The size of solid bodies does not include an object's atmosphere. For example, Titan looks bigger than Ganymede, but its solid body is smaller. For the giant planets, the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure. [11]
As for length, the longest extant bony fish on earth is the giant oarfish (Regalecus glesne). Slender and compressed, it averages over 6 m (20 ft) long at maturity. A specimen caught in 1885 of 7.6 m (25 ft) in length weighed 275 kg (606 lb). The longest known example, which was hit by a steamship, was measured as 13.7 m (45 ft) long. [1]
Initially, the names given to minor planets followed the same pattern as the other planets: names from Greek or Roman myths, with a preference for female names. With the discovery in 1898 of the first body found to cross the orbit of Mars, a different choice was deemed appropriate, and 433 Eros was chosen.
[13]: 206 Thelodonts were morphologically very similar, and probably closely related, to fish of the classes Heterostraci and Anaspida, differing mainly in their covering of distinctive, small, spiny scales. These scales were easily dispersed after death; their small size and resilience makes them the most common vertebrate fossil of their time.
The world's smallest fish depends on the measurement used. [1]Based on minimum standard length at maturity the main contenders are Paedocypris progenetica where females can reach it at 7.9 mm (0.31 in), [2] [3] [4] the stout infantfish (Schindleria brevipinguis) where females reach it at 7 mm (0.28 in) and males at 6.5 mm (0.26 in), [1] and Photocorynus spiniceps where males can reach it at 6. ...
Largest specimen of Leedsichthys compared to other Pachycormid fish Leedsichthys is the largest known member of the Osteichthyes or bony fishes. [ 20 ] The largest extant non-tetrapodomorph bony fish is the ocean sunfish , Mola mola , being with a weight of up to two tonnes an order of magnitude smaller than Leedsichthys .
The planets as known during classical antiquity: the Moon, the Sun, Mercury, Venus, Mars, Jupiter, and Saturn. Earth analog: A planet or even a superhabitable planet with conditions to be compared with those found on Earth. Hypothetical planet: A planet or similar body whose existence is not proven, but is believed by some to exist.
More than 5,600 fish species inhabit Neotropical freshwaters alone, such that Neotropical fishes represent about 10% of all vertebrate species on the Earth. Exceptionally rich sites in the Amazon basin , such as Cantão State Park , can contain more freshwater fish species than occur in all of Europe.
