Meet the egg-yolk jelly

Like a large bird egg cracked and poured into the water, this jelly's three-foot, translucent bell is yolk-yellow at the center with hundreds of tentacles clustered around the margin. The egg-yolk jelly is one of the larger species of jellies commonly found in Monterey Bay. This massive jelly usually drifts motionless or moves with gentle pulsing. Acting like an underwater spider web with a mild sting, an egg-yolk jelly captures other jellies that swim into its mass of tentacles.

Conservation

Many animals rely on egg-yolk jellies and other gelatinous creatures for food—including sea turtles, at least 50 species of fishes (like the ocean sunfish) and marine birds (like the northern fulmar). These animals can mistake a plastic bag for a jelly, and then get sick or die when they eat it. Help keep harmful plastic and other trash out of the sea. One simple way is by using cloth or paper bags instead of plastic when shopping.

Conservación

Muchos animales dependen de las medusas huevo frito y otras criaturas gelatinosas para alimentarse, incluyendo las tortugas marinas, al menos 50 especies de peces (como el mola) y aves marinas (como el fulmar boreal). Estos animales pueden confundir una bolsa de plástico con una medusa y enfermarse o morir al ingerirla. Ayuda a mantener el plástico dañino y otros desechos fuera del mar. Una manera sencilla es usar bolsas de tela o papel en lugar de plástico al hacer compras.

Cool facts

  • Egg-yolk jellies sometimes carry passengers. Crabs and amphipods have been found hitchhiking inside and on top of their bells. Young jack fish often can be found swimming among their tentacles.

Datos interesantes
