13-7-2017 MONTE ORONA, VALENCIA - CONTINENTAL STRIPED SHIELD BUG (Graphosoma italicum ssp italicum)
The so-called "striped bug" in Spanish, Graphosoma lineatum subsp. italicum (Müller, 1766) , is a subspecies of the so-called "shield bugs", due to the shape of its scutellum, and belongs to the Pentatomidae family . Pentatomidae comes from the Greek and means "in five parts", referring to its antennae composed of 5 segments, compared to the 4 of other bugs. According to some authors, the species Graphosoma lineatum (Linnaeus, 1758) is divided into two subspecies. The typical one, Graphosoma lineatum subsp. lineatum (Linnaeus, 1758) , seems to be distributed in northern Africa and possibly the Iberian Peninsula and southern France. The other, Graphosoma lineatum subsp. italicum (Müller, 1766) is more widely distributed, in the Mediterranean and Euro-Siberian areas, reaching as far north as Denmark. Other authors give the latter the status of species, and it is now called Graphosoma italicum (Müller, 1766) .
This is a showy bug, 8-12 mm long in both males and females, with a flattened, almost round body, similar in appearance to a shield, and with a face that clearly protrudes from the head. This shield ( escutellum ) covers almost the entire abdomen, is triangular in shape and is usually as long as the corium of the elytra.It is easily identifiable by its reddish aposematic colour, which warns potential predators of its unpleasant taste. In fact, like many other bugs, it has glands on the sides of its thorax that exude a repulsive-smelling liquid when held. On the red background, 6 longitudinal black bands run across the head, thorax and abdomen. The sides of the abdomen ( connexivum ) are red with many small black spots, with a checkered pattern. The ventral part of the abdomen is dotted. The tarsi have 3 segments and the legs are generally black (red in the typical subspecies lineatum ), except for the third tibia, which can be reddish. They have a pair of black antennae composed of 5 antennae or segments and prominent eyes. Sexual dimorphism consists of females showing a median suture on the eighth abdominal segment, not present in males.

15-3-2017 GANDIA RIO SERPIS, VALENCIA - WHITE WAGTAIL (Motacilla alba)
%2020.jpg)
The White wagtail is a slender bird with the characteristic long, constantly wagging tail of its genus. There are a number of other subspecies, some of which may have arisen because of partial geographical isolation, such as the resident British and Irish form, the pied wagtail M. a. yarrellii, which now also breeds in adjacent areas of the neighbouring European mainland. The Pied wagtail exchanges the grey colour of the nominate form with black (or very dark grey in females), but is otherwise identical in its behaviour. Other subspecies, the validity of some of which is questionable, differ in the colour of the wings, back, and head, or other features. Some rraces show sexual dimorphism during the breeding season. As many as six subspecies may be present in the wintering ground in India or Southeast Asia and here they can be difficult to distinguish.
White wagtails breed throughout Eurasia, only being absent in the Arctic. They also breed in the mountains of Morocco and western Alaska. These birds are residents in the milder parts of their range such as western Europe and the Mediterranean, but migratory in much of the rest of their range. Northern European breeders winter around the Mediterranean and in tropical and subtropical Africa, and Asiatic birds move to the Middle East, India, and Southeast Asia. Birds from the North American population also winter in tropical Asia. White wagtails occupy a wide range of habitats but are absent from deserts. They inhabit grasslands, seashores, rocky shorelines, sand beaches, tidepools, rivers, lakeshores, farmland, gardens, and parks. They are also often found in towns and villages.

14-4-2018 CHOBE RIVER, NAMIBIA - HIPPOPOTAMUS (Hippopotamus amphibius)
The hippopotamus (Hippopotamus amphibius) (/ˌhɪpəˈpɒtəməs/; pl.: hippopotamuses; often shortened to hippo (pl.: hippos), further qualified as the common hippopotamus, Nile hippopotamus and river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis). Its name comes from the ancient Greek for "river horse" (ἱπποπόταμος).
After elephants and rhinoceroses, the hippopotamus is the next largest land mammal. It is also the largest extant land artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from which they diverged about 55 million years ago. Hippos are recognisable for their barrel-shaped torsos, wide-opening mouths with large canine tusks, nearly hairless bodies, pillar-like legs, and large size: adults average 1,500 kg (3,300 lb) for bulls (males) and 1,300 kg (2,900 lb) for cows (females).
Hippos inhabit rivers, lakes, and mangrove swamps. Territorial bulls each preside over a stretch of water and a group of five to thirty cows and calves. Mating and birth both occur in the water. During the day, hippos remain cool by staying in water or mud, emerging at dusk to graze on grasses. While hippos rest near each other in the water, grazing is a solitary activity and hippos typically do not display territorial behaviour on land. Hippos are among the most dangerous animals in the world due to their aggressive and unpredictable nature. They are threatened by habitat loss and poaching for their meat and ivory (canine teeth).
