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.

Gaebul (Urechis unicinctus) aka penis fish

Urechis unicinctus (Korean: gaebul) is a species of marine spoon worm. It is widely referred to as the fat innkeeper worm or the penis fish.


U. unicinctus, like other Urechis, lives in burrows in sand and mud. It gets the name “fat innkeeper worm” because the tunnels it creates often contain other animals.

In Chinese cuisine the worm is stir-fried with vegetables, or dried and powdered to be used as an umami enhancer. In particular, the worm is considered an important ingredient in Shandong cuisine and is used in numerous recipes.

In addition to its close looks to a part of the male anatomy, it is known for its aphrodisiac effects.

Phacellophora camtschatica – egg yolk jellyfish

Fried Egg Jellyfish (Phacellophora camtschatica) – this jellyfish is also known as Egg yolk jelly.

Phacellophora camtschatica - egg yolk jelly

This jellyfish looks like a fried egg as seen from above. This cool-water species can be found in many parts of the world’s oceans. The diet of Fried egg jellyfish is a small fish and small crabs.

Phacellophora camtschatica - egg yolk jellyfish

Fried egg jellyfish the size is about 60 cm (24 inches) in diameter. The tentacles can be up to 6 m (20 ft) long. The color of a fried egg jellyfish is a yellow spot in the big bell-like shape.

Spends much the time motionless or slowly pulsing the bell while drifting with tentacles extended 10-20 feet or more. Feeds on gelatinous zooplankton, especially other medusae.

The colored portion of the body under the transparent swimming bell consists of the gonads, stomach and the oral arms surrounding the mouth. Reproduction is complicated, involving egg and sperm production by the swimming adult or medusa resulting in a planulae larva that seeks a sheltered home. After attachment it grows for a while forming a polyp which then buds off small medusa. In the laboratory it took about 9 months for an ephyra to grow into a mature medusa.

The tentacles, which hang down some 10 to 20 ft, contain stinging cells (nematocysts). They use the stinging cells to capture prey such as shrimp and fish (Lion’s mane) or other medusa (Fried egg jelly). While the Fried egg jelly’s sting is described as a mild, the Lion’s mane sting can be quite painful.

A smaller jellyfish, Cotylorhiza tuberculata, typically found in warmer water, particularly in the Mediterranean Sea, is also popularly called a fried egg jellyfish.

Mediterranean “fried egg” jellyfish

Cotylorhiza tuberculata is a species of jellyfish, also known as the Mediterranean jelly or fried egg jellyfish. It is commonly found in the Mediterranean Sea, Aegean Sea and Adriatic Sea.

cotylorhiza tuberculata

C. tuberculata is usually less than 17 cm wide. The smooth, elevated dome is surrounded by a gutter-like ring. The marginal lappets are elongated and subrectangular. Each mouth-arm bifurcates near its base and branches several times. In addition to some larger appendages there are many short, club-shaped ones that bear disk-like ends.

The unusual looking Mediterranean jelly, also known as the “fried egg” jelly, has a smooth, elevated bell surrounded by a ring. It has numerous short, clublike appendages that expand and flatten at the ends, in addition to some longer ones. The clustered appendages contain mouth-arm openings that are colored deep purple.

This jelly only lives for about half a year, from summer to winter. Researchers think this short life span is the result of adapting to a highly seasonal environment where the water temperature varies greatly.

Photographer Barry Bland came across one of the free-swimming marine animal – and was thrilled to find that it looked just like a fried egg.

The jellyfish lives in warmer waters as it needs a lot of sunlight to survive. With bright blue balls of colour speckling its umbrella-shaped bell, the eye-catching sea creature alternated between resembling a decorative lamp and a welcome addition to a fry-up.

The Mediterranean Sea is one of the more common areas they’re found, as well as the Aegean and Adriatic seas, given their need for a large concentration of sunlight to survive.

