Accessory Reproductive Organs Dimension of Two Species of Giant African Land Snails Archachatina marginata and Achatina achatina at Three Liveweight Ranges
Bibliographic record
Abstract
A comparative study of the reproductive tract of two species of Giant African Land Snails, Archachatina marginata and Achatina achatina was carried out. Three groups of snails weighing 80-100,101-150 and 151-250 g were used in a 2x3 factorial design, with 5 replicates, involving a total of 30 snails. Dimensions and weights of retractor penile muscle, vas deferens, penis, vagina, oviduct, spermotheca, common duct, albumen gland and little hermaphrodite duct were taken. Results showed that Archachatina marginata had longer, wider and heavier accessory sex organs compared to Achatina achatina except for vas deferens width, vagina length, vagina width, and vagina weight, which were otherwise. Dimensions and weights of the accessory organs increased consistently with liveweight, except for retractor penile muscle width, which had attained maximum size by a body weight of 101-150 g. It can be concluded that Archachatina marginata had better reproductive tract dimension compared to their counterpart (Achatina achatina). It is however recommended that liveweight group 151-250 g be considered as group of choice when considering anatomical display of reproductive parts for demonstrative purpose and testing of manipulating tools for reproductive strategies in both species.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
