Loop-root mangrove (Rhizophora mucronata)

Loop-root mangrove (Rhizophora mucronata) is a species of plant in the Rhizophoraceae, evergreen, 10-27 meters high, up to 70 cm in diameter, dark to black bark, cracked bark, horizontal, many large stilt roots with a height of up to 2 meters above mud and woody.

R. mucronata has leaves that sit opposite each other, collected at the ends of the twigs, the buds are covered in supporting leaves that are rolled up and pointed and are white or red in color, fall off quickly and leave scars similar to bulging rings. The leaves are elliptical, thick, smooth, green or yellowish, with a pointed tip, have a stalk, 12-24 cm long, 4-13 cm wide.

Flowers are grouped in additional umbrellas, stalked, forked in axils and 4-8 florets. The crown is white, with long hairs up to 9 mm. Flowers all year round. The fruit is egg-shaped, green-brown, 5-7 cm and viviparous. Cylindrical hypocotyl, large, rough, nodules and 36-70 cm long. The cotyledon neck is yellow when ripe.

This species tolerates hard and sandy substrates. More abundant in deeply flooded and humus-rich substrates in estuaries, tidal rivers, flat beaches which are exposed to tidal flooding every day. Sometimes it occurs as a pure stand or may grow with other species.

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 ...

Pink trumpet tree (Tabebuia heterophylla)

Pink trumpet tree ( Tabebuia heterophylla ) is a species of plant in the Bignoniaceae family, growing 6–9 meters tall with a cylindrical trunk and brown bark that is often linearly fissured. The leaves are opposite, compound, with five or fewer minor leaflets. T. heterophylla has striking bright red flowers, tubular, five-lobed, and 5–7.5 cm long. The fruit is a cylindrical pod, up to 20 cm long and up to 1 cm wide. The pod stalk is up to 3 cm long. The pod splits along two lines to release numerous thin, light brown seeds, 0.5–2.5 cm long with two white wings. This species is often used as a street tree and shade tree for residential properties.

Javan mocca or Javan slender caesar (Amanita javanica)

OPINION - Javan mocca or Javan slender caesar ( Amanita javanica ) is a mysterious fungus species and has been enigmatic since it was first reported by Boedijn in 1951 and after that no explanation or reporting of specimens is believed to be the same as expected. Boedijn (1951) described A. javanica which grew on Java island as having the characteristics covered in the Amanita genus. Corner and Bas in 1962 tried to describe Javan mocca and all species in Amanita based on specimens in Singapore. Over time some reports say that they have found A. javanica specimens in other Southeast Asia including also China, Japan, India and Nepal. But there is no definitive knowledge and many doubt whether the specimen is the same as described by Boedijn (1951). I was fortunate to have seen this species one afternoon and soon I took out a camera for some shots. In fact, I've only met this mushroom species once. Javan mocca is an endangered species and I have never seen in my experience in...
