The common warthog is a medium-sized species, with a head-and-body length ranging from 0.9 to 1.5 m (2 ft 11 in to 4 ft 11 in), and shoulder height from 63.5 to 85 cm (25.0 to 33.5 in). Females, at 45 to 75 kg (99 to 165 lb), are smaller and lighter than males, at 60 to 150 kg (130 to 330 lb).
They are largely herbivorous, but, like most suids, opportunistically eat invertebrates or small animals, even scavenging on carrion. [4] While both species remain fairly common and widespread, and considered to be of Least Concern by the IUCN , the nominate subspecies of desert warthog, commonly known as the Cape warthog ( P. a. aethiopicus ...
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
The Atlantic Ocean is teeming with life, but for the first time researchers have discovered dead zones in these waters - areas low in both oxygen and salinity - off the coast of Africa. Fish can't ...
Artiodactyls live on every major landmass and throughout the oceans and in a variety of habitats, including forests, grasslands, and deserts. They come in a wide array of body plans in contrasting shapes and sizes, ranging from the 38 cm (15 in) long and 2.5 kg (5.5 lb) royal antelope to the 27 m (89 ft) long and 120 ton blue whale.
Pelagic zones. The ocean can be conceptualized as being divided into various zones, depending on depth, and presence or absence of sunlight.Nearly all life forms in the ocean depend on the photosynthetic activities of phytoplankton and other marine plants to convert carbon dioxide into organic carbon, which is the basic building block of organic matter.
The ocean is separated into layers with the surface layer (or sunlight zone) reaching down to 660 feet. Beyond the sunlight zone lives the Pacific Viperfish. This is known as the twilight zone ...
