Gills (slits) in reptiles?

[bangity]

Question 298
Reptile: loss of gills during development is false??

It is a chordate, and they do have gill slits during embryonic development.

The question is asking which is not a trait possessed by a reptile. Reptiles do not lose their gills during development. The wording is a bit tricky.

I agree with bangity, they are chordates and lose gills at during embryonic development. Question asked, which is not a trait.. obviously a reptile trait would be to lose gills during embryonic development. I'm confused ~.-

I believe the question was asking do they lose gills during development after being born. Reptiles are born with lungs unlike amphibians, are born with both, and lose them during development into adulthood. Reptiles do not lose their gills because they are born with lungs during birth. Maybe their just not talking about embryonic stage of development😕 bad wording maybe.

Reptiles do not have gill slits (neither do people or any other mammals), but amphibians do.

Quote from my textbook: "Pharyngeal slits connect the pharynx, a muscular tube that links the mouth cavity and the esophagus, with the external environment. In terrestrial vertebrates, the slits do not actually connect to the outside and are better termed pharyngeal pouches. Pharyngeal pouches are present in the embryos of ALL vertebrates. They become slits, open to the outside in animals with gills, but disappear in those lacking gills." (Raven Biology 8th ed. p. 682)

Pharygeal pouches = gill slits in embryo development. Dont base it of off one textbook. I have read at least 5 and they say the same thing. I know ppl who laugh at the idea of gill slits in human.

Raven explaination is very clear. But it should be chordates and not all chordates have vertebrates.

I thought all chordates (which reptiles belongs to) have gill silts?
I know this thread is four years old but I am confused with this question as well.
