The function of suction cup of squid?
As far as I know, they're used for self-defense and to hold onto food while they're eating it. The suction cups are lined with razor sharp "teeth" which can leave pretty nasty scars on a while looking for a squid snack. I hope this helps you! :D
What would a squid be classified as?

How many giant squid do sperm whale eat a day?
Sperm Whales are carnivores and feed on several species. The most notable prey species are the giant squid, the colossal squid, octopuses, and diverse fish like demersal rays, but the main part of their diet consists of medium-sized squid. Due to their sheer size, some prey may be taken incidentally while eating other items.
Does a baby squid come out alive or in a egg?
Squids lay about 200.000 eggs each time.
This depends on the specimen though.
Where does the jet of water come from a giant squid?
The squid sucks up water a tube called the siphon, then shoots it out to provide locomotion by jet propulsion.
Is a squid a tertiary connsumer?
Yes,because little fish eat plants at the bottom of the ocean,where giant sqiud live.
Does the giant squid have the largest eyes in the world?
No - squids and reptiles belong in completely different groups of the animal kingdom.
Squid, cuttlefish, and octopus belong to a phylum called cephalopod mollusks.
What does cephalization refer to?
Cephalization refers to the gathering of neural tissue towards the anterior or posterior for means of central control. In arthropods, cephalization has formed the brain in the head of the animal, usually consisting of the first three ganglia of the paired nerve cords.
What is the difference between a male squid and a female squid?
The difference between a male and female sponge is that the female lays the eggs the male doesn't the male helps with different things
What does an eye of a squid look like?
They look like big eyes that are the size of footballs. The puples and color on some squids are black. But all squids have whites.
-- If it is a Giant Squid, they eyes can be the size of basketballs, but squid in general are small. Their eyes are generally large compared to body size and are round. They have a single black dot in the middle, like the human pupil, which is surrounded by chromatophores which can change colour like the squid's skin, not whites. --
How big is a giant squid's eye?
What animal group is a squid in?
Is another name for an octopus cuttlefish?
The other name for the octopus is not cuttlefish, it is devil fish.
How many squids are there on earth?
Actually the colossal squid hasn't been proved an actual species yet so its hard to say how many, sorry.
Why does the squid have that black spot in their bodies?
Not sure what squid, or what black spots you are talking about. Many squids, like many cephalopods, have the ability to change colors depending on their mood, or environment. Some even being able to change colors on on half of their body versus the other when "speaking"/reacting to others of their species. They can even make fake eyes at the other end of their bodies to intimidate and confuse predators. They do this because they have evolved cells called chromatophores, which can change colors as well as reflect light, some are photosynthetic as well due to the bacteria that are found in the cells.
The vampire squid (which is not a real squid) has primitive versions of these cells, which are only black. Not sure if this is the squid and the black spots you are talking about
Different types of squid eat different types of fish. Small squid, a few feet in length, eat small fish. The giant squid, about twenty feet in length (or more), eat bigger fish, even a shark on occasion. It depends on the size of the squid on how big their prey is.
How many legs does a female octopus have?
A female octopus will only mate once. A female will mate with (obviously) a male, she will then lay her eggs in a den. She will not leave the den until the eggs have hatch. By the time the eggs hatch, the female will have died of starvation.
