This is a very definite and remarkable agreement, since such a reticular gonocoel is not found in Crustacea (except in the male Apus).
The male possesses elaborate copulatory structures of a chitinous nature, and the eggs are fertilized in the female without even quitting the place where they are formed on the wall of the reticular gonocoel.
The gonadial tubes (gonocoels or gonadial coelom) are originally reticular and paired, though they may be reduced to a simpler condition.

Between the blind gut and the cuticle is a reticular branched tissue which forms the chief substance of the body.
Characteristic forms may be assumed by the young zoogloea of different species, - spherical, ovoid, reticular, filamentous, fruiticose, lamellar, &c., - but these vary considerably as the mass increases or comes in contact with others.