And while they’re stunning to look at, they’re also considerably safer to be around than their counterparts, as their sting has very little or no effect on humans.

Female octopus

The real octomom: Scientists find record-breaking octopus that stayed with her eggs for over four YEARS.
Researchers at the Monterey Bay Aquarium Research Institute (MBARI) have observed a deep-sea octopus brooding its eggs for four and one half years—longer than any other known animal. Throughout this time, the female octopus, a species known as Graneledone boreopacifica, kept the eggs clean and guarded them from predators – even though she gradually lost weight and her skin became loose and pale.

Graneledone boreopacifica produces hatchlings that are very highly developed, which gives them the advantage of a high potential for survival.

This research suggests that, in addition to setting records for the longest brooding time of any animal, Graneledone boreopacifica may be one of the longest lived cephalopods (a group that includes octopuses, squids, and their relatives).
Most shallow-water octopuses and squids live just a year or two.

As the years passed, her translucent eggs grew larger and the researchers could see young octopuses developing inside. Because the young octopus spend so much time in their eggs, by the time they hatch they are fully capable of surviving on their own and hunting for small prey. In fact, the newborns of G. boreopacifica are larger and better developed than the hatchlings of any other octopus or squid.

The pigbutt worm or flying buttocks (Chaetopterus pugaporcinus)

A Worm That Resembles a Disembodied Butt

This disembodied rump is a tiny worm known as Chaetopterus pugaporcinus. In 2006, researchers from the Monterey Bay Aquarium discovered this species bobbing along 3,000 feet deep under the Pacific Ocean. MBARI biologist Karen Osborn and her co-workers recently discovered a new species of deep-sea worm, but a worm like no other. The worm is round in shape, approximately the size of a hazelnut, and bears a strong resemblance to a disembodied pair of buttocks. Because of this, it was given a Latin species name Chaetopterus pugaporcinus that roughly translates to “resembling a pig’s rear.” Upon discovery, this worm earned some profoundly unfortunate monikers, such as “pigbutt worm” and “flying buttocks.”

Chaetopterus pugaporcinus flying buttocks

What appears to be the bull’s-eye at the center of the butthole is where the creature’s mouth is located. In order to feed, said mouth is surrounded by a “cloud of mucus” that catches organic detritus known as marine snow.
As far as their appearance goes, researchers at the aquarium offered up this explanation: “… researchers found that although the worms had segmented bodies, one of their middle segments was inflated like a balloon, giving the animals a distinctive gumball shape. All the other segments were compressed up against the front and back of the inflated segment, like a cartoon character whose nose and hind parts have been flattened in an unfortunate accident.”

This photograph shows the back of the newly named worm. The concentric ovals are body segments that have been flattened against a single central segment that has ballooned out to form the bulk of the worm’s body.

The researchers still aren’t sure if the worms they have been studying are larvae or adults. None of the individuals they collected had any identifiable sex organs, eggs, or sperm. Thus, they could be, as the authors put it, “wayward larvae, swept off the continental shelf and unable to settle [to the seafloor], thus growing to unusual size and developing adult features.”

Chaetopterid polychaetes, distinctive members of nearly all benthic marine communities, have larvae that may spend months in the plankton before settling to live their adult lives in parchment-like tubes attached to the sea floor. The cover image shows an extraordinary new species, Chaetopterus pugaporcinus, that may have relinquished the benthic portion of its life and made itself permanently at home in the pelagic realm. Chaetopterus pugaporcinus possesses the same combination of larval and adult features regardless of the size of the specimen (1 to 2 cm), and it has lost features associated with benthic life that were previously thought to be characteristic of the family. The species is reliably found off the coast of California at about 1000 m, regardless of the seafloor depth. One of its 15 segments is greatly expanded, while the others are compressed to the anterior and posterior poles of the decidedly non-vermiform body.
On pages 40-54 of this issue, Osborn et al. describe this new species and its ecology.

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.
