“There are more dangerous things than Orcs in the deep places of the world.”–Gandalf
My never ending obsession with the deep sea and the myriad of creatures that either do or could live in the sea used to be somewhat of a plague in the beginnings of my blogging. Rarely a month went by when some mention of sea monsters, Cthulu, or the myth of Atlantis went by. The sea is filled with creatures more dangerous than anything that walks on the land and an exhibit at the Myrtle Beach Aquarium showcased several of the underwater weapons that evolution has developed for the denizens of the realm of Neptune. They ranged from the odd to the absurdly powerful, it seemed that the smaller of the creature the more dangerous it actually is. Being the person that I am, I found all of this to be absolutely fascinating, scary, and cool at the same time so I’ve decided to put this in list form.
(I took these pictures with my cell phone camera and are as accurate as I could determine, the two shrimps may be switched)
The Box Fish:

Imagine that you are threatened with perceived impending doom. You usually have two options, options that are ingrained in every living animal for survival: fight or flee. The great majority of creatures pick flee (or hide) and have developed numerous mechanisms for speed and treachery. The other creatures, the fight creatures, attempt to scare off their potential attackers or in some cases merely step up for a little bit of fight club. Others rely on poison, they take the initial attack and then set back like Lucrezia Borgia to watch the death ensue. Then there’s the box fish (note the boxy shape of it), which is more like the main character from the movie Predator. Remember the end of the first Predator movie where Arnold has the thing cornered and it begins to laugh as it arms a low level nuclear device not caring that it was going to die as long as it took everyone else with it? Yeah, this fish is like that. When it feels threatened, which is often, it lets loose a poison gas cloud that fills up the surrounding area temporarily paralyzing or killing everything around it. Unlike most poisonous fish, the Box Fish isn’t immune to its own poison. Which means that if you have this thing in an aquarium chances are that you will wake up one day to the maniacal laughter of the Box Fish as it takes out an entire ecosystem.
The Moray Eel:

Since we did the Predator it’s only fair that we also do the alien from Alien as well. First off, the thing just looks both threatening and cool at the same time. It looks like a snake which for most people is already off putting but then it also has teeth which makes it somehow worse. It lives underwater which it means it can automatically out fun you. Evolution has given it something different, something eldritch, and certainly alien. Behind that strange mouth, beneath those fearsome teeth lies another mouth. The Moray Eel has two mouths to feed, and not because it’s a responsible parent either. That outward mouth, the “normal” one, is designed for catching and wounding, the inner mouth is the one that clamps down on the food and drags it into the eel’s digestive system. A placard at the Aquarium said that this was the inspiration for the Xenomorph in the Alien series. Thank you nature, once again, for showing me that the creatures of my nightmares are only mockeries of things that really exist.
The Pistol Shrimp:

If you look at the right of the creature you will see a small claw, it’s really the other claw I wanted, but let me explain this beauty. It’s called the “Pistol Shrimp” because it hunts by shooting bubbles from a quickly closing claw. Doesn’t sound too bad right or even that amazing, but trust me: it’s what happens when the weapon is fired that makes all the difference. The snapping shut of the claw takes place in a mere 300 microseconds forcing jets of water that have been clocked around 62mph. This would allow it to flip just about anything that it wanted over or out of it’s way, but that’s not the weapon merely the gunpowder behind the bullet. As the stream of water goes forward it generates a low pressure bubble which then collapses creating a deafening sound that then dazes and stuns it’s prey. It’s a fucking shrimp, and it’s just over 2cm long and the sound it makes has been measured at 218 decibels. For comparison sake the human threshold for pain is at 120 decibels, and close proximity to a jet engine is a mere 160db.
It gets weirder as well. When the low pressure bubble collapses (a process called cavitation) it is so intense that it actually generates light and the internal temperature of the bubble is measured at 10,000 degrees Kelvin (18,000 degrees farenheight), just so you know the temperature of the surface of the sun is 5,778 Kelvin. Again, this Shrimp is only 2cm long.
The Mantis Shrimp:

