Prince Albert II centipede (Endogeophilus alberti), a new species in the extremely rare genus

NEWS - Geophilid centipede, Prince Albert II centipede (Endogeophilus alberti), was described based on a single specimen collected from Provence, southern France, which is similar to E. ichnusae Bonato, Zapparoli, Drago & Minelli, 2016, and is known by only three specimens from southwestern Sardinia as the only species in the genus Endogeophilus.

Both species have a very narrow body, very short setae, numerous outer legs and are relatively stout. All these traits are rare among geophilids and suggest an endogeic lifestyle. The two species differ in the shape of the pretarsi of the second maxilla and the shape of the forcipules, although specimens are very few and it is difficult to distinguish between species from intraspecific variation.

Provence is one of the most surveyed areas in Europe for centipedes, but some sectors are still poorly studied. The new species was discovered in southern Provence, about 2 km from the coast, while the known range of E. ichnusae is limited to southwestern Sardinia. The two areas are more than 450 km apart and separated by a wide sea channel.

E. alberti is only known from the type site and a single specimen collected in the shaded maquis by Arbutus unedo L., 1753 and several large Quercus suber L., 1753. It was found after sieving with a Winkler tool at a depth of 10-20 cm in the soil. The species is dedicated to Prince Albert II de Monaco whose foundation has supported the fieldwork of this research.

E. alberti is found in the marginal area (“zone d’adhésion”) of the Port-Cros National Park which was poorly studied before 2022, except for coastal habitats. It appears that E. alberti has a narrow distribution, probably restricted to the Maures mountains and its surroundings, which means that detections are very low compared to most other centipedes.

This renowned biodiversity hotspot in Europe is seriously threatened by demographic pressures and various human impacts, in particular the habitats in the southern Maures have been disturbed by urbanization, artificialization and forest fires. This impact also concerns several species of centipedes (Chilopoda) which are already considered endangered.

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 ...

Javan broadhead planarian (Bipalium javanum)

Cacing palu or Javan broadhead planarian ( Bipalium javanum ) is a species of animal in Geoplanidae, hermaphrodite, living on the ground, predators, often called only hammerhead or broadhead or shovel worms because of wide heads and simple copulatory organs. B. javanum has a slim stature, up to 20 cm long, up to 0.5 cm wide, head wide up to 1 cm or less, small neck, widening in the middle and the back end is rounded, all black and shiny. Javan broadhead planarians walk above ground level by raising their heads and actively looking left, right and looking up using strong neck muscles. Move swiftly, track meander, climb to get through all obstacles or make a new path if the obstacle is too high. Cacing palu track and prey on earthworms and mollusks. They use muscles and sticky secretions to attach themselves to prey to lock in. The head and ends of the body are wrapped around and continue to close the body to stop prey reactions. They produce tetrodotoxins which are very strong...

Sweetpotato bug (Physomerus grossipes)

Kutu ketela or sweetpotato bug ( Physomerus grossipes ) is an insect species in Coreidae, brown with black legs, adults growing about 2 cm long, oval shaped, segmented antennas, heavily veined membranes, metathoracic odor glands and enlarged rear tibia. P. grossipes generally live in Leguminosae and Convolvulaceae especially sweet potato ( Physomerus grossipes ), pink morning glory ( Ipomoea carnea ), purple beans ( Vigna unguiculata ), Asian pigeonwings ( Clitoria ternatea ) and common bean ( Phaseolus vulgaris ). Sweetpotato bugs suck liquid from the stem which causes plants to wither and disrupt fruit production. P. grossipes places eggs at the bottom of the leaves or stems or grass around them. Females are very protective of their children, keeping eggs and nymphs from predators as the most famous example of maternal care in Coreidae. Even so, about 20% of eggs are eaten by predators such as ants and 13% are lost by parasitoid predation by chalcid wasps which lay eggs in egg...
