*3.2. Animal Material*

Specimens of *B. excavatum* were collected in June 2017 by hand with self-contained underwater breathing apparatus (SCUBA*)* divers off the coast of Lanyu Island (Orchid Island), Taiwan. The samples were then stored in a –20 ◦C freezer until extraction. A voucher specimen was deposited in the National Museum of Marine Biology and Aquarium, Taiwan (NMMBA-TW-SC-2017-418). Identification of the species of this organism was performed by comparison as described in previous publications [1–4].