This much larger cousin of the Pistol Shrimp is no less strange and no less cool in the unique muscle arrangement that makes it one of the most powerful creatures on the planet (relative to size of course). Housed in its striking appendage is a horseshoe shaped spring, unique to this animal alone in the entire kingdom, which allows it to move the claw at a top speed of 23 meters per second, underwater. The picture above doesn’t show that the shrimp is being held in bullet proof glass because of the tendency of these things to punch holes in double walled tanks. If you’ve ever been to an inner city 7-11 and noticed the thick walled plastic that the teller is behind, that’s what they need to encase this thing in or else it will break loose. Not because it needs freedom, but rather because it’s kind of a dick. Rather than walk around a piece of debris it instead prefers to obliterate it with the strongest punch on the planet. If it were the size of a person there would be very few things on the Earth, aside from the Earth itself, that could withstand it. All because this little guy decided to use the horseshoe as a weapon instead of building a shell with it. Sometimes evolution is just being an ass.
The Box Jellyfish:

[Note: this picture is not mine, the jellyfish was missing from its tank that day]
This is an odd creature. It’s called “box” because of the square shape of its bell which is fairly unique among jellyfish. Unlike most of its kind this thing can actually move instead of just drifting at a speed of four knots. It has fairly complex eyes four sets of sex, one on each side; possessing iris, cornea, retina, and a lens but no nervous system. There is a debate as to whether the creature hunts its prey or is merely an opportunist, but give the deadliness of the creature I’m of the opinion that there is no way it needs to be that powerful if it is an opportunist. If you get stung by this malevolent being, you are screwed–the poison contained in one of these things is enough to kill 60 adults. The nematocysts (stingers) inject not just one type of toxin but several. The first is a cardio-toxin that directly attacks the heart turning it into a big pile of mush that is unable to pump blood. The second is a paralytic neuro-toxin which causes extreme pain, muscle cramping, neural system shut down and the desire for the sweet release of death. The third is dermatonecrotic, which causes extreme pain at the sting site and rots the skin. There is an anti-venom but that will do little good for you because the creature is transparent with a light blue tint making it nearly invisible in the water, which means that no one will know it was there. The only real defense you have is stay the hell away from the waters of Australia.
The Blue Ringed Octopus:

[Not my picture since the rings only show up when this thing is angry and I'm sure there is some law against museums building contraptions to piss these creatures off]
Octopi and Squid are some of my favorite animals in the sea primarily for one reason: there is no limit to how big they can get. Most animals are limited by the structural integrity of bone, you will never see a human over 10 feet tall because the weight can not be supported by bone. Cephalopods don’t have this worry as the only cartilage they possess is in their non-weight-bearing beak, those reports of giant Krakens attacking boats ala Jules Verne, while improbable is at least possible. In the dark deep ocean there could be a 100 foot (not counting tentacles) Squid waiting, plotting…
This octopus however is not one of those creatures. In fact it’s one of the smallest Octopi measuring between 5 and 8 inches. Again, though, it’s the poison that makes it a killer. The salivary glands of the creature contain a bacteria which produces its venom, a venom which possesses 10 different toxins that in combination have no known anti-venom and is entirely fatal. If you are ever in the water and see a small yellow octopus become spotted with blue rings remember this, “before you die you see the rings.” Swim the hell away! It’s not cute, it’s not pretty, it’s nature’s warning for you to get out of the water and move to the desert. The primary toxin is TTX (found also in Puffer fish-which are pretty lame otherwise), which blocks the movement of sodium ions across neural fibers causing paralysis of the muscles and heart. The victim dies within minutes of asphyxiation if rescue breathing is not administered right away, the worst part? That said victim will be completely conscious despite all outward appearance of being dead (dilated and fixed pupils, lack of breathing).
