Longnose spurdog sharks, locally known as kalb al-bahr, are sold on Libyan fish markets. Fishermen catch them even though they are carrying eggs, driven by economic necessity.

The bodies of the crabs displayed male reproductive structures, while other parts showcased female features, including gonopores, said K.S. Anoop Das.

The haul of lobsters, Maine's best known export and a key piece of the state's identity and culture, has declined every year since 2021, and some scientists have cited as a reason warming oceans that spur migration to Canadian waters.

Two Ecuadorian fishermen were among the five detainees, and their immigration records showed unusual activity.

Signs of ageing accelerated when fish were exposed to the chemicals, according to the study, which could have implications for other organisms. Chemical safety regulations tend to focus on short-term exposure to high doses of pesticides and other chemicals, but the study focused on long-term exposure. Low doses of pesticides are widespread in the environment, so their effects should be studied and understood, the authors said.
