Marine creatures that often attach themselves to the bottoms of boats include barnacles, mollusks like mussels, and various types of algae. These organisms can cling to surfaces underwater, forming biofouling communities. Barnacles, in particular, are known for their hard shells and can accumulate in large numbers, impacting the boat's performance and increasing maintenance costs. Regular cleaning and anti-fouling coatings are often used to manage these attachments.

Many sea creatures attach themselves to rocks and seashells, including barnacles, mussels, and certain types of sea anemones. Barnacles are crustaceans that use a glue-like substance to adhere to surfaces, while mussels attach themselves using strong threads called byssal fibers. Sea anemones, though not as commonly found on shells, can cling to hard substrates using their pedal disc. These organisms often form clusters, contributing to the biodiversity of marine ecosystems.

Encrusting organisms are marine creatures that attach themselves to hard surfaces, such as rocks, coral reefs, or shipwrecks. They grow by secreting calcium carbonate or another hard substance, forming a crust-like covering over their substrate. Encrusting organisms play a vital role in marine ecosystems by providing habitat for other organisms and contributing to reef formation.
Lobster barnacles have a minimal ecological impact on marine ecosystems as they primarily attach themselves to hard surfaces like rocks and shells. They do not directly harm other marine organisms or disrupt the balance of the ecosystem.
Marine creatures like sharks existed in the Jurassic. Marine reptiles like icthyosaurs, plesiosaurs, and thalattosuchians also existed. Thalattosuchians are fully marine reptiles.
The study of underwater creatures is called marine biology. Marine biology focuses on the biology, ecology, and behavior of organisms that live in saltwater environments, such as oceans, seas, and estuaries. Marine biologists study a wide range of organisms, from microscopic plankton to large marine mammals.

Marine creatures are MADE for salt water ONLY. That's why they are able to be SURROUNDED by water.
Sea creatures with shells have evolved various adaptations to protect themselves from predators in their marine environment. These adaptations include hard shells that provide physical protection, camouflage to blend in with their surroundings, and the ability to retreat into their shells when threatened. Some species also have spines or other deterrents to ward off potential predators. Overall, these adaptations help sea creatures with shells survive and thrive in their underwater habitats.
