Leaves heart or arrow-shaped, 3-8 cm long, 3 cm wide, wavy edges, both surfaces hairy. The leaf blades sit on the stalk, 6 cm long and attach at a distance of 4-13 cm on the axis of the stem and are 1 cm thick.

Star flowers, mostly yellow to orange, 5 petals and 8 cm long inflorescence axis. The crown tube is 2 cm long in the middle and is black-purple in color. The single flower has 2 bracts, triangular to oblong in shape, hairs that taper outward, 18-20 mm long and 9-10 mm wide.

Petals serrated, 2 mm long, 15-17 lobe-shaped awl. The crown tube is 4 cm long and shows 5 large crown lobes measuring 2 cm in diameter with a capillary bud on the outside. The fruit has a length of 16-18 mm, smooth hair, 7 mm in diameter. Four seeds and 3.5 mm. Seeds germinate easily in humus-rich soil with little sand.

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 ...
