You should know, Chondrichthyes and Osteichthyes are not valid taxa anymore, they are both paraphyletic to tetrapods (clade Tetrapoda), Chondrichthyes is now replaced with Holocephali and Elasmobranchii both now evaluated into full classes and Osteichthyes is now replaced with Actinopterygii and Sarcopterygii both now evaluated into full classes, both lobe-finned fish (class Sarcopterygii) and tetrapods (clade Tetrapoda) are grouped together under the clade Neoteleostomi, whereas ray-finned fish (class Actinopterygii) are basal to both, both Actinopterygii and Neoteleostomi constitute the clade Euteleostomi (Bony Vertebrates), elasmobranchs (class Elasmobranchii) are now thought to be more closely related to bony vertebrates (clade Euteleostomi) than to holocephalans (class Holocephali), thus placing them elasmobranchs and bony vertebrates together under the clade Teleostomi, while holocephalans are considered the most basal of all the extant jawed vertebrates.

[@nefelpitou]

I've never heard of chondrichthyes being paraphyletic before, as far as I knew it's generally an accepted taxon? Obviously not im disagreeing that osteichythes is paraphyletic with regards to Tetrapoda, thats well known, but I've never seen a study that claims elasmobranchs are more closely related to bony fish than to holocephali

[@fubberpish3614]

The number of recognised families likely depends on which source you are using for taxonomy. The ranking of clades is inherently pretty arbitrary, so different sources will likely classify things differently resulting in different numbers of recognised families - for example, one source could consider a group to contain 4 distinct families, whereas another considers it to be only a single family with four subfamilies.

Isn't it time we start thinking about lumping birds over with the reptiles?

[@indyreno2933]

Actually, parrots (order Psittaciformes) are now officially split into eight extant families under three different superfamilies, with the three superfamilies of parrots being Strigopoidea (New Zealand Parrots), Cacatuoidea (Cockatoos), and Psittacoidea (True Parrots), the new zealand parrots (superfamily Strigopoidea) are the most basal of the three parrot superfamilies and are split into two extant families: Nestoridae (Kaka and Kea) and Strigopidae (Kakapo and Fossil Relatives), the cockatoos (superfamily Cacatuoidea) are split into two extant families: Nymphicidae (Cockatiel and Fossil Relatives) and Cacatuidae (True Cockatoos), and the true parrots (superfamily Psittacoidea) are the largest parrot superfamily and are split into four extant families, with the most basal of the four extant families to be Pezoporidae, which contains all true parrot populations native to Oceania, then followed by Psittaculidae, which is native only to Asia, leaving the most recent split to be between Psittacidae that includes all parrot populations native to Africa and Aridae which is where all parrots native to the New World belong to.

[@fubberpish3614]

Which taxonomy splits the parrots into 8 families? I use eBird's Birds of the World for family-level taxonomy, and they recognise only four families - Strigopidae, Cacatuidae, Psittacidae and Psittaculidae

[@indyreno2933]

