"Shrinking Right Whale Population Faces Drastic Consequences"

Critically endangered North Atlantic right whales are shrinking in size, leading to reduced calving rates and threatening the survival of the species. A study found that smaller females had fewer calves, with body size being a significant factor in their ability to reproduce. The declining size is attributed to stressors such as climate change and reduced nutrient availability. With only 356 individuals believed to be alive today, urgent protections are needed to prevent their extinction, including updated vessel speed limits and stronger regulations to reduce the risks and stress faced by these whales.

The Massive Testicles of Right Whales.

The North Atlantic right whale has the largest testicles in the animal kingdom, weighing around 450-500 kg each when fully grown, which is about the same as a Volkswagen Beetle. However, their testicles are concealed within their body due to the temperature of the ocean water. The whales produce 4.5 liters of sperm, which is a means of "flushing out" the competition during copulation. Older male whales are more likely to successfully breed, which complicates conservation efforts and reduces genetic diversity in whale populations.

Lobster and Crab Industries File Lawsuits Over Listings and Price Fixing

The Maine lobster industry is suing the Monterey Bay Aquarium in California for defamation, arguing that their prized catch shouldn't be on a "red list" published by Seafood Watch, a conservation program it operates. The aquarium says its recommendations are correct based on the best available evidence, but the lobster industry argues that the recommendation relies on bad science and incorrectly portrays lobster fishing as a threat to the endangered North Atlantic right whale. The lawsuit asks the court to force the aquarium to remove "defamatory statements" from its website and materials.
