Blobfish

I’m sure you’ve at least heard of the elusive blobfish. The name itself gives you a great idea of what this creature looks like: a blob of goop. The scientists in charge of naming it were clearly not thinking outside of the box. While many of the creatures covered on this list were enormous, terrifying, and dangerous, this specimen is none of the above. Allow me to introduce you to the blobfish: the world’s ugliest fish.

In Defense of the Blobfish: Why the 'World's Ugliest Animal' Isn't as Ugly  as You Think It Is | Smart News| Smithsonian Magazine

The blobfish is most famous for its hilarious appearance. It looks like a big, sad, droopy, squishy face. It looks like if Mitch McConnell was put in a vacuum chamber. The blobfish went viral on social media and was featured in countless memes due to its comical appearance. But is there more to this fish other than its looks?

There is actually a reason why the blobfish is so gelatinous and saggy. The blobfish resides at depths between 2000 and 4000 feet deep, where the pressure is much higher than on the surface. The creature’s bodily make-up is a result of thousands of years of evolving to survive the harsh conditions of the deep ocean.

The blobfish does not have bones, teeth, or much muscle mass. The crushing pressure of the ocean gives the fish enough support to not need bones. It is not a particularly active creature—spending most of its days looming above the ocean floor. Therefore, it does not need muscle.

Instead, the fish is composed mostly of water-filled cells. This jelly-like tissue is less dense than water, allowing it to stay buoyant. Because it can float effortlessly, it can conserve energy in its habitat, which is scarce in food.

Who knew this ugly fish was actually an astounding example of evolutionary adaptation? When it is in its natural habitat, it even looks pretty normal.

Blobfish, facts and information

The blobfish is just as harmless and adorable as it looks. It is not a predator in its ecosystem, so it does not hunt other animals. Who could have ever guessed a creature so ferocious and beastly was so passive?

Down in the deep, there is very little light. Therefore it does not actively look for food. It generally eats whatever happens to float in front of its face. Crustaceans, mollusks, and sea urchins make up a majority of its diet.

You might be wondering, “Why don’t we eat blobfish?” First of all, they live so deep in the ocean, it would be ridiculous to do the work to catch one just to eat it. The second reason is more somber.

The blobfish is an endangered species. It is estimated that only 420 blobfish remain in the world. This is because even though these fish lay thousands of eggs, only a few survive to adulthood. Additionally, overfishing and deep-sea trawling have resulted in the decline of their population.

As funny as it is to make memes with the blobfish’s goofy-looking face, these creatures could disappear off of the Earth forever if we do not start taking conservation efforts seriously. As a collective, we could work together to protect our oceans and the many unique creatures that inhabit it.

Portuguese Man O’ War

Beauty is pain: a famous saying that wonderfully describes the next specimen on this list. I’m sure you have seen or at least heard of the Portuguese man o’ war. With its vibrant coloring and strangely long tentacles, it is certainly hard to miss. This creature (not actually a creature which I will soon elaborate on) is greatly misunderstood. Let’s dive into it.

Portuguese Man-of-War | National Geographic

Calling the Portuguese man o’ war a creature would be misleading, for it is actually a colonial organism, which means it is composed of numerous individual organisms with different functions. The man o’ war consists of as many as seven of these organisms, called zooids, that all depend on each other.

One zooid is the gas-filled sac that keeps it afloat at the surface of the water.  Another zooid is the tentacles that help the man o’ war hunt for prey. The other zooids aid in digestion and reproduction.

Although the man o’ war is widely believed to be a type of jellyfish due to its appearance, it is not. It instead belongs to the Hydrozoa family, which are small, predatory animals that live in salt water and are often colonial.

Have you ever been stung by a jellyfish before? Depending on the type of jellyfish, it probably caused a few hours of pain and irritation, but was overall not unbearable and mainly just annoying. A man o’ war’s sting, on the other hand, is described as unbearable.

If you are stung by a Portuguese man o’ war, you will immediately feel an intense burning pain on your body. The tentacles will leave stringy, red welts on the skin that can last hours. You can also develop a rash that can last for up to six weeks after the sting.

Additionally, like some jellyfish, the man o’ war can still sting you after it dies and washes to shore. Although its sting is rarely lethal, you will definitely never forget the feeling of being stung by this lovely colony. Do not be tricked by its dazzling appearance. The man o’ war is a rose, and the tentacles are its razor-sharp thorns.

Can you believe this militia of a marine specimen also has predators? There’s always a bigger fish, I guess.

The blanket octopus is one of man o’ war’s predators. Sometimes these octopi will attach the tentacles of defeated man o’ wars to its suckers, using it as a weapon against their prey and a defensive mechanism against their predators. If you can’t beat ’em, join ’em.

The loggerhead turtle is another one of the man o’ war’s predators. Turtles have very thick skin and tongues, rendering them immune to stings. However, because plastic bags look so similar to the flotation zooid on the man o’ war, turtles will often get confused and try to eat plastic bags floating on the ocean’s surface. The man o’ war arguably benefits from plastic pollution in the ocean? That’s a first.

The Portuguese Man o' War Predator/Prey Interactions

With its unique characteristic of being a colony, its brutal sting, and its unexpected vulnerability, the man o’ war is quite the alluring and mysterious inhabitant of the ocean. Through protecting its ecosystem and admiring from a distance, we can peacefully coexist with this fascinating being and continue to observe its interesting behaviors. So, next time you come across a Portuguese man o’ war, bask in its beautiful colors, and for the love of God, do not touch it.

