Physiology, behavior, habitat, and morphology are used to determine the degree of adaptation to life on land
for amphipod species and systemization within the four functional groups of the family talitridae. Talorchestia
longicornis is a semi-terrestrial amphipod found in the supratidal zone of estuaries. The present study investigates
the physiological adaptations of this species to life on land through measurements of osmoregulation
and respiration. Over the salinity range of 1–40‰, T. longicornis regulated its hemolymph hyperosmotically at
low salinities and hypoosmotically at high salinities. The isosmotic point was about 27‰. Analogously, hemolymph
chloride levels were well regulated being hyperionic at low salinities and hypoionic at high salinities.
This species is capable of respiration in both air and water. Slopes (b values) of the relationship between
weight and oxygen uptake rates ranged from 0.316 to 0.590. Oxygen uptake rates were higher in air than
water and at night versus day. Q10 values were slightly below 2.0 for respiration in air for amphipods, irrespective
of weight. These physiological adaptations, along with its behaviors, habitat, and morphology,
place T. longicornis within the Group III sandhoppers of the Talitridae.
Physiology, behavior, habitat and morphology are used to determine the degree of adaptation to life on land for breeding amphipod and systemization of the functional four talitridae family Talorchestia longicornis amphipod half the space found in the supratidal the Delta to monitor education. Currently, the physiology of this species living on the land through the temple. osmoregulation and breathe the salt of 1 - 40 ‰, longicornis in.

Physiology, behavior, habitat and morphology are used to determine the degree of adaptation to life on land
for the species and genera. systemization Within four working groups of families talitridae Talorchestia
longicornis. A semi-terrestrial species found in the area of sugarcane supratidal This study explores
the physiology of the species that have lived on this land through the temple osmoregulation
and breathing in the salty 1-40. ‰ T. longicornis control of blood hyperosmotically The
low salinity and hypoosmotically The high salinity points isosmotic is about 27 ‰ Analogously, blood
levels of chloride, which has been controlled well hyperionic the low salinity and hypoionic the high salinity.
This species has the ability to breathe in the air. water slope value (b) the relationship between the
weight and the rate of oxygen uptake between. 0.316 to 0.590 higher than the rate of absorption of oxygen in the air,
water, and at night compared to Q10. Value is slightly lower than 2.0 for breath in the air for amphipods, regardless
of the weight of these physiological and behavioral adaptations of living and morphology,
T. longicornis place within a group of three sandhoppers Talitridae.
