This larva looks a little nervous. 😰 😬
You’re looking at the development of the nervous system in a fruit fly embryo as it transitions to the larval stage. The nuclei of all its cells are labeled in red and the cells of its nervous system are labeled in green. The jerky movements towards the end of the video are a result of the nascent larva developing its musculature and beginning to move. The front of the larva – which will become the head of the fly – is at the bottom in this view.
This glimpse of nature at its finest is one of many hidden wonders uncovered through basic science and brought to you by HHMI’s Beautiful Biology.
