Sea monster in the context of "Cetacea"

Ceto (/ˈsiːtoʊ/; Ancient Greek: Κητώ, romanized: Kētṓ, lit. 'sea monster') is a primordial sea goddess in Greek mythology, the daughter of Pontus and his mother, Gaia. As a mythological figure, she is considered to be one of the most ancient deities, and bore a host of monstrous children fathered by Phorcys, another child of Gaia and Pontus. The small Solar System body 65489 Ceto was named after her, and its satellite after Phorcys.

Ceto was also variously called Crataeis (Κράταιις, Krataiis, from κραταιίς "mighty") and Trienus (Τρίενος, Trienos, from τρίενος "within three years"), and was occasionally conflated by scholars with the goddess Hecate (for whom Crataeis and Trienus are also epithets).

In Greek mythology, Andromeda (/ænˈdrɒmɪdə/; Ancient Greek: Ἀνδρομέδα, romanized: Androméda or Ἀνδρομέδη, Andromédē) is the daughter of Cepheus, the king of Aethiopia, and his wife, Cassiopeia. When Cassiopeia boasts that she (or Andromeda) is more beautiful than the Nereids, Poseidon sends the sea monster Cetus to ravage the coast of Aethiopia as divine punishment. Queen Cassiopeia understands that chaining Andromeda to a rock as a human sacrifice is what will appease Poseidon. Perseus finds her as he is coming back from his quest to decapitate Medusa, and brings her back to Greece to marry her and let her reign as his queen. With the head of Medusa, Perseus petrifies Cetus to stop it from terrorizing the coast any longer.

As a subject, Andromeda has been popular in art since classical antiquity; rescued by a Greek hero, Andromeda's narration is considered the forerunner to the "princess and dragon" motif. From the Renaissance, interest revived in the original story, typically as derived from Ovid's Metamorphoses. The story has appeared many times in such diverse media as plays, poetry, novels, operas, classical and popular music, film, and paintings. A significant part of the northern sky contains several constellations named after the story's figures; in particular, the constellation Andromeda is named after her.

Cetaceans (/sɪˈteɪʃə/; from Latin cetus 'whale', from Ancient Greek κῆτος (kêtos) 'huge fish, sea monster') are aquatic mammals belonging to the infraorder Cetacea, in the order Artiodactyla. Cetaceans include whales, dolphins and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. They propel themselves through the water with powerful up-and-down movements of their tail, which ends in a paddle-like fluke, using their flipper-shaped forelimbs to steer.

While the majority of cetaceans live in marine environments, a small number reside solely in brackish or fresh water. Having a cosmopolitan distribution, they can be found in some rivers and all of Earth's oceans, and many species migrate throughout vast ranges with the changing of the seasons.

Charybdis (/kəˈrɪbdɪs/ ; Ancient Greek: Χάρυβδις, romanized: Khárybdis, Attic Greek: [kʰárybdis]; Latin: Charybdis, Classical Latin: [kʰäˈrʏbd̪ɪs̠]) is a sea monster in Greek mythology. Charybdis, along with the sea monster Scylla, appears as a challenge to epic characters such as Odysseus, Jason, and Aeneas. Scholarship locates her in the Strait of Messina.

The idiom "between Scylla and Charybdis" has come to mean being forced to choose between two similarly dangerous situations.

A sea serpent is a type of sea monster described in various mythologies and religious texts, most notably Mesopotamian (Tiamat), Ugaritic (Yam, Tannin), Judaic (Leviathan, Rahab), ancient Greek (Cetus, Echidna, Hydra, Scylla), Vedic (Vritra,Surasa) and Norse (Jörmungandr).

Cetus (/ˈsiːtəs/) is a constellation, sometimes called 'the whale' in English. The Cetus was a sea monster in Greek mythology which both Perseus and Heracles needed to slay. Cetus is in the region of the sky that contains other water-related constellations: Aquarius, Pisces and Eridanus.

Tannin (Hebrew: תַּנִּין tannīn; Syriac: ܬܢܝܢܐ tannīnā plural: tannīnē; Arabic: التنين tinnīn, ultimately from Akkadian 𒆗𒉌𒈾 dannina) or Tunnanu (Ugaritic: 𐎚𐎐𐎐 tnn, likely vocalized tunnanu) was a sea monster in Canaanite and Hebrew mythology used as a symbol of chaos and evil.
