You’ve probably heard of symbiosis (Greek for ‘living together’), a close and long-term association between two different organisms. Endosymbiosis occurs when one organism, known as the endosymbiont, lives inside another, the host. Generally, endosymbionts are small enough to reside within host cells but they aren’t parasites. The interaction between any two species can range from parasitism – where one organism exploits a (usually larger) one to the point of being harmful – to mutualism, in which the association is beneficial to both partners. Unlike parasitic associations, endosymbiotic relationships typically aren’t one-sided.

Jump Around - Bagheera Kiplingi - The acrobatic spider with a predilection for veggie food
Spiders eat flies, right? everyone knows that the 45,000 or so spiders in the world are all obligate carnivores, more or less – eating other animals, mainly invertebrates. Nature, however, loves an exception, and one particular spider missed out on that ecological memo. It goes by the wonderful scientific name of Bagheera kiplingi, and its claim to fame is that its diet is – at least mostly – vegetarian.
Female of the Species - Zebras - A strong sisterhood is key to staying safe
Zebras are masters of confusion. Their collective noun is ‘a dazzle’, which is fitting since their bodies and behaviour have been surprising scientists for centuries.
See It, Save It? - Wildlife tourism can be a powerful ally in protecting nature - but it can also harm it. We weigh up the pros and cons.
The sums of wildlife travel aren’t as simple as more tourists equals happier nature. How much did my visit really contribute to the conservation of Lady Liuwa and her habitat – and was that outweighed by carbon emissions from my flights? Did my presence disturb the animals’ natural behaviour more than it reduced the threat of poaching or benefited local communities?The question of whether wildlife travel is, on balance, good for wildlife is a complex one – and there’s no simple answer.
