How big are krill and how many does it take to feed a whale?
Bashfulbob31
The krill I have seen were reddish orange in colour, about 30 mm long, and en route to the Antarctic, the ocean around us was quite coloured. A bucket just lowered over the side produced a layer of krill about 20 mm deep at the bottom.
These shrimp like animals are a very important part of the food chain, living on phyto plankton and other tiny creatures, and in turn providing a food source for whales, seagulls, and penguins.
They are (wastefully) harvested as fertilizer.

Blue whale behavior?
Blue Whales feed almost exclusively on krill, though they also take small numbers of copepods.[24] The species of this zooplankton eaten by Blue Whales varies from ocean to ocean. The whales always feed in the areas with the highest concentration of krill, sometimes eating up to 3,600 kg (8,000 lb) of krill in a single day.[24] This means that they typically feed at depths of more than 100 m (330 ft) during the day, and only surface feed at night. Dive times are typically 10 minutes when feeding, though dives of up to 20 minutes are common. The longest recorded dive is 36 minutes (Sears 1998). The whale feeds by lunging forward at groups of krill, taking the animals and a large quantity of water into its mouth. The water is then squeezed out through the baleen plates by pressure from the ventral pouch and tongue. Once the mouth is clear of water, the remaining krill, unable to pass through the plates, are swallowed. The Blue Whale also incidentally consumes small fish, crustaceans and squid caught up with krill Source: Wikipedia
What is the difference between the blue whale and the killer whale?
There are two distinct groups of whales, toothed and baleen whales. The baleen whale is a baleen whale due to its baleen plates in the mouth instead of teeth. The killer whale has teeth which means it chews its food and eats larger animals. The blue whale eats krill and other little organisms floating in the water. The baleen plates allow the whale to take in water and the krill and pushes the water through the plates which hold back the krill and other larger organisms, it then swallows the food that was left behind. This is the main distinction between the two whales.
How does the mother and father take care of the baby killer whale?
the whales swim by the mama whale and get feed by her and fights for the baby
What are blue whale prey to?
I don't think that they do. If you are referring to within the animal kingdom, they are the largest animal so nothing can usually take them down. But if you mean people, I don't know that any culture normally does.
What are whales preditors?
Adult humpbacks have no natural predators. Man has severely affected humpback whale populations by killing them for years. By the 19th century, many nations (USA in particular), were hunting the animal heavily in the Atlantic Ocean, and to a lesser extent in the Indian and Pacific Oceans. This widespread hunting sharply reduced whale populations.It is estimated that during the 20th century, at least 200,000 humpbacks were taken, reducing the global population by over 90%, with North Atlantic populations estimated to have dropped to as low as 700 individuals. To prevent extinction, the International Whaling Commission banned commercial humpback whaling in 1966. By that time the population had been reduced to around 5,000. That ban is still in forcesharks
What is the largest predator in the world?
The Blue Whale. At up to 33.58 meters (110 ft 2 in) in length and 172 metric tons (190 short tons) or more in weight, it is the largest animal ever known to have existed. What makes the Blue Whale a predator is that, as with other baleen whales, its diet consists almost exclusively of small crustaceans known as krill. The whales always feed on large amounts of krill, sometimes eating up to 3,600 kilograms (7,900 lb) of krill in a single day. Though the whales sometimes take small numbers of copepods, a form of zooplankton, the majority of their diet consists of living organisms, making the Blue Whale the world's largest predator to date. the largest land preditor is the polar bear weighing in at 1,500 lbs that's 3/4 of a ton, only the grizzly can compete with that with a 500 lbs difference
What kills a blue whale and how do they kill it?
They can die because of old age or some other kind of killer mammmal can kill them. Whalers can kill them either on purpose or possibly by accident. They can die because of food shortage. Maybe of some kind of sickness or diesease.
How many harpoon shots can the average whale take?
6.8
Do whale sharks kill?
Not usually but there may have been a few cases, they are known to feed on the whale if it has been killed. They probably would want to kill a Whale (but wouldn't take this risk they can weigh TONNES and tonnes) they probably wouldn't mess with one to be honest.
What can you take for your bones and joints?
Try Krill oil
What is a baleen whale?
Baleen whales are a group of whales that are filter feeders. Instead of teeth they have baleens which are long plates acting as a sieve. They take a big gulp of water and filter out the krill, small fish etc and swallow.
What kind of food baleen whales eat?
Baleen whales use their baleen plates to filter feed. They eat small fish, krill and plankton.
