Mollusks
Mollusks exhibit this type of symmetry.
What is bilateral symmetry?
This arthropod class includes animals like crabs, lobsters, & shrimp.
What are crustaceans (class crustacea)?
Echinoderms typically exhibit this type of symmetry.
What is radial symmetry?
This is the primary habitat for invertebrate chordates.
What are marine environments?
This is the primary function of an arthropod's exoskeleton.
What is to protect and support the body?
Snails and slugs are in this class.
What are gastropods (class gastropoda)?
Arthropods are defined by these characteristics (list 2).
What is a Segmented Body, Exoskeleton, & Jointed Appendages?
The process some echinoderms go through to repair damaged or lost limbs.
What is regeneration?
Invertebrate chordates lack this characteristic that is found in vertebrate chordates.
What is a backbone?
This arthropod group includes animals with numerous body segments, such as centipedes and millipedes.
What is the myriapoda class?
This type of mollusk uses jet propulsion to move.
What is an octopus?
The process by which arthropods shed their exoskeleton as they grow.
What is molting?
This structure helps echinoderms move and eat.
What are tube feet?
This characteristic is common of all chordates, including invertebrate chordates.
What is a notochord?
These are the two invertebrate chordates we've discussed in class.
What are lancelets and tunicates?
This structure helps many mollusks scrape food.
What is a radula?
This group of arthropods have two main body segments, the cephalothorax & the abdomen.
What are arachnids?
This feature is unique to echinoderms; a unique network of fluid-filled canals that allows them to move, capture food, and perform other functions.
What is a water vascular system?
This structure is used for filtering food.
What are pharyngeal slits?
This group of mollusks have a closed circulatory system.
What are cephalopods?
A mollusk shell is primarily made up of this mineral.
What is calcium carbonate?
This structure is what most insects use for breathing.
What are tracheal tubes?
This echinoderm can eject part of its internal organs as a defense mechanism.
What is a sea cucumber?
This characteristic is common to all chordates, including invertebrate chordates, at some stage of their life cycle.
What is a dorsal hollow nerve cord?
This class of echinoderms is characterized by a long, flexible arm structure that resembles a brittle star.
What is class ophiuroidea?
