Ecdosozoa Flashcards
ECDOSOZOA
What are ecdosozoa?,
Molting protostomes. They have a cuticle.
What are the phylum of Ecdosozoa?
Nematoda, Nematomorpha, Anthropoda, and Cycliophora
Phyla Nematoda
They are very duverse on terms of habitat. They are parasitic mostly, they have longitudinal muscles and are morphologically simple. Ex) vinegareels
What is the base model nematode?
C. elegans
Why is C. elegans good?
It has good developmental biology mapping and is simple
What are vinegareels? (Nematoda)
They are not really eels, they feed on yeast ad bacteria that causes fermentation.
What are pinworms? (Nematoda
They live in the large intestine and give you itchy anus
What are Trichina worms (nematoda)
Parasytic worms that are in undercooked pork.
What is Ascaris lumbricoides
Most prevelant nuotode and can cause health issues
What is hookworm (nematoda)
It has an appendage to latch on to host
What are Filarial worms (nematoda)
They are worms that cause filarasis which causes heartworm
What is Dracunculus medinensis (nematoda)
Burrows into muscle
Phylum Nematomorpha
These are horsehair worms that are parasytic when young, but not when older. They have a vestigal digestive tract.
Phylum Arthopoda
Largest and most diverse found.
What is the economic cons of arthopoda?
Parasites, disease, pests, agriculture, and domestic pets.
What are the economic pros of arthopoda?
Food, pollination, honey, wax, silk, dyes, and drugs.
What are some general characteristics of arthopoda?
Protostome eucoelomates (hae a true organ system), metameric (arranged in parts), tagmosis (body arrangement), jointed appendages, molting, complex muscles (smooth and striated)
What is the circulatory system in arthopoda?
Heart, arteries, hemocoel, open circulatory
Nervous system in arthopoda?
Antennae, eyes (ocellus and compound eyes)
Respiration system in arthopods
cutaneous, gills, book gills, book lungs, tracheal
Reproduction in arthopoda
They are dioecious
Subphylum trilobita
Extinct. 3 lobed abdomen. Branched appendages
Tagmata of trilobita
Head -> thorax -> abdomen
Subphylum Chelicenata
They have somewhat pincerlike mouth parts (chelate). 2 body regions
Arthropoda classes
Meristomata, pychogonida., arachnida
Meristomata
Living fossils. Horseshoe crabs. Simple oculi and compound eyes, book gills, mouth parts (chelicerae are pincher like as well as their legs. They have a telson or tail.
Class pychogonida
Sea spiders. Marine, have 8 legs. reduced bodies. Organs in legs. Males carry eggs on modified legs
Class arachnida
Diverse. Spider, scorpion, mites, ticks, daddy longlegs. Most are predators, some have venom
Spider order
Araneae
Scorpion order
Scorpiones
Mite order
Acavi
Daddy longlegs order
Opiliones
Subphylym Crustacea
They are also diverse, monophyletic takon.Marine. Branched appendages, jaw like mouth parts (mandibles) Tagmosis is cephalothorax and abdomen.
How many antennae do crustacea have?
2 pairs
Order maxillopoda
is ostracods, copepods, and barnacles
Order malacastracta
Isopods, krill, everything we eat
Subphylum Uniramia
Have uniraous appendages and single pair of antennae
Class Cholopoda
Centipedes have 1 pair of legs / segment. Tagmosis: head and trunk. Predators with venomous claws.
Class Diplopoda
Milipedes. Have 2 pairs of legs / diplosegment. Their glands have cyanide
Class insecta
Insects. Tagmosis: head, thorax, abdomen. Thorax is where locomotive structures are located. 2 pairs of wings and 3 pairs of legs
What are the 3 categories for insects?
Ametabulous, hemimetabulous, and holometabolist
Ametabulous
look the same smaller and big Ex) silverfish
Hemimetabulous
Egg -> nympj -> adult. Typically have wings. Ex) grasshopper
Holometabolist
Egg -> larva -> pupa -> adult Ex) beetle and butterfly
What are the 7 biggest orders of insects?
Odonata, orthroptera, nemiptera, coleoptera, diptera, hymnenoptera, lepidoptera.
Odonata
dragonflies and damselflies
Orthroptera
Straightwing. Grasshopper, cricket, ect
Nemiptera
True bugs with x pattern
Coleoptera
Beetles, shieldwing
Diptera
ones with 2 wings. Flies
Hymenoptera
Bees, wasps, ants. Have social behavior
Lepidoptera
Butterflies and moths
Phylum Cycliophora
Hidden. Live in hair on mouthpart of lobster.
