Aquatic and Marine Biology

Unlike mammals and birds, most species of reptiles and fish lay their eggs and leave them to hatch and survive on their own. While there are exceptions, parental care is generally absent in the majority of these species.

An anemone and a clownfish share a symbiotic relationship where both organisms benefit from each other. The clownfish receives protection from predators within the anemone's stinging tentacles, while the anemone gets nutrients from the clownfish's waste and protection from potential predators.

The word "sea" refers to the large body of saltwater where fish live. "See" is a verb meaning to perceive with your eyes, and "seem" means to appear to be.

A food web is a complex network of interconnected food chains that shows how energy flows through an ecosystem.

A terrarium is an enclosure, usually made of glass, used for keeping land-dwelling animals like lizards or plants.

An aquarium is a tank or container filled with water for keeping aquatic animals like fish.

An aquarium is a tank or pool for aquatic life. A terrarium is for land-based plants or animals.

Gonyaulax is a genus of dinoflagellates that causes red tides. It contains red pigments, and when it blooms massively, it can make the sea appear red. Hence it is correctly called a red dinoflagellate.

Humans are classified as mammals because they have mammary glands, hair, and are endothermic vertebrates.

Fish are aquatic vertebrates that breathe through gills, are typically ectothermic, and possess fins for locomotion.

Amphibians are ectothermic vertebrates that typically undergo metamorphosis, starting life in water with gills and transitioning to land with lungs as adults.

Walruses rely on sea ice as a platform for resting between foraging trips to the ocean floor, making the loss of ice a significant threat to their survival.

Camouflage is a common adaptation in fish, allowing them to blend into their environment to avoid predators or ambush prey.

Benthos are organisms that live on or in the bottom of aquatic ecosystems, such as worms, clams, and oysters. Fish are generally classified as nekton because they are free-swimming organisms.
