1chromatophores
“freckles” allow the squid to chabge colors
2fins
help squid change direction when swimming
3mantle
main part of the sauids body-all organs are inside
4pen
all that is left of the shell the squids ancestors once had
5eyes
on the side, giving them more peripheral vision, which is great for hunting
6tentacles
longer than the other 8 arms and have suction cups only at the tips. they are used to the shorter arms and then to the mouth
7arms
arms have suctions all the way down. they help the squid to hold onto food
8buccal bulb
attaches to the esophagus, which is attached to the stomach.
9beak
hard and is a dark brownish color
10collar
on the opening of the mantle
11siphon
water is pulled into the mantle. mantle is squeezed forcing water out through the siphon. this type of movement is called jet propulsion.
12gills
are feathery structures that absorb oxygen from the water. increases the amount of the surface area potential for gas exchange.
13inc sac
lies on top of the liver. squid released ink from gland in times of danger, which is then pushed through the siphon.
14heart
squid have 3 hearts-2 branchial and one systemic. the hearts are located at the bottom of the gills. the heart is for blood circulation
15gonads
this is the reproductive organ. in males, it is s white-ish mound (sperm sac). in fenaled it is clear to yellow/orange mass of eggs.
19what is the latin meaning of phylum and class?
soft body and head foot
20how do squid protect themselves from predators?
by use of camoflauge and squirting ink
21what happens when you rub the chromatophores?
they change size and color
22where does squid fit into the marine food web?
secondary anf tertiary consumers
23what role does the squid play in the ocean ecosystem?
transport carbon and nutrients between marine ecosystems
24what adaptations does the squid have that allow it to play that role?
they have s siphon that provides jet propulsion and fins
