May 10, 2022
The way I’ve heard it, the Irish Wolfhound has the tallest average height, but the tallest individual was a Great Dane. I had the latter growing up and it’s amazing how such large animals can be around small children and never knock them over or otherwise hurt them by not knowing there own strength (although God help the stranger who goes near ‘their’ kids without permission!).

Equally amazingly, they somehow manage to always find a spot where they take up very little space, despite their huge size. Absolute heartbreakers though, unfortunately they don’t live very long due to the way they’re bred. :-(

Can anyone tell me the difference between colossal squid, giant squid, and architeuthis?
+7
Level 50
Jul 11, 2014
The colossal squid, which still has not been seen alive in its natural habitat, is thought to be even larger than the giant squid (although its tentacles are shorter). The largest known colossal squid was hauled to the surface by fishermen off New Zealand in 2007. It weighed around 1,000 pounds. Unlike the giant squid, whose arms and tentacles only have suckers lined with small teeth, the colossal squid's limbs are also equipped with sharp hooks: some swivelling, others three-pointed. Its body is wider and stouter, and therefore heavier, than that of the giant squid. Colossal squid are believed to have longer mantles than giant squid, although their tentacles are shorter. The squid exhibits abyssal gigantism. The beak of M. hamiltoni is the largest known of any squid, exceeding that of Architeuthis (giant squid) in size and in robustness. So that's the difference between colossal and giant. Architeuthis is easy. It's the giant squid's genus, and is often simply said to mean giant squid.

Fun fact: hybrids of blue whales and fin whales are rare but can actually grow larger than blue whales, and unlike most hybrids they are fully fertile because blue and fin whales have the same diploid number :-)

"can actually grow larger than blue whales".

Source? I'm curious.

+1
Level 71
Aug 30, 2016
The hybrid's size is intriguing, because it seems to have a growing capacity more similar to the Blue whale. Immature hybrid specimens have been found to be larger than fully mature fin or blue whales. I know this was noticed in at least one quite old publication: (Cocks, 1887), but sadly they are very rare in general and still being hunted, so there are too few to do a really comprehensive analysis. But in theory they could be the largest animals of all time :-)

It seems 'imprinted genes' play a role in this, much like why Ligers are larger than Tigers.

A liger is the hybrid offspring of a lion (male) and a tigress. They grow larger than both of their parents (9.8 - 11 ft in length)
+1
Level 31
May 12, 2022
For those wondering, as I understand it female tigers are the only ones which pass on the hormone for growth, so in a pairing with a male lion and female tiger the offspring can grow much larger than either. However with a pairing of a female lion and a male tiger, the offspring can only ever be smaller than the parents.

While I agree that the metric system would make more sense, both due to widespread use and the logic of the system itself, I don't think that knowing the specific weights is necessary to find the answers in this quiz.

What's your source for this? Specifically I'm curious about the Andean Condor versus the Eurasian Black Vulture. I've always heard/read that the Andean Condor is the largest bird of prey, and a brief search of Google listings seems to bolster that view. The List of largest birds article on Wikipedia has a section on birds of prey that appears to give both birds the top status, depending on how they are classified.

Level 72
May 8, 2022
There are only three species of elephant, which take up the top three spots on their list. There are two species of gorilla, which take up the top two spots on their list. Meanwhile, there are eight species of bear, with only the two at the top of their list (the rest beaten out by some of the big cats.) And there are over 500 species of shark, many of which are quite small (some less than a foot long!), so you definitely need to be more specific there.
