Species of the Day: Lion's Mane Jellyfish (Cyanea capillata)

The Lion's Mane jellyfish is a sea creature found predominantly in the icy north pacific, arctic and north atlantic oceans. Cyanea capillata is the world's largest jellyfish. The largest on record was found in Massachusetts Bay in 1870. That individual was larger than 7ft (2.1M) across the bell with tentacles greater than 120ft (36.5M) in length! Because of this length, Cyanea capillata is amongst the longest of all living organisms, being in competition with the Bootlace worm and the Blue Whale.

These animals are important ecologically as they act islands in the open ocean. As the Cyanea capillata floats in frosty, calm bays, many other sea creatures cluster around them, as the jellyfish provides food and shelter.

The Lion's Mane jellyfish is fed on by many large fish, seabirds and some turtles. The Leatherback Sea turtle lives almost exclusively off Cyanea capillata, travelling far and wide to reach the coasts of Eastern Canada to feed in Summer months.

Despite their massive size, the Lion's Mane jellyfish is not dangerous to humans as their sting merely causes discomfort.

Paul Nicklen's encounter with a Leopard Seal (Hydrurga leptonyx)

Check out this awesome video about Paul Nicklen who is a National Geographic photographer. This video shows his efforts to get photos of a leopard seal. The Leopard seal is a notorious apex predator which can be quite dangerous. However as this video demonstrates, the Leopard seal may also be misunderstood. Watch this short clip to see some incredible footage:

Species of the Day: Corpse Flower (Amorphophallus titanum)

Amorphophallus titanum (meaning "misshapen phallus titan") is a massive flower and is in fact the largest unbranched flower in the world. The colloquial name "Corpse Flower" comes from an odour given off by the flower which smells distinctly of decomposing flesh. This rotting smell attracts flies and therefore aids in cross pollination.

This flower grows only in the rain forests of Sumatra and holds the record for tallest flower in the world, having been cultivated to the height of 3.1 M!

Watch this clip from David Attenborough's Private Life of Plants to see the first footage of Amorphophallus titanum pollination ever.

Fruit Hunters (2012)

During my incredibly long flight from Canada to Australia I came across this Canadian documentary called Fruit Hunters, which premiered in 2012. Its an exploration of rare and exotic fruits from around the world. I was amazed by the beauty and diversity of fruit which existed in the world of which I was completely ignorant. This documentary inspired me to start hunting for new fruits myself. Fruit Hunters also makes me want to host a fruit party!!

Watch the documentary here and I guarantee you won't be disappointed!

Species of the Day: Gharial (Gavialis gangeticus)

This fish-eating crocodile is native to the Indian subcontinent and is found nowhere else. It is critically endangered and is undergoing a rapid decline in population. One of three crocodile species native to India, alongside the Mugger Crocodile and Saltwater Crocodile, the Gharial is one of the longer living of all crocodilian species.

(Male Gavialis gangeticus exhibiting his ghara)

Although male Gharial can grow up to 20 ft. (6 M) they are almost never any danger to humans, as they live on nothing but fish, a few frogs and insects. Male Gharial have a bulbous protuberance on the end of their snout, known as a ghara which emerges as they reach sexual maturity. The ghara is used by Gavialis gangeticus to alter his hissing noises as a breeding display. Vocalizations are very important to all crocodilians and they are the most vocal of all reptiles and amphibians other than frogs. The vocalizations of the male Gharial can be heard over a km away making it an essential breeding tool for these nearly extinct fossils. The Gharial's snout is highly specialized for hunting fish as it is so long and thin, filled with 110 razor sharp teeth! No Gharial has ever been recorded to harm humans. The myth that they are dangerous to humans comes from their habit of eating jewellery, however this behaviour aids in buoyancy regulation.

According to IUCN there has been a 96-98% decline in Gharial population since 1946. They have dropped from around 10,000 individuals down to a mere 235 (2006). The population has been stressed due to over-hunting for skins, egg stealing for consumption, slaughter for eastern medicine and culling by competing fishers.

The Gharial is a fascinating and unique species, a remnant of an age gone by. It would truly be a shame if we let this species disappear into non-existence. Check out the Madras Crocodile Bank, which is on the frontline of the fight for Gharial survival!

Here is a BBC clip which shows a clutch of Gharials hatching as well as demonstrates this remarkable species' aptitude for maternal care. Enjoy:

Species of the Day: Lammergeier (Gypaetus barbatus)

The Lammergeier, or Bearded Vulture is a species of vulture found in a vast range of environments. Gypaetus barbatus is found in the Alps of Europe, India, Africa and Tibet. This vulture is distinguished from old world vultures by its feathered neck/head (as opposed to the bald cranial regions typical of vultures). This vulture is usually recognized by its rust red colouration, however, the adult bird is actually mostly white. The rusty colour comes from the behaviour of dust bathing. The Lammergeier is also noted for having bristle-like feathers protruding from below its beak, hence the common english name, Bearded vulture.

The Lammergeier, like most vultures, lives almost exclusively off of carrion. Unlike most vultures, Gypaetus barbatus eats almost nothing but the bones of said carrion. Because the Bearded vulture cannot break large bones into digestible chunks with its beak, the Lammergeier has developed an extraordinary technique of bone destruction.

