Accumulation, detoxification, and toxicity of dibutyl phthalate in the swimming crab

Chemosphere, 2022
Dibutyl phthalate (DBP) is one of the most commonly used and toxic phthalate esters and has a variety of harmful effects on aquatic animals. However, there is still a lack of knowledge on the accumulation, detoxification, and toxicity of DBP in aquatic animals.

Reproductive dynamics of a swimming crab (Monomia haanii) in the world’s crab basket

Fisheries Research, 2021
Abstract Red swimming crab Monomia haanii is an important export fishery in southern China. M. haanii is mainly sold as lump crabmeat, generating an annual trade of tens of millions of US dollars over the last decade. For such a commercially important crab species, little attention has been paid to the sustainable use of the stocks and there remains ...

Swimming of the pea crab (Pinnotheres pisum)

Animal Biology, 2014
Aquatic organisms have to deal with different hydrodynamic regimes, depending on their size and speed during locomotion. The pea crab swims by beating the third and fourth pereiopod on opposite sides as pairs. Using particle tracking velocimetry and high-speed video recording, we quantify the kinematics and vortices in the wake of the pea crab.

Motoneuronal commands during swimming behaviour in the shore crab

Brain Research, 1990
Neurograms of proximal leg motor nerves were obtained during swimming in the shore crab. Whereas excitor motoneurones fire in bursts, the common inhibitor motoneurone discharges tonically with simultaneous spikes in all the motor nerves. The average firing frequency of the common inhibitor increases as the period of the swimming cycle decreases ...

Why “swimming crabs” are able to swim – The importance of the axial skeleton: A comparison between the “swimming crab” Liocarcinus depurator and two other brachyuran crabs (Cancer pagurus, Carcinus maenas) using μCT and 3D-reconstruction

Arthropod Structure & Development, 2020
Most brachyuran crabs use their pereiopods as walking legs, but there are also a number of species, in which the last (5th) pair of pereiopods (P5) are specialized to permit a unique mode of swimming. One of these P5-swimming crabs is Liocarcinus depurator, commonly found on European shores.

Polarised light-sensitive interneurones in a swimming crab

Nature, 1976
THIS report shows that there are polarisation-sensitive inter-neurones in the crab visual system, contrary to recent speculations1. It also shows that polarised light information in crabs is elaborately processed.

Characterization of PHB in the gonadal development of the swimming crab Portunus trituberculatus

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2020
Prohibitin (PHB) is an evolutionarily conserved multifunctional protein with ubiquitous expression. In this study, we cloned the PHB gene from the testis of the swimming crab Portunus trituberculatus (PtPHB) and analyzed the deduced amino acid sequence. The expression level of phb mRNA in larvae was analyzed using qRT-PCR.

Behavioural and physiological studies of aggression in swimming crabs

Journal of Experimental Marine Biology and Ecology, 1995
Abstract This article reviews three studies of agonistic interactions in pairs of swimming crabs (Liocarcinus depurator and Necora puber) in which behavioural and physiological approaches were combined. In both species most fights were won by the larger crab.

Swimming in the dromiid crab (Homola barbata)

Animal Behaviour, 1970
Abstract Swimming was observed in specimens of the dromiid crab Homola barbota collected at Naples, and the swimming technique was studied by the analysis of cine film. The first, second and third walking legs beat in the frontal plane of the crab. The duration of the backward propulsive stroke is the same as that of the forward recovery stroke.
