The toothy goby or common ghost goby ( Pleurosicya mossambica ) lives among soft corals and sponges in the Indo-Pacific ocean. The relationship it has with its host is commensal , which means the goby benefits from the protection and habitat in the corals, but the coral doesn't get hurt or benefit from the relationship. Many of the other 2000 or so species of gobies form such symbiotic...Read more

All squid species have long been thought to lay their egg clusters on the sea floor and move on. Then in 2005, scientists from the Monterey Bay Aquarium Research Institute (MBARI) observed a deep-sea squid species ( Gonatus onyx ) that keeps close watch over her eggs . Suspended from the squid's arms by hooks, the female squid carries her brood of roughly 3,000 eggs with her to keep them safe at...Read more

Researchers with the Smithsonian's Deep Reef Observation Project (DROP) collected this sea toad, Chaunax pictus , off the coast of Honduras in 2011. The team is trying to collect sea toads from around the Caribbean to better understand the group's genetic diversity and distribution. You can see videos and read about the DROP team's other explorations on the " Summer in a Sub " blog series.Read more

The Eastern cleaner-clingfish ( Cochleoceps orientalis ) has its job title in its name: “cleaner.” They prove invaluable to larger fish by removing parasites to keep the larger fish clean and healthy. To do their job, Eastern cleaner-clingfish move by clinging onto different surfaces instead of swimming themselves. They can hold onto kelp or sponges with a strong grip before moving onto a fish...Read more

Like other cephalopods, the common cuttlefish ( Sepia officials ) is no dummy. But while octopuses are quick to learn manual tasks like opening jars, cuttlefish have a different skillset: the social. Unlike other cephalopod species, cuttlefish are very social and interact with each other frequently, like humans, and have sophisticated communication ability.
