Fact Friday
“Til death do us part.” It’s common to find fish that mate for life in a coral reef ecosystem. French angelfish exhibit permanent, monogamous breeding pairs. Mating for life comes with benefits. These fish cooperatively feed and defend their territory from other fish. This is much easier to do with two fish, rather than one.

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).
