Friday Fellow: Colorful Sidegill Slug

by Piter Kehoma Boll

[leia em português]

Some species are so peculiar and cute that they look like real-life Pokémon (well, at least what Pokémon used to look like back in the first generations). One of those species is Berthella martensi, the colorful sidegill slug.

Inhabiting the Indo-Pacific, from the intertidal zone up to a depth of about 25 m, the colorful sidegill slug measures about 5 to 6 cm in length as an adult and is often found in shallow lagoons in coral reefs. It is a pleurobranch, a group of sea slugs with an external gill located on the right side of the body, in contrast to the more famous nudibranchs, which have it on the back.

The colorful sidegill slug has a prominent mantle that extends in the form of large lobes covering its body, including its gill. These lobes can be autotomized when the animal feels threatened so that it can escape and leave the predator behind with a small snack to get distracted. But the colorful sidegill slug is a predator itself, feeding on sponges and, according to some sources, also ascidians.

But certainly one of the most remarkable features of the colorful sidegill slug is the variety of different color patterns that the species can present. It can be light cream, almost white, or dark purple, almost black, with many colors in between, such as yellow, orange, red, or purple-gray. Besides the background color, there are often several spots that are of a lighter color in dark-colored animals and of a darker color in light-colored ones. Specimens with a light background color can also have a dark margin on the mantle lobes, usually with the same color as the spots, although this is not always present. In dark-colored ones, the margin has always the same color as the background.

Despite its beauty and cuteness, the colorful sidegill slug is one more species whose ecology is almost completely unknown to us. Even though it has a charismatic look, no one cared to get to know it better until now.

The bat folk songs: cultural evolution in our winged relatives

by Piter Kehoma Boll

For a long time, culture was considered a human trait, but nowadays we recognize the existence of culture in many other species, such as other primates, whales and some birds too. Now there are some evidences of culture being found in bats too.

A group of researchers from China studied the calls of the Chinese rufous horseshoe bat (Rhinolophus sinicus) across different populations and compared them to genetic and environmental variables to determine whether the differences where linked to genetic differences between the populations or to different environments that would force the bats to change their calls in order to use them more successfully.

The results indicate that none of those two factors were strongly linked to the acoustic differences in the calls. The most likely explanation is that the differences happen due to cultural drift. The bats are teaching a way to speak to their children that is slightly different from what their neighbors speak, even if the neighbors are genetically similar and live in a similar environment.

As an animal’s call is an important variable during mating, this may eventually lead to reproductive isolation even without genetic differences. Culture can also shape evolution!
