How much does the brain of a blue whale weigh?
9 kg
One of the most striking differences between nervous systems is their size (measured as weight or volume) – the brain of a blue whale weighs up to 9 kg while that of a locust weighs less than a gram (Figure 5).
What species has the largest brain-to-body ratio?
Lest you think this metric falls apart only in the insect world, the noble tree shrew has the highest brain-to-body ratio of any mammal despite its puny size. Ten percent of its body weight is brain matter.
Which whale has the heaviest brain?
The sperm whale
The sperm whale has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms). Larger brains don’t necessarily make a smarter mammal.
Does brain weight correlated with intelligence?
In healthy volunteers, total brain volume weakly correlates with intelligence, with a correlation value between 0.3 and 0.4 out of a possible 1.0. Thus, on average, a bigger brain is associated with somewhat higher intelligence.
How big is the brain of a blue whale?
Highly complex but only relatively small in comparison to their size, the Blue Whale brain weighs in at approximately 5 kilograms. The largest brain in the would belongs to the Sperm Whale which weighs in at over 6 kilograms and is larger due to the more complex social structures.
How big is the peduncle of a blue whale?
Bigger than any dinosaur to have ever lived, the Blue Whale averages 22-30 meters in length with a body weight of 90-120 tonnes! The flukes of a Blue Whale can be up to seven meters wide and the muscle running from the dorsal fin to fluke is known as the peduncle, it is the most powerful muscle in the entire animal kingdom.
Which is the most powerful muscle in a blue whale?
The flukes of a Blue Whale can be up to seven meters wide and the muscle running from the dorsal fin to fluke is known as the peduncle, it is the most powerful muscle in the entire animal kingdom. Nothing in the world compares to the size of a Blue and they easily break records on many different elements of the anatomy of a Blue Whale.
How much weight does a blue whale gain in the summer?
The weight of individual blue whales varies significantly according to fat condition. Antarctic blue whales gain 50% of their lean body weight in the summer feeding season, i.e. a blue whale entering the Antarctic weighing 100 tons would leave weighing 150 tons. Pregnant females probably gain 60–65%.
