a invertebrate is a animal without a backbone
The ability of organisms to function within a specific range of salinities or rainfall amounts is known as their ecological tolerance or physiological tolerance. This adaptability allows species to thrive in particular environments, such as freshwater or saltwater ecosystems, and influences their distribution and survival. Organisms may have specialized adaptations, such as osmoregulation in aquatic species, that enable them to cope with varying salinity levels or water availability. Understanding these tolerances is crucial for predicting how species will respond to environmental changes, such as climate change or habitat alteration.
Crabs have adapted to their hydrosphere environment by developing hard exoskeletons for protection, specialized appendages for swimming and scavenging, and gills for breathing underwater. They are also able to regulate their osmotic balance in varying water salinities.

Compared to the seawater around them, most marine invertebrates have a higher concentration of ions inside their bodies to maintain osmotic balance. This helps them regulate the movement of water to prevent dehydration. Marine invertebrates have evolved various strategies, such as osmoregulation and excretion, to cope with the different osmotic challenges posed by their environment.
Places where waters with different salinities meet, known as estuaries or brackish waters, create dynamic environments where freshwater from rivers mixes with saltwater from oceans. This mixing leads to unique ecosystems that support diverse flora and fauna adapted to varying salinity levels. These areas are often rich in nutrients, making them vital for fish spawning and other marine life. Additionally, they play a crucial role in filtering pollutants and providing coastal protection.
The range for annual mean ocean-surface salinities typically falls between 33 to 37 parts per thousand (ppt). This range can vary based on factors such as location, climate, and ocean currents.
