The leafy seadragon is a spectacular Australian marine fish named for its leaf-like appendages, which provide remarkable camouflage among seaweed. Related to seahorses and pipefish, it drifts with ocean currents and uses its long snout to suck up tiny crustaceans. Remarkably, males carry the eggs.

Been carving megalodon teeth from sea glass — they’re turning into strange little relics from an ocean that never existed

Apologies got rid of the AI Slop, I have a huge amount of sea glass I collected in Cornwall and a few months ago decided to carve them, so far have done skulls, feathers, leaves etc but thought I would give shark teeth ago, alot of the glass I had were naturally that shape so went from there, thanks for looking! 😁

Octopus dilemma.

Filipino fishermen found himself in a sticky situation when an octopus tenaciously latched onto his face.

What would you do if that was you?

🔥 One of the ocean’s strangest beauties—the ribbon eel. Its vivid colors make it almost impossible to mistake for anything else.

¿Qué animal es este? What animal is this? Visto en la costa norte de Tenerife (Los Dos Hermanos) en agosto. Spotted in the rough surf off northern Tenerife (Los Dos Hermanos).

Hi everyone! I filmed this near the rocky coast of Los Dos Hermanos in northern Tenerife in mid-August around 7h30pm.
At first I thought it might be a big fish, a dolphin, or even a shark but the movement in the rough surf is quite puzzling. Any biologists, researchers, or experts who could help? Any ideas what creature this could be? 

¡Hola a todos! Grabé esto cerca de la costa rocosa de Los Dos Hermanos, en el norte de Tenerife, a mediados de agosto sobre las 19:30. Al principio pensé que podría ser un pez grande, un delfín o incluso un tiburón, pero el movimiento en el fuerte oleaje resulta bastante desconcertante. ¿Algún biólogo, investigador o experto que pueda ayudar?
¿Alguna idea de qué criatura podría ser?

-An “asterias rubens” sea star
-Multiple caridean shrimps

And some small unidentified fish.

Anemones at the National Aquarium. Baltimore, MD.

Original photo by me. Taken with Nikon D3400 and edited with Lightroom. These anemones were awesome and I knew I had to get a closer look.
