Becoming a mother too early: The first record of the smallest ovigerous female of the deep-sea squat lobster Iridonida iris (A. Milne Edwards, 1880) (Decapoda: Munididae)

We report the smallest ovigerous female of Iridonida iris (A.Milne Edwards, 1880) in the literature, collected in the Great Amazon Reef System (GARS).This finding raises some questions about the presence of deep-sea species associated with the GARS, which may be acting as a breeding and migration environment for both coastal and continental slope species.
