| Question | Answer |
|---|---|
| Mollusks | They're invertebrates with soft, unsegmented bodies that are often protected by hard, outer shells. |
| Gills | organs that remove oxygen from water. They are attached to the mantle and have a rich supply of blood vessels. |
| What kind of symmetry do mollusks have? Do the body parts in mollusks repeat? | they have bilateral symmetry and their body parts do repeat. |
| T or F most water-dwelling mollusks have gills | true |
| where do mollusks live | nearly everywhere on earth, mostly in oceans. |
| Examples of mollusks are: | Clams, oysters, scallops, snails, and octopuses. |
| A thin layer of tissue which covers the mollusks' internal organs and also produces their shell is: | The mantle |
| Many organs have an organ called a ? ,which is a flexible ribbon of tiny teeth. Acting like sandpaper, the tiny teeth scrape food from a surface such as a leaf. | Radula |
| When do snails go in and come out of their shells? | they go in their shells in dry conditions and come out when it's moist outside. |
| can snails live for long or short periods of time when they are sealed up in their shells? | incredibly long periods of time. |
| how do snails seal their shells? | many snails have a tight fitting plate of trapdoor on their foot that fits securely into the opening of the shell. |
| are Gastropod omnivores or scavengers? | both; some are omnivores and some are scavengers that feed on decaying material. |

| Mollusks have been in Earths oceans for how long? | 540 million years |
| The three major groups of mollusks are: | Gastropods, bivalves, and cephalopods. |
| The most numerous mollusks are the Gastropods, which include: | Snails and slugs |
| how intelligent are cephalopods? | very. They can remember things they've learned. |
| how do cephalopods get their food? | they capture it with their flexible muscular tentacles |
| what are cephalopods? | mollusks whose feet are adapted to form tentacles around their mouths |
| are octopuses and/or squids cephalopods? | yes |
| What are mollusks that have two shells held together by hinges and strong muscles? | Bivalves |
| Bivalves use what to capture food as they breathe? | Their gills |
| Bivalves are found in all kinds of what environments: | Watery environments, mostly oceans |
| Arthropods are a group of animals that include: | Insects, spiders, crabs, lobsters, centipedes, and scorpions |
| Earth has more species of arthropods then of what | All animal species combined |
| An arthropod is specifically an invertebrate that has what? | An external skeleton, a segmented body, and jointed attachments called appendages. |
| Arthros and podos mean what in Greek? | Arthros means joint and podos means foot or leg |
| What is molting? | when Arthropods shed |
| can the exoskeleton of an arthropod expand as it grows? | no |
| what is an Arthropod exoskeleton made of? | chitin |
| do most Arthropoda reproduce sexually or asexually? | sexually |
| arthropods have what kind of circulatory system? | open circulatory system: the blood leaves the blood vessels and bathes the internal organs |
| The arthropods first arose in what and now where do they live???? | 1) oceans 2) nearly everywhere |
| A crustacean is an Arthropod that has what and usually has three pairs of appendages for chewing??? | Two or three body sections. |
| Most crustaceans, such as crabs, barnacles, and shrimp, begin their lives as what?? | Microscopic, swimming larvae |
| Arthropoda bodies are... | segmented, like earthworms |
| in several groups of Arthropods, what happens? | Several body segments become joined into distinct sections with each section specialized to perform specific functions |
| many Arthropods have __________ attached to their bodies | jointed appendages |
| antenna | an appendage on the head that contains sense organs. |
| how long have arthropods been on the earth | 540 million years |
| what are the major groups of arthropods? | crustraceans, arachnids, centipeds, millipeds, and insects |
| how do crustacean larvae develop into adults | metamorphosis |
| what is metamorphosis | a process in which an animals body undergoes dramatic changes in form during its life cycle |
| how do crustaceans obtain food? | many ways; some eat dead plants and animals, some are preditors and eat animals they killed |
| what are the most well known, feared, and fascinating arachnid? | spiders |
| arachnids include... | spiders, mites, ticks, and scorpians |
| what are insects? | arthropods with three body section, six legs, one pair of antennae, and usually one or two pairs of wings |
| Nearly every kind of watery environment is home to crustaceans, which obtain oxygen through what? | Gills |
| Crustaceans thrive in what? | Freshwater lakes, rivers, and even in puddles that last a long time. |
| An arachnid is an Arthropod with only what? | Two body sections: a combined head and chest, and the abdomen. |
| Centipedes and millipedes are arthropods with a ton of what? | Body sections; Centipedes are carnivores with a hundred feet and millipedes have not exactly a thousand feet, but are herbivores. |
| What are some examples of sense organs and where are they located on an insect | eyes and antennae are examples of these, they are located on an insects head. |
| like crustaceans insects have what kind of eyes? | usually, they have two large compound eyes, which contain many lenses. |
| compound eyes are especially keen at what | seeing movement. |
| how do insects obtain oxygen | through a system of tubes which lead to openings on the insects exoskeleton. |
| each insect species undergoes one of two different types of what's? | metamorphosis |
| what are the two types of insect metamorphosis? | complete metamorphosis and gradual metamorphosis |
| how many stages are there of complete metamorphosis and what are they? | 4; egg, larva, pupa, and adult |
| what are some insects that go through complete metamorphosis? | beetles butterflies, house flies, and ants |
| what is gradual metamorphosis? | no distinctly different larval stage - an egg hatches into a stage called a nymph, which often resembles the adult insect. |
| insects eat what? | they can eat plants, but some feed on animals too. |
| fleas and mosquitoes feed on what? | blood of living animals. Mosquitoes need it to feed their young. |
| Grasshoppers, termites, cockroaches, and dragonflies go through what?? | Gradual metamorphosis |
| Insects have many defenses against predators, including what?? | A hard exoskeleton that helps protect them. |
| What is one of the most common defenses amount insects? | camouflage |
| what is a pheromone? | a chemical released by one animal that affects the behavior of another animal of the same species. |
| what do animals use pheromones for? | locate food, attract mates, and distinguish members of their own group from members of other groups |
| Most pheromones are what? | chemical compounds that are made up of long chains atoms |
| pheromones enable many animals to recognize what? | group members |
| pheromones are made in labs to do what's? | attract and eliminate pest insects |
| are there forms of chemical communication between animals besides pheromones? | yes |
| light in animals is generated by chemical reactions that take pace in what? | the organisms cells |
| Because the atoms join together in specific ways, each pheromone has a different what reaction? | Chemical |
| Bioluminescene | Is the production of light by a living organism. |

| what is a echinoderm? | a radially symmetrical invertebrate that lives on the ocean floor. It means "spiny skinned" |
| adult enchnioderms have a unique kind of radial symmetry in which... | body parts, usually multiples of five, are arranged like spokes on a wheel. |
| what is an endoskeleton and what is something that has them? | a spiny internal skeleton made of plats that contain calcium. Enchnioderms have these. |
| Enchnioderms have a an internal fluid system called what? | a water vascular system |
| the water vascular system consists of what? | fluid filled tubes within the echnioderm's body |
| Echnioderm's live where and do what | crawl on the bottom of the ocean seeking food, shelter, and a mate. |
| What do sea stars eat? | Mollusks, crabs, and even other echnioderm's |
| how are eggs fertilized for echnioderm's | they are fertilized right in the seawater after the female releases them and the male releases his sperm. |
| What happens if a sea star losses and arm? what is this called? | it can grow it back. This is called regeneration |
