Através a radiação adaptativa, eles desenvolveram uma enorme variação de formas e estruturas. How does this differ from cartilaginous fish (class Chondrichthyes)? The key difference between Sarcopterygii and Actinopterygii is that sarcopterygii is a class of bony fish, consisting of lobed fish that have fleshy, lobed and paired fins.Meanwhile, actinopterygii is a class of bony fish, consisting of ray-finned fish that have fins supported by horny spines. These scales are smooth and overlapping. Osteichthyes is the largest class of vertebrates, with over 28,000 species, but you may be . Osteichthyes is a taxonomic group of fishes that includes the ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii. Jerkov 17:50, 11 June 2006 (UTC) I think Osteichthyes should be a superclass and it's right that Sarcopterygii and Actinopterygii are listed as classes. Bony fish are further divided into two extant clades: Actinopterygii (ray-finned fish) and Sarcopterygii (lobe-finned fish). Cartilaginous fish are true fish. It diverged from Chondrichthyes 420 million years ago. Lebih kurang 20 ribu spesies ikan bertulang sejati . Bony fish have no placoid scales. There are only eight living species of sarcopterygii. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines ("rays"), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). The skeleton is more or less bony, notochord may persist in part and the tail is usually homocercal. A lungs. Kurang lebih 29000 jenis 95% dari seluruh jenis ikan, 50% dari seluruh vertebrata. The oldest Sarcopterygians were found in the Uppermost Silurian.

Fosil Ostichthyes pertama diketahui muncul pada periode Silurian dan mengalami perkembangan di periode Devonian Bawah dan Tengah, telah mempunyai ukuran, bentuk, warna dan mekanisme penyesuaian terhadap lingkungannya. Compare fins in subclass Actinopterygii to Sarcopterygii. The cartilaginous fish, or Chondricthyes, include the sharks, rays, skates, and chimaeras. Many bony fish also have a swim bladder, a gas-filled organ that helps to control the buoyancy of the fish. Osteichthyes, or bony fishes, includes two major groups: Sarcopterygii, or lobe-finned fishes, and Actinopterygii, or ray-finned fishes. Figure 11.10.
