Thyroid hormones accelerate the development of white stripes in clownfish larvae

Clownfish larvae treated with thyroid hormones formed a higher number of bands at an earlier stage of development, compared to control larvae that weren’t treated with thyroid hormones. The image shows a control clownfish larvae (top) and a larvae five days after it was given a dose of thyroid hormones (bottom). These findings appeared in a PNAS study coordinated by Prof. Vincent Laudet, from the Marine Eco-Evo-Devo Unit.
