29-12-2022 NGALA LODGE, GAMBIA - TYPICAL JUMPING SPIDERS (Hyllus plexippoides)
%202.jpg)
Geographic Range: This species is found across a range in Africa, specifically from the Ivory Coast, Guinea, and the Democratic Republic of the Congo to Sudan, Kenya, and Zambia.
Appearance: Spiders in the Hyllus genus are typically medium to large, stout, and hairy. They are often dully colored with a rounded carapace (the head region), but specific markings for H. plexippoides are not widely detailed in general sources.
Behavior: They are diurnal, active hunters that do not build webs to catch prey. Instead, they use their powerful hind legs to jump and pounce on insects and other small spiders.
Vision: Jumping spiders possess remarkable vision with eight eyes, including two very large forward-facing eyes that provide excellent depth perception and detailed, full-color vision. This sharp eyesight is crucial for their hunting and navigation.
Safety: They pose no significant threat to humans. While they can bite if severely threatened, the venom is not medically significant and a bite is typically mild, similar to a mosquito bite.
Habitat: Like other jumping spiders, they are found in various habitats, including vegetation, under bark, and on tree trunks. At night or during bad weather, they create small, protective "pup tents" of silk for shelter, molting, and laying eggs.
19-12-2015 JURONG, SINGAPORE - WHITE WINGED DUCK (Asarcornis scutulata)
Historically, the white-winged duck was widely distributed from northeastern India and Bangladesh, throughout South East Asia to Java and Sumatra. It is now extinct in Java. In India, the duck is found only in the northeastern part of the country, with the main concentration in eastern Assam and adjacent areas of Arunachal Pradesh. However, in 2002 it had a population of only 800, with about 200 in Laos, Thailand, Vietnam and Cambodia, 150 on Sumatra, notably in Way Kambas National Park and 450 in India, Bangladesh and Burma.
In India, the key protected areas for the white-winged duck are Dibru-Saikhowa National Park, Dihing-Patkai Wildlife Sanctuary, Nameri National Park and Namdapha National Park.
The white-winged duck occurs in dense tropical evergreen forests, near rivers and swamps.
They tend to nest in tree cavities, and are threatened in part since the destruction of hollow trees is destroying their nesting localities. The draining of swamps and rivers and other forms of habitat destruction is also destroying the habitat that they could survive in. Additional threats include loss of genetic variability, disturbance, hunting, and collection of eggs and chicks for food or pets.