@fubberpish3614, there are actually eight: Nestoridae (Kakas and Kea), Strigopidae (Kakapo and Fossil Relatives), Nymphicidae (Cockatiel and Fossil Relatives), Cacatuidae (True Cockatoos), Pezoporidae (Oceanian True Parrots), Psittaculidae (Asiatic Parrots), Psittacidae (African Parrots), and Aridae (New World Parrots), they are also split officially into three superfamilies: Strigopoidea (New Zealand Parrots (contains Nestoridae and Strigopidae)), Cacatuoidea (Cockatoos (contains Nymphicidae and Cacatuidae)), and Psittacoidea (True Parrots (contains Pezoporidae, Psittaculidae, Psittacidae, and Aridae)), based on here, Strigopidae includes only the kakapo (Strigops habrotilus), while all other living new zealand parrot species being the Kea (Nesopsittacus notabilis), South Island Kaka (Nestor meridionalis), and North Island Kaka (Nestor septentrionalis) belong to the family Nestoridae, not all cockatoos belong to the family Cacatuidae, the cockatiel, which is the smallest living cockatoo species is placed in its own family, which is Nymphicidae, whereas Cacatuidae is restricted only to the larger cockatoo species, Psittaculidae is rendered as paraphyletic and Psittacidae is rendered as polyphyletic, all african parrot populations belong to the family Psittacidae, which therefore redefines Psittacidae as an exclusively African family, which does evaluate new world parrots into a full family that is still the sister group to Psittacidae, all populations of true parrots native to Oceania are now thought to be grouped together under one family called Pezoporidae, which is shown to be the most basal of the four extant families of true parrots, this helps broaden the exclusively oceanian origin of parrots (order Psittaciformes), so for this reason, there are eight extant families of parrots and parrots are also split into three superfamilies, which does mean that true parrots (superfamily Psittacoidea) are split into four extant families with the family Pezoporidae that includes all true parrot populations native to Oceania being the most basal, then followed by the asiatic parrots of the family Psittaculidae, leaving the most recent split to be between the african parrots of the family Psittacidae and the new world parrots of the family Aridae, both new zealand parrots (superfamily Strigopoidea) and cockatoos (superfamily Cacatuoidea) are split into two extant families with the two extant families of new zealand parrots being Nestoridae (Kakas and Kea) and Strigopidae (Kakapo and Fossil Relatives) and the two extant families of cockatoos being Nymphicidae (Cockatiel and Fossil Relatives) and Cacatuidae (True Cockatoos).

[@fubberpish3614]

@no2933 that I understand, I am not saying you are wrong. There are papers supporting this 8-family arrangement. But what I'm asking is which, if any, bird taxonomy source has accepted this change? Every single source I can find (Birds of the World, IOC, etc) follows the 4-family classification of parrots. Also, as for the position of the Cockatiel, I was under the impression it was more closely related to the "white cockatoos" (Cacatua, Eolophus, Lophochroa) than to the "black cockatoos" (Zanda, Calyptorhynchus and Probosciger), making a Cacatuidae excluding Nymphicus paraphyletic. Not sure where Callocephalon falls into this however. Although, I could be wrong.

[@indyreno2933]

@fubberpish3614, cockatoos are defined by the superfamily Cacatuoidea, which is actually now split into two extant families: Nymphicidae (Cockatiel and Fossil Relatives) and Cacatuidae (True Cockatoos), the latter contains all of the larger cockatoo species, while the cockatiel, which is the smallest living cockatoo species is different enough to have a family of its own, also, the subfamilies that true cockatoos (family Cacatuidae) are now split into are Callocephalontinae (includes Callocephalon), Eolophinae (includes Eolophus and Licmetis), Proboscigrinae (includes Calyptorhynchus, Zanda, and Probosciger), and Cacatuinae (includes Cacatua, Flavolophus, and Lophochroa), thus still making Cacatuidae excluding Nymphicus monophyletic, which officially makes Strigopidae and Nymphicidae the only two extant parrot families to have a single surviving species, with the Kakapo (Strigops habrotilus) being the only surviving member of the family Strigopidae and the Cockatiel (Nymphicus hollandicus) being the only surviving member of the family Nymphicidae, meaning all new zealand parrots belong to the superfamily Strigopoidea but not the family Strigopidae and all cockatoos belong to the superfamily Cacatuoidea but not the family Cacatuidae, which is the reason why both new zealand parrots (superfamily Strigopoidea) and cockatoos (superfamily Cacatuoidea) are split into two extant families, for the new zealand parrots (superfamily Strigopoidea), the two extant families are Nestoridae (Kakas and Kea) and Strigopidae (Kakapo and Fossil Relatives), whereas for the cockatoos (superfamily Cacatuoidea), the two extant families are Nymphicidae (Cockatiel and Fossil Relatives) and Cacatuidae (True Cockatoos), also, there are actually four families of true parrots (superfamily Psittacoidea) not two, which is the reason why it is now said that there are eight extant families of parrots (order Psittaciformes), with the four extant families of true parrots (superfamily Psittacoidea) being Pezoporidae (Oceanian True Parrots), Psittaculidae (Asiatic Parrots), Psittacidae (African Parrots), and Aridae (New World Parrots), because parrots (order Psittaciformes) as a whole are officially accepted to have originated exclusively from Oceania, explaining why new zealand parrots (superfamily Strigopoidea) are the most basal of the three parrot superfamilies and cockatoos (superfamily Cacatuoidea) are primarily native to Oceania, the family Pezoporidae, which is a family of true parrots that contains all exclusively Oceanian populations is treated as the most basal of the four extant families of true parrots (superfamily Psittacoidea), with Psittaculidae, which is redefined as an exclusively Asian family being the second most basal, while Psittacidae is now redefined as an exclusively African family and contains all african populations of the superfamily, while new world parrots have been evaluated into the family Aridae, which is in fact the sister group to Psittacidae, which officially makes african parrots (family Psittacidae) and new world parrots (family Aridae) two the most derived families of true parrots (superfamily Psittacoidea), based on here Psittaculidae no longer includes african parrots other than grey parrots (genus Psittacus) and silver-headed parrots (genus Poicephalus) or true parrots native to Oceania, which is why Psittacidae is redefined to include only all parrot populations native to Africa and all true parrot populations native to Oceania are now lumped together into the family Pezoporidae, thus officially rendering Psittaculidae paraphyletic to new world parrots (family Aridae), with all of its african members now moved back to Psittacidae, which is the sister group to Aridae, while Pezoporidae is the most basal and distantly related from all the four extant families of true parrots (superfamily Psittacoidea) whereas Psittaculidae (now found only in Asia) is the sister group to the Psittacidae + Aridae split.

