Fundorte:
The small and common gastrotrich Chaetonotus (Ch.) multispinosus is characterized by its short-spined, roundish scales, which are cut out at the posterior end:
Ch multispinosus: ventral
The short spines that give the species its name can be seen in cross-section. The short, club-shaped pharynx is very typical:
Ch multispinosus: cross section
The ventral intermediate field is covered with a few rows of roundish, keeled scales. The posterior end is formed by two larger, short spiny plates, which are bordered by two pairs of small, also short spiny keel scales:
