Sling, juvenile, subadult, adult

    Could anybody please explain to me what defines the classifications of sling, juvenile, subadult and adult? is it size? age? What's the cutoff between sling and juvenile, or are they interchangeable terms? Any help would be much appreciated. I'm a little confused.

    They are loose/subjective terms. IMO a sling is a specimen that is between eggsac and Juvenile. A juvenile is when a T gets the coloring of its particular species. A subadult is not yet an adult and an adult is.

    Yep those are all subjective and not scientific. The scientific terms do not corralate to the subjective terms.

    Scientific is egg, pre-embryo, nymph, pre-ultimate, ultimate, and post ultimate. I think :confused:.

    i call all of my T's/slings that are the size of house spiders "slings", well i have 2 that are about 1 1/2" and they look like my bigger curly so i guess i could call them juvies, but i only have one adult (mature).

    I classify mine by size. unless it is mature then i classify mine as juv. or sub-adult.

    Actually, "scientific" would be: egg, postembryo, 1st instar, 2nd instar, 3rd instar, 4th instar, 5th instar... 10th instar... etc., penultimate, ultimate and postultimate.

    The term "nymph" is used more in Europe, especially England, where some call postembryo "nymph-1" and 1st instar "nymph-2".

    As others have mentioned, the terms spiderling, juvenile, subadult and adult are subjective hobby terms. My personal usage is spiderling for early instars without adult coloration, juveniles for later instars that have obvious adult coloration, subadult for larger spiders that are smaller than the species average adult size - if male, they may be penultimate - and adult for ultimate spiders [sexually mature].

    Cheers, Michael
