Alice The Camel

A Bactrian Camel at London Zoo

This is a photo of a Bactrian camel, and a very handsome one too, even if he does have straw all over his face. Bactrian camels are super fluffy and have two humps, while dromedary camels are less fluffy and only have one. Strangely, although there are over two million Bactrian camels alive today, they are listed as critically endangered because most of these camels are domesticated, and only about 800 still live in the wilds of China and Mongolia.

High Speed Sloth

Linnaeus's Two-toed Sloth

It's a Linnaeus's two-toed sloth! The silly thing about two-toed sloths is that they have three toes. They have two fingers. You'd really think biologists would know the difference. It's like the sperm whale all over again, except somewhat less gross.

Sloths are amazing because they're the only living mammal that looks more realistic in CGI than in real life. The way they move is so laboured, it's like every moment they're wondering if they really want to get to where they're going at all. That or they're stop-motion animated.

It's not a particularly exciting photograph, and it wasn't helped by the fact that the rainforest building's accurate recreation of a rainforest environment steamed up both my glasses and my camera. But who cares. Sloths are cool.

Furball

Photograph of a prarie dog at London Zoo

This prarie dog was a tricky character; (s)he kept doing entirely adorable poses in parts of the enclosure that I couldn't get on camera. Outrageous!
And the keeper was most rude when I complained about it. Really, you'd think they'd train the animals to be more photogenic.

FUN FACTS ABOUT PRARIE DOGS:

1. Prarie dogs are rodents, not dogs, as I was surprised to learn aged eleven, having assumed they were America's equivalent of the dingo.*

2. According to Professor Con Slobodchikoff, prarie dogs may have the most sophisticated language of any animal, able to communicate the news of predators approaching as well as describing the colour, type of predator, and the direction it's coming from.

3. Prarie dogs are social creatures and are very affectionate, greeting one another with a prarie dog kiss.

4. Black-tailed prarie dogs live in large communities known as "towns". The largest known prarie dog town covered 25,00 square miles in Texas and was home to perhaps as many as four hundred million prarie dogs.

Diorama of Iguana

Green Iguana at London Zoo

A photo of a Green Iguana at London Zoo. Although this one is extremely and obviously green, apparently these iguanas come in a range of colours, from multicoloured to red. These iguanas are pretty awesome; they have an extra photosensory organ on the top of their heads which is known as the parietal eye. While it's nowhere as developed as their actual eyes, it can detect movement and changes in light and dark, thus helping the iguana to detect predators coming in from above - a useful feature in a tree climbing lizard. Their actual eyes are able to see into ultraviolet wavelengths, so the iguana is easily able to ensure it gets enough UV light to produce sufficient vitamin D.

It's admittedly not an amazing photograph, but it's darn tricky getting a good picture through a scratched glass tank!

Hey Hey We're The Monkeys

Two squirrel monkeys

And we're back to photos of squirrel monkeys! This photograph was taken, as you've already worked out, at London Zoo.

The most famous squirrel monkey of them all was of course Miss Baker, one of the first two animals who were launched into space in 1959 and survived, along with the rhesus monkey Miss Able. She went on to live for twenty five years afterwards, receiving copious amounts of fanmail from children who'd heard of her exploits, and when she died of kidney failure in 1984, over 300 people attended her funeral.

Who knew!

The Miscreant

Escaped Pelican at London Zoo

In my last post, I mentioned that when I visited the Penguin Beach at London Zoo there were two naughty Eastern White Pelicans who sneaked into the penguin enclosure; here's a picture of one of them. Apparently the pond that the pelicans usually live in had frozen over, so they were moved to temporary accomodation next to the penguins, from which they promptly escaped, climbed onto the roof of a shed by the penguin beach, and proceeded to jump over and flap across to the pool.

Various keepers were on hand to herd the mischevious pelicans back to their temporary home, and they were both recaptured fairly quickly! It was highly entertaining though, I must admit.

Funny Looking Penguin

Juvenile Penguin at London Zoo

This photograph is of what I can only describe as a funny looking penguin at London Zoo's Penguin Beach. Penguin Beach contains four species; the rockhopper penguin, blackfooted penguin, humboldt penguin and macaroni penguin. I've looked up  pictures of each of these species, and this penguin looks like none of them. (On the day I visited, Penguin Beach also contained two pelicans who had escaped from their own accomodation and jumped into the penguin pool, but clearly this is not a pelican either.)

So on balance, I suspect this photograph is of a juvenile humboldt or blackfooted penguin, but who knows which! It's tricky to judge before their adult feathers come in. Alas, I obviously make a poor ornithologist. Ho hum! He was an obligingly photogenic fellow, whatever he is, unlike all his friends who were waddling and splashing and zooming around the pool with no thought for the humans vainly trying to get a good shot of them.

Squirrel Monkey

Common Squirrel Monkey

As promised, another squirrel monkey photograph, taken on my recent trip to London Zoo. Whilst I took dozens of photos of the monkeys, it was admittedly tricky to get pictures of them that weren't crazily blurry. They don't like to sit still (probably because in the wild this might result in being eaten).

The Common Squirrel Monkey comes from the Amazon Basin in South America, and lives in the middle canopy of the rainforest. At first, when I saw the monkey in this photo carefully examining and later nibbling his tail I wondered what he was doing, but apparently squirrel monkeys have a habit of smearing food onto their tails, and may smear urine all over themselves as well. A charming habit! I suspect that advertising that particular fact in the squirrel monkey enclosure would actually be more effective at persuading people not to try to touch the monkeys than all the signs warning that they bite.

An interesting fact about squirrel monkeys relates to their colour vision; in these monkeys, one gene on the X chromosome codes for colour vision, and there are three versions of this gene, each of which produces a pigment sensitive to a different wavelength of light. Because male squirrel monkeys have only one X chromosome, they are dichromatic (i.e. any colour which they can see can be created using a mixture of just two pure spectral lights - similar to what we call colour blindness in humans); however, because female squirrel monkeys have two X chromosomes, about two-thirds of them have trichromatic vision like humans (i.e. a mixture of three pure spectral lights is required to create all the colours which they are able to see). Researchers have successfully used gene therapy to give adult male squirrel monkeys trichromatic colour vision.

Welcome to the Jungle

Squirrel monkey at London Zoo

It's a monkey!

This weekend I went to ZSL London Zoo with my boyfriend. We had been meaning to go for about a year, because last year for his birthday present I adopted a squirrel monkey for him from the zoo,* but obviously we had to wait until the coldest weekend in the year. Being a naturally chilly person (both in temperature and personality), I wore eight layers of clothing to ensure I wouldn't get too cold. I was so bundled up I couldn't lift my arms above shoulder-height. But it was worth it!

But anyway, we had an awesome day! It was the first day of half-term, so I had expected it would be pretty busy, but in fact it was fairly quiet - I think the cold kept people at home. It was really nice being able to walk around the zoo without being buffeted by hordes of people. We went to visit my boyfriend's adopted squirrel monkey, Bounty, who lives with his monkey clan in an awesome exhibit which you can walk through. It's highly entertaining to watch them all bouncing around the place, and consequently I have a whole lot of monkey photos which will probably take over this blog for some time! Prepare to learn more than you ever needed to know about squirrel monkeys...
