For the biochemical data, two factor nested PERMANOVAs were run with gender (male, female) and tissue (foot, hypobranchial gland, rectal gland, prostate, capsule gland) nested in gender.
No biochemical reactions were observed in homogenates of the hypobranchial and rectal gland from male and female snails (Table 1).
The nMDS analyses of homogenates produced an ordination where tight clustering of hypobranchial and rectal gland samples occurred and both showed clear separation from all the other tissues (Fig.
In addition to the normal renal route for eradicating water from the body, sharks also have a rectal gland, which is attached to the posterior end of the gastrointestinal tract.
Assuming that absorption occurs, the additional extracellular fluid volume would probably be eradicated mainly by elevated rectal gland secretions in marine elasmobranchs and/or via greater urine production in elasmobranchs inhabiting FW (where urea loss through higher urine production is a lesser issue).
dorsalis males sequester break-down products of methyl eugenol in the rectal gland and use these metabolites to synthesize a sex pheromone attractive to females (Nishida et al.

The presence of CAH in the intercellular space of epithelial cells has been demonstrated not only in the alkaline gland in the present study, but also in other tissues such as the gall bladder, duodenum, and sweat gland (Hansson, 1968), as well as in the teleost opercular epithelium (Lacy, 1983b) and the elasmobranch rectal gland (Lacy, 1983a).
