Octopuses, or octopi, are predators. They hunt crabs, prawn, fish, and mollusks. However, in turn they are also hunted by sharks, dolphins, and other sea animals, so they are also prey. This means that they are not top predators, but somewhere in between.
There is no single kraken. The name refers to any large squid or perhaps even octopus.
The sea monster Cetus killed by Perseus (who used the gorgon head of Medusa to turn it to stone) was not a kraken but a large serpentine fish.
How does the octopus defecate?
Like all cephalopods, squid have complex digestive systems. The muscular stomach is found roughly in the midpoint of the visceral mass. From there, the bolus moves into the caecum for digestion. The caecum, a long, white organ, is found next to the ovary or testis. In mature squid, more priority is given to reproduction such that the stomach and caecum often shrivel up during the later life stages. Finally, food goes to the liver(or digestive gland), found at the siphon end, for absorption. Solid waste is passed out of the rectum. Beside the rectum is the ink sac, which allows a squid to rapidly discharge black ink into the mantle cavity.
What is the size of a fully grown cuttlefish?
a cuttlefish is the size of your large thumb put together twice.
No. Amphibians are animals like toads, frogs, salamanders, mudpuppies, etc., that metamorphose from a juvenile waterbreathing form (e.g. tadpole) to an airbreathing adult form. They're usually four-limbed vertebrates, and superficially similar to reptiles.
Octopuses are invertebrates par excellence, most of them with no vestige of a skeleton, and also with radial symmetry, not bilateral symmetry. They have no spinal cord; each arm has a complex "nerve cord" and is capable of complex semi-autonomous behavior, hence the "nine brains" meme. Octopuses can live outside the water for at least a few minutes, for example to get out of their tank and into your tropical fish tank to eat the fish, but they can't actually live on land.
How much weight for a baby octopus?
It Varies from species The Blue Ringed OCtopus weighs less than 90 on average.
What it the taxonomy of the common octopus?
Kingdom Animalia Phyllum Mollusca Class Cephalopoda Order Octopoda Family Octopodidae Genus Octopus Species vulgaris
It wasn't really the Kraken, it was called The Watcher in the Water. You can learn a little more about it in the appendices of The Return of the King (book).
The stregnth of a Kraken is unknown, because it is a mythilogical creature. There is no way to measure the stregnth of a unreal character. In the Pirates of the Caribbean Movies, it is stong enough to crush one ship at a time.
Yes, it is a mollusk because mollusks are squid or octopus-like creatures. Mollusks have a variety of ways to create a shell. Some mollusks have shells on the outside, such as a variety of gastropods. The Nautilus is one of the first cephalopods, which traditionally do not have an exoskeleton shell, which does have an outer shell covering.
No, cuttlefish are not crustaceans. They are a type of marine mollusk, related to squids and octopuses. Crustaceans are a separate group of arthropods that include animals like crabs, lobsters, and shrimp.
What is the function of the squid's internal shell?
I was looking for the answer and I did and now I am deciding to share what I found. (\^_^)/)
1. Siphon - small tube on the ventral side of a squid/octopus
that can be directed in any direction for jet propulsion
locomotion.
2. Eye - sensory equipment on the head of the squid which
rivals the complexity of mammalian eyes.
3. Mantle - soft skin covered organ of the squid that covers the
body in place of the normal molluskan shell.
4. Tentacle - soft unsegmented appendage of a squid used for
grasping prey or reproduction.
5. Sucker - small suction device on the surface of a tentacle
used for holding prey or mates.
6. Pen - small and stiff support structure within the mantle used
for mantle support.
7. Nidamental gland - secretes the gelatinous matrix that
surrounds the squid eggs.
8. Ovary - produces eggs.
9. Buccal area - the mouth area of the squid, including the oral
cavity and radula.
10. Radula - the scraping organ of feeding in mollusks,
structured as a bird's beak in squid and octopi.
11. Esophagus - tube that passes food from the mouth to the
stomach.
12. Stomach - digests food polymers into smaller polymers and
monomers.
13. Caecum - receives food from the stomach and absorbs it to
the bloodstream.
14. Intestine - receives food from the caecum and continues to
absorb nutrients to the blood.
15. Rectum - receives food from the intestine to pass it to the
anus and out of the body.
16. Liver - produces digestive fluids for the digestion of food.
17. Systemic heart - receives blood from the gill hearts and
pumps it to the body of the squid.
18. Gill (brachial) heart - pumps blood to the gills of the squid.
19. Nephridium - the excretory organ of the squid, filtering the
blood of waste products.
20. Gill - respiratory organ of the squid, exchanging oxygen and
carbon dioxide between the blood and sea water.
21. Ink sac - organ that stores a black substance that serves to
deceive potential predators and allow escape
22. Fin - extension of mantle used to guide and steer during
swimming.
No. Squids eat other marine animals; therefore being a carnivore.
How many teeth does the kraken have?
As the kraken is a legendary creature out of lore, it can be argued that no one knows, as no one has studied it.
What is the deadliest part of a squid?
The squid as a predator has a sharp, beak-like bill, and there are serrated edges on the suction rings of the tentacles.
Only a giant squid is dangerous to humans.
Where does one buy Nautilus fitness equipment?
Nautilus fitness equipment is available for purchase directly from the Nautilus company on their website. It can also be purchased second hand on auction sites. One could even purchase used Nautilus fitness equipment at yard sales and from classified ads.
