Hello, community,
I need everyone's help to know what's the species of the bigger tortoise in this picture. I know the little one is Texas tortoise. But I'm not sure that the bigger one is also that species.

Bigger one looks like a DT, desert tortoise
They should not be together as different species should never be mixed and tortoises never kept in pairs. Hopefully they were put together just for the picture.

Thanks for your response. Do you mean that the bigger one is a Gopherus agassizii?
I keep them separated by species but I have like 5 of each species.

It might be a bolson's tortoise, native to Mexico.

Yvonne you are probably right! Rare tortoise - Gopherus flavomarginatus. They grow huge. But these guys look dry and need more than lettuce in their diet, if that is what they are getting all the time? Maybe it's just for the picture.

Hello! Yeah, it was just for the picture. Diet includes prickly pear and other vegetables, sometimes with vitamins added. They live in grass outside with places to get sunlight or shadow.

I've taken more pictures, because I'm still unsure after checking on Google.IMG_20240510_183818.jpgIMG_20240510_183816.jpgIMG_20240510_183801.jpgIMG_20240510_183807.jpg

Both look like berlandieri to me. A little deceiving with the aberrant 3dr ventral scute, as that is normally the widest ventral in only berlandieri. No picture of the gular as that is also an identifier with polyphemus having a rounded (or even sometimes single) gular and berlandieri - a forked gular. Also both have the classic wedged shape with the rear wider than middle or front.

From what I see 95% sure both berlandieri.

Thanks for your very impressive explanation. I appreciate all the data.

I agree. I was going by size in the first picture, assuming the smaller tortoise was full size, making the other tortoise bigger than a Texas. But after seeing the larger tortoise in relationship with the human hand, I realize it's not as big as I thought
