Pillar Coral.

I sort of arbitrarily picked this species of coral, just because I've never posted a coral. And they are probably among the most magnificent animal types that exist. Also, one of the most important for ecosystem health. People often forget they are animals, because they don't 'move.' They actually do -- they spawn, and on some occasion will extend tissue and eat other coral. Typically they just take in debris. They also have a polyp stage in life, similar to jellyfish. They attach to a surface eventually, and grow from there.

This specific species grows up to 8 feet tall and lives along the Atlantic coasts.
Perhaps most interesting about these (and other) corals is that they can produce sexually as well as asexually. They are also hermaphroditic. So they have both sperm and egg, and can also reproduce by just budding and creating a new coral pillar. Which is why they tend to cluster in large groups.

Unlike most animals, since corals form a geographical structure, they serve a function similar to that of trees in a forest -- they provide nooks for animals and homes for teaming wildlife. They also affect the amount of oxygen and carbon in the water, which is obviously important to any living creature around. And like plants, there are plentiful examples of fish that associate with specific types of coral, both in coloration and in behavior (think: bees or flowers and orchids). They also provide color - a visual masterpiece that compels us to love the seas.

Here's a video to help you learn more about coral reproduction:

Dwarf Mongoose.

Typically between 18 and 25 cm long, these are Africa's smallest carnivores. They takeover large termite mounds and dig larger exit holes -- so you know when they're around. They live in groups of up to 30 individuals, and are headed by a dominant couple, and specifically, a dominant female. This female makes decisions of when to move, when to defend territory, and when to feed.

They have a mutualistic relationship with hornbills for hunting. They'll hunt at the same time -- though they might eat slightly different things, they each observe each other for signals of birds of prey (eagles, hawks, etc), since both must avoid them.

They're pretty common, and you'll likely see them scurry frantically if you ever are camping in sub-saharan Africa.

Emerald Tree Boa.

I've never posted about snakes, so I thought why not. This S. American boa is relatively common, but I think demonstrates the structure of a snake well. If you can get over your fear of them, it's a pretty elegant animal. They are distinctive for their positioning -- they rest on branches in the form seen in picture 2, and at night sit on low branches so it can attack small mammals by just reaching down and grabbing with its teeth. For a venomous snake, it has the largest proportioned teeth.

Depending on where in the continent they are, they have different features -- sometimes slightly different designs, different lengths (the longest are around 6 ft.) and slightly different colors. The last picture is actually of a juvenile -- they're born red and slowly turn green as it matures. Why? Perhaps because red is a color that predators avoid -- and as a baby, perhaps they are less coordinated and can be easily spotted, so this might keep others away. When older, it can move smoother and can easily blend in, thus having camouflage rather than warning signs. It's easier for hunting.

The juveniles eat glass frogs primarily, and for some reason change their diet to largely mammals later. Adults eat very rarely. Since their digestive system is so slow, it can be months between one meal and the next.

The last thing about that stands out is their reproductive system, which is actually similar to whale sharks. They are ovoviviparous, meaning the eggs are within the body and are hatched before leaving the mother's body, leaving as a live birth. This is unusual for a snake -- perhaps a development that came as the snake lived almost exclusively in trees -- the eggs are mobile this way and aren't easily crushed from a fall.

Satin Bowerbird.

There is a lot to say about bowerbirds. These Australian birds have perhaps the most complicated courtship ritual of any bird species. If new to you, it might also call into question your conception of art and creativity in humans.

Bowerbirds (male = picture 1, female = picture 2) build bowers (picture 3). Well, just the males do. Bowers are structures made from sticks, flower stems, rope... whatever is around. These structures form either dens or u-shape structures, and are not actually nests. Their only purpose is for mating displays. While most birds use feathers, calls and dances to attract females, this one adds an extra layer; design. Each species of bowerbird forms different shapes, but each individual designs their bower differently. They find objects from their surroundings (or steal them from other bowers) to decorate their bower. This can be by texture, color, shapes, you name it. And are arranged carefully to the point that it looks intentional. An individual's design might attract an individual type of female.

What's even more peculiar is that the females visit the bowers before seeing the males. They choose which they prefer, then later comes to the site when it is further to completion -- some decisions about the mate have been made entirely on the bower. Then the female returns when the male does calls, displays, etc. It is thought that this bird is especially unique because its physical attributes may be negated by its creations. So if it has bad feathers, it might be able to make up for that by having an exceptional display, or a refined call. Other birds can't do that -- they've just got to flaunt what they've got.

But why wouldn't the female use color to assess its mate? That seems to be the case in other bird species, and it can be telling of a birds health. In this case, the creativity in a bower might suggest its ability to acquire goods and hold territory better than other males; a valuable ability for sure.