 The Lammergeier is famous for its habit of picking up heavy bones and flying high above piles of rocks. The vulture then drops the bones from heights of 50-150m onto the rock piles, where bones too large to swallow shatter into more appropriate sizes. The Lammergeier then swoops down and devours the small chunks of bone, absorbing the nutrients in the marrow.  Gypaetus barbatus can feed on bones up to 4kg (almost half its weight!) by using this specialized technique, and this method can take young vultures up to seven years to master. Although bone marrow makes up 85-90% of the Lammergeier's diet, the vulture has also been noted to use this technique on large live animals as well.

Watch the Lammergeier using this bone scavenging technique here:

Species of the Day: Pig-Nosed Turtle (Carettochelys insculpta)

The Pig-Nosed Turtle is a freshwater turtle from northern Australia and New Guinea. The only living member of its genus, Carettochelys insculpta are unique in the world of river turtles. The Pig-Nosed Turtle, or Fly River turtle has fins instead of front feet, making it resemble a marine turtle. Carettochelys insculpta is named for its snout-like nose and front facing nostrils, which allow the turtle to take in air at the waters surface more easily.

The wild population of Pig-Nosed turtles have declined over 50% in the last thirty years for many reasons. Many are smuggled out of Indonesian New Guinea, destined for the exotic pet trade or the wildlife food markets of China.    

The Pig-Nosed turtle is an omnivore, eating fruits, vegetables, molluscs and crustaceans. Like many turtle species, Carettochelys insculpta reaches maturity late in life. Females don't reach breeding age until they are 18+ years old. This species is most remarkable for breeding strategy. They breed during the dry season and lay their eggs in sandy river banks. Remarkably the fully developed babies will not hatch until certain environmental conditions trigger the hatching process, but will rather stay in a hibernation state until ready. The Pig-Nosed turtles will only start to hatch when either the eggs are immersed in water or pressure drops significantly (signalling an approaching storm). This gives the hatchlings several advantages. Being nearly entirely aquatic, the turtles rely on the river for survival. Thus the flood induced hatching ensures the turtles will have a ready food source and also shelter in the environment they are most comfortable in. This strategy also ensures the clutch of eggs all hatch at the same time giving safety in numbers.

The following clip from David Attenborough's Life in Cold Blood illustrates this unique reproductive strategy very eloquently. Enjoy:

Species of the Day: Golden Snub-Nosed Monkey (Rhinopithecus roxellana)

The Golden Snub-Nosed Monkey (Rhinopithecus roxellana) is a small primate endemic to the mountain forests of SW China. While the adults grow luxurious golden coats, the babies are covered in dense white fur.

 Living in frigid regions of the Sichuan province, this monkey lives mostly off of lichens. This species is endangered largely because of habitat loss. Moreover, it is because the Golden Snub-Nosed Monkey relies so heavily on lichen (which grows on trees, living and dead). When dead trees are found in the woods they are harvested by humans, thus removing a key nutritional source of this Chinese primate. 

One of the most adorable behavioural characteristics of this species is their habit of huddling for warmth while they sleep in frosty trees. The Golden Snub-Nosed Monkey lives in one of the coldest environments of a non-human primate. The following clip from Planet Earth illustrates their behaviour nicely:

Species of the Day: Regal Horned Lizard (Phrynosoma solare)

This fascinating lizard is found in the deserts of Mexico and the American Southwest. This spiky predator lives almost solely off of ants. A voracious hunter, the Regal Horned Lizard can consume thousands of ants a day and up to 2500 in a single sitting. This small lizard burrows deep in the winter to escape the cold days while it spends summer days hunting in the heat. 

To warm up in the morning the Regal Horned Lizard buries itself neck deep in the sand and circulates all its bodies blood through its head into a sack behind the eyes. The horned lizards cold blood then warms up in the head, from where it is recirculated to the rest of the body. This way the Regal Horned Lizard can warm up its body without exposing more than its heavily armoured head. 

Phrynosoma solare also uses the blood sacks behind its eyes for one of the reptile world's most amazing defence mechanism. When threatened the Regal Horned Lizard shoots blood out of its eyes up to meters away with amazing accuracy. This video (although terribly narrated) demonstrates this ability very well. Enjoy:

Species of the Day: Aye-aye (Daubentonia madagascariensis)

This strange Lemur hails from the kingdom of the Lemurs, Madagascar. Through the age old belief that the Aye-aye is an omen of death, coupled with recent pressures of deforestation this nocturnal lemur faces extinction. This large lemur fills the niche that a woodpecker would in North America and Europe by using it's specially adapted (elongated) third finger to probe inside trees for juicy grubs. This digit is much longer, thinner and more flexible than the other fingers.

(notice the Rodent-like teeth and thin, elongated 3rd digit)

For years no one knew how to classify the Aye-aye and scientists believed this primate was in fact a rodent! This was due to the Aye-aye's odd appearance and in particular it's large front teeth. These teeth are very efficient at demolishing wood. In fact, the Aye-aye has been known to chew through concrete and aluminum. Another distinguishing of this lemur is that it's nipples are located beside the genitals, rather than on the chest or in the armpits like most primates. Between its teeth, digits and nipples, the Aye-aye is a rather odd primate.

This nocturnal creature spends most of it's nights (upwards of 80%) searching for grubs. To find insect larvae in trees the Aye-aye uses it's specialized third digit to tap on trees, listening for hollow cavities and movement within. When prey has been located the Aye-aye chews a hole to expose the cavity and probes inside with it's long 3rd digit. This digit is then used to extract the tasty morsel. Here is a video that shows how the Aye-aye catches it's larval prey:

The Madagascar Fauna Group (MFG) is one of many organizations working to save the many endemic and globally unique species of Madagascar. Check out their website for more information about Lemur and other animal/environmental conservation actions taking place now.
