The family Scorpaenidae includes a number of the world’s most venomous fish species. The scorpionfish in this photo has a painful sting if you happen to be unlucky enough to come into contact with one of its spines. The pain caused by its cousin, the stonefish, can be so painful that the body goes into shock and may die.

Tunicates

Although tunicates may at first glance appear to be related to sponges or sea anemones, they’re actually in the same phylum as humans and other vertebrates – Chordata. In their larval form, tunicates look like tadpoles, with a notochord and nerve chord (which become the spine and spinal cord in vertebrates).
