Sperm whales have demonstrated the ability to swallow people and they do reside in the Mediterranean Sea.

* Cetaceans include toothed whales ( Suborder Odontoceti ), such as the Sperm Whale, dolphins, and porpoises such as the Dall's porpoise.

Sperm whales have only been heard making clicks, while toothed whales ( Odontoceti ) use echolocation that can generate about 20, 000 watts of sound (+ 73 dBm or + 43 dBw ) and be heard for many miles.

Except for the Sperm Whale, most toothed whales are smaller than the baleen whales.

Sperm whales use low frequencies ( a few to perhaps 50 Hz ), while others employ more narrow-band high-frequency sounds ( porpoises, Cephalorhynchus species like Hector's dolphin ).

* Sperm whales ( Physeter macrocephalus ) have the largest brain mass of any extant animal, averaging 7. 8 kg in mature males.

Sperm whales sometimes steal fish from fishermen's lines, making them the largest of all kleptoparasites .< ref >

Sperm whales have also been observed teaming up to herd prey in a coordinated feeding behavior.

Marine Mammal Research: Sperm whales, fur seals, and other marine mammals can be tracked, and therefore studied, around ocean eddies where nutrients and plankton are abundant.

At the peak of the whaling activity in the Sound the company was taking between 900 to 1100 Sperm and Humpback whales in a year.

Sperm are released through ducts that open on the underside of the animal roughly two-thirds of the way along the body.

In 2005, she directed The Sperm Donor, a pilot for NBC starring Maggie Wheeler and In 2006, Bearse teamed with Rosie O ' Donnell to direct The Big Gay Sketch Show, that debuted on Logo on April 24, 2007.

Sperm provided by a sperm bank will always be produced by a donor attending at the sperm bank's premises in order to ascertain the donor's identity on every occasion.

Sperm survive inside the uterus between 48 to 72 hours on average, with the maximum being 120 hours ( 5 days ).

Sperm that carry a Y chromosome, for example, is supplied with essential molecules that are encoded by genes on the X chromosome.

Early names considered for the band included Sperm Festival and Nazi Occult Bureau, and they had not decided on a name by the time they played their first concert, supporting Johnny Thunders in Paris.

Sperm competition is an evolutionary pressure on males, and has led to the development of adaptations to increase males ' chance of reproductive success.

In 2005, Wheeler starred opposite David DeLuise on the NBC pilot The Sperm Donor.

USDA in conjunction with Lawrence Livermore National Laboratories, ' Beltsfield Sperm Sexing Technology ' relies on the DNA difference between the X-and Y-chromosomes.

An unusual feature in the park during the 19th century was the skeleton of an 18 m long Sperm Whale erected on ironwork.

Sperm banks will usually advise whether sufficient stocks of sperm are available from a particular donor for subsequent pregnancies, and they normally have facilities available so that the woman may purchase and store additional vials from that donor on payment of an appropriate fee.

Examples of such songs included " Sperm Ridden Burden " ( which Lorig said Ford wrote about seeing a child on a bus who was being raised by a single mother ) and " O. J.

In 2005, he starred opposite Maggie Wheeler on the NBC pilot The Sperm Donor.

In 2002, a 30-year-old female Pygmy Sperm Whale was washed up on Thurlestone Beach.

Sperm competition has led to other adaptations such as larger ejaculates, prolonged copulation, deposition of a copulatory plug to prevent the female re-mating, or the application of pheromones that reduce the female's attractiveness.

The Speculum Regale describes other cetaceans, including the Sperm Whale and Narwhal.

Sperm banks may supply other sperm banks or a fertility clinic with donor sperm to be used for achieving pregnancies.

Sperm cells that give rise to female ( XX ) offspring after fertilization differ in that they carry an X-chromosome, while sperm cells that give rise to male ( XY ) offspring carry a Y-chromosome.

Sperm can be aspirated from the testicles or the epididymis, and while there is not enough for successful artificial insemination, there is enough to fertilize an ovum by ICSI.

Sperm competition is often compared to having tickets in a raffle ; a male has a better chance of winning ( i. e. fathering offspring ) the more tickets he has ( i. e. the more sperm he inseminates a female with ).

Sperm entering the caput epididymis are incomplete-they lack the ability to swim forward ( motility ) and to fertilize an egg.

Sperm quantity and quality are the main parameters in semen quality, which is a measure of the ability of semen to accomplish fertilization.
