Well one girl here had her first litter at 10"-11" she's now slightly under 15" and 7ish years old. I thought she would max out at 12", even though I knew she was a Venezuelan. Where as another Columbian girl here has maxed out at 12" after many litters. Even if girls start having pups at 8" they won't stay 8". It's rare to see any female under 12" after they are much older, even hystrix or scobina. They generally put on size with every litter. Males on the other hand, once rolled, seem to slow down significantly or just stop in general. The mini marble boys here topped out at 9" and 10".Here's my question - how much larger would you expect a ray to grow AFTER he/she begins reproducing?
Female Marble has pups at say 8" across. IS she having pups at less then half her expected adult size or is it safe to say IF she's having pups at 8" across that she wouldn't be expected to get a whole lot bigger?
I would say those are average sized marbles. I would guess 9" at 7 months old he's no where near done growing lol.Yea I have been interested in this myself. One of my male marbles came from parents where the mom was about 18" and the Dad about 13" so that's borderline "mini" I guess. Find out in a couple of years lol. He's at about 9" now and about 7 months old .
lol yea def not. Just heard some people consider anything below 13" or so as "minis" but I don't know lol splitting hairs I guessI would say those are average sized marbles. I would guess 9" at 7 months old he's no where near done growing lol.
