These whales live in highly social groups and communicate with one another using a variety of clicks, and sounds. Since they don’t have teeth like a dolphin would, they use a sucking motion to slurp their food into their beak, like a big spaghetti noodle!

Northern Bottlenose whales are extremely deep divers, with the ability to dive 1500 metres plus below the surface, going under for up to 130 minutes! While diving, they hunt for their prey of choice, squid. However, Northern Bottlenose whales are known to be curious and approach vessels more frequently than other species. There is still a lot of mystery surrounding how these whales live. This algae provides nutrition to the coral polyps, helping them to grow more rapidly.Beaked whales are often cryptic and elusive, making them difficult to study. Many scleractinian corals have photosynthetic symbiotic algae in their tissues, called zooxanthellae. Modern corals―scleractinians―first appeared in the Triassic, and include both solitary and colonial species. Both rugose and tabulate corals went extinct at the end of the Permian. These corals receive their name from the table-like horizontal partitions within their chambers. (Solitary forms are often called 'horn corals.') Tabulate corals were exclusively colonial and produced a variety of shapes, including sheetlike and chainlike forms. Rugose corals were both colonial and solitary. Solitary coral lives independently, as a single isolated polyp. Colonial corals live in colonies of hundreds or even thousands of individuals that are attached to one another.

Each group of coral possesses distinctly shaped 'cups' that hold individual animals, or polyps. They possess stinging tentacles, which they use to feed on small planktonic prey.

Corals are sessile relatives of jellyfish and sea anemones.
