Golden Poison Dart Frog

Golden Poison Dart Frog

One interesting thing about captive breeding is that your captive population is often based on the genetics of the initial individuals collected … often decades ago.

The golden poison dart frog is green (according to the zookeeper I talked to) because, in the wild, there are green ones and there are gold ones. Apparently, the green ones were easier to capture, so most of the ones you see in zoos are green.

This has started to change, as more frogs are being captured to help protect them against the chytrid fungus, so the genetic diversity of the captive population has increased.

Long Tailed Salamander

This salamander is wondering why narrators are always talking about how this building or that can “be seen from space”.

“If we can see can see OGLE-2014-BLG-0124Lb, 76,422,100,000,000,000 miles* away, seeing something from orbit is nothing to brag about.
Even factoring in relative sizes, at half the mass of Jupiter, assuming similar density, OGLE-2014-BLG-0124Lb would have a diameter of 68,957.812 miles.
So, from a low earth orbit of 200 miles up, you should be able to see things that are 0.0000000001805 miles wide. That’s 0.00001143 inches … smaller than a human hair.”

Salamanders think they understand satellite imagery, but they really don’t.

Frogs have been around for a long time. They’ve seen humans learn to play with sticks. They’ve seen humans push those sticks into the mud to make pictures. They’ve seen those pictures turn into simplified symbols. They’ve seen those symbols simplify even further so they could be combined to increase meaning. They’ve seen the increased communication abilities drive global trade. They’ve seen global trade get sped up with computers. They’ve seen these computers translating the simplified symbols into other simplified symbols so people in different parts of the world can understand each other. They’ve seen people work together to improve this process, fostering global understanding and the creation of a world-wide list of characters so computers can understand all language on earth. They’ve even seen what humans do with this amazingly advanced technology.

Was it worth all the effort?


Yellow-spotted Salamander (Ambystoma maculatum)

Yellow-spotted Salamander (Ambystoma maculatum)

From Wikipedia: “The spotted salamander, like other salamanders, shows great regenerative abilities: if a predator manages to dismember a part of a leg, tail, or even parts of the brain, head or organs, the salamander can grow back a new one, although this takes a massive amount of energy.”

I am now envisioning a salamander super-villain who has to drain the life force of others to regrow his limb.
