Longevity and Growth of the Crabs Callinectes sapidus and Callinectes rathbunae (Decapoda: Portunidae) in Paraíso Tabasco Mexico

Acta Zoologica, EarlyView.
ABSTRACT Individual growth models are important in fisheries of natural populations and can be incorporated in production models to estimate their maximum sustainable yield. Blue crab species, Callinectes sapidus and Callinectes rathbunae were obtained in the Mecoacán lagoon, Paraíso, Tabasco Mexico by “nasa” and “yahual” nets. Biometric values such as

Male‐territory‐visiting polygamy in the sand‐dwelling goby Fusigobius inframaculatus (Gobiidae) inhabiting reef caves

Journal of Fish Biology, EarlyView.
Abstract We conducted an observational field survey of the innerspotted sandgoby Fusigobius inframaculatus on reefs of Kuchierabu‐jima Island, southern Japan, to investigate its mating system. Individuals of the goby maintained home ranges on sandy bottoms within rocky caves or beneath overhangs that served as shelters. Of 34 identified individuals, 32%

Post‐hatching development of the remote‐tactile bill‐tip organ in precocial shorebirds (Scolopacidae)

Journal of Anatomy, EarlyView.
Juvenile scolopacid shorebirds possess well‐developed osteological correlates of tactile bill‐tip organs, indicating sensory systems for remote‐touch foraging are present from early life. Ontogenetic changes in bill‐tip morphology suggest ecological specialisation and interspecific variation develop later, after fledging in these highly precocial ...