Fish are not a valid class.

[@indyreno2933]

Correct, they are six different classes: Myxini (Hagfish and Fossil Relatives), Petromyzontida (Lampreys and Fossil Relatives), Holocephali (Chimaeras and Fossil Relatives), Elasmobranchii (Sharks and Batoids), Actinopterygii (Ray-Finned Fish), and Sarcopterygii (Lobe-Finned Fish).

[@ultimulcretin5795]

I'm actually one of those weirdos that would consider 9 classes of fish. If we want to consider fish, as a valid clade or a natural group we would have to include all of the living descendants of that group (following the definition of a monophyletic group). 1. Myxini (the hagfish) 2. Petromyzontida (lampreys) 3. Chondrichthyes (all cartilaginous fishes) 4. Actinopterygii (ray-finned fishes) 5. Actinistia (coelacanths) 6. Dipnoi (lungfishes) 7. Amphibia (frogs, salamanders and caecilians) 8. Reptilia / Sauropsida (including birds) 9. Mammalia (including humans) Following this perspective, we would virtually synonymize the term "Fish" with "Vertebrate", which would render the term useless. So personally, I always like to say, that fish (in the traditional sense) simply don't exist in modern scientific classification.

[@indyreno2933]

@ultimulcretin5795, Chondrichthyes is not valid anymore, it is paraphyletic to the bony vertebrates (clade Euteleostomi), based on here, sharks and batoids, which are collectively known as elasmobranchs are more closely related to bony vertebrates than they are to chimaeras and their fossil relatives, which are known as holocephalans, for this reason, Holocephali and Elasmobranchii are now evaluated into full classes, just like Actinopterygii and Sarcopterygii are evaluated into full classes because Osteichthyes is invalidly paraphyletic, the clade that elasmobranchs and bony vertebrates constitute is called Teleostomi, the clade that lobe-finned fish (class Sarcopterygii) and tetrapods (clade Tetrapoda) constitute is called Neoteleostomi, also, there are actually now ten extant classes of vertebrates: Myxini (Hagfish and Fossil Relatives), Petromyzontida (Lampreys and Fossil Relatives), Holocephali (Chimaeras and Fossil Relatives), Elasmobranchii (Sharks and Batoids), Actinopterygii (Ray-Finned Fish), Sarcopterygii (Lobe-Finned Fish), Amphibia (Amphibians), Reptilia (Reptiles), Aves (Birds), and Mammalia (Mammals).

[@ultimulcretin5795]

@@indyreno2933 Chondrichthyes is no longer valid? Wow, I didn't know that, thank you for sharing, I will definitely have to look more in to this. Also, I'm pretty sure Sarcopterygii shouldn't be considered a class, it includes lungfish and coelacanths, lungfish being more closely related to tetrapods than they are to coelacanths, indicating that Tetrapoda is a subgroup within Sarcopterygii as well.

[@indyreno2933]
