Verified Q&A for Success
Oviparous - ✔✔species that deposit fertilized eggs and the embryos are nourished by the yolk
Ovoviviparous - ✔✔species that retain eggs inside their body during early development but the growing
embryos are nourished by yolk inside the eggs and give birth to well-developed young.
Mollusk - ✔✔-foot-large muscle located at base of animal used for movement.
-visceral mass-region containing most of the main internal organs and external gill
-mantle-outgrowth of the body wall that covers the visceral mass.
foot of protostomes - ✔✔works as a type of hydrostatic skeleton
mantle of protostomes - ✔✔secretes a shell made of calcium carbonate to protect the organism
visceral mass of protostomes - ✔✔separates the internal organs from the hydrostatic skeleton
Arthropod - ✔✔have bilateral symmetry, a segmented body(head,thorax, and abdomen), an
exoskeleton and jointed appendages(allow movement)
hemimetabolous metamorphosis - ✔✔juveniles look identical to adults
holometabolous metamorphosis - ✔✔distinct difference between juveniles and adults.
,Deuterostomes - ✔✔include the largest bodied and some of the most morphologically complex of all
animals
Echinoderm - ✔✔exclusively marine deuterostome organisms that contain a five sided radial symmetry,
a endoskeleton and a water vascular system
endoskeleton - ✔✔a hard structure located just inside a thin layer of epidermal tissue which provides
protection and support
water vascular system - ✔✔a series of branching, fluid-filled tubes and chambers that is open to the
exterior so seawater can flow into and out of the system.
tube feet - ✔✔clamp onto a shell with their feet and prying it open to feed on clams and mussels. also
use suspension feeding.
chordate - ✔✔contain pharyngeal gill slits(gas exchange), a dorsal hollow nerve cord, a notochord and a
post-anal tail.
Dorsal hollow nerve cord - ✔✔a bundle of nerve cords that runs form the brain to the posterior of the
body
Cephalochordates - ✔✔small mobile torpedo shaped animals that use suspension feeding
Coelom - ✔✔a fluid-filled cavity between the inner and outer tubes in a tube-within-a-tube body shape.
can act as an efficient hydrostatic skeleton to help them move effectively.
Coelomates - ✔✔bilatarians that possess a coelom that is completely lined in mesoderm
Acoelomates - ✔✔bilatarians that subsequently lost their coelom
Pseudocoelomates - ✔✔bilatarians that retained a coelom but lost the mesodermal lining in parts of
their coelom
, Protostomes - ✔✔the mouth develops before the anus and blocks of mesoderm hollow out to form the
coelom
Deuterostomes - ✔✔the anus develops before the mouth and pocket of mesoderm pinch off to form
the coelom.
Segmentation - ✔✔the presence of repeating body structures
vertebrates - ✔✔includes fish, reptiles, birds, amphibians and mammals. Contain a vertebrate and a
cranium.
Sensory Organs - ✔✔magnetic field(navigation), electrical field(detect muscle movement) and
barometric pressure(avoid storms)
Suspension feeders(filter feeders) - ✔✔organisms that trap suspended particles to feed
Deposit feeders - ✔✔digest organic matter in sediment(similar in appearance)
Viviparous - ✔✔live-bearing species that nourish embryos inside their bodies and give birth to live
young
Urochordates - ✔✔tunicates or sea squirts have a larger gill slit for feeding and oxygen exchange
forebrain - ✔✔part of the brain responsible for sense of smell
midbrain - ✔✔part of the brain associated with vision
hindbrain - ✔✔part of the brain responsible for balance and hearing
