Explain how an open circulatory
system works.
As noted in the picture, in
an open circulatory
system the blood vessels
are not fully connected
blood flows from the
heart to various openings
(sinuses) located in the
body where nutrients are
exchanged then pulled
back into vessels
Name the 3 body regions
the mollusc is divided into.
Head, Foot, Visceral Mass
Explain how predatory snails
feed.
Predatory snails use a radula to drill a hole through the
shell of their victim and then they insert their proboscus
with the radula at the tip and proceed to scrap the
internal tissues from the victim
How is a Cone Snail different in its
predatory skills?
Cone Snails use their modified radula dart to
harpoon their prey and insert a neurotoxin
that immobilizes the prey
What is jet propulsion?
Is jet propulsion an efficent mode of locomotion?
List 3 examples of organisms that use jet propulsion.
Jet Propulsion is when the cephalopod uses the process of
pumping water through a siphon to propel them through
the ocean.
No
Squids, Octopuses, Cuttlefishes, and Chambered
Nautiluses
How can the largest of the Cephalopods
accommodate for jet propulsion?
The largest of Cephalopods will use the
fin like structure of their mantle to help
move them through the water.
How are Nudibranchs different
from other Gastropods?
Nudibranchs lack a protective shell that many
other gastropods have.
The ability to change colors allows many
Cephalopods to do many things, name some
of those things that they are able to do.
The ability to change colors allows cephalopods to
communicate with other individuals, allows them
to camouflage with their environment, allows
them to hypnotize their prey, etc.
Explain the function of the chambers
in the chambered nautilus.
The chambers inside the shell of the chambered
nautilus allow for buoyancy. The nautilus can
regulate its density by injecting or removing fluid
into/out of these chambers through a system of
tubes.
Some of the male cuttlefish have an interesting
trick to successfully mate with the female
cuttlefish. What is this interesting trick and
why is it so successful?
Some smaller males ‘cross-dress’ to look like
females by pulling in their tentacles. This tactic is
successful because the bigger males will let the
cross-dressing male to pass by unchallenged. The
cross-dressing male can then mate successfully
with the female cuttlefish.
Explain the function of the adductor
muscles for the bivalves
The adductor muscles in a bivalve allows
them to open and close their shells quickly
What is the primary mode of locomotion
for the clam? And explain how this mode
of locomotion works.
The primary mode of locomotion for the clam
is its foot. The clam pushes the foot into a
substrate. The foot then fills with blood
causing it to expand and grip the substrate.
Then the clam pulls the body toward the foot.
Explain why it is so important that the
squid must cut down food into tiny bits.
The squid’s brain is shaped like a donut
with the esophagus running through
the middle of it. If the squid eats
something that is too large the
esophagus could stretch out put
pressure on the brain and cause brain
damage to the squid.
What happens to the cuttlefish after they
mate?
They die
What is unique about the cuttlefish’s eyes
and why is that beneficial?
The cuttlefish’s eyes are shaped like a
‘w’ which allows for better peripheral
vision.
