The Valentinni’s toby is also called the black-saddled toby or Valentini puffer. Tobies or sharpnose puffers are, as their name suggests, part of the pufferfish and porcupinefish family. Many tobies, including the Valentini’s toby, release a toxic glandular secretion from their skin that repels predators. Another fish, the harmless blacksaddle filefish, mimics the Valentini’s toby and swims along with them pretending to be toxic!

Also called the cube or dice boxfish, yellow boxfish are cube-shaped, becoming more elongated as they get older! They are solitary and always seek shelter. Like their relatives cowfish, their body is encased in a protective, rigid case of fused bony polygonal plates with gaps for the mouth, eyes, gills, anus and fins. Side fins are used like oars to swim. They secrete a highly toxic substance (ostracitoxin) from their skin to protect themselves.
