When they say "be there or be square", today's Wet Beast Wednesday subject chose "square". I am referring to boxfish. Also known as cowfish, trunkfish, and cofferfish, these real-life Minecraft fish are bony fish in the family Ostraciidae, sometimes called Ostraciontidae. This makes them close relatives of pufferfish and file fish in the order Tetraodontiformes. While all the Tetraodontiformes are weird-looking fish, the cowfish are easily the strangest, they don't even really look that much like fish.

(image: the yellow boxfish Ostracion cubicum. They literally named it "cube")

The squarish shape of the boxfish comes from their unique skeleton. They have a carapace made of overlapping, hexagonal plates called dermal scutes that are the equivalent of scales in other fish. Each plate is composed of a soft and bendable collagen layer and mineralized surface layer. This carapace is very sturdy, with holes in it to allow for the eyes, mouth, fins, and cloaca to pass through. In game terminology, the cowfishes are stone walls. Because of the composition of the carapace, boxfish are fully rigid and cannot bend their bodies in any direction. This, combined with their not-overly hydrodynamic shapes, makes them slow and weak swimmers. When they filled out their character sheets they went all-in on defense and neglected speed and offense. A boxfish won't be winning any races, but the carapace is extremely hard to bite through or puncture, giving an effective defense. Despite their small sizes (the largest species can get up to 50 cm/20 in long, and most species are much smaller), adult boxfish have almost no natural predators. It's worth noting that while boxfish are slow swimmers, they are very maneuverable. They have the ability to create small vortices around their bodies to help maneuver.

Not satisfied with having an impenetrable shell, many species of boxfish developed another defense mechanism. When stressed, they can release poison into the water. These poisons are surfactants, substances that break up surface tension, that can damage the cell membranes of other animals. While each species has their own specific chemical and not every species is poisonous, these toxins are collectively called pahutoxins. Poison is a pretty common thing in the Tetraodontiformes. Famously, pufferfish, close relatives of boxfish, are highly poisonous. Most poisonous boxfish species are brightly colored. This is called aposematism and is used as a warning to potential predators that the animal is dangerous. A famous example of aposematism is the brightly-colored poison dart frogs. Young boxfish are typically more colorful than older ones.

Boxfish are voracious omnivores that will eat just about anything that can fit in their tiny mouths. The majority of boxfish species live in coral reefs and their diet consists largely of algae that they scrape off of coral. Additional foods include sponges, tube worms, mollusks, and small fish and invertebrates. Some species can spit out water to blow aside sand and search for buried food.

(image: Ostracion meleagris, the spotted boxfish)

Boxfish are typically solitary, but occasionally come together in small groups. These groups typically consist of one male and a few females. Scientists speculate these groups are formed for reproduction. They are known to reproduce by swimming to the surface of the water, releasing their gametes, and quickly swimming away.

(Aracana ornata, the ornate boxfish)

Because of their unique appearances, boxfish are popular in aquariums. They are recommended for experts only because of their ability to release poison. Boxfish are easily stressed and can kill themselves and other tank-mates by releasing toxin. Aquarists usually say they should be kept in solo tanks or with smaller, mild-mannered tank-mates. In addition, they need to be in tanks with minimal water flow as even the current of a decently-sized filter can blow them around uncontrollably. People who keep boxfish have called them shy, but highly inquisitive and even playful. They have been reported spitting water and their handlers, apparently in an attempt to get attention.

Aracana aurita Shaw's Cowfish #marineexplorer #UNSWbees #GSRfieldtrip by John Turnbull Via Flickr: Similar to A ornata; both species can be found under the jetty at Port Noarlunga. In both cases the females are brown, orange/yellow and white striped, and the males add blue to the palette. See reeflifesurvey.com/species/aracana-aurita which has a neat "similar species" section

Ornate cowfish (Aracana ornata)

The Ornate Cowfish is a species of boxfish native to the Eastern Indian Ocean. It has a maximum length of 15cm. Ornate Cowfish are sexually dimorphic; males have yellow or blue lines and spots, while females are plain with orange-brown stripes. Stress can cause them to release ostracitoxin from their skin.
