Descripción: Syngnathidae are a family of fish known for male pregnancy. Males present a brooding organ called brood pouch that can be on the trunk (Nerophinae) or the tail (Syngnathinae) (Yan-Hong et al., 2020). The brood pouch diverges into five types: an open pouch where the eggs are glued to the ventral surface (A) (e.g., Nerophis maculatus [a]); an open pouch with eggs compartments (B) (e.g., Phyllopteryx taeniolatus [b]); a partially closed pouch with egg compartments and lateral protective skinfolds (C) (e.g., Corythoichthys haematopterus [c]); a closed pouch with eggs compartments and skinfolds that merge at the center and can be inverted (D1), overlapping (D2) or everted (D3) (e.g., Syngnathus typhle [d]); and a sealed pouch with a sac-like structure (E) (e.g., Hippocampus abdominalis [e]) (Akari et al., 2022) (Wilson et al., 2001) (Herald, 1959).

Los Syngnathidae son una familia de peces conocida por la preñez de los machos. Los machos presentan un órgano de cría llamado bolsa de cría que puede estar en el tronco (Nerophinae) o en la cola (Syngnathinae) (Yan-Hong et al., 2020). La bolsa de cría se divide en cinco tipos: una bolsa abierta en la que los huevos están pegados a la superficie ventral (A) (e.g., Nerophis maculatus [a]); una bolsa abierta con compartimentos para los huevos (B) (e.g., Phyllopteryx taeniolatus [b]); una bolsa parcialmente cerrada con compartimentos para los huevos y pliegues cutáneos protectores laterales (C) (e.g., Corythoichthys haematopterus [c]); una bolsa cerrada con compartimentos para los huevos y pliegues cutáneos que se fusionan en el centro y pueden estar invertidos (D1), superpuestos (D2) o evertidos (D3) (e.g., Syngnathus typhle [d]); y una bolsa sellada con una estructura similar a un saco (E) (e.g., Hippocampus abdominalis [e]) (Akari et al., 2022) (Wilson et al., 2001) (Herald, 1959).
