In Psalm 104 the Leviathan is describes as an intelligent mammal that gather around Phoenician ships, the most obvious Animal would be a Dolphin, but I am learning towards the Mediterranean monk seal (Monachus monachus). One word for which is ἁλοσύδνη (halosydne)
Psalm 104:25
𐤆𐤄 𐤄𐤉𐤌 𐤂𐤃𐤅𐤋 𐤅𐤓𐤇𐤁.𐤉𐤃𐤉𐤌
ἅδε ἁ κυανὰ μεγάλα και εὐρυόδεια
"This great blue-sea and wide-pathed-earth"
Psalm 104:26
𐤔𐤌 𐤀𐤍𐤉𐤅𐤕 𐤉𐤄𐤋𐤊𐤅𐤍 𐤋𐤅𐤉𐤕𐤍 𐤆𐤄 𐤉𐤑𐤓𐤕 𐤋𐤔𐤇𐤒 𐤁𐤅
ἔνθα ναῦς ἔρχοντα ἥδε ἁλοσύδνη κεραμεύῃ ἀγωνίζεσθαι αὐτῷ
"There the ships set out. This seal, you made to play with him."
Psalm 104:27
𐤊𐤋𐤌 𐤀𐤋𐤉𐤊 𐤉𐤔𐤁𐤓𐤅𐤍 𐤋𐤕𐤕 𐤀𐤊𐤋𐤌 𐤁𐤏𐤕𐤅
Πάντα σε ἐλπίζουσιν διδόναι φάγημα τηνικάδε
"They all hope that you give them food right now"
Psalm 104:28
𐤕𐤕𐤍 𐤋𐤄𐤌 𐤉𐤋𐤒𐤅𐤍 𐤕𐤐𐤕𐤇 𐤉𐤃𐤊
δίδου αυτοις λέγουσιν πέτεαι γυῖον σου πιμπλᾶσιν ἀγαθοῦ
"As you give to them, they rush around, as you open your hand, they are filled with good"
