This "colorful" tide occurs in warm waters when there is an increase of protozoa called dinoflagellates

Red Tide

100

Soon after hatching, loggerhead ones ride currents out to sea to escape predators & grow

turtles

100

In 2022 the deepest fish, a snailfish, was found at over 27,000 feet in the Izu-Ogasawara one of these deep ocean depressions

Trench

100

In 1977 this submersible, which shares its name with a chipmunk, found organisms near Hot Springs over a mile deep

Alvin

100

Found in bodies of water & other moist environments, these single-celled algae have cell walls made of silica

Diatoms

200

Marine biology with a touch of military history: during World War II, Scripps Institution of Oceanography scientists identified a crustacean whose noises were interfering with the detection of these enemy vessels

Submarines

200

Although some species of this in the class Asteroidia have more than 20 arms, 5 is the usual number

Starfish

200

The Venus sea fan, a soft type of this, has numerous polyps that grow together in a fanlike pattern, with each polyp having 8 tentacles

Coral

200

A new theory says that as cetaceans evolved from land animals, the nostril moved to the top of the skull & became this orifice

Blowhole

200

Researchers recognize individual whales & follow their migration based on the pattern on the underside of this, each half of the whale's tail

Fluke

300

Some species of shrimp dig burrows that provide shelter for goby fish which, in turn, act as lookout for the nearly blind shrimp; it's an example of mutualism, which, of the main types of this relationship, is the one where both parties benefit

Symbioses

300

Like jellyfish, sea anemones have stinging cells in these organs to paralyze small animals

Tentacles

300

The heaviest bony fish at a weight of more than 6,050 pounds, it has a celestial name & dines mainly on jellyfish

Sunfish

300

Unlike the stingray, this "devilfish" doesn't have a stinger in its tail

Manta Ray

300

The largest species of this fish is the bluefin, which may reach a length of 14 feet & weigh 1,600 pounds

Tuna

400

This cartilaginous fish with a barbed tail & its mouth on its underside lives on the ocean bottom; its relative, the manta ray, is found in open waters, so I wonder how the classic marine biology text, "Rock Lobster" by the B-52s, can possibly have them swimming together

Stingray

400

A brown alga, this largest seaweed can grow 200 feet long & forms forests off the California coast

(giant) Kelp

400

This member of the weasel family is the only marine mammal that catches fish with its forepaws, not its mouth

Sea Otter

400

Baja's sea lions can dive deep because they have the ability to store substantial amounts of this gas in their blood & muscle

Oxygen

Shagreen, the dried skin of this meat eater, was once used as sandpaper

Shark

500

Not always circular, this type of coral reef encloses a lagoon

Atoll

500

This small five-letter animal seen here is the main food source of the Antarctic blue whale

Krill

500

When buried in the sand, skates & rays rely on these holes near the eyes for breathing oxygen

Spiracles

500

This species of penguin that historically have inhabited the Antarctic Pennisula are rapidly declining due to the loss of sea ice.

Adelie

500

Unlike most sea animals, in the sea horse this pair of sense organs can move independently of one another

Eyes
