The deep Atlantic contains some of the world's oldest and most spectacular cold-water coral reefs and deep-sea sponge grounds, which depend on ocean currents to deliver food and disperse offspring.

Cryptozoology has been widely critiqued by scientists.

Cryptozoologists focus their research on entities mentioned in folklore records and rumors.

The Pacific 'Blob' marine heatwave coincided with unexpected die-offs of California sea lions, Guadalupe fur seals, common murres, and Cassin's auklets.

The Baltic Sea anomaly was discovered while the OceanX team was treasure hunting on the floor of the northern Baltic Sea.

Biologists identify new species by following established scientific methodology, in contrast to cryptozoologists.

The immortal jellyfish, Turritopsis dohrnii, can revert from adulthood back to its polyp stage when threatened by danger or starvation.

Cryptozoology claims that cryptids may exist somewhere in the wild despite lack of scientific substantiation.

Scientists have criticized cryptid plausibility due to lack of physical evidence, likely misidentifications, and misinterpretation of folklore stories.

Cryptozoologists are criticized for not following the scientific method when investigating alleged cryptids.

Regional sea-level anomalies can indicate unusual water temperatures, salinities, average monthly winds, atmospheric pressures, and/or coastal currents.

Cryptozoology is classified as a pseudoscience by mainstream science.

Certain marine clams can live for more than 500 years.

Octopuses have three hearts and blue blood; two hearts pump blood to the gills while the third pumps it to the rest of the body.

Researchers used fossil foraminifera species in sediment cores as indicators of past ocean temperatures, since some species prefer warm water while others favor cooler conditions.

Cryptozoology is criticized for relying on anecdotal information rather than scientific evidence.

A Penn State study published in Science Advances on June 30 found that ocean processes and atmospheric processes contribute equally to maintaining the North Atlantic cold blob.

Ancient Aliens Season 2, Episode 3, titled 'Underwater Worlds,' features the lost city of Atlantis, ruins beneath Lake Titicaca, and sunken cities where aliens and humans allegedly mixed.

Researchers at the University of California, Riverside analyzed 20 years of AMOC observations and used 100 years of temperature and salinity data to reconstruct earlier ocean dynamics.

Tabloid newspapers published speculation that the Baltic Sea anomaly was a sunken UFO.

Wombat feces are cube-shaped, with researchers confirming this results from the unique elasticity of their intestines, not diet—helping mark territory without rolling away.

Paleontology examines burrows and cast-off parts of organisms (such as molted shells) as forms of fossil evidence.

The prevailing scientific hypothesis holds that the transition from non-living to living entities on Earth was a gradual process rather than a single event.

Scientists attribute cryptid sightings partly to misidentifications of known animals.

Ovis longipes palaeoaegyptiacus had unique, loosely spiraling horns that came out of the sides of the skull.

The toxic algal bloom during the Pacific 'Blob' period delayed and partially closed recreational and commercial fishing seasons for sardines, anchovies, crabs, and razor clams.

Quantum mechanics concepts and methods have been applied to quantum biology.

Within 1,000 years of humans migrating into the Americas, more than 114 species of large plant-eaters, including woolly mammoths, giant camels, and ground sloths, went extinct.

Conservation paleobiology addresses challenges in modern conservation biology, such as understanding the extinction risk of endangered species.

The Greenland shark has the longest known lifespan of any vertebrate, living up to 400 years, with sexual maturity not reached until around 150 years of age.
