    Now we are moving to a small but vey charismatic family: The hippos. I think this is an animals that is loved by the majority. Looking at its massive size combined with its features is understandable why. 

    However don’t get mistaken. This animal is a fierce and the one to blame for the most fatalities in Africa. it is a very territorial animal that won’t hesitate to charge if threatened or feeling its territory invaded. The biggest problem with humans happens usually at nights, when the animal leaves the rivers to graze moving various kilometers away from river basins, encountering unaware humans. Running it’s the only option but not a sure escape since despite its weight, hippos can reach up to 50km/h. 

    Hippos depends on rivers because it’s skin, which is actually pink, cannot resist the sunlight and will dry fast. And despite living its majority of time in water, they are unable to swim. 

    5 subspecies have been named but just three are recognized nowadays and they are still subjected to changes. 

    Male hippos fights are barbaric and they mostly happen to get the best spot in the river which will attract the most females. Once a male is dethrone, the new king won’t hesitate on killing the offspring of the old king in order to began leaving its own genes. 

    Hippos in Colombia? Unfortunately, yes. Not because I don’t like them (I’m Colombian) but because they have become a threat to other endemic species of the country. Hippos were brought to Colombia illegally by narco’s most famous Pablo Escobar and were put in its private zoo. When he was killed, the zoo closed but the hippos and some other animals were left in the area. While some animals died, the hippos however, flourished. Today, they occupied a vast area of the country and they begin to clash with other animals such as the inoffensive manatees. 

    While they yet don’t represent a threat to humans (some attacks have been registered) because they are not as territorial as in Africa. (It is believe because they have a larger area to develop) if the quantity keeps growing, they will become as dangerous as in Africa. For now, people greeted in towns because of its natural charm and can become touristic attraction. There are some possible solutions to this issue. One will be to sterilize all males, which is kind of unthinkable because of how expensive this could be. Other will be to send them to various zoos around the world, which is still not enough and  the last one will be to kill them all. I have an opinion about it but I would love to hear yours.

    New design, Better Illustrations! I was thinking for a while in a way to improve the layout of this blog and I feel that this way is much better. I think the layout should highlight the drawings so I decided to remove many other elements that somehow stole its attention. Let me know your thoughts in the comments.

    Thanks again for your support, likes, reblog and follows, means a lot. If you like this content it will help me a lot if you follow my Tumblr or if you share it.

    [Species] | African spoobill

    The African spoonbill (Platalea alba) is a long-legged wading bird and member of the threskiornithidae. As their name suggests, these birds occur within the African continent, incluidng Botswana, Kenya, Monzambique, Namibia, South Africa and Zimbabwe, as well as Madagascar.

    On average individuals can reach a height of 90 centimetres, and weigh up to 1.5 kilograms. The most unique feature of these birds is their spoon-shaped bill, which after hatching doesn’t have its unique shape yet. They’re entirely white, the exceptions being their red face and legs as well as the multicoloured bill.

    Typically, African spoonbills frequent shallow innland waters. Habitats they can be found in include river banks, lake shores, marshes, plains, savannas, swamps and water-meadows. African spoobills do not commonly occur in urban regions, as they are very shy towards humans, and will fly off when they see one.

    Their diet consists of various kinds of fish, molluscs, amphibians, crustaceans, insects and larvae. They, like other spoonills, detect their prey mostly by touch, and only partially by sight. To forage, an individual swings its open bill from side-to-side through the water, closing it shut when they detect a possible prey item.

    Breeding season varies slightly across their range, but always begins in winter and lasts until the spring. Inbetween April and May the female can lay up to five eggs, which both parents icubate for a period of usally no more than 29 days. Both parents continue to care for their nestlings after they hatch, for a period of roughly 20 to 30 days, which is about when the chicks are ready to leave the nest.

    Their populations appear to be stable or only slightly in decline across most of their range, and they’re considered locally common. As a result of this, the IUCN evaluates that African spoobills are a species of least concern, despite suffering some habitat loss here and there.

    I hope it’s ok if I share one of the coolest facts I learnt during my zoology course. Did you know that species that show little sexual dimorphism (i.e. the sexes look the same) are more likely to be monogamous. For example, swans? famously monogamous for life.

    Mallard ducks however, are polygamous. They choose a different mate each season. 

    Sexual dimorphism happens when one sex becomes stronger (or more colourful) in order to outcompete others of that sex for mates. If the couple is monogamous, they don’t have to worry about sexual competition.

    So FYI, humans are sexually dimorphic. amab people *generally* grow to be larger than afab people. This suggests that, evolutionarily speaking, humans aren’t meant to be monogamous. To be clear, evolution is fluid ever-changing. Using ‘biology’ like set-in-stone rules for life is stupid. 

    However, conservatives will say shit like ‘Men and WomenTM are biologically different, that’s just science’ and in the same breath say ‘If you sleep around you’re a slut, don’t have sex till marriage. Also marriage is the end goal for all people.’ Don’t get it twisted yall, ‘biologically’ speaking, these two sentiments are completely contradictory.

    [Species] | Scarlet ibis

    The scarlet ibis (Eudocimus ruber) is a member of the threskiornithidae, occuring in the costal regions of the Americas. They are so closely related to the American white ibis, that scientists sometimes have troubles determining whether or not the two are seperate species, since the only actual difference between them seems to be in their plumage colouration.

    Scarlet ibises reach lengths of inbewtween 55 and 63 centimetres, have an average wingspan of 54 centimetres and max out in terms of weight at 1.6 kilograms. The most memorable feature about these birds is their bright red plumage, which is something the birds grow into over time, with juveniles and chicks being dark grey or black in colour.

    These birds inhabit a vareity of habitats near the shoreline, specifically wetlands. Areas they occur in most commonly can include, but are not limited to, mud flats, mangroves, marshes and rainforests. Individuals also have been spotted gathering near fresh and salt water estuaries. 

    They use their distinctive long, thin bills to probe for food in soft mud or under vegetation. For a long time it was believed that their diet almost entirely consisted of shrimps, but recent studies have shown that they also feed on other crustaceans, mollusks, fish, insects, frogs and sometimes even small snakes to greater extents than previously assumed.

    After mating, the gestation period lasts about five to six days, and after that the females lays a clutch of three to five smooth matte eggs. The incubation period for those is a minimum of 19 days, and usually takes no longer than 23 days. After that, both parents share the responsibilities they have for the young.

    This species has been given a protected status throughout the world and the IUCN (International Union for Conservation of Nature) has classified them as one of least concern. The global populations seem to be stable, but some local populations in places like Brazil or French Guiana are heavily declining.

    Video by PBS Eons: When Rodents Had Horns:

    These odd rodents belong to a genus known as Ceratogaulus, but they’re more commonly called horned gophers, because, you guessed it, they had horns. And it turns out the horns probably had a purpose - one that rodents would likely benefit from today.
