Creature Feature: Sawblade Shrimp.

With vacation pics over with, it's time to get back to what this blog is all about: becoming inspired by how weird and wonderful the world is. Yes, believe it or not, this blog has a point- to get people all fired up about how amazing the world already is, and to then use that information to fuel creative projects. So let's head to the oceans again; there's always more than enough weird stuff, there.

If you'll look to the above pic, you'll see a red thing that looks almost like a branch, but not quite. That's a saw-blade shrimp (Tozeuma). It's yet another weird resident of the Indo-Pacific reefs, as well as the Red Sea. They grow 5cm, or roughly 2 inches, and feed on parasites, algae, and plankton.

These are pretty much the walking sticks of the sea. Of course, since this is the ocean, the weirdness has been cranked up to eleven. Banded saw-blade shrimp have bands (go figure)that break up their outlines, as well as transparent bodies. The ocellated saw-blade shrimp above simply looks a lot like the coral it's attached to.  Now you see it, now you don't.

Along with being simply excellent at camouflage, these shrimp have some important jobs to do. As previously stated, they eat parasites. Those parasites come off of other, larger animals that allow themselves a free cleaning from the shrimp. The saw-blades will also clean burrows, jaws, and other things that animals simply can't be bothered to clean.

There are also a ton of saw-blade shrimp waiting to be discovered, or at least named properly. Some people take excellent photos of unknown shrimp when they go to reefs on vacation. There's still a lot to learn about these bizarre, hunched crustaceans. And no, what they taste like is not on the list of things to learn...although a few oddballs have probably tried.

Creature Feature: Longhorn Cowfish.

The idea of "you can slap any word onto 'fish' and it's probably a thing" makes for a rather funny game. Triggerfish are subtle; there is a trigger there, but it's not obvious unless you're looking for it. Surgeonfish? Yeah, I don't get it, either, but I wouldn't trust it with open-heart operations either way. Squirrelfish do not look like squirrels - period. Then there are cowfish...

...yeah, that one works pretty well, actually.

Cowfish are members of the boxfish family, which are closely related to pufferfish. Yes, like fugu, these fish are poisonous. They are native to tropical waters; many of them can be found in the Indo-Pacific. They eat crustaceans, like fish and crabs, as well as plants like algae. The longhorn cowfish ( Lactoria cornuta) is the most popular.

Cowfish are best known for, well, looking like cows. They have boxy bodies and long horns coming out of their heads. Like cows, they are also tanks; the scales on this fish's body are fused into a tough shell. They are slow swimmers and grunt when captured. We'll cut the fish some slack because a mooing fish would be just crazy, and they look enough like cows without sounding like pigs. Moo.



Cowfish have another defense aside from looking like cows: if irritated, they excrete a nasty poison. It is called ostracitoxin and cannot be broken down as it is not a protein. It is hell-bent on destroying other fish, and is hemolytic to boot. It kills sharks. Even other boxfish are not immune to one PO'd cow. The meat is also poisonous. No cowfish steaks for you!

Good gods, cowfish are popular in captivity. They are available at Petco if the online search results are any indication.  This does not mean they are beginner fish - it means that you need to read directions. Cowfish are generally peaceful, easy-going fish that take their time and do not like stress from having a lot of tankmates.  Failing to acclimate them properly may result in poisoning your whole tank. Popular, but still not for beginners, so if you're a newbie, don't get a cow, man.

Creature Feature: Dugong.

Ever wonder how stories of mermaids got started? Like, who decided to put a hot lady on a fish's body? It was obviously someone very drunk and/or creative. It's not like a normal person could look at any sea mammal and go, "hey, that looks like a woman with a tail! I should say hi."

Oh, hell. With a tail like that and a little bit of liquor, that could totally pass for a mermaid.

That, by the way, is a dugong (Dugong dugon). No, not Dewgong- the animal came first. Dugongs are sirenids, making them related to manatees and, more loosely, elephants, tenrecs, and hyraxes. They live in most of the warmer waters around the world, including those around Africa, Australia, China, and the islands around those areas. They are mostly herbivorous, but some populations are omnivores, munching on invertebrates when grass is not available.

For those of you curious about the nomenclature, the odd name comes from the Malayan word for "mermaid." The idea seems pretty universal, with people all the way in Kenya considering dugongs feminine. Indonesians even consider them reincarnations of women. If any sea mammal can be considered a basis or mermaids, this is the one. Instant mermaid: just add rum.

That said, outside of being mermaids, dugongs are fascinating creatures. The tail is fluked like that of a whale or dolphin; this allows it to 'stand' in shallower waters and keep its head above the sea in order to take a breath. Speaking of, dugong lungs are very long, extending all the way down to their kidneys. This arrangement helps balance out the dugong's buoyant blubber.

The dugong is always culturally-significant in the areas in which it is found. Catching a dugong can be seen as either good or bad luck, depending on where you go. In Thailand, the tears are an aphrodisiac; the Indians are more rational and use its meat for sexual potency. The list of things dugong can be used for goes on, possibly into the Bible.

Under the sea, under the sea~


Alas, the dugong is nearing endangered status, and it's entirely our fault. Its meat, oil, skin, and bones are all valuable. They are big, docile, and slow-moving, making them easy targets.  Let's not even get into how humans are polluting the ocean and cutting up sea cows with boats. Once you learn that everybody eats dugong meat, all other reasons seem miniscule by comparison. Luckily, most areas with dugongs have some regulations on hunting them. Good luck enforcing that.

Oh, and yes, dugong has a Poke-sona in Dewgong, the evolution of Seel. Real dugongs, however, cannot handle icy water period, let alone swim through it at high speeds. Sorry, but this Water-Type will not be learning Ice Beam aaaany time soon. Still, save the mermaids!

Creature Feature: Frogspawn.

Corals are pretty strange as far as animals go. Supposedly they're alive and slightly poisonous, but a lot of people treat them like rocks anyways. They make jewelry out of coral, making it effectively the most macabre jewelry ingredient after bones and claws. There are, however, soft-bodied corals...and then there are corals like this:



This coral, Euphylla divisa, goes by the charming common name of "frogspawn." It's native to the Indo-Pacific and can be readily found in the aquarium trade. It's also called the Wall, Octopus, or Honey coral. They're pretty much living acid trips in terms of color possibilities. Y'know, as if crazy tentacles weren't enough to suggest drug use.

Just as a little refresher: Corals are usually made of thousands of teeny-tiny polyps. Said polyps live on the calcified remains of their ancestors. A single "head" of coral is also made up of genetically-identical individuals. It's as if that one church in the Czech Republic was made entirely out of the bones of one, cloned individual. That said, Corsola, you scary.

I live on the bodies of my dead brethren! :D


Frogspawn is still a stony coral, but it has exceptionally-large polyps. These polyps are bubbly, green things that resemble frog or fish eggs, hence the name. The main identifying trait, however, is that the polyp is bifurcated. This distinguishes it from a few other species, most notably grape coral (which has only one, unified tentacle as opposed to split).

There is some concern about over-collection from the wild. Frogspawn is a very common coral in the trade, so there's not much need to get a wild-snagged specimen. They take two years to propagate in the wild. Just make sure that 1) you know how to handle a reef tank and 2) you ask where the corals came from. No need to harm reef systems to look at a living work of art anymore.
