arthropods have this type of circulatory system
arthropods have a well developed _________
are saclike organs that extract waste from the blood and add them to the feces in arthropods
__________ type of fertilization in terrestrial arthropods
__________ type of fertilization in aquatic arthropods
process by which arthropods shed outgrown exoskeletons and manufacture larger ones to take place
molting is controlled by this system
What is the subphylum of arthropods that are primarily aquatic and typically have two pairs of antennae, 2-3 body segments, and mandibles?
this is the third pair of appendages in a crustacean anatomy that is a biting and grinding mouthparts
fusion of head and thorax, houses most of internal organs
this covers the cephalothorax
posterior part of a crustacean anatomy
this is the first two pairs of appendages in a crustacean anatomy, and it bears sensory hairs
this is attached to the cephalothorax
what is the first pair of legs in a crawfish called that bears large claws that are modified to catch, pick up, crush, and cut food?
this is located on the abdomen of crawfish and are flipperlike appendages used for swimming
How many pairs of legs does the animals of the Crustacean subgroup have? (type in the number)
how many pairs of walking legs does a crawfish have? (type in the number)
What kind of crustaceans lost their abdominal segments, don't use mandibles, and use appendages to draw food to its mouth?
What is the subphylum of Arthropods that contain spiders and their relatives such as horseshoe crabs, spiders, ticks, and scorpions?
these are specialized mouthparts that are the first pair of appendages attached near the mouthparts in chelicerates
they have two body segments - cephalothorax and abdomen-, four pairs of walking legs, lack an antennae, and respire using book lungs, where spiracles are used for air to enter into.
these are the other pairs of appendages that are longer than chelicerae and are modified to catch prey in chelicerates
this is the class of the subphylum Chelicerata that includes horseshoe crabs and are amongst the oldest living arthropods that appeared over 500 years ago.
they have a chitonous exoskeleton, and their anatomy is similar to spiders - they have chelicerae, five pairs of walking legs, and a long spikelike tail.
this is a class in the subphylum Chelicerata that includes spiders, mites, ticks, scorpions.
_________ are the largest groups of arachnids that have no jaws to chew food but liquefies food instead.
specialized pumping stomach
Spiders suck liquefied body tissure through this
Spiders inject _______ ________ into prey.
all spiders produce this even if they do not spin webs, and it is stronger than steel.
these are silk glands through which spiders force liquid silk
Another subphylum of arthropods that includes centipedes, millipedes, and insects.
arthropods with characteristics including jaws, one pair of antennae, and unbranched appendages.
this bug has leg pairs ranging from a few to more than 100. Their body segments bear one pair of legs each and they use claws to stun or catch their prey.
this is the class in the subphylum Uniramia that includes centipedes.
this bug lives underground, and their spiracles cannot close because their exoskeleton is not waterproof and they lose water easily.
This is the class in the subphylum Uniramia that includes millepedes.
they have 2 sets of legs per segment; they aren't very aggresive; they live in dark habitats, often under rocks.
This is a class that is under the subphylum Uniramia that contains more species than any group of animals. It have a three-part body with a segmented body, jointed appendages, and an exoskeleton.
_____ and _____ account for one third of the animal biomass in the Amazon Basin. (just type both words and leave a space inbetween)
insects have what kind of eyes?
insects are extremely sensitive to ____ and _____. (again type the words and leave a space between)
this insect have a tubelike mouthpart to suck nectar.
this insect has a spongelike mouthpart to lap food.
insects have ______ that can contain a digestive enzyme to break down food.
insects have __ pairs of legs. (type the number)
insects have __ pairs of chitin wings. (type the number)
a phase in the growth and development of insects that involves changing shape and form
this is an immature form very similar to an adult form
it is a stage during which a larvae becomes an adult.
these are immaturer forms of insects that undergo incomplete metamorphasis
these immature insects cannot fly because they have no reproductive capability; they undergo initial growth phase involving molting; their appearance and habits do not change in initial phase; and the final molt results in formation of a pupa.
sound visual chemical
insects use ______, _______, ______, and other types of communication. (type words leave space in between)
specific chemical messages that affect the behavior or development of other members of hte same species.
groups of closely related animals of the same species that work together for the benefit of the whole group
groups of individuals that perform a specialized role in a society
this is what bees do when they have located food at a distance.
this is a phylum that contains starfish, sea stars, sand dollars, and sea urchins
this means "spiny skin"
the name echinoderm refers to the presense of _________ formed form hardened plates of calcium carbonate; it gives echinoderms a bumpy and irregular texture.
In echinoderms, the adults have no _______ or _______ end. (type in word and leave space in between)
the adults of echinoderms lacks this process.
echinoderms have ______ symmetry
they are characterized by spiny skin, an internal skeleton, a water vascular structure, and tube feet.
they are suction-cup like structures on the ventral sides of echinoderms; they attach to each radial canal.
water vascular system
fluid-filled system of vessels that carries out essential functions such as respirationi, circulation, and movements IN ONLY ECHINODERMS!!!
the water vascular system is open to the outside through the _______, which connects to a ring canal that encircles the animal's mouth.
they use jaw-like structures to scrape algae from rocks.
they use tube feet to capture floating plankton.
they feed on mollusks by pushing their stomach through the mouth to release enzymes that digest mollusks in their shells; then pulls digested prey back into its mouth
this is where the digestive waste are realeased as feces
echinoderms do have have a _______ system due to lack of cephalization
echinoderms have a ________ ring surrounding their mouth.
echinoderms reproduce using ______ sexes
echinoderms reproduce using _________ fertilization.
sea urchins sand dollars
_____ _____ and _____ ______ have large, solid plates that form a box around their internal organs; they are detritiroves or grazers that feed on algae; they have defense through burrowing, wedging into small crevices with the use of long sharp spines. (just type the words and leave a space inbetween)
_________ _______ are common in coral reefs; they have slender, flexible arms that allow rapid movement; they use speed and ability to shed arms for protection; and they are filter feeders and detritivores.
______ __________ are tube-shaped echinoderms that move along the ocean floor; they are detritivores that suck up organic matter; they move in herds of hundreds of thousands in deep oceans.
sea stars (starfish)
_____ ______ move by creeping along ocean floor; they are carnivorous; they eat bivalves; they have excellent regenerative abilities; they are ecologically important- shift in population effects other organisms.
