“<b>How are crustaceans different to chelicerates?</b>”
Presence of antenae
“<b>Do barnacles (Cirripedia) spawn?<br></br></b><img></img>”
No - use BDE

Yes
“<b>Are antennae in crustceans the smaller 1st pair or the second longer pair?</b>”
2nd pair
“<b>The Green Gland pore in prawns and crabs (Decapods - Malocrustacea) is found?</b>”
On the base of the 2nd antennae
“<b>Biramous appendeges in Crustaceans have which two segments?</b>”
Exo & Endopods
“<b>Decreasing appendages & increasing specialisation is found in which Phyla?</b>”
Crustacea
“<b>Are crustaceans protosomes?</b>”
Yes
“<b>Repoduction is mostly sexual, rarely asexual, and occasionally parthenogenic - describes the traits of which Phyla?</b>”
Crustacea
“<b>Nephridia excretes NH3 ammonia over gills in which phyla?</b>”
Crustacea
“<b>What are Scaphongnaithite?</b>”
leafy gill bailers on the 2nd maxillae, organ pumps water over gills to promote gas exchange
“<b>How do small crustaceand respire vs large crustaceans?</b>”
Small ones respire across body surface, large ones respsire via feathery gills protected by a carapace
“<b>Large crustaceas use feathery gills that increase surface area which helps with?</b>”
respiration
“<b>Which phyla uses brood sacs or brood chambers on thier abdominal appendages?</b>”
crustacea
“<b>How do green glands function?</b>”
“osmoregulates body cavity fluid, filters & excretes out pore on 2nd antenna<br></br><br></br>also used for sex signaling by males”
“<b>Branchiopoda are a phyla similar to bivalves. True or false?<br></br></b><img></img>”
False - small primitive shrimp
“<b>Are nauplis segmented?</b>”
No - unsegmented
“<b>How many appendages to Naupluis have?</b>”
3 - antennae, anntenules, manidbles
“<b>Crustaceans and ____ have setae on appendages for locomotion and respiration?</b>”
Polychatae
“<b>Difference between Isopod and Amphiopod?</b>”
“Isopods are DV flattened, Amphiopods are laterally flattened”
“<b>Amphiopods are DV flattened. True or False?<br></br></b><img></img>”
false, isopods are
“<b>Isopods are laterally flattened. True or False?<br></br></b><img></img>”
False - DV flattened
“<b>What do Isopods and Amphioda have in common?</b>”
“can be parastitic<br></br>flattened but differently<br></br>sessile eyes not attached to stalk<br></br>no carapace<br></br><img></img>”
- Isopoda – no carapace, DV flattened with armour plating;
- Amphipoda – no carapace, laterally flat
- Euphausiacea – plankton
- Decapoda – crabs, lobsters, shrimp
Maxillopoda
Malacastraca
Anostraca (fairy shrimp)
Notostraca
Diplostraca (sea lice)"
Notostraca: carapace large dorsal shield
Diplostraca: carapace encloses body but not head
