From wikimedia commons The question is not why are whales big but why are whales not bigger? The blue whales reached weights of 150 tons prewhaling. To appreciate how massive a blue whale is, consider it would take 15 school buses, around 10 tons in weight . . . → Read More: Why Are There No Super Whales?

To recap, the National Evolutionary Synthesis Center is offering two $750 travel awards for bloggers with the best posts covering new and emerging evolutionary science. To apply for an award, writers should submit a blog post that highlights current or emerging evolutionary research. In order to be valid, posts must deal with scientific results appearing in 2009. Posts should be 750‐1500 words, and must mention the NESCent contest. The competition so far looks pretty stiff.

The barnacle on top has been fertilized and the eggs are compressed into yellow pellets on either side of the body. The penis is sticking out from in between. The barnacle below has not been fertilized; the un-fertilized eggs are large yellow blobs. The testes are visible in both . . . → Read More: On the study of crustaceous genitalia