The bower's functionality itself is still not entirely clear. The satin bowerbird's structure is somewhat understandable, in that it is essentially a contraption... during copulation, a female walking through the bower might not be able to fly away, since its wings cannot spread. This isn't the case for all bowerbirds though. And before you think this forced copulation seems aggressive, keep in mind that the female has chosen an individual based on the bower long before visiting the site and sometimes visits multiple times to hear its call and watch his display as well. So it seems the female has to let copulation occur -- maybe the structure is a remnant of a behavior its ancestor had when perhaps forced copulation was the norm? Who knows.

So why does this call into question our sense of art and creativity?

We often think most animals work mechanically, with the exception of us. They just "do" things and don't think about it. There's no control over its actions.

This might still be the case with this bird -- it might be a natural preference and each bird might have a gene that makes it get one color over another, or one shape over another. But the point is each is different and each artful display holds no functional value other than impressing the other sex (the fruits, flowers, seeds, shells, etc are never used for feeding, protection or health). Though we don't label our art quite so directly, when we do similar things, we say it's not to attract others (because that's what's favorable to others) and we say it comes from creativity that involves individuals thought. And we convince ourselves of this.

It's not to say we don't have individual preferences that require thought or creativity, but how are we any different than this species in that regard? Either our creativity is innate for validation or attraction or these birds have significantly more thought than we would like to think and don't give them credit. When we study other animals, it seems obvious that it's the first option and it seems like we just say that can't be the case for us because it makes us feel better and... uh-oh.... validate our creativity.

Regardless of your thoughts, it's an incredible display and I personally think it applies to people very well.

Here's a video feature the wonderful David Attenborough:

Spanish Moon Moth.

This moth, native to Spain and France looks like it came straight from a fairy-tail. For some reason, moth's don't get much credit, but butterflies do. It seems strange -- I guess most common butterflies seem more colorful than common moths for most people.

These live in almost exclusively in pine trees, and come in white and green forms. The thin lines and their color make it difficult for predators (birds) to find them, since they are surroundd by thin pine needles. And like other moths and butterflies, it has eyespots on its wings, so even if it is spotted, many animals would be scared of it, thinking it is an animal much more fierce and large than it actually is.

Whale Shark.

This wonderful giants are the largest of all living fish (it's not a whale). This shark is named so almost entirely based on its size. They can grow up to about 40 ft. and can weigh up to 15 tons (30,000 lbs!) and like elephants, they can live up to 60 - 70 years (reports estimate some might be over 100). Impressive, no?

Around the world, there are different names for them, most based on shapes on its back... in Kenya the story is someone threw shillings on its back, in other places the name literally means 'starts on its back' but my alltime favorite: "Ca Ong"... Vietnamese for "sir fish."

Their life cycle is also interesting. Typically, you hear there are 3 birthing classifications of animals... monotreme (they lay eggs), marsupial (pouch... animals are born premature) and embryonic (matured by mothers nourishment in womb). Whale sharks have something similar to the first and last of these types. They are ovoviviparious... meaning they have eggs, but they remain in the body, are hatched and followed by a live birth. This is different than embryonic because they are nourished through yolk in a closed egg, versus being nourished through tubes connected to the mother. They can give birth to up to 300 pups (yes, shark babies are called pups).

As large as they are, they are known for being gentle. The only injuries they have ever incurred on people are from accidental hits from its tail fin. In fact, they're normally playful with divers.

The other similarity they have to whales is their feeding -- they are a type of filter feeding shark (only 3 species in the world), meaning they eat krill, phytoplankton and occasionally small squid or vertebrates. Apparently when things bigger than that are caught and line the filter, they have been seen to 'cough' as a mechanism to clean the filter. A shark coughing is a funny image. They also swim really slowly... average top speed: 3.1 mph. They have quite a lot of weight to move, so I guess that's fair.

You can find them all over the world in the tropics.... Carribean, India, Africa, Japan, Hawaii, you name it. And they come relatively close to the shore, so if you are a diver, you can see them somewhat often if you are looking specifically for them.

There are a few places you can see them in aquariums... Japan, Taiwan, and the Georgia Aquarium.

Here's a wonderfully relaxing video from Okinawa aquarium in Japan (featuring other fish, too):

Lychee Stink Bug.

Actually this 'stink bug' is not related to most stink and shield bugs, it's in a different family. But they have the same function, and resemble the others in shape. Like the others, if agitated, with release a pungent secretion (sounds gross, doesn't it?) to fend off predators and perhaps even trick a couple that its dead. And if you've been following my blog, you'll know that not all insects are bugs -- bugs are a specific type of insect. And this one is correctly named and is actually a bug.

Their colors are striking and are mostly to blend in with flora in the area (they can be found in Thailand). It is also used to trick birds into thinking their are poisonous. Not many terrestrial living things have blue colors (outside of birds) and red is typically a sign of poison of sorts (think: poison dart frogs). The first image is of a nymph (immature) and the second is matured -- the additional section of the bug is actually its wing case -- nymphs are flightless.
