All rights reserved. A pregnant sperm whale washed up dead on a beach in Sardinia, Italy. Its stomach was full of plastic. When scientists and veterinarians cut open her womb and stomach, they found a horrifying sight: A dead baby whale, and nearly 50 pounds of plastic waste jammed into her belly.

They could also see the remains of some of the squid she'd eaten—but the nutrients from that food likely never made it into her bloodstream, because her intestines were blocked by the morass of plastic waste. The scientists think the foot long whale was part of a pod that spends its time feeding and birthing its babies in the nearby Caprera Canyon, a crevasse deep below the crystalline surface waters of the Mediterranean Sea.

The region is popular with tourists and boaters, and biologists thought the biggest challenge the whales faced were the dangers of boat strikes—not plastic pollution. But under the beautiful surface of the sea, says Bittau, the situation is ugly.

Plastic litters the deep ocean floor, where the sperm whales and their closely related brethren go to eat. They dive deep into the canyon, using echolocation to search for the squid they like to eat.

But a plastic bag waving in the deep ocean currents could be difficult to distinguish from a fluttering squid. And once a whale ingests it, that bag is stuck there. Each mistake a feeding whale makes adds to the problem, and slowly its stomach fills with the deadly material. Veterinarians and scientists at the nearby University of Sassari are still investigating what, exactly, killed it and the baby.

Plastic pollution has penetrated to the deepest crevasses of the ocean , and the Mediterranean is no exception. It collects waste from the countries bordering it, and because the ocean is a closed basin, that waste stays trapped in its waters—essentially forever.

In response to the plastics crisis, the European Union recently passed a ban, scheduled to go into effect in , on many types of single-use plastics. We don't have to worry about changing ocean chemistry or about managing fish population stocks. We just have to turn off the tap of plastics flowing into our waters. Read Caption.

They have small dorsal fins that are low, thick, and usually rounded. December Up to gallons of the liquid wax might be scooped from the head of a large sperm whale. Each species of whale has a distinctive spout and it took an experienced hand to know whether he was seeing a prized sperm whale or a fin whale that the captain might not consider worth pursuing. Instead, the researchers suspect that the whales died because the animals accidentally ventured into shallow seas. Sperm whales can ingest marine debris, as do many marine animals.

Dead sperm whale found in Indonesia had ingested '6kg of plastic' - BBC News

It is the only living member of the genus Physeter and one of three extant species in the sperm whale family , along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia. The sperm whale is a pelagic mammal with a worldwide range, and will migrate seasonally for feeding and breeding.

The females cooperate to protect and nurse their young. A mature sperm whale has few natural predators, although calves and weakened adults are sometimes killed by pods of killer whales orcas. Spermaceti sperm oil , from which the whale derives its name, was a prime target of the whaling industry, and was sought after for use in oil lamps, lubricants, and candles.

Ambergris , a solid waxy waste product sometimes present in its digestive system, is still highly valued as a fixative in perfumes , among other uses. Beachcombers look out for ambergris as flotsam. The species is protected by the International Whaling Commission moratorium, and is listed as vulnerable by the International Union for Conservation of Nature.

The name sperm whale is a truncation of spermaceti whale. Spermaceti , originally mistakenly identified as the whales' semen , is the semi-liquid, waxy substance found within the whale's head see below.

The etymological dictionary of Corominas says the origin is uncertain, but it suggests that it comes from the Vulgar Latin cappula , plural of cappulum , "sword hilt". The sperm whale belongs to the order Cetartiodactyla , [16] [17] [18] [19] [20] the order containing all cetaceans and even-toed ungulates.

It is a member of the unranked clade Cetacea , with all the whales, dolphins, and porpoises, and further classified into Odontoceti , containing all the toothed whales and dolphins. It is the sole extant species of its genus, Physeter , in the family Physeteridae.

Two species of the related extant genus Kogia , the pygmy sperm whale Kogia breviceps and the dwarf sperm whale K. Swedish ichthyologist Peter Artedi described it as Physeter catodon in his work Genera piscium , from the report of a beached specimen in the Orkneys in and two beached in the Netherlands in and The sperm whale is one of the species originally described by Linnaeus in in his 18th century work, Systema Naturae.

He recognised four species in the genus Physeter. Until , the species was generally known as P. In that year, however, Dutch zoologists Antonius M. Husson and Lipke Holthuis proposed that the correct name should be P. This proposition was based on the grounds that the names were synonyms published simultaneously, and, therefore, the ICZN Principle of the First Reviser should apply.

In this instance, it led to the choice of P. The sperm whale is the largest toothed whale, with adult males measuring up to A similar size is reported from a jawbone from the British Natural History Museum.

Extensive whaling may have decreased their size, as males were highly sought, primarily after World War II. The sperm whale's unique body is unlikely to be confused with any other species. The sperm whale's distinctive shape comes from its very large, block-shaped head, which can be one-quarter to one-third of the animal's length.

The S-shaped blowhole is located very close to the front of the head and shifted to the whale's left. The sperm whale's flukes tail lobes are triangular and very thick. Proportionally, they are larger than that of any other cetacean, and are very flexible. The largest ridge was called the 'hump' by whalers, and can be mistaken for a dorsal fin because of its shape and size. The ribs are bound to the spine by flexible cartilage, which allows the ribcage to collapse rather than snap under high pressure.

