All sealife is in danger
some dolphins are in danger like the river dolphin but the bottle-nosed dolphin is luckily one that is not on the dangered list
Dolphins are so sweet. They save people whenever they are in danger and they are very protective.
Sealife gets tangled up in it and it cuts through them or drowns them (in the case of dolphins and the like) and they die.
because they send like a wave out and it comes back if there is a another fish or attacker coming
Dolphins are warm blooded like other mammals.
yes
They Breathe, with lungs, through a blowhole, like all other Dolphins.
No, common dolphins do not migrate like other species of dolphins do. However, they will move locations if they are in search of food.
dolphins get energy by eating different foods like squid fish and other animals
I don't think dolphins and bats talk to each other much. Bats live on land and dolphins live out at sea.
Bad things,like bad monsters
Just like every other mammal
