It's a hot summer's day and you're at the beach for a well deserved day of leisure, enjoying the refreshing water and a picnic.

Fish devastated by sex-changing chemicals in municipal wastewater

When they're ready to mate, silkworm moths emit special chemicals in hopes of drawing males to their location. Those chemicals are so powerful — and so magnetic — that male moths will travel up to 30 miles 48 kilometers for a chance to mate, tracking the female with just a few precious molecules of her scent guiding his way. The intoxicating chemicals are called pheromones. Pheromones are special chemicals produced and secreted by living creatures, in small amounts, for a variety of purposes. Organisms use them to signal something danger, territory, readiness to mate and so on to another member of their social group or species. Scientists have confirmed the importance of pheromones in the lifecycles of many creatures, from elephants to crustaceans, insects to fish. In many ways, pheromones are like hormones that act outside of the body.

Male Frogs May Be Turning Female Thanks to Estrogen in Suburban Waste

Millions of people saw a dramatic example of this in the first episode of Blue Planet II, in which a ten-year-old female kobudai also known as an Asian sheepshead wrasse, Semicossyphus reticulatus changes into a male. After many months, the transformed male emerges from its lair larger than before, bearing testes, a huge bulbous forehead, and an aggressive nature. Now even larger than the existing dominant male it had previously mated with when female, the new male defeats the aged alpha in a violent battle for dominance. The footage is remarkable — but the transformation is actually not terribly unusual. Some like the kobudai change routinely from female to male.

The exchange of chemical signals between organisms is considered the oldest form of communication. Acting as messenger molecules, pheromones regulate social interactions between conspecifics, for example, the sexual attraction between males and females. Fish rely on pheromones to trigger social responses and to coordinate reproductive behavior in males and females.
