The ecology of mantas and echeneids in the Tropical Eastern Pacific is poorly understood. In this study we describe the frequency of interactions between the vulnerable Mobula birostris and its symbiont Remora remora based on observations of scientists and tourists in a marine protected area. Data were obtained by analysing underwater photographs of observed mantas with remoras over 139 diving days at sea during the period 2016–17. In all, there were 271 photographic records of this symbiosis, corresponding to 207 mantas, with a mean (±s.d.) of 1.6±0.6 remoras per manta. This study is the first to provide information regarding the sex ratio, length, morphotype frequency and echeneids per manta of M. birostris in the Tropical Eastern Pacific.

The first taxonomic descriptions of the sponge diversity at El Pelado Marine Protected Area in the province of Santa Elena, Ecuador is reported. Tedania (Tedania) ecuadoriensis Jaramillo & Hajdu, sp. nov. is described from its shallow waters. In addition, Callyspongia (Callyspongia) aff. californica (sensuCruz-Barraza and Carballo 2008; nonsensuDickinson 1945) and Cliona aff. euryphylle are reported for the first time. The former species is likely distributed over 4,000 km along the Tropical Eastern Pacific, whereas the latter might be an example of a trans-isthmian lineage. An amended diagnosis for Callyspongia (Callyspongia) and an updated identification key for the subgenera of Callyspongia are provided.

Abstract During the austral winter, G-stock humpback whales, Megaptera novaeangliae, migrate to the Tropical Eastern Pacific to breed. To analyse if the whale migration times have changed over time, we analysed 31 years (1988–2018) of arrival and departure times to Gorgona National Park, Colombia, an important breeding site. During this period, whales have significantly changed their arrival time, coming now earlier, but their departure time has not changed significantly. Hence, humpback whales now stay 1 month longer than 31 years ago. Humpbacks arrived in Gorgona at the earliest during the beginning of May and stayed at the most until late December. The change observed in the arrival time to breeding grounds could be related to ice sheet mass changes in autumn in Antarctica and increase in population size over the past decades but we were unable to determine which factor is more important in explaining the observed trend. Management decisions in Colombia need to account for a longer stay, specifically restricting anthropogenic activities from 1May to 31December. We urge other researchers to review their data, in case this shift is evident in other regions and management plans need to be updated.
