Ocean

We are all familiar with dolphins, whales and sharks; we know what tuna and snapper look like, but what about some less familiar fish such as lizardfish, giant squid, or blind eels? There are so many lesser known animals in the depths of the ocean that we hear little or nothing about most times, it is interesting to investigate a few of these creatures and understand them a little more.

The first on our list of deep sea creatures is the fangtooth fish. This fish is one of the most evil looking ocean predators. It lives in the deep ocean and catches its prey by luring them in with glowing light organs called photophores. In such a dark abyss, fish are attracted to the light put off by the organ and once they are close enough the fangtooth fish catches them in his numerous large teeth. He looks like an underwater vampire.

Another carnivorous sea animal is the deep-sea lizardfish. These interesting fish look almost like a short snake in water. Their mouths are covered with harpoon-tipped teeth that grasp their prey and don’t let go, similar to a fish hook. These teeth are hinged so that they can flattened down when prey is going in and stand up when resisting. They don’t even need to actively swallow; the struggling prey just ratchets itself inside. With their glowing yellow eyes, the lizardfish is a wonder to behold.

Often called the nastiest fish in the ocean, the blind eel is next on our list. These fish are called blind eels because they have such small, ineffective eyes. Who needs eyes when you are living in almost complete darkness? They prey on live or dead fish which they locate through smell. They have circular mouths that they use to suck on their prey. They have tooth-studded tongues that allow them to cut through their victims flesh and literally eat them from the inside out. They are also sometimes called slime eels because their skin emits a sticky slime, up to a gallon at a time. It is used to suffocate predators by clogging their gills when they attempt to eat the eel.

The last of our unusual deep sea animals, giant squid, has been the subject of tall tales for centuries. Until recently, however, these tales were dismissed as fiction. The only information we have on them comes from finding pieces of their bodies in the stomachs of sperm whales, or those that have been washed up on shore. Another area where their existence is apparent is on the skin of sperm whales where giant sucker scars can be seen after what must be epic battles between the two huge creatures. Giant squid can grow to the size of a school bus or bigger. They are carnivorous and have a long, torpedo shaped body. At one end, surrounding a beak-like mouth strong enough to cut through steel cable, are five pairs of arms. One pair, thinner and longer than the rest, is used to catch food and bring it to the mouth. Just past the mouth are the eyes, eyes that are the largest in the animal kingdom, getting as big as eighteen inches across. They are nearly impossible to photograph alive because they live in such deep waters.

It is interesting to think about what other types of deep sea animals exist that we haven’t yet discovered. What wonders does the bottom of the ocean hold and can we ever know? With modern technology constantly searching for new ways to study the ocean floor, the possibility of finding new creatures becomes more real every day. For a world who thinks they have seen it all, the deep, deep ocean still holds the hope for something new.

Of all the interesting and odd creatures in the oceans, nothing is as amazing as the octopus. Here is a quick guide to this interesting creature to wrap yourself around.

A Quick Guide to the Octopus

The octopus is a mollusk. It belongs to the same group as chitons, abalone, snails, limpets, scallops, oysters, clams and mussels. The octopus also belongs to a sub-species of mollusks called the cephalopods. This means head to foot and is used as the name because an octopus’ “feet” are attached to its head.

Octopuses tend to be small in warm tropical waters and larger in colder waters. Octopi live in all the oceans, but are strictly salt water creatures. The Giant Pacific Octopus lives in the coastal waters of British Columbia and is the largest octopus in the world. The largest Giant Pacific Octopus ever caught weighed about 600 pounds, about the same weight as a Brown bear! The tentacles on the beast spanned upwards of 33 feet in length. Obviously, octopi are generally much smaller. For example, females rarely exceed 55 pounds and males average less than 90. The Giant Pacific Octopus is one of the longer lived species whereas most octopi live only one or two years. The male can live to approximately 4 years and the female can live to about 3.5 years.

An octopus has eight arms attached to its head around the mouth. These “arms” have rows of suckers along their length. They are covered with suckers on the surface and many nerves within, which means they are used to both grab and “taste” things. As an example, the Giant Pacific Octopus has two rows of suckers per arm with 1,600 suckers in all.

One of the more amazing things about an octopus is that it has absolutely no bones. The only stiff anatomical structure is the beak around the mouth, which is made of material similar to your fingernails. By the way, octopi bites are poisonous to their prey.

The octopus has an excellent eyesight and well-developed brain. It can instantly change the color and texture of its skin to match the surrounding area. This camouflage is a major method of protection.

The body of the octopus looks like a bag. It moves as the octopus breathes. Inside the mantle (the body) there are 3 hearts, the stomach and other organs. One heart pumps blood through each gill at the end of each of the two appendages while the third pumps blood through the body. Water flows over the gills and fills the mantle when the octopus breathes in. The water is forced out a tube call the siphon as the octopus breathes out. It can force water through the siphon rapidly and jet itself backwards if the octopus is trying to escape a predator. Using jet propulsion, octopi travel many kilometers. An octopus can protect itself temporarily blinding an attacker by squirting ink at it.
