollusks foot used for?

Locomotion, anchoring and obtaining food

What is a Dorsal nerve chord?

A long bundle of nerves cells located along the dorsal part of an organism's body

What is the cephalothorax?

The anterior part of an arthropod body, consisting of a head and thorax fused together.

What is molting?

The process of shedding an exoskeleton and replacing it with a new one.

What is chitin?

A derivative of carbohydrate that provides flexibility and support. Exoskeletons are made of chitin

What is the mantle?

A sheath of tissue surround the the organs of a mollusk, producing a shell and aiding in respiration.
