hhh crab

are the eels safe? - yes. this was a temporary situation with all of them in the same tank. they no longer live together and aren’t even owned by the person who put them together to begin with

why are they gasping? - that’s how they push water over their gills when sitting still

why are they all in the same cave?? are there not enough hiding places??? - this was during a water change of a 220 gal tank. they had room to separate, but were agitated at the time due to disturbance from the water change

Do you ever feel… like a plastic bag drifting through the sea? You might relate to the glass octopus (Vitreledonella richardi). This cephalopod can be found in tropical and subtropical waters around the world. Named for its transparent skin, it inhabits depths of around 3,000 ft (914 m) where sunlight doesn’t penetrate. Scientists think its see-through appearance is a form of camouflage that protects it from predators and conceals it from prey!

'ahi | yellowfin tuna

The ʻahi is a symbol of abundance. Their presence reflects the generosity of the ocean, often watched over by the akua (god) of fishing.

he'e | octopus

For many ʻohana (families), the heʻe is also recognized as an ʻaumakua, an ancestral guardian that offers protection and guidance.

mōlī | Laysan albatross

The Hawaiian mōlī (Laysan albatross) is seen as a messenger, carrying ʻike (knowledge) across great distances.

In Hawaiian culture, many ocean animals are revered as aumakua, ancestral guardians that protect the ‘ohana (family). Their presence is deeply embedded in moʻolelo (stories) and often symbolizes virtues like strength, endurance, and resilience. This profound appreciation represents a spiritual interconnectedness and respect between humans and the sea.

Did you know that tuna literally cannot stop swimming?

Unlike most fish, they lack the ability to pump water over their gills and must constantly swim with their mouths open just to breathe. These top ocean predators are vital to marine ecosystems. Atlantic tunas are also built for speed! With torpedo-shaped bodies, species like the albacore can race through the water at more than 50 miles per hour. Even cooler: Bluefin tunas are warm-blooded, which gives them the muscular power to thrive and hunt in both arctic and tropical waters.

Ever seen a giant horse conch (Triplofusus giganteus)? 👀Growing up to 2 ft (0.6 m) in length, this massive gastropod is the largest marine snail in the Atlantic Ocean. This mollusk uses its fleshy foot to envelop unsuspecting prey, including invertebrates like clams and other snails. Individuals from this species can survive for up to 30 years.