Bones show the same pitting that signals decompression sickness in humans. This damage may indicate that sperm whales are susceptible to decompression sickness, and sudden surfacing could be lethal to them. Like that of other toothed whales , the skull of the sperm whale is asymmetrical so as to aid echolocation.

Sound waves that strike the whale from different directions will not be channeled in the same way. The sperm whale's lower jaw is very narrow and underslung. One hypothesis is that the teeth are used in aggression between males. Rudimentary teeth are also present in the upper jaw, but these rarely emerge into the mouth. Like the age-rings in a tree, the teeth build distinct layers of cementum and dentine as they grow. The brain is the largest known of any modern or extinct animal, weighing on average about 7.

Elephants and dolphins also have larger brains than humans. The sperm whale's cerebrum is the largest in all mammalia, both in absolute and relative terms.

The olfactory system is reduced, suggesting that the sperm whale has a poor sense of taste and smell. By contrast, the auditory system is enlarged. The pyramidal tract is poorly developed, reflecting the reduction of its limbs. The sperm whale respiratory system has adapted to cope with drastic pressure changes when diving. The flexible ribcage allows lung collapse, reducing nitrogen intake, and metabolism can decrease to conserve oxygen. Sperm whales spout breathe 3—5 times per minute at rest, increasing to 6—7 times per minute after a dive.

The blow is a noisy, single stream that rises up to 2 metres 6. The first secretes no gastric juices and has very thick muscular walls to crush the food since whales cannot chew and resist the claw and sucker attacks of swallowed squid. The second chamber is larger and is where digestion takes place. Undigested squid beaks accumulate in the second chamber — as many as 18, have been found in some dissected specimens.

Such beaks precipitate the formation of ambergris. The diameter of the aortic arch increases as it leaves the heart. This bulbous expansion acts as a windkessel , ensuring a steady blood flow as the heart rate slows during diving. There is no costocervical artery. There is no direct connection between the internal carotid artery and the vessels of the brain.

The oxygenated blood can be directed towards only the brain and other essential organs when oxygen levels deplete. Atop the whale's skull is positioned a large complex of organs filled with a liquid mixture of fats and waxes called spermaceti. The purpose of this complex is to generate powerful and focused clicking sounds, which the sperm whale uses for echolocation and communication. The spermaceti organ is like a large barrel of spermaceti.

Its surrounding wall, known as the case , is extremely tough and fibrous. The case can hold within it up to 1, litres of spermaceti. Below the spermaceti organ lies the "junk" which consists of compartments of spermaceti separated by cartilage. It is analogous to the melon found in other toothed whales. Running through the head are two air passages.

The left passage runs alongside the spermaceti organ and goes directly to the blowhole, whilst the right passage runs underneath the spermaceti organ and passes air through a pair of phonic lips and into the distal sac at the very front of the nose. The distal sac is connected to the blowhole and the terminus of the left passage.

When the whale is submerged, it can close the blowhole, and air that passes through the phonic lips can circulate back to the lungs. The sperm whale, unlike other odontocetes, has only one pair of phonic lips, whereas all other toothed whales have two, [] and it is located at the front of the nose instead of behind the melon.

At the posterior end of this spermaceti complex is the frontal sac, which covers the concave surface of the cranium. The anterior wall is smooth. The knobbly surface reflects sound waves that come through the spermaceti organ from the phonic lips. The grooves between the knobs trap a film of air that is consistent whatever the orientation or depth of the whale, making it an excellent sound mirror. The spermaceti organs may also help adjust the whale's buoyancy.

It is hypothesized that before the whale dives, cold water enters the organ, and it is likely that the blood vessels constrict, reducing blood flow, and, hence, temperature. The wax therefore solidifies and reduces in volume. Herman Melville 's fictional story Moby-Dick suggests that the "case" containing the spermaceti serves as a battering ram for use in fights between males.

The sperm whale's eye does not differ greatly from those of other toothed whales except in size. The cornea is elliptical and the lens is spherical. There are no ciliary muscles. The choroid is very thick and contains a fibrous tapetum lucidum. Like other toothed whales, the sperm whale can retract and protrude its eyes, thanks to a 2-cm-thick retractor muscle attached around the eye at the equator, [] but are unable to roll the eyes in their sockets.

According to Fristrup and Harbison , [] sperm whales eyes afford good vision and sensitivity to light. They conjectured that sperm whales use vision to hunt squid, either by detecting silhouettes from below or by detecting bioluminescence.

If sperm whales detect silhouettes, Fristrup and Harbison suggested that they hunt upside down, allowing them to use the forward parts of the ventral visual fields for binocular vision. For some time researchers have been aware that pods of sperm whales may sleep for short periods, assuming a vertical position with their heads just below or at the surface. A study published in Current Biology recorded evidence that whales may sleep with both sides of the brain.

When echolocating , the sperm whale emits a directionally focused beam of broadband clicks. Clicks are generated by forcing air through a pair of phonic lips also known as "monkey lips" or "museau de singe" at the front end of the nose, just below the blowhole. The sound then travels backwards along the length of the nose through the spermaceti organ. This back and forth reflection which happens on the scale of a few milliseconds creates a multi-pulse click structure.

However, if the whale matures and the size of the spermaceti organ increases, the tone of the whale's click will also change. A continuous fat-filled canal transmits received sounds to the inner ear. The source of the air forced through the phonic lips is the right nasal passage.
