Acorn worms

The Acorn worms or Enteropneusta are a hemichordate class of invertebrates consisting of one order of the same name. They are closely related to the echinoderms. There are about 90 species of acorn worm in the world. Most acorn worms range from 9 to 45 centimetres in length, with the largest species, Balanoglossus gigas, reaching 1.5 metres (5 ft) or more. The body is made up of three main parts: an acorn-shaped proboscis, a short fleshy collar that lies behind it, and a long, worm-like trunk.

Acorn worms (Hemichordata, Enteropneusta) are more closely related to starfish and sea cucumbers than to other worms and are best known for their acorn-shaped front ends.

Acorn worms are rarely seen by humans because of their lifestyle. They live in U-shaped burrows on the sea-bed, from the shoreline down to a depth of 10,000 ft. (3,050 m). The worms lie there with the proboscis sticking out of one opening in the burrow. Until 1965, it was believed that acorn worms lived only in shallow waters. However, recent work using deep-sea vehicles in conjunction with DNA sequencing has uncovered a wide diversity of vividly colored deep-sea acorn worms, belonging to a new family, which was named Torquaratoridae in 2005.

In 2011, a research team from the P. P. Shirshov Institute of Oceanology recovered a near-complete specimen of a torquaratorid from the floor of the Kara Sea, north of Siberia. Although the specimen was found nearly a mile shallower than any previously known torquaratorid, it turned out to be yet another undescribed member of this family and was recently named Coleodesmium karaensis. This new species is the first acorn worm known to brood its young. Brood pockets consist of a thin membrane on the surface of the mother’s body and each contains a single embryo. Approximately one dozen embryos at various stages of development were identified from the single adult female worm found.

Glossobalanus sarniensis is an acorn worm, belonging to a group of hemichordates called Enteropneusta. They are considered to be intermediary between invertebrates and vertebrates. They have soft, fragile and worm-like bodies and live buried in sand. They are filter-feeders, have an acorn-like proboscis and they breathe by means of gills.

Earliest enteropneust (acorn worm) fossil found, 500 million years old. Fossils of these soft-bodied acorn worms were found in mud dated back to the Cambrian period, placing them a further 200 million years back in time than previously thought.
Christopher Cameron of the University of Montreal’s Department of Biological Sciences and his colleagues have unearthed a major scientific discovery – a strange phallus-shaped creature they found in Canada’s Burgess Shale fossil beds, located in Yoho National Park. The fossils were found in an area of shale beds that are 505 million years old.

Breadfruit penis

Breadfruit (Artocarpus altilis) is a species of flowering tree in the mulberry family, Moraceae, growing throughout Southeast Asia, South India and most Pacific Ocean islands. It is also grown in the Leeward Islands and Windward Islands of the Caribbean and in Africa. Its name is derived from the texture of the cooked moderately ripe fruit, which has a potato-like flavor, similar to freshly baked bread.

Breadfruit trees grow to a height of 25 m (82 ft). The large and thick leaves are deeply cut into pinnate lobes. All parts of the tree yield latex, a milky juice. Breadfruit is one of the highest-yielding food plants, with a single tree producing up to 200 or more grapefruit-sized fruits per season. In the South Pacific, the trees yield 50 to 150 fruits per year. In southern India, normal production is 150 to 200 fruits annually.

Breadfruit is a staple food in many tropical regions. The trees were propagated far outside their native range by Polynesian voyagers who transported root cuttings and air-layered plants over long ocean distances. Breadfruit are very rich in starch, and before being eaten, they are roasted, baked, fried or boiled. When cooked, the taste of moderately ripe breadfruit is described as potato-like, or similar to freshly baked bread. Very ripe breadfruit becomes sweet, as the starch converts to sugar.

Love Valley in Turkey’s Cappadocia region

Love Valley near Goreme, Turkey is famous for its bizarre ‘fairy chimney’ rocks cut naturally by the wind and rain. Göreme located among the “fairy chimney” rock formations, is a town in Cappadocia, a historical region of Turkey. It is in the Nevşehir Province in Central Anatolia and has a population of around 2,500 people.

Although the rocks may make people smirk, they are simply the result of ancient volcanic eruptions, approximately 9 to 3 million years ago during the late Miocene to Pliocene epochs, which covered the region with thick ash that solidified into soft rock many metres thick.

Erosion from the wind and water left only its harder elements behind, forming an unusual landscape of cones, pillars, pinnacles, mushrooms, and ‘fairy tale chimneys’, some of which are up to 130 feet (40 metres) high.

The huge phallic formations may look like a homage to male fertility, but they have been naturally formed by erosion of the volcanic rock.

The famous region of Cappadocia has seen an influx of tourists travelling by hot air balloon to check out the phallic-shaped pillars, which have been dubbed by some travellers, the ‘c*ck rocks’.
Every morning before sunrise, hundreds of hot air balloons rise into the air above Cappadocia, each holding around a dozen passengers for dawn-time hot air balloon travel, floating above and around the beautiful rock formations that has also jokingly been referred to as ‘willy valley’.

Halomonas titanicae – bacteria from The Titanic

Halomonas titanicae is a species of bacteria which was found on rusticles in the wreck of the RMS Titanic, at the bottom of the sea. Dr Henrietta Mann discovered the bacteria when analysing rusticle samples taken from the Titanic in 1991.

The bacterium, named Halomonas titanicae, sticks to steel surfaces, corroding them.

