SUMMARY: Diving pods of offshore toothed whales and dolphins (odontoceti) feed on squid above mid-oceanic ridges where they are often exposed to oscillations in ambient water pressure when shallow earthquakes suddenly erupt in the seafloor below them. On rare occasion these changes in pressure are too excessive and/or too rapid to be counterbalanced by the whales' pressure regulating anatomy resulting in barotrauma in the sinuses, air sacs, and middle-ear air cavities of each animal's head. Since intact cranium air spaces play a major role in the function of echo-navigation and echo-location, a pressure related injury in this biosonar system renders the victims unable to use acoustic navigation to determine their position and find food. Nor are they able to dive without suffering intense pain.
The injured pod huddles together for protection against sharks and swims slowly away from the epicenter, but not in a random direction. Since water is 800 times more dense than air, the increased resistance (drag) to swimming against or perpendicular to the surface flow turns the whales headfirst and points them downstream in the path of least drag.
Barotraumatized pods can recover after an unknown period of rest on the surface. Those that do not are eventually: (a) guided to a stranding beach by the surface current, (b) harvested by sharks or killer whales, or (c) die and sink to the bottom.
After about a week on the bottom in water less than 100 meters deep, decomposing gases will form and re-float the carcasses that will then be carried by the surface currents to a beach.
Non-navigating whales, carcasses, flotsam, and sea weeds are all deposited on beaches because the current that carried each grain of sand to build the beach in the first place, is the same energy determining the path of everything floating or swimming blindly on the surface.
Where currents wash shoreward, there are beaches, flotsam, and beached whales; where current does not wash toward the shore, there are no beaches, no flotsam, and no beached whales.
What is the smartest species of whale?
Most animal behaviorists consider the dolphin the most intelligent mammal aside from man, yes.
How whales have evolved over time?
Dolphins didn't always have a straight body, a tail, flippers, and fins. Over 50,000,000 years ago, dolphins were 4 legged creatures that lived on land. Over time, their body shape changed. Their front legs became flippers, their hind legs disappeared, and their nostrils was put on top of their head as blowholes!
What does it mean to dream about whales giving birth?
It probably doesn't mean much. Most of the time people have dreams about something that happened or was mentioned in the past week.
Dreams can provide some beneficial understanding into anxieties and feelings on personal issues.
So what I think is that dreaming about killer whales is just the thought about knowing about it.
What time of year do whales migrate?
Many types of whales migrate, with the timing being different depending on the species of the whale. Some seem to migrate to warmer waters in the winter, while others migrate when they are ready to give birth.
A "Blogger Whale" does not exist as a name for a whale.
What sense would be well developed in an owl?
Owls have a great sense of sight, but their eyes cant 'roll' like ours. This is because their eyes are elongated tubes, not balls. They also have a spectacular sense of hearing, and this is what they rely on to hunt at night. Their ears are slits on the sides of their head. Their disc shaped face funnels sound waves into their ears.
The owl's senses of taste and smell are very poor. These senses are not essential for the owl's survival because they rely on sounds and sight to hunt for food.
What products come from whales?
The sperm whale was hunted almost to extinction for its oil. Whale oil was used to light lamps, and thus there was always a great demand for it -- people needed it the way they need electricity today.
What are the hairs in a whale's mouth?
- A: Killer whales and bottlenose dolphins are mammals and one of the features of a mammal is that they are covered in hairor fur. Well killerwhales and bottlenose dolphins donot have hair covering their body, they may have a couple chin whiskers, but nothing more.
How many babies can a whale have at once?
Gestation in Sperm Whale females lasts about 14 to 16 months. A sigle calf is produced at the end of gestation. Lactation proceeds for 19 to 42 months, but calves may suckle up to 13 years. Calves can suckle from females other than their mothers. Females generally have birth intervals of three to six years between calf birth.
Whales that eat plankton have things called baleen plates. They are fleshy plates covered in hairs. the whale approaches the swimming plankton with an open mouth and then closes its mouth. The whale then pushes the water out with its tongue while the baleen traps the krill. The whale then consumes the krill without having to swallow all of the seawater. Some whales do and some whales don't like the killer whale eats meat and other fish etc but whales for example the blue whale only eat plankton.
What amimal kingdomis the whale in?
All cetaceans, including whales, dolphins and porpoises, are descendants of land-living mammals of the Artiodactyl order (even-toed ungulate animals). Both cetaceans and artiodactyl are now classified under the super-order Cetartiodactyla which includes both whales and hippopotamuses. In fact, whales are the closest living relatives of hippos; they evolved from a common ancestor at around 54 million years ago.[1][2] Whales entered the water roughly 50 million years ago.[3] Cetaceans are divided into two suborders:
Are whales the largest creatures in the waters?
Yes Blue whales are the largest creachers in the waters.
The only species that's reliably white is the beluga whale. Check out the related question for that.
Nature does create paler individuals among the whale species every now and then, but they're all at most "kinda" white.
What contries still hunt whales?
Japan, Norway, and Iceland still conduct whaling. Japan uses a loop hole in the moratorium on whaling. They claim they are conducting research, but that is widely disputed. There are also some Alaskan Natives who engage in whaling.
In what part of the whale the ambergris came from?
Ambergris is only produced by sperm whales. It's a secretion from the intestines, and may be formed to ease the passage of hard objects through the digestive system (giant squid beaks have been found embedded in Ambergris).
Ambergris is usually found on coastal beaches or floating on the sea after being passed as fecal matter or vomited (if a mass is too large to pass through the intestines). It may also be found in the abdomens of dead specimens (as described in Moby Dick).
Historically, Ambergris has been used as a perfume base, but in the 1970s t was banned from use in many countries, including the United States, because of its origin within a vulnerable whale species.
How is dolphin and a whale alike?
Dolphins and fish are alike, but also very different. They are both in the Kingdom Animalia. However, there are several differences. For example, fish can live in frsh or salt water. Dolphins only live in salt water. Also, dolphins are mammals and fish aren't. Fish lay eggs, but with dolphins, the femal gives birth to a new living young dolphin. HOPE THIS HELPS hey people your ugly
A pod is a social group of whales. The bond between mother and calf is the strongest. Members of a pod may protect one another.
Why plastic is more dangerous... than what? Your question isn't complete, however, I can still give you a reason why plastic is more dangerous than metal. (In water bottle form.) Plastic is more dangerous than metal in water bottle form because when plastic heats up (like say it's left in a hot car for a long time) it releases a chemical called Bisphenol A (BPA) into the water or whatever is in your water bottle. This is potentially harmful. Metal does not release this kind of chemical. I hope I helped!! :)
Where you can find the blue whale now?
Blue Whales can be found in almost every sea and ocean in the world. They were the most widely spread whale species until Man started hunting them down. They were once in numbers of around 200,000 or more and now there are only 20,000 or so animals left in the wild.
They can be found in areas that are abundant in "Krill" their favorite prey species.
They don't live in family groups. They are solitary animals. They are known to be along one or two individuals at most and that too only for short periods of time.
What kind of whale is a narwhal?
they are found in cold weather like the arctic. AND NARWHALS ARE TRULY AWESOME!
