Why are some animals ‘wallflowers’ and others are ‘social butterflies’?
An animal has many reasons to behave more like a ‘wallflower’ vs. a ‘social butterfly’. Some of the more universal reasons to lean to one behavior more than the other would be 1) habitat, 2) predators or 3) availability of food. For instance, river dolphins (pictured right) typically are solitaire animals because their habitat is […]
What gives a beach its unique features?
Tides. Winds. Waves. You might think of those right away when you ask yourself “Why are beaches so different from one another?” The story of how and why beaches are unique is more than what we witness while lying in a beach chair watching the tide go out hour by hour. The personality of a […]

In particular from this exhibit, the piece ‘Persian Ceiling‘ is an experience I wanted to share. As I gazed up […]
Are laughing gulls really funny?
NO! Not at all. Laughing gulls, or Larus atricilla, are quite aggressive. These birds travel up and down the coasts and never have to stray far inland. They are extremely confident and spend their days foraging food from overly-relaxed beach goers. They will easily push larger birds, for instance, a pelican, right out of the […]
Who was the first person to explore the deep sea?
New records are always being broken, but, the first person to make it into a deep abyss and record his findings was William Beebe. William Beebe never set out to become an ocean explorer and did not make his record breaking trip until he was 57 years old. Up until then he was content as […]
