                            Octopuses are carnivores. They hunt crabs, shrimp, fish, and mollusks. They use their beak-like mouth to pierce and consume prey, often with venom.<\/p>\n\n\n\n

                            Behavior<\/strong><\/h3>\n\n\n\n

                            Highly intelligent and solitary, octopuses use camouflage, jet propulsion, and ink clouds for defense. They can unscrew lids, escape tanks, and remember problem-solving tasks.<\/p>\n\n\n\n

                                Jellyfish feed on plankton, small fish, eggs, and larvae. Their tentacles contain nematocysts that stun or kill prey before drawing it into the mouth.<\/p>\n\n\n\n

                                Behavior<\/strong><\/h3>\n\n\n\n

                                Jellyfish are passive drifters but can move vertically by contracting their bell. Many exhibit bioluminescence. Blooms of jellyfish can occur seasonally, impacting fisheries and swimmers.<\/p>\n\n\n\n

                                  Diet varies by species. Green sea turtles primarily eat seagrass and algae (herbivorous), while others like loggerheads eat crabs, jellyfish, and mollusks (omnivorous or carnivorous).<\/p>\n\n\n\n

                                  Behavior<\/strong><\/h3>\n\n\n\n

                                  Sea turtles undertake long migrations between feeding and nesting grounds. Females return to their birth beaches to lay eggs. They spend most of their lives underwater, surfacing to breathe.<\/p>\n\n\n\n

                                          Behavior<\/strong><\/h3>\n\n\n\n

                                          Starfish move slowly using tube feet and have excellent regenerative abilities. They are solitary and use chemical cues to locate food and avoid predators.<\/p>\n\n\n\n

                                          Eels are long, snake-like fish found in both freshwater and marine habitats. They have a smooth, scaleless appearance and some species undertake remarkable migrations.<\/p>\n\n\n\n

                                            Eels live in rivers, lakes, and oceans. Freshwater eels (like American and European eels) migrate to the sea to spawn, while many marine eels live in reefs or seabeds.<\/p>\n\n\n\n

                                            Eels are mostly nocturnal and secretive, hiding in crevices or burrows during the day. Some species, like the electric eel, generate electric shocks to hunt or defend.<\/p>\n\n\n\n

                                              Stingrays inhabit coastal tropical and subtropical marine waters, including sandy bottoms, coral reefs, and seagrass beds. Some species also live in freshwater rivers and lakes.<\/p>\n\n\n\n
