Interesting and nice - thanks for posting.
How dangerous are mosquito bites in this location? Here in Sweden they are common, annoying but harmles.
Best regards

Thanks JH, Beatsy and Mawyatt for the kind words.
JH - Malaria is endemic to Africa, not to mention filariasis and bunch of other vector borne pathogens, including the tse-tse fly communicated African sleeping sickness.
Beatsy - This particular national park is in the cloud forest and so quite cool compared to the lowlands. Temperature is often inversely proportional to diversity, and so I didn't find quite as much as I would have in the lowlands.
Mawyatt - Indeed it was!

Wonderful pictures, as always!
But what particularly caught my attention this time was a bit of the language.
Paul wrote "Malaria is endemic to Africa".
That prompted some confusion inside my head, so I looked up the official definition of "endemic".
According to Google search on "define endemic"
Malaria as a disease is endemic in Africa (because it's regularly found there), but the malaria parasite is not endemic to Africa because it is also found in Asia and Latin America.
I am a native English speaker, but sometimes this language vexes me!

In other words, the word "endemic" means two very different things, depending on whether you're talking about a disease or an organism.adjective
1. (of a disease or condition) regularly found among particular people or in a certain area.
"areas where malaria is endemic"
2. (of a plant or animal) native or restricted to a certain country or area.
"a marsupial endemic to northeastern Australia"

Meanings can be vexing indeed. And then there's pronunciation - http://www.i18nguy.com/chaos.htmlrjlittlefield wrote: I am a native English speaker, but sometimes this language vexes me!
Perhaps doubly challenging for Muricans. "Aluminum"!? "Tomaydo"!? How quaint!
Different fields (Ecology vs Epidemiology) different meaning, although related. Not just English but a general issue.rjlittlefield wrote:...

What about objective, for example?

I was very surprised the first time I saw a hairy snail shell. In Europe we have a fairly common and widespread hairy snail. But very few besides the specialists are aware of it beceause of its small size (no more than 6 mm).Lou Jost wrote:I especially liked the katydid, and the hairy-shelled snail. I don't recall ever seeing such a snail.

And I love the pictures from the rainforest.
