Spectacled bears are the only surviving species of bear native to South America, and the only surviving member of the subfamily Tremarctinae, the short-faced bears. Their range is the Andean Mountains from Venezuela to Chile. [1]
Although there are many fossil species, the only species surviving today is the aardvark, Orycteropus afer. Orycteropodidae is recognized as the only family within the order Tubulidentata, from the Latin words tubulis (tubule) and dentis (tooth), referring to the tubule-style teeth. [3], so the two are effectively synonyms. [1] [4]
They are the only surviving members of the family Elephantidae and the order Proboscidea; extinct relatives include mammoths and mastodons. Distinctive features of elephants include a long proboscis called a trunk, tusks , large ear flaps, pillar-like legs, and tough but sensitive grey skin.
The three orangutan species are the only extant members of the subfamily Ponginae. This subfamily also includes extinct apes such as Lufengpithecus , which occurred 8–2 mya in southern China and Thailand; [ 20 ] : 50 Indopithecus , which lived in India from 9.2 to 8.6 mya; and Sivapithecus , which lived in India and Pakistan from 12.5 mya ...
Requiem for a Species: Why We Resist the Truth about Climate Change is a 2010 non-fiction book by Australian academic Clive Hamilton which explores climate change denial and its implications. It argues that climate change will bring about large-scale, harmful consequences for habitability for life on Earth including humans, which it is too late ...
A survivorship curve is a graph showing the number or proportion of individuals surviving to each age for a given species or group (e.g. males or females). Survivorship curves can be constructed for a given cohort (a group of individuals of roughly the same age) based on a life table .
Insects make up the vast majority of animal species. [14]Chapman, 2005 and 2009 [9] has attempted to compile perhaps the most comprehensive recent statistics on numbers of extant species, drawing on a range of published and unpublished sources, and has come up with a figure of approximately 1.9 million estimated described taxa, as against possibly a total of between 11 and 12 million ...
Elephantidae is a family of large, herbivorous proboscidean mammals which includes the living elephants (belonging to the genera Elephas and Loxodonta), as well as a number of extinct genera like Mammuthus (mammoths) and Palaeoloxodon.
