Legends of the Deep: Mythical Sea Creatures and the Real-Life Animals That Inspired Them
Throughout history, the ocean has been a place of mystery and wonder, fueling legends of monsters, mermaids, and mythical sea creatures. From ancient seafarers to modern storytellers, tales of giant serpents, shape-shifting spirits, and terrifying beasts have captured human imagination. But what if these legendary creatures weren’t just fantasy? What if they were inspired by real-life marine animals?
Bohol, with its rich marine biodiversity, is home to fascinating species that may have influenced myths passed down through generations. As divers, we get a firsthand look at the creatures that might have been mistaken for monsters of the deep. Let’s dive into some of the most famous mythical sea creatures and the real animals that could have inspired them.
The Bakunawa – The Serpent Dragon of the Sea
The Legend
In Filipino mythology, the Bakunawa is a giant sea serpent or dragon believed to cause eclipses by swallowing the moon. This fearsome creature was said to have a massive, gaping mouth, a long eel-like body, and the ability to control the ocean’s tides.
The Real-Life Inspiration
- Oarfish (Regalecus glesne) – This deep-sea fish, often reaching lengths of 10 meters or more, has a long, undulating body that could easily be mistaken for a sea serpent. Rarely seen near the surface, oarfish are known to rise from the depths when sick or dying, possibly fueling ancient stories of giant sea monsters suddenly appearing near shore.
- Sea Snakes – With their elongated, sinuous bodies, venomous sea snakes may have also contributed to serpent myths. Found in Bohol’s waters, these snakes can appear dragon-like when seen gliding effortlessly through the ocean.
Where to See It in Bohol:
- Oarfish are elusive but have occasionally been spotted in deeper waters off Pamilacan Island.
- Various species of sea snakes can be found in Balicasag’s reefs and the sandy bottoms of Panglao’s dive sites.
The Sirens and Mermaids – Enchantresses of the Sea
The Legend
From Greek mythology to European folklore, mermaids and sirens have been depicted as half-human, half-fish beings that lured sailors to their doom. In the Philippines, the Sirena is a water spirit associated with beauty and mystery, sometimes said to live in coral caves.
The Real-Life Inspiration
- Dugong (Dugong dugon) – Often mistaken for mermaids by early sailors, dugongs are gentle marine mammals closely related to manatees. They have human-like facial features, large, expressive eyes, and a slow, graceful way of swimming, which could have fueled mermaid myths.
- Free Divers and PADI Mermaids – Today, modern mermaiding is a real activity! The PADI Mermaid™ program, offered by Sierra Madre Divers, allows divers to experience the beauty of underwater movement in a way that mirrors the legends of sirens and mermaids.
Where to See It in Bohol:
- Dugongs are rare but have been spotted in seagrass meadows around Anda.

The Kraken – The Giant Sea Monster
The Legend
One of the most famous sea monsters in history, the Kraken was described as a massive, tentacled beast capable of dragging entire ships beneath the waves. Norse sailors feared encountering this legendary creature, believing it could create deadly whirlpools in its wake.
The Real-Life Inspiration
- Giant Squid (Architeuthis dux) – Reaching up to 14 meters in length, the giant squid is a deep-sea predator that has been known to rise to the surface and even attack boats. Their long tentacles, large eyes, and powerful beak make them a terrifying sight in the rare moments they are encountered alive.
- Octopuses – With their shapeshifting abilities, ink defense, and problem-solving intelligence, octopuses are fascinating animals that could have inspired many mysterious sea creature stories.
Where to See It in Bohol:
- While giant squid live in the deep sea, divers can spot reef octopuses hiding in coral crevices at Doljo Point and Balicasag Island.
The Nuckelavee – The Horse Demon of the Sea
The Legend
A terrifying figure from Scottish mythology, the Nuckelavee is a half-horse, half-man monster that rises from the sea to bring disease and destruction. It was said to have a skinless, skeletal appearance, glowing eyes, and the ability to curse anyone who saw it.
The Real-Life Inspiration
- Goblin Shark (Mitsukurina owstoni) – With its elongated snout, nightmarish jaws, and eerie pinkish skin, the goblin shark looks like something out of a horror movie. This deep-sea species may have washed up on shores, leading to tales of grotesque sea demons.
- Dead or Decomposed Marine Animals – Carcasses of whales, dolphins, and even deep-sea fish with bizarre features may have been mistaken for monsters by ancient sailors.
Where to See It in Bohol:
- Goblin sharks are rarely seen, but deep-sea explorations around the Bohol Sea trench could hold the key to encountering one.
The Kapre of the Ocean – The Shadowy Guardian of the Depths
The Legend
In Philippine folklore, the Kapre is a tree-dwelling giant that watches over the forests. Some variations suggest that ocean-dwelling Kapres exist, acting as mysterious guardians of the deep, watching over divers and sailors.
The Real-Life Inspiration
- Whale Sharks (Rhincodon typus) – Enormous but gentle, these massive creatures glide through the ocean with an almost mystical presence. A sudden appearance of a dark, towering shape underwater may have sparked legends of sea guardians.
- Manta Rays – Their wide wingspans and shadowy forms could easily be mistaken for mythical creatures silently gliding beneath boats.
Where to See It in Bohol:
- Pamilacan Island and Balicasag Island are known for whale shark and manta ray sightings, particularly during their migration season (November to March).
