Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...

False nettle (Boehmeria cylindrica)

False nettle ( Boehmeria cylindrica ) is a species of plant in the Urticaceae family, a herb or small shrub, up to 160 cm tall, usually monoecious but rarely dioecious. The leaves are paired or alternate, and the inflorescence is a spikelet with a cluster of small bracts at the tip. B. cylindrica generally grows to a height of 50-100 cm. Spine-like hairs form in the leaf axils. The leaves are oval and up to 10 cm long and 4 cm wide. The flowers are green or greenish-white and emerge from the upper leaf axils. Male and female flowers usually grow on separate plants. Male flowers are more numerous among the spikes in clusters. Female flowers are less evenly distributed along the spikes. The small, oval seeds are covered with small, hook-like hairs. Ripe seeds are dark brown. The inflorescence resembles a spike and is up to 3 cm long. This species can be found in moist to mesic deciduous forest habitats, growing abundantly along streambanks, floodplains, and lowlands. B. cylindrica is ...

The flowers have a sweet aroma and attract numerous pollinating insects. The fruit is round, green, up to 4 cm in diameter, with a large seed in the center. When ripe, the fruit wrinkles and turns yellow to brownish. The fruit is light, with thin, spongy flesh and a...
