Because  their  tissue  are hypotonic with  marine  environment  Jellyfish  are  Marine  habitat. The  solution  inside the cell  contain  fewer  solute  than  outside  solution (  marine water)  The  jellyfish cell  losses  water  through  osmosis. In  addition  these  cells  gain electrolytes  by diffusion.
