Jellyfish have a gelatinous, umbrella-shaped bell and trailing tentacles. The bell contains the organism's digestive system and reproductive organs, while the tentacles are equipped with stinging cells called nematocysts, which they use to capture prey.
Jellyfish are found in oceans worldwide, from shallow coastal waters to the deep sea. They can thrive in a wide range of temperatures and salinities.
Most jellyfish are carnivorous and feed on small fish, plankton, and other jellyfish. They use their tentacles to sting and immobilize prey before consuming it.
Seahorses have a distinctive appearance, with a horse-like head, long snout, and a prehensile tail. They have a bony external skeleton, which sets them apart from most other fish species. Their bodies are covered in bony plates instead of scales, and they swim upright, using their dorsal fin to propel themselves.
Seahorses inhabit a variety of coastal habitats, including coral reefs, seagrass beds, mangroves, and estuaries. They are often found clinging to underwater vegetation or other structures with their tails.
Seahorses are carnivorous and primarily feed on tiny crustaceans, such as shrimp and copepods. They use their long snouts to suck in prey with remarkable precision.
Lionfish are characterized by their distinctive appearance, which includes red, white, and black stripes or bands along their bodies, and long, venomous spines extending from their dorsal, pelvic, and anal fins. These venomous spines serve as a defense mechanism against predators.
Originally native to the coral reefs of the Indo-Pacific region, lionfish have been introduced to various marine environments around the world. They can now be found in tropical and subtropical waters throughout the Atlantic Ocean, including the Caribbean Sea and the Gulf of Mexico.
Dolphins are members of the family Delphinidae, which includes several species of dolphins, as well as porpoises and orcas (killer whales). There are about 40 species of dolphins, ranging in size from the relatively small Maui dolphin, which grows to about 4.6 feet (1.4 meters) in length, to the largest species, the orca, which can reach lengths of up to 30 feet (9 meters).
