Coastal animals are diverse species that inhabit the interface between land and sea, including beaches, rocky shores, and coastal wetlands. Adapted to the dynamic environment, they contend with factors like tides, salinity changes, and wave action. Evolution has equipped them with specialized traits like salt tolerance in mangrove-dwelling creatures or burrowing abilities in beach crustaceans. Their habitats vary from tropical coral reefs to temperate seagrass meadows, each hosting a unique fauna. Coastal regions are biodiversity hotspots, serving as feeding grounds, nurseries, and migratory routes for numerous species, playing crucial roles in marine and terrestrial ecosystems.

Coastal animals display a fascinating array of anatomical features suited to life at the land-sea interface. Many have streamlined bodies for efficient swimming, like dolphins, or flattened shapes for burrowing, like crabs. Some, like sea turtles, have flippers for propulsion, while others, such as seabirds, have wings for flight. Many coastal dwellers have specialized senses; for instance, seals have whiskers sensitive to underwater vibrations. Communication varies: dolphins use complex vocalizations, while crabs may wave pincers for signaling. Adaptations to saline environments are common, with some possessing glands to expel excess salt. These diverse traits enable them to thrive in their ever-changing habitats.

Humans have long been intertwined with coastal animals, relying on them for food, transportation, and inspiration. Coastal communities have historically depended on fishing for sustenance and economic livelihood. Iconic coastal animals like dolphins have permeated pop culture, featuring in films like "Flipper" and "Finding Nemo."

Unfortunately, human activities such as pollution, overfishing, and habitat destruction have threatened many coastal species. Conservation efforts are underway globally, including marine protected areas, sustainable fishing practices, and rehabilitation programs for injured animals. Organizations and documentaries, like "The Blue Planet," raise awareness, fostering a growing public commitment to protecting our coastal wildlife and their habitats.
