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 ...
The suborder Suina consists of 20 extant species in nine genera, divided into dozens of extant subspecies. These are split between the Suidae family, containing 17 species belonging to 6 genera, and the Tayassuidae family, containing 3 species in 3 genera.
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 ...
Marine ecosystems can be divided into many zones depending upon water depth and shoreline features. The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live. The benthic zone consists of substrates below water where many
[2] [3] Marine microorganisms have been variously estimated to make up about 70%, [4] or about 90%, [5] [6] of the biomass in the ocean. Taken together they form the marine microbiome. Over billions of years this microbiome has evolved many life styles and adaptations and come to participate in the global cycling of almost all chemical elements ...