Anglerfish

Have you ever wondered what the terrifying fish in Finding Nemo is, or if it even exists? Well, I’m here to tell you that it indeed exists, and its arguably even stranger than you would imagine. Today we will dive into this odd and terrifying creature, and how it accommodates to the desolate, dark environment of the deep sea.

Anglerfish | Shape of Life

The anglerfish is characterized by its glowing appendage that hangs over its head, dangling near the entrance of its mouth. It utilizes its bioluminescence to lure its prey into its terrifying gape. The anglerfish is the lightbulb of the ocean, while its prey are mosquitos.

Its light source is produced by symbiotic bacteria within the anglerfish’s attractive appendage. The anglerfish waits for smaller fish to swim to its mesmerizing light, then chomps down on its meal. Because food is so scarce in the deep ocean, the anglerfish must conserve its energy to survive. This unique lure allows the specimen to do so.

The Unusual Life of the Glowing Deep Sea Fisherman – The Evolution of Planet Earth

Matriarchal societies within different species is so fascinating because it is a total twist from the standard human patriarchy. The roles that the two sexes of anglerfish play are completely different from one another. In their world, females are far larger than the males. Females have a body length of about 73 cm, whereas the males are about 49 cm on average.

When a male encounters a female anglerfish, it fuses itself to her body for the rest of its life. This allows the male to permanently give its sperm to the female, so the female always has a mating partner. They are the parasites of the sexes, but even then, the female is the one that is taking from the male. Anglerfish certainly take romantic attachment to a whole new level.

You might be asking yourself, “Why do certain species have such wildly different processes of reproduction than we do?” Animals that reside in far different environments must adapt to continue to survive and thrive. Anglerfish are just one example of evolution’s creativity and variation.

Anglerfish, Taking Romantic Attachment to a Whole New Level

Upon learning about the elusive anglerfish, I wondered why I have never seen one in the wild or in an attraction. Turns out, it is because these animals reside in one of the most extreme environments on Earth. They live in the deep sea, up to 3,000 meters below the surface. At this extraordinary depth, it is pitch black. No sunlight can penetrate the amount of water that shields them from the surface. It is also extremely cold: about 39 degrees Fahrenheit.

Finding one of these mysterious creatures unintentionally is like finding an extraterrestrial creature in your backyard. It’s just not going to happen. Whether that is a good or bad thing is entirely your opinion. Personally, I am very grateful for the miles of ocean separating us from these critters.

So far we have talked about the anglerfish’s bioluminescent lure, its unique dimorphism, and its extreme habitat. Unfortunately, there is another characterization of this animal that is worthy of being brought up: its endangerment. The population of anglerfish is steadily declining, and one species of anglerfish is considered critically endangered by the World Conservation Union.

These fish are threatened due to global warming, deep-sea fishing practices, and habitat destruction. As humans alter the environment, anglerfish are not able to thrive in the conditions in which they are designed. Conservation efforts, such as establishing marine protected areas and sustainable fishing practices, are necessary in preserving these unique creatures.

Japanese Spider Crab

A common theme in this blog is that the deeper the water, the stranger and spookier the specimens. Today we will dive (pun intended) into, in my personal opinion, one of the scariest looking creatures on this list. The Japanese spider crab will certainly pinch you back into reality as to how uncanny nature’s creations can be.

Japanese spider crab - Wikipedia

To say this crab is large is quite the understatement. When stretched out, it is 12 feet long from claw-to-claw, and 18 feet long from leg-to-leg. To put that into perspective, this crab is about as long as the width of a double-car driveway. Japanese spider crabs display a trait called deep sea gigantism, which is explains why creatures that live in deeper waters tend to be monstrously huge.

Giant Japanese Spider Crabs Can Grow Bigger Than People

Surprisingly, Japanese spider crabs are commonly found around the coast of Japan. However, they can be found anywhere in the depths of the Pacific Ocean. They tend to occupy the cold, dark waters from about 300-2,000 feet deep. As most of the creatures on this list, you will likely not come into contact with one by accident.

Giant Japanese Spider CRAB - WorldÕs largest arthropod (Macrocheira kaempferi

Although you might expect these beasts to feast upon the souls of the unfortunate, their diet includes dead fish, invertebrates, and algae. They scour the bottom of the ocean floor to find small creatures to eat. They are known to use their claws to tear open the shells of mollusks and feast upon their innards. I will spare you of an image of this event, as it looks like it could be a scene out of John Carpenter’s The Thing.

Japanese spider crabs molt to grow. Molting is a process that most arthropods perform. They shed their old exoskeletons and emerge with a new, softer one that allows them to grow larger. You might be wondering, “Where do their exoskeletons go after they shed them?” Well, these absolutely horrifying skin suits are simply left on the ocean floor until they eventually decompose. They keep pretty well, so I suppose you could keep one as a souvenir… if that’s what floats your boat.

Japanese spider crabs are not currently categorized as an endangered species. However, their numbers are steadily dwindling. This is as a result of overfishing and habitat destruction. Although their meat is usually not sought after, they often accidentally are caught in fishing nets and die. Habitat loss occurs due to pollution, mining, and a multitude of other factors that degrade the environment enough to the point where the life that resides there can no longer be sustained.

Japan has made conservation efforts to protect these crabs from going extinct. They banned fishing for them during their mating system in efforts to increase their population.

With all of the Japanese spider crab’s unique traits and behaviors, they are rendered as one of the most interesting beings this earth has to offer. Although the sea creatures featured on this list are scary and unappealing to the eye, it is important to remember that they are simply animals just like us. It is important that we work together to preserve their habitats and protect their species.
