Hi people, if any of you guys have endless ocean I'd be grateful for help with the following

1 - In the abyss there are a number of species (a large shark, anglerfish and eel) that no matter how long you pet them, feed them etc never reveal any information about themselves and remain as ???.

2 - Some of the small fish (the ones you have to zoom in on) disapear into their holes as soon as you touch them, therefore being unable to discover what they are.

Any ideas on how to get the species information for the two listed above?

Thanks
