In the eastern tropical Pacific (ETP), yellowfin tuna (Thunnus albacares) are frequently found swimming under schools of pantropical spotted (Stenella attenuata) and spinner (S.
The most abundant species (abundance; coefficient of variation) were Atlantic spotted dolphins (14,438; 0.63); bottlenose dolphins (13,085; 0.40); pantropical spotted dolphins, S.
Osmunda es el genero mas diverso de Osmundaceae, ya que incluye alrededor de diez especies (Zhang et al., 2013), presentando una distribucion pantropical y templada (Kramer, 1990).
Los cinco generos de la familia Surianaceae forman dos clados, uno constituido por Recchia y Cadellia (endemico a Australia), y otro por el genero monoespecifico pantropical Suriana L.
Previous studies indicate that fluctuations in abundance of the Pantropical spotted dolphin in the Eastern Tropical Pacific are related to sea surface water temperature and thermocline depth throughout its distribution (Au & Perryman 1985, Reilly 1990, Reilly & Fielder 1994, Fieldler & Reilly 1994, Reilly et al.
