Squid

What do you think of when your hear the word “squid?” Sea monsters with enough size and strength to drag down a ship? Hellish man-eating creatures of the deep? Think again. When I think of the order Teuthida, I think of medical discoveries, saving lives, fascinating intelligence, and scientific revelations. I think of complex anatomy and diverse shapes and sizes. I think of adaptability and resourcefulness. I think you should read this research paper on squids. Squids have quite an interesting appearance. The squid is bullet-shaped, partly due to the mantle, the sack that contains all of the vital organs of the squid. Every squid has 3 hearts - 2 at the gills, and 1 main heart that pumps copper-based blood. Teuthida is lacking of…

Squids and Octopi may be two of the most fascinating and unique creatures to live on the planet. With each animal having close to over two hundred different species, two that distinguish themselves from all the other species are the giant octopus and the giant squid. A misconception often made is that these two animals are the same and just have different names. While they both belong to the same class of Cephalopoda, they are in fact two completely different species both belonging to a…

Squid are said to be among the most intelligent invertebrates in the world. Their brain structure is different from other invertebrates in the ocean because they share complex features similar to the human brain. Squid are very smart and can be very curious about their environment, have the ability to learn new skills, and can develop the capacity to use tools that can either help them repress their boredom or protect themselves from harm (Squid-World Editors). Squid are thought to be among the…

Vampire Squid Very Strange Squid Species Of all the different varieties of squid, the Vampire Squid is a very strange squid species that makes its travel far below the waters nearly a half-mile down near the bottom of the ocean. Even though by its name you would think it sucks blood, the vampire squid actually just eats zooplankton, and is actually part of the animals in the Cephalopoda Class (animaldiversity.org/accounts/Cephalopoda), which means it has a lot in common with some of the oldest…

The vampire squid is an interesting creature to say the least. It is a deep sea dweller and is a close relative of squid and octopi, making it almost its own species. This creature is an important part of many deep sea ecosystems found around and inside the Pacific Ocean. The vampire squid or by its scientific name (vampyroteuthis infernalis) is a part of the cephalopod family. This creature was mistakenly found and named an octopus when first sighted. The visual appearance of this marvel is…

reason that many believed that the giant squid was a passive hunter was the amount of ammonium in its tissues. There are two groups of squid in relation to density in water; the first are denser than water and must swim to stay afloat, the second are “nearly neutrally buoyant” (Clarke et al. 1979). The giant squid falls into the second category; it remains buoyant because of ammonium chloride filled pockets in its muscles, which balance its density. This means that it does not need to be active…

Have you ever wondered what the difference is between an octopus and a squid? While they are similar in many ways, they are also different in others. I will talk about both the similarities and the differences between their physical characteristics, their habitat, and their behavior. The octopus and the squid are both similar and different in the way they look. They’re closely related to mollusks. Squids have a backbone-like structure that is flexible which is similar to the shell of a snail.…

These trees also exhibit the misleading name of vampire squid which are in fact not true squid and are generally more related to octopuses (Yokobori et al., 2007). There is a current interest in squids because of their large geographical range and the increase in biomass of the Humboldt and Jumbo in the Pacific Ocean (Young et al., 2013). Squids appear to be on their way to becoming much more significant in their respective ecosystems and would be well worth studying. Squid also come in sizes as…

The Colossal squid or its scientific name, Mesoychoteuthis Hamiltoni, is the largest of the squid species so far known to man. The colossal squid gets its name because of how large it is. In ancient times, scientists believe fishermen saw them or their cousins, the giant squid. In fact, scientists also believed that the ancient myths like the Scylla in the Ancient Greece myths and the Kraken in Norwegian legends were actually colossal or giant squids that the sailors saw. They appeared to be…

Cuttlefish are extremely intelligent animals with very small brains. There ways of survival have worked for them for countless years. Cuttlefish are mollusks are invertebrate of a large phylum that includes snails, slugs, mussels, and octopuses. They have a soft, unsegmented body and live in aquatic or damp habitats, and most kinds have an external calcareous shell. Cuttlefish are expectedly cousins with squids and octopuses. Cuttlefish release ink when they want to retreat or evade a common…
