Brain size riddle solved as humans exceed evolutionary trend

"For more than a century, scientists have assumed that this relationship was linear—meaning that brain size gets proportionally bigger, the larger an animal is. We now know this is not true. The relationship between brain and body size is a curve, essentially meaning very large animals have smaller brains than expected."

If you’re photographing a caterpillar, Kate recommends getting at least three photos: one the top of the caterpillar, one of the side showing all the sets of legs, and a photo of the face (aka head capsule). It’s also really important to note the host plant (or make an observation of the host plant and get it identified on iNat). Even then, she reminds us that not all caterpillars (or adults) can be identified to the species level from photos alone.

If Great Salt Lake were to disappear, an annual five million tonnes of farmed fish and shrimp could disappear with it. That’s roughly equal to the wild seafood the United States and Canada combined manage to catch in a year.

Egg-laying caecilian amphibians produce milk for their young, find scientists

The research team observed that the young of the Brazilian caecilian Siphonops annulatus consumed milk for over two months, which appears to be secreted in response to tactile and acoustic stimulation from the mother's cloaca. The milk consists mainly of fats and carbohydrates and is produced in the glands of the female's oviduct.

First Known Photographs of Living Specimens

This project is designed to showcase the first known photographs of living specimens of any species. Note that by ‘first known’ I’m referring to the first known photographs of a species anywhere, not just the first photographs to be submitted to iNaturalist.

Mysterious new moth species discovered in Europe

The moth, named Mirlatia arcuata, […] is one of the most remarkable discoveries in Lepidoptera of recent decades. […] Initial genetic data from the mitochondrial COI barcode, as well as characteristics of the tympanal organ (auditory organ), point to a largely independent systematic position of the species.