The bacteria has been listed as potentially dangerous to oil rigs and man-made objects in the deep sea, although an advantage to Halomonas titanicae’s discovery is that old ships that litter the sea floor will be recycled by this bacterium.

Amaranthus dick

Amaranthus, collectively known as amaranth, is a cosmopolitan genus of annual or short-lived perennial plants.

amananthus penis-shaped flower

Known to the Aztecs as huauhtli, it is thought to have represented up to 80% of their caloric consumption before the conquest. Another important use of amaranth throughout Mesoamerica was to prepare ritual drinks and foods.

amananthus penis-shaped flower

Because of its importance as a symbol of indigenous culture, its gluten-free palatability, ease of cooking, and a protein that is particularly well-suited to human nutritional needs, interest in grain amaranth revived in the 1970s. It was recovered in Mexico from wild varieties and is now commercially cultivated. It is a popular snack sold in Mexico, sometimes mixed with chocolate or puffed rice, and its use has spread to Europe and parts of North America.

Although several species are often considered weeds, people around the world value amaranths as leaf vegetables, cereals, and ornamental plants. The root of mature amaranth is a popular vegetable. It is white and cooked with tomatoes or tamarind gravy. It has a milky taste and is alkaline. In China, the leaves and stems are used as a stir-fry vegetable, or in soups. A traditional food plant in Africa, amaranth has the potential to improve nutrition.

Amaranth greens are a common leaf vegetable throughout the tropics and in many warm temperate regions. Amaranth seeds contain lysine, an essential amino acid, limited in other grains or plant sources. Amaranth may be a promising source of protein to those who are gluten sensitive, because unlike the protein found in grains such as wheat and rye, its protein does not contain gluten.

The Proboscis monkey of Borneo

The proboscis monkey (Nasalis larvatus) or long-nosed monkey is a reddish-brown arboreal Old World monkey that is endemic to the south-east Asian island of Borneo.

This species of monkey is easily identifiable because of its unusually large nose.
Actually, proboscis monkeys have the longest noses of all primates. Although females already have a very large nose for a primate, the nose of males is so long it often hangs over their mouth, exceeding 10cm in length. In elderly animals, it can reach 17.5cm (a quarter of the body length). Although its function is not known for sure, it is likely to be a visual signal used in mate choice. The male vocalises through the nose with a kee honk sound.

With their large pendulous nose, giant bellies, and permanent erect penis, the proboscis monkey has one of the most unusual appearances of all primates.

Proboscis monkeys feed on leaves, seeds, fruits, flowers and a very small proportion of animal prey.

Proboscis monkeys eat fruits and leaves, and in one area regurgitate and chew that cud again.

The monkey also goes by the Malay name monyet belanda (“Dutch monkey”), or even orang belanda (“Dutchman”), as Indonesians remarked that the Dutch colonisers often had similarly large bellies and noses.

sexy Proboscis monkey

Proboscis monkeys can only be found in Borneo and inhabit mangrove, peat swamp, and riverine forests. Although they are mostly arboreal (tree-living), proboscis monkeys are good swimmers and have the most aquatic lifestyle among primates. They usually live in a harem which comprises one adult male and one to eight females and their offspring. The males are much larger, weigh more than twice as much as females, and have an erect penis almost permanently.

sexy Proboscis monkey

Another striking characteristic of Proboscis monkeys are their large pot bellies, making them look permanently pregnant. Their bellies are so enourmous because of a very special digestive system which consists of cellulose digesting bacteria, enabling them to eat leaves and unripe fruit. Their stomach is so large, its contents can make up to one quarter of their body weight.

Proboscis monkeys generally live in groups composed of one adult male, some adult females and their offspring. All-male groups may also exist. Some individuals are solitary, mostly males.

The only fruit proboscis monkeys will eat is unripe fruit. The sugars in ripe fruits can ferment in their stomachs and cause fatal bloating.

Banana slug

Banana slug is a common name for three North American species of terrestrial slug in the genus Ariolimax. These slugs are often yellow in color and are sometimes spotted with brown, like a ripe (or overripe) banana. Individual slugs will change colors with alterations in food consumption, light exposure, and moisture levels. Color may also indicate whether a slug is healthy, injured, or what age they are.

large banana slug

Slugs use two pairs of tentacles to sense their environment. The larger, upper pair, termed “eyestalks,” are used to detect light or movement. The second, lower pair are used to detect chemicals. The tentacles can retract and extend themselves to avoid damage. If a predator bites off a tentacle, the slug can grow a new one.
Banana slugs are detritivores, or decomposers. They process leaves, animal droppings, and dead plant material, and then recycle them into soil humus.

The slime also contains pheromones to attract other slugs for mating. Slugs are simultaneous hermaphrodites, and reproduce by exchanging sperm with their mate. They produce up to 75 translucent eggs, which are laid in a log or on leaves. Slugs mate and lay eggs throughout the year. The adults provide no further care for their eggs beyond finding a suitable hiding spot.

Banana slugs have small teeth that are on its tongue. It uses this toothy tongue (radula) like a file so it can eat its food. Individuals can move at 6 1⁄2 inches (17 cm) per minute.

Banana slugs have been used as food by Yurok Indians of the North Coast and by German immigrants in the 19th and early 20th centuries. A yearly festival and contest is held at Russian River (California) including slug races and a contest for recipes – though, even when fed corn meal to purge them or soaked in vinegar to remove slime, the slugs’ flavor is not always well regarded, and the most successful entries are often those in which the flavor is unnoticeable.
