Sperm whale (Physeter macrocephalus)
Yes, some hominids had larger cranial capacities than modern humans. Notably, the Neanderthals (Homo neanderthalensis) had an average cranial capacity of about 1,450 cubic centimeters, which is larger than the average for modern humans, around 1,350 cubic centimeters. Additionally, the prehistoric species Homo heidelbergensis and certain specimens of Homo erectus also exhibited larger cranial capacities. However, larger brain size does not necessarily correlate with higher cognitive abilities.
Animals
Probably the Parson's, there big but not very attractive. LOL. look em up
Red kangaroos are the largest of all the kangaroo species, so they are probably also the strongest of the kangaroo species.
Animals
If you mean what species of tree makes the largest specimens, then it is probably the Sequoia Wellingtonia found in California, individual trees can grow to 320 feet with a girth of 90 feet although some specimens are larger.
No, the largest species of bear is the Kodiak bear :D
The largest number of species are the insects as a whole, be they flying or crawling.
Cranial capacity is often used as an indicator of brain size, although it is not a direct measure of intelligence. Larger cranial capacity may suggest a larger brain, which can potentially influence cognitive abilities and complex behaviors in some species.
The group that contains the largest number of species is species.
The largest cactus species found in Arizona is the Saguaro cactus.
Insecta has the most species and probably the greatest biomass as well.
