- ‘Maternal and paternal brooding roles are reversed in these groups, with females producing large telolecithal eggs that are fertilized as they are deposited into the male brood pouch.’

- ‘Teleost eggs are telolecithal, with the yolk segregated from the active cytoplasm.’
Late 19th century: from Greek telos end + lekithos egg yolk + -al.
